All 117 ingredients we track.

Speeds up how fast your skin renews itself so old, dull cells shed faster and fresher skin shows through. Builds collagen over time, smoothing fine lines.

The prescription-strength version of retinol. Same goals (smoother, more even skin), but works faster and is more irritating. Needs a doctor.

A gentler prescription retinoid that focuses on clogged pores and acne. Better tolerated than tretinoin for most skin.

Works like retinol but converts faster on your skin, so results come sooner with less irritation.

A multitasker that calms redness, evens out skin tone, and helps oily skin balance out. One of the safest do-a-little-of-everything ingredients.

Brightens dull skin and helps fade dark spots. Also defends against everyday UV and pollution damage when worn under sunscreen.

A gentler, more stable form of vitamin C. Same brightening benefits with less chance of stinging.

Goes into your pores and dissolves the oil and dead skin clogging them. Best for blackheads, whiteheads, and oily, acne-prone skin.

Exfoliates the surface of your skin to smooth rough texture and fade dullness. The strongest of the AHAs, so start slow.

A gentler exfoliator that also hydrates as it works. Good entry point if you have sensitive skin and want to try acids.

The slowest, gentlest exfoliating acid. Resurfaces with the least irritation, especially friendly to sensitive and deeper skin tones.

Calms redness, fades acne marks, and clears bumps, all without aggravating sensitive skin. Pregnancy-safe.

A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.

Refills the natural barrier between your skin cells. Locks moisture in, keeps irritants out, calms dry or damaged skin.

A lightweight oil that mimics what your skin already makes. Softens and seals in hydration without feeling greasy.

A plant-based alternative to retinol. Smooths fine lines and evens tone with much less irritation, making it safer for sensitive skin.

Kills the bacteria that cause inflammatory acne. The first thing to reach for when you have red, painful pimples.

A physical sunscreen that sits on top of your skin and blocks UV. Broad-spectrum and gentle enough for sensitive or rosacea-prone skin.

Another physical sunscreen that blocks UV. Often paired with zinc oxide for full sun protection.

The gold-standard fade ingredient for dark spots and melasma. Prescription-only and meant for short-term use under a dermatologist.

Fades stubborn dark patches like melasma and deep marks left behind by acne or hormonal shifts. The one to reach for when other brighteners haven't worked.

Signals your skin to make more collagen. Quiet but real support for firmness and fine lines with consistent daily use.

A Korean-skincare staple that hydrates, soothes, and helps surface damage heal faster. Especially nice on dehydrated or post-acne skin.

Also called "cica," it calms redness, repairs the skin barrier, and speeds up healing. The go-to for irritated or reactive skin.

A purified compound from the cica (centella) plant, laser-focused on calming inflammation and speeding up how fast skin heals.

Another cica (centella) compound. This one specifically pushes collagen production, so the benefit is more about firmness than calming.

A bee-made resin that's antibacterial and anti-inflammatory. Calms breakouts and hydrates at the same time.

A yeast-based ingredient that brightens skin tone and refines the look of pores. Made famous by SK-II essences.

A probiotic-based ingredient that strengthens your skin's defenses against irritation and environmental stress.

A Korean botanical that calms angry, reactive skin. Especially soothing during flare-ups.

A calming K-beauty botanical that's also antibacterial, so it pairs well for acne-prone, sensitive skin.

A heavy-duty hydrator that also reduces irritation. Often called "better than hyaluronic acid" for sensitive skin.

Pro-vitamin B5. Deeply hydrates and helps repair the skin barrier, calming dry or compromised skin.

A Korean-approved anti-wrinkle ingredient that encourages collagen production for a smoother, firmer look.

A safer, slower-acting alternative to prescription-strength dark-spot faders. Built for long-term use without irritation.

A brightening ingredient derived from fungi that fades dark spots and evens skin tone.

The mildest exfoliating acid. Refines texture and hydrates at the same time, and it's sensitive-skin friendly.

A gentle smoother and skin-soother. Reduces flakiness and helps the surface look more even.

A traditional Japanese brightener with built-in antioxidants. Softens, hydrates, and adds glow.

SK-II's signature ingredient, a specific yeast filtrate that improves clarity and texture over time.

A powerful pink antioxidant from algae. Defends against UV and environmental damage.

A lightweight Japanese plant oil that hydrates and seals in moisture without feeling heavy.

A citrus-derived antioxidant from Japan that brightens and protects the skin surface.

Fermented soy compounds that fight environmental damage from sun and pollution while gradually supporting skin firmness.

A traditional Japanese botanical (Job's tears) that hydrates and calms irritated skin.

A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.

Calms irritation and adds light hydration. The classic for sunburned or reactive skin.

A workhorse antioxidant that defends your skin from daily oxidative damage. Pairs especially well with vitamin C, and it's in nearly every good moisturizer for a reason.

Tightens and brightens the under-eye area, reducing the look of puffiness by constricting tiny blood vessels. Best deployed in eye creams.

Boosts the effectiveness of vitamin C and vitamin E when layered together. The reason a good morning antioxidant serum stays potent through the day.

A gentle Asian-skincare brightener derived from licorice root. Fades dark spots and calms redness, and it's a pregnancy-safe alternative to stronger fade ingredients.

A signal peptide that tells your skin to make more collagen and elastin. Quiet but consistent firmness support over months of daily use.

A "master antioxidant" your body already makes. In skincare it gently lightens overall tone and helps fade pigmentation when used consistently over months.

A grape-derived antioxidant that defends skin from daily oxidative damage and helps even out tone. Often paired with vitamins C and E in nighttime serums.

A naturally-occurring antioxidant your skin loses as you age. Topical CoQ10 restores some of what time depletes, supporting energy production in skin cells and softening wrinkle depth.

Sometimes called "topical Botox," it's a peptide that subtly reduces the depth of expression lines around the eyes and forehead when used daily over months. Mild effect, but real.

A polyphenol from green tea that calms UV-triggered redness and reinforces your sunscreen as a second line of antioxidant defense.

A vivid orange plant oil packed with omega-7. Calms reactive, atopic-prone skin and helps refill the lipid barrier without feeling heavy.

A gentle brightener that fades dark spots while quietly boosting hydration. Pairs especially well with niacinamide.

A hydrator often pitched as "stronger than hyaluronic acid." It sits on the surface, locks water in, and helps your skin make more of its own moisturizers over time.

A desert-bacteria-derived molecule that wraps skin cells in a protective water layer. Genuinely helpful for irritated, atopic-prone, or post-procedure skin.

A potent antioxidant from mushrooms that your skin actively pulls into cells. Quietly defends against UV damage from the inside of the cell, not just the surface.

A potent dark-spot fader long favored by dermatologists. Pairs strongly with niacinamide for stubborn discoloration without the irritation of hydroquinone.

A natural acne spot-treatment that kills the bacteria behind red, painful pimples. Slower than benzoyl peroxide but with fewer side effects when used at 5%.

A small molecule your skin already makes. Low concentrations deeply hydrate dry skin; higher concentrations soften thick, scaly patches. A workhorse for eczema and ichthyosis.

Often pitched as the gentler cousin of hyaluronic acid. It holds water in the skin, fades less quickly in dry air, and quietly buffers against UV oxidative stress.

A supplement (and topical) that adds an internal layer of sun protection on top of your sunscreen, popular for melasma and easily-burned skin. Not a sunscreen replacement, but a real adjunct.

The "calm-down" molecule in many sensitive-skin formulas. Reduces redness and stinging without bleaching your barrier, and plays nicely on top of retinoids or exfoliating acids.

A lab-engineered version of CoQ10 that gets deeper into skin cells. Modest visible improvements over months. Comparison studies place it below vitamin-C-plus-ferulic combos, but it's useful when C is poorly tolerated.

A dry oil that absorbs quickly and brings a tiny trickle of vitamin-A-like activity. Good for scarring, post-acne marks, and barrier rebuild without feeling greasy.

A rich, fast-absorbing oil for very dry or mature skin. Clinically tested as gentle on sensitive complexions, with mild brightening from its polyphenols.

A botanical with real clinical wins for irritated, post-procedure, or healing skin, including faster cesarean-wound closure in a randomized trial. Gentle enough for diaper rash; useful for eczema flares.

The classic "tea-bag-on-puffy-eyes" botanical. Calms angry skin via the same anti-inflammatory pathways psoriasis drugs target, just gentler. Good for reactive or rosacea-prone complexions.

Replenishes one of the actual humectant molecules your own skin makes. Levels drop in eczema and with age, so topping it up genuinely helps dry, dehydrated, or atopic-prone skin feel less tight.

An "adaptogen" mushroom that helps skin cells handle stress at the gene level. Early-stage evidence but mechanistically interesting for anti-aging routines layered with vitamin C or peptides.

A "next-gen AHA" that exfoliates and hydrates at the same time, with much less stinging than glycolic. Sensitive-skin or rosacea-prone users tolerate it where stronger acids fail.

A "postbiotic" (dead probiotic bits) that talks to your skin microbiome without adding live bugs. Patches up a leaky barrier and is friendly even on very reactive skin.

The protein your skin loses with age, broken down small enough to absorb. Multiple meta-analyses of RCTs show measurable wins in wrinkles, elasticity, and hydration after ~12 weeks. Most evidence is oral, but topical helps surface hydration too.

The "salmon DNA" trending in K-beauty and Korean clinics. Strong wound-healing pedigree translated into anti-aging. Speeds repair after lasers/microneedling, smooths fine lines, and brightens. Often layered with vitamin C and niacinamide. Worth knowing: salmon- or trout-derived PDRN has much stronger clinical evidence than plant ("phyto") PDRN, and the dose matters more than the marketing — favor products that list a real PDRN concentration (roughly 1,000+ ppm) over big headline numbers on plant-derived versions.

The Moroccan kitchen-staple oil with real cosmetic data behind it. Daily use measurably improves skin elasticity in postmenopausal women. Good for dry, mature, or barrier-compromised skin without feeling greasy.

Technically a wax that masquerades as oil, molecularly closer to your own sebum than any other plant oil. Hydrates without clogging pores, calms inflammation, and plays well in acne-prone and sensitive routines.

A traditional Polynesian "first-aid oil" with real cell-culture and animal data for wound repair and scar fading. Good as a spot treatment on healing blemishes, post-procedure skin, or stubborn dry patches.

Vitamin E's more potent cousin, better at chasing down free radicals and shielding skin from UV-driven aging. A systematic review concluded it protects against inflammation, UV damage, and pigmentation; pairs naturally with vitamin C.

A "molecule your own immune cells make," now bottled. Kills surface bacteria without nuking the barrier, calms itch and redness in eczema, and gives compromised or post-procedure skin a clean reset, gentle enough to spray around eyes.

A "natural skin lightener" with actual clinical-trial backing for melasma. A placebo-controlled study showed real MASI improvement. Sits well alongside vitamin C, alpha-arbutin, or niacinamide in a brightening stack.

A pharmacy-grade skin protectant proven to calm itch, redness, and dryness in eczema and other irritated skin. FDA recognised it as a Category I skin protectant in 2003, and 1% creams beat vehicle in mild-to-moderate atopic dermatitis trials.

The gold-standard occlusive moisturiser. Locks water into damaged or compromised skin better than anything else, accelerates barrier repair, and (in newer research) actively boosts your skin's own antimicrobial defences. Cheap, non-allergenic, dermatologist-recommended for eczema, post-procedure care, and slugging.

A silicone that sits on your skin as an invisible, non-greasy shield. Reduces water loss, protects against irritants (think soap, friction, incontinence), and is FDA-recognised as a skin protectant from 1-30%. The reason your favourite primer feels silky and your barrier cream actually works under makeup.

A rich, naturally occlusive plant butter from the African karite tree. Calms eczema-prone skin, refills the lipid barrier, and (in randomized trials) is acceptable and effective enough that three quarters of pediatric AD patients use it as a steroid-sparing emollient.

The third (and most often missing) lipid in the skin barrier triumvirate. Without it, even ceramide-heavy creams underperform. Topping it up is what lets compromised, aged, or eczema-prone skin actually rebuild its waterproof layer.

An essential fatty acid your sebum runs short on if you're acne-prone, and topping it up topically literally shrinks clogged pores. Also rebuilds the lipid mortar between skin cells. Found concentrated in safflower, hemp, and rosehip oils.

Sheep-derived wax esters that mirror the molecules in your own skin lipids. Heals cracked nipples, dry hands, and damaged lips with multiple positive RCTs behind it. Note: classic but real allergen, so patch-test if you have a wool/Balsam-of-Peru history.

A wax film former that quietly does what petrolatum does (slows water loss and shields chapped skin) without feeling slick. Most evidence comes from honey/beeswax/olive-oil cerates that beat vehicle in eczema and psoriasis trials. CIR-affirmed safe.

An ancient antimicrobial that has graduated into modern wound clinics. Cochrane and meta-analytic evidence shows it heals partial-thickness burns ~4-5 days faster than conventional dressings; smaller dermatology trials show it calms atopic dermatitis flares without irritation.

The active in classic anti-dandruff and anti-Malassezia formulas. RCTs show it clears severe dandruff and seborrheic dermatitis on par with ketoconazole 2%; also useful in fungal acne and scalp folliculitis. The reason your medicated body wash actually works.

A plant-derived acid that blocks the enzyme your skin uses to make pigment, fading dark spots and post-acne marks. Clinical trials show it measurably reduces hyperpigmentation and improves skin luminosity, with significantly less irritation than stronger AHAs. A good option for sensitive skin that still wants a brightening acid.

A gentler grape-derived AHA that exfoliates and helps multi-acid formulas stay at the right pH to work. Less studied than glycolic or lactic acid as a standalone, but well-tolerated in combination peels, and the antioxidant side effect is a genuine bonus.

The most widely used chemical UVA filter in Western sunscreens, critical for blocking the longer wavelengths that drive photoaging, pigmentation, and deeper DNA damage. Always look for it paired with a photostabiliser such as octocrylene so it doesn't degrade and leave you unprotected mid-day.

The UVB workhorse behind most chemical sunscreens: effective, well-tolerated, and found in over 90% of chemical-filter formulas in the US. Important caveat: it covers UVB only, so it always needs a UVA partner (typically avobenzone). Also banned in Hawaii and reef-sensitive areas due to coral toxicity, so check the label if environmental impact matters to you.

A botanical astringent backed by real anti-inflammatory evidence. Extracts genuinely calm acne-related inflammation by blocking the same NF-κB pathway that redness-causing cytokines depend on. Honest caveat: most shelf-ready witch hazel toners are distilled water with trace tannin; look for "Hamamelis virginiana extract" rather than "hamamelis water" on the label if you want the active fraction.

A fruit-derived AHA that exfoliates and antioxidizes. It shares the same basic mechanism as glycolic and lactic acid but is weaker gram-for-gram; in practice you'll see it doing dual duty (a little exfoliation plus pH stabilisation) in multi-acid toners and serums. When it appears low on an ingredient list, it's adjusting pH; higher up, it's contributing real exfoliation.

A fatty acid from coconut oil with striking antimicrobial activity against acne bacteria. In lab tests it outperforms benzoyl peroxide at lower concentrations. The research is promising but limited to in vitro and animal models; no large human RCT yet. Worth noting: the concentrations used in the studies are far higher than what arrives via a coconut-oil facial oil, so look for formulas that list it as a dedicated active if you want the therapeutic dose.

A sticker you put over a spot overnight. It pulls out the gunk and excess oil and — just as importantly — stops you picking at it, which is half the battle with scarring. Works best on whiteheads that have come to a head, but the no-touching benefit helps any spot you'd otherwise pick at.

The "longevity molecule" of cellular skincare. It boosts NAD+ levels directly, helping your skin cells behave like younger ones. Clinical trials show it improves skin elasticity and barrier strength by activating cellular repair genes. A top pick for age-reversal routines.

A gentle alternative to acids. It uses enzymes to "eat" the glue holding dead skin cells together, leaving skin smooth without the stinging or redness of AHAs. Ideal for sensitive skin that needs surface smoothing without the downtime.

A "universal antioxidant" that protects both the oily and watery parts of your skin. It's unique because it can recycle your Vitamin C and E, making them last longer. It also prevents "sugar-sag" (glycation) and reduces fine lines.

A staple in Hanbang (traditional Korean medicine) skincare. It's packed with antioxidants and ginsenosides that help firm the skin, boost circulation, and defend against environmental aging.

Highly biocompatible "cellular messengers" that literally tell your skin cells to stop panicking and start repairing. Excellent for severe redness and compromised barriers.

Liquid microneedling in a bottle. It causes a temporary prickly sensation but creates tiny pathways in your skin so all your other expensive serums can actually penetrate deeper.

The ultimate vegan alternative to snail mucin. It provides the same deeply hydrating, stretchy texture but is derived entirely from wild yam roots. Very soothing for sensitive skin.

The ultimate "cell recharger." It boosts your skin's cellular energy to speed up repair and protect against aging at the DNA level. It's the new high-tech standard for longevity skincare.

A standout dark-spot fader. It blocks the human pigment-making enzyme more strongly than most brighteners, so with daily use it visibly lightens melasma, sun spots, and post-acne marks over a few weeks. Pairs well with sunscreen and niacinamide.

A gentler-but-effective next-generation retinoid popular in Korean anti-aging serums. In trials it smoothed fine lines and crow's-feet better than plain retinol, with less stinging — a good step up if regular retinol is too harsh. Use at night and always wear SPF.

The retinol-without-the-irritation active marketed as Granactive Retinoid. It works on fine lines and acne-prone texture with far less flaking than prescription-style retinoids, which makes it beginner-friendly. Use at night, with daytime SPF.

The exosome-facial active from Korean clinics. The strongest evidence is as a booster paired with microneedling or laser — where it improved wrinkles and tone — rather than as a stand-alone leave-on. Promising but still early; treat it as a clinic-adjacent extra, not a proven daily essential.

The overnight-repair antioxidant showing up in night creams. Small trials found melatonin creams improved texture, fine wrinkles, and tone with nightly use. A nice antioxidant layer for PM routines; pair with morning SPF for daytime protection.

The rice-water glow trend behind viral rice toners and essences. Lab and animal studies point to brightening and hydration, but human studies are still thin — so think of it as a pleasant, low-risk hydrator with promising early evidence rather than a proven brightener.
