Needle-less® Growth Factor Serum
What it's good for
Key actives from our research database. Click any to read the full evidence dossier.
Refills the natural barrier between your skin cells. Locks moisture in, keeps irritants out, calms dry or damaged skin.
Good for: Barrier repair
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.
Good for: Barrier repair
A workhorse hydrator that pulls water into your skin. In nearly every good moisturizer for a reason.
Good for: Hydrating
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
Good for: Hydrating
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.
Good for: Hydrating, Antioxidant, Barrier repair
