Hyaluronic Acid vs Squalane
Which is right for your skin?
Different jobs: hyaluronic acid pulls water into skin (a humectant), squalane seals moisture in and softens (an emollient). Hyaluronic on damp skin, squalane on top. Partners, not rivals.
A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
A lightweight oil that mimics what your skin already makes. Softens and seals in hydration without feeling greasy.
Can you use Hyaluronic Acid and Squalane together?
Yes, Hyaluronic Acid and Squalane are documented to pair well together.
You want hydrating. A pure hydrator that holds water in your skin. Makes skin look plumper and smoother almost immediately.
You want barrier repair, hydrating. A lightweight oil that mimics what your skin already makes. Softens and seals in hydration without feeling greasy.
