Hyaluronic Acid and Skin

The main benefits of hyaluronic acid come from its role as a humectant: it attracts water and helps hold it in the skin. Applied topically, hyaluronic acid benefits the skin by drawing moisture into the upper layers, which can help skin look plumper, feel more comfortable and appear smoother. Because well-hydrated skin reflects light more evenly, it is also associated with a fresher, more radiant-looking complexion. It does not exfoliate or resurface, so it is generally well tolerated alongside more targeted anti-ageing skincare.

Hyaluronic acid is one of the more universally suitable skincare ingredients. It is lightweight, non-occlusive and does not typically cause congestion, which makes it a good choice for oily or combination skin, as well as in skincare for dry skin. If your skin is very dry, it is especially recommended to follow with a hyaluronic acid serum with other moisturisers to help seal the hydration in place.

Hyaluronic acid molecules come in different sizes. Higher molecular weight forms sit closer to the skin's surface, where they hold water and give an immediate smoothing, plumping effect that can soften the look of fine lines when included in dedicated skincare for wrinkles. Lower molecular weight forms can travel further into the upper layers, where they support hydration at a deeper level. Many formulas combine several molecular weights so that both effects are covered in a single product.

If you have skin that feels tight or looks dull, hyaluronic acid is a good place to start. The best time to apply hyaluronic acid is after cleansing, while the skin is still slightly damp, and before richer creams or oils. The Liftactiv Hyaluronic Acid Anti-Wrinkle Day Cream is a one-step daily moisturiser with hyaluronic acid that can be used alone or layered over one of the Vichy Liftactiv serums.

Yes. Hyaluronic acid pairs well with most actives and is often used specifically to help support comfort when introducing stronger ingredients. Applying a hyaluronic acid serum before retinol night creams, or using a hyaluronic acid moisturiser afterwards, is a common approach for supporting hydration. Niacinamide skincare and hyaluronic acid are also compatible and are frequently formulated together.

Serums generally carry a higher concentration and are designed to be applied directly to cleansed skin, which makes them the more targeted option. Day creams combine hyaluronic acid with emollients and occlusives that help hold moisture in, which suits drier skin or cooler months. Many routines use both: a serum for concentration, followed by a moisturiser to seal it. For the delicate eye area, choose dedicated eye creams over harder-to-contain serums.
