What does the 50X smaller micro hyaluronic acid mean?

L'Oréal says its hyaluronic acid fragments are 50 times smaller than standard molecules, which the brand claims lets them penetrate further into the skin surface for hydration. It is still a humectant that draws in water, not an exfoliant or retinoid.

How do I use it in a routine?

Apply a few drops to clean skin morning and night, then follow with moisturizer. In the morning, finish with sunscreen, since the serum has no SPF.

Is it suitable for sensitive skin?

The formula is fragrance free, paraben free and alcohol free, which removes common irritants. Hyaluronic acid is generally well tolerated, but patch test first if your skin reacts easily.

How does it compare with other Revitalift serums?

This is the plain hyaluronic hydrating serum. Other Revitalift serums add actives such as vitamin C or pro-retinol for brightening or firming, so choose this one if you want hydration without those extras.

Will it reduce fine lines?

L'Oréal claims a 60% reduction in fine lines with daily use. Most of the immediate effect is plumping from hydration, so expect gradual change over weeks rather than overnight results.
