“Rosaliac UV Legere Fortifying Anti-Redness Moisturiser”
This product can help improve hydration of the skin with the two types of ingredients.
The first type is called “humectants”:
these ingredients help attract water.
When humectants are on the surface of the skin, they “pull in” the moisture from the outside environment, or from
within deeper layers of the skin. The following ingredients in this product do the job:
glycerin, caprylyl glycol.
This product also contains ingredients called “occlusives”. They help reduce the speed with which our skin loses moisture to the outside environment. These ingredients also help soften the upper layer of the skin, so it feels less tight and nicer to the touch. The following ingredients in this product do the job: dimethicone, dimethiconol.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide
Evens skin toneNot advertised by the brand · 2 ingredients credited for this claimStrong support
This product can help reduce hypepigmentation and even out the skin tone because it contains the following effective ingredients: niacinamide
Keep in mind that you would need to apply any topical skincare targetted at hypigmentation consistently for a couple of months to get a result. No topical skincare product can help get rid of hyperpigmentation (including post-acne marks and age spots) instantly.
Anti-blemishNot advertised by the brand · 1 ingredient credited for this claimStrong support
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
Anti-agingNot advertised by the brand · 2 ingredients credited for this claimStrong support
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.

Product summary
Based on the ingredients included, "La Roche-Posay - Rosaliac UV Legere Fortifying Anti-Redness Moisturiser" works well for moisturizing the skin. This moisturizer uses a good combo of humectants and emollients. These both types of ingredients are essentials for improving the skin hydration and keeping the skin barrier healthy. Humectants in this product (glycerin and caprylyl glycol) help to increase the water content in the upper layer of the skin. (These ingredients do so by "capturing" water molecules from the outside air or from within the deeper layers of the skin). Dimethicone, dimethiconol, diisopropyl sebacate, caprylyl glycol and isononyl isononanoate in this product help decrease the water evoporation from the skin, so that it stays hydrated for longer. These ingredients also soften the skin and take away the feeling of tightness and dryness.
Ingredient callouts
- We love that this moisturizer contains a good concentration of niacinamide 2.30% - 2.90%. Niacinamide is a perfect active in a moistruizer because it helps calm down inflamation in skin and support the skin barrier. More than that, it is helpful for most common skin concerns: it helps regulat oil production, help reduce acne and clogged pores, improve skin tone and prevent pigmentation marks. It also helps fight photodamage.
Irritation risk
