“For women or men who want to hydrate dry exposed skin. Replenishing and soothing formula. Helps to soothe and moisturise skin.”
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.
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: butyrospermum parkii butter, dimethicone.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide, paraffinum liquidum
Anti-agingNot advertised by the brand · 3 ingredients credited for this claimStrong evidence
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.
Evens skin toneNot advertised by the brand · 1 ingredient credited for this claimStrong evidence
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 evidence
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.

Product summary
Based on the ingredient list, "La Roche-Posay - Posthelios After Sun Face and Body Gel" can work well for skin moisturization. The formulation is based on a combination of good humectants and emollients. Both are needed to increase the skin hydration level. Humectants in this product (glycerin) 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). Emollients in this formulation (paraffinum liquidum, butyrospermum parkii butter, dimethicone, cetyl alcohol and glyceryl stearate) help to reduce the moisture loss from the skin. They also soften the skin surface and relieve the feeling of dryness and tightness.
