Sun protectionSPF 15 · 4 UV filters · Broad spectrumWeak protectionSPF under 30
This product offers broad spectrum sun protection, but it is weak. We recommend to use a broad spectrum sunscreen with at least SPF 30.
This product can be considered "reef safe" because it does not contain the UV filters (oxybenzone and octinoxate) that can be harmful to coral reefs when present in the water in high concentrations.

“Rosaliac Uv Light Anti-Redness Moisturiser SPF15”
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.
Evens skin toneNot advertised by the brand · 2 ingredients credited for this claimModerate support
The following ingredient (ingredients) in this product might be helpful, but there is no evidence to confirm that it actually works: ascorbyl glucoside.
The biggest effect for evening out skin tone in this product comes from sun protection. Sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations. This is why sun protection is the best strategy for maintaining an even skin tone. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).
Anti-oxidationNot advertised by the brand · 2 ingredients credited for this claimModerate support
This product contains antioxidants (ascorbyl glucoside) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
Anti-agingNot advertised by the brand · 2 ingredients credited for this claimModerate support
This product contains ascorbyl glucoside. This ingredient might be able to help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness, but there is not enough evidence that it actually works. The biggest anti-aging effect in this product comes from sun protection. Sun damage is the main factor causing early signs of skin aging. We, however, do not recommend using this product as a sunscreen because the protection it offers is not strong enough).

Product summary
"La Roche-Posay - Rosaliac Uv Light Anti-Redness Moisturiser SPF15" offers broad spectrum protection. It means that it protects from both UVA and UVB rays (you can remember UVB as "burning" sunlight - they cause sunburn. You can remember UVA rays as "aging" - they do not lead to sunburn, but they cause photodamage and contribute to early signs of skin aging and hyperpigmentation). On the negative side, the SPF of this moisturizer is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.
Because it includes good moisturizing ingredients, it can also work as a hydrating day cream.
Sunscreen filters
This sunscreen uses so-called "chemical", or organic UV filters (organic simply means that their molecules contain atoms of carbon). These filters typically give good sun protection and rarely leave a white cast, but they can be irritating for sensitive skin. Here are the exact UV filters in this sunscreen: avobenzone 4.00% - 5.90%, mexoryl xl 0.55% - 1.35% and octocrylene 0.45% - 1.00%.
Irritation risk
