Product Summary
"La Roche-Posay - Rosaliac UV Light" 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 product is not high enough. We recommend to use a sunscreen with at least SPF 30 daily.
It also works as a moisturizer, so you do not have to use an additional hydrating product. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
Sunscreen filters
This is a so-called "chemical" sunscreen. It means that it uses organic UV filters. They typically offer good sun protection and rarely leave a white cast, but they can be irritating for some people with sensitive skin. The UV filters in this sunscreen are: avobenzone 1.40% - 1.80%, mexoryl xl 0.65% - 1.00%, octisalate 2.00% - 2.40% and octocrylene 3.60% - 4.40%.
Irritation risk
This formulation includes some common irritants, including ingredients that do not provide a benefit for the skin. We assess the overall irritancy of it to be low. For a detailed overview of all potential irritants: click here

Anti-aging
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.
Is proven to be effective in reducing blemishes, evening out skin tone and helping to improve lines and wrinkles. It helps the skin to repair sun damage, calm down inflammation and keep maintain good levels of moisture. The concentration of about 2% is effective for supporting the skin barrier and evening out the skin tone. Concentration of 4-6% is better for helping with acne and balancing the sebum production
A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Has a potential to boost collagen production, nutralise free radicals and reduce hyperpigmentation, but the required concentration is likely to be much higher than for the pure form of vitamin C, limiting the ingredient's effectiveness in products
Anti-blemish
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.

Evens skin tone
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.
This product can also help with skin tone because it offers 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).

Moisturizing
What does the product description say?
Anti-Redness Moisturiser with UV Protection A daily care product to hydrate and comfort the skin and to help reduce the appearance of redness.
Source: Beauty Expert
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
A silicone that makes products more spreadable and keeps skin smooth. Helps to add gloss to skin and may visually fill in fine lines/wrinkles for short time
A silicone that helps to reduce water loss from the surface of the skin. Can temporarily "fill in" lines and wrinkles, absorb oil, and create a nice product finish
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

Sun protection
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.
Mexoryl XL. A UV filter. Effective in the UVB and UVA range. It is stable. Unfortunately, not approved in the US yet
Avobenzone. An organic, or so-called "chemical" UV filter. Protects against both UVA and UVB rays. Needs to be combined with other filters in a formulation to be stable.
A weak sunscreen that protects against the sun rays that cause sunburn (UVB) and is somewhat effective against the UVA rays. It is quite stable and can help stabilize other, more vulnerable, sunscreen ingredients like Avobenzone. It is an organic, or so called "chemical" sunscreen
Octisalate. A UV filter. It offers some protection against the sun rays that cause sunburn (UVB), but does not protect against the most aging sun rays (UVA). It loses its effectiveness quickly when exposed to sunlight. It is an organic, or so called "chemical" sunscreen
