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%.

Anti-aging
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).
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
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
Anti-oxidation
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.
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
Might be helpful in neutralizing free radicals. Can have a dehydration effect that might somewhat decrease the look of puffy eyes
Evens skin tone
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).

Moisturizing
What does the product description say?
Rosaliac Uv Light Anti-Redness Moisturiser SPF15
Source: From product name
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.
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
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
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
Helps soften the upper layer of the skin and create a nice product texture
Helps soften the upper layer of the skin without creatng a greasy finish
A silicone that serves as an emollient. Helps create a nice non-greasy feels
Helps preserve products and creates a nice product texture
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
Forms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness
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.
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
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.
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
