Product Summary
The ingredient list suggests that "Sesderma - Azelac RU Luminous Fluid SPF 50" can provide reliable sun protection. We love that it can protect from both UVA and UVB rays (not all sunscreens with SPF ratings give UVA protection. UVA rays do not cause sunburn, but still damage our skin and lead to early aging).
Its formula is also hydrating, so you might not need an additional moistruizer during the day. Like all broad-spectrum sunscreens, this product helps prevent early signs of aging.
Sunscreen filters
This is a "mixed" sunscreen in the sense that it uses both mineral and organic (so-called "chemical") sun filters. The organic filters in the product are: tinosorb s, avobenzone, octinoxate, octisalate and uvinul t. As for the mineral filters, this sunscreen uses titanium dioxide.
Irritation risk
There are quite a few common irritants in this product, including ingredients without particular skin benefits. We would not recommend it for sensitive skin. We assess the overall irritancy of this moisturizer to be high. For a detailed overview of all potential irritants: click here

A vitamin C derivative that is more stable but less potent than pure form of vitamin C. Can help neutralize free radicals and help 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
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Being a lipid soluble form of vitamin C, it is more stable and can penetrate the skin better than L-Ascorbic acid. It is effective in protecting the skin from free radicals, as well as evening the skin tone, but is less effective in stimulating collagen production compared to L-Ascorbic acid.

Sun protection
This product offers a good level of protection against both UVB and UVA rays.
This sunscreen uses organic (so-called "chemical") sunscreen filters. Organic, or "chemical" filters usually provide reliable sun protection and rarely leave a white cast. Sunscreens with organic filters can sting eyes.
Tinosorb S. One of the most effective broad spectrum sunscreen ingredients. Protects from both UVA and UVB rays. It is photostable. Unfortunately, not approved by FDA (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.
Octinoxate. When used in higher concentrations, works as a sunscreen protecting the skin from UVB rays. When used in lower concentration, helps to preserve the product formulation. Is shown to be harmful to coral reefs - consider avoiding bathing in coral reef areas when wearing a product with this ingredient. It can be irritating
Uvinul T. A UV filter. Effective against UVB rays. It is photostable. Can increase water resistance properties of the sunscreen. Unfortunately, not approved by the FDA (US) yet
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
Works as a UV filter when used in high concentrations. It is photostable and is effective mostly against the UVB light, with some protection in the UVA range. In small concentrations, used for its ability to improve the color of cosmetic products. Is usually well tolerated by the skin
Moisturizing
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, bis-peg-18 methyl ether dimethyl silane.
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, cyclopentasiloxane.
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
An amino acid that is effective in reducing hyperpigmentation and evening out the skin tone. It can also help in skin barrier recovery. It is used to treat melasma, especially with injections and when taken orally
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
A silicone that helps improve the product texture and spreadability. Can absorb oil creating a short-term mattifying effect on the skin
A type of silicone that helps soften the upper layer of the skin and create a nice product texture
Used to create a nice product texture and help delivery of other ingredients. Might be somewhat helpful in attracting water to the upper layer of the skin
A silicone that forms a light film on the skin surface helping to bind water and temporarily absorb oils creating a matt and powdery feel
Helps preserve products and creates a nice product texture
An emollient that softens the skin and forms a protective layer on its surface. Helps water and oil mix together
A good mix of fatty acids that forms a protective layer on the skin. Improves the shelf life of products. Derived from coconut and glycerin
Pure form of vitamin E. Can help moisturise and protect the skin from free radicals. Often used to help stabilise other ingredients or the formula itself
Used mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin
