Product Summary
We assess that "Sesderma - REPASKIN Lips SPF50" can provide reliable sun protection based on the ingredient list. 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).
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. These are the sun protection ingredients in this sunscreen: tinosorb s 3.90% - 5.90%, avobenzone 1.50% - 2.20%, uvinul t 2.50% - 3.70%, homosalate 4.80% - 7.30% and octocrylene 5.30% - 8.00%.
Irritation risk
It contains some common irritants, including those without a benefit for the skin. We assess the overall irritancy of it to be medium. For a detailed overview of all potential irritants: click here

Works for
Anti-aging
This product can help prevent early signs of skin aging because it offers a good level of broad spectrum sun protection. Sun damage is the main cause of premature skin aging, and protecting your skin from the sun is the best anti-aging strategy.
These ingredients in the product might also be helpful for reducing and preventing fine lines, wrinkles, and skin elasticity, even though there is no conclusive evidence for their effectiveness: arabidopsis thaliana extract.
Plant extract that might be helpful in repairing sun damage but evidence of effectiveness in skin are lacking
Might be helpful in neutralising free radicals in skin and have some hydration properties
Moisturizing
What does the product description say?
protective and moisturizing formula that does not leave whitish marks.
Source: N/A
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, thermus thermophillus ferment.
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: caprylic/capric triglyceride.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: lanolin, petrolatum
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Consists of remains of dead bacteria cells. Is likely helpful in attracting water to the upper layer of the skin. Might be helpful in reducing inflammation and neutralizing free radicals in skin. It is claimed to be a "DNA repair enzyme"
One of the most effective and the most studied occlusive ingredients that creates a protective layer on top of the skin preventing moisture loss
Might be helpful in neutralising free radicals in skin and have some hydration properties
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
Sebum of wool-bearing animals (most commonly sheep). Helps soften the upper layer of the skin and reduce the skin water loss. In rare cases could be an allergen. Not suitable for vegans
Helps soften the upper layer of the skin. It mostly contains oleic acid which is not the most effective emollient to prevent water loss, but might have an anti-inflammatory effect
Can help attract water to the upper layer of the skin
Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
A great moisturising ingredient that softens the skin and reduces water loss from its upper layer. It also can be helpful in protecting skin from free radicals
Used mostly for creating emulsions - helping oil and water mix together. Helps soften the upper layer of the skin
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.
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
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.
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
A weak sunscreen that offers some protection against the sun rays that cause sunburn (UVB), but does not offer meaningful protection against 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. When used in low concentrations, helps to stabilize the product formulation
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
