Product Summary
Based on the ingredient list, we assess that "Iwostin - Solecrin SPF50" 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).
As a plus, this sunscreen uses some of the new generation UV filters (Tinosorb M). These filters are more stable and more gentle on the skin.
It also works as a moisturizer, so you do not have to use an additional hydrating product. 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 and tinosorb m. As for the mineral filters, this sunscreen uses titanium dioxide.
Irritation risk
There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of it to be medium. For a detailed overview of all potential irritants: click here
You can see the detailed formula review with the breakdown of all actives in the product and the full ingredient list with estimated concentrations in the tables below.
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.
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
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.
Evens skin tone
This product offers broad spectrum sun protection. It means that it can prevent hyperpigmentation and help keep the skin tone even (sun damage is the main factor causing age spots, darkening of post-acne marks and other discolorations).
The most well-researched antioxidant that works in skin. Helps neutralize free radicals supporting collagen production, helping to even out the skin tone and preventing early signs of aging
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.
Tinosorb M. A UV filter. Is effective against both UVA and UVB rays. It also provides some protection against visible light. It is photostable and can also be used to improve photostability of other sunscreen ingredients. Its physical properties help to create lightweight sunscreen formulations. It can leave a slight white cast. Unfortunately, it is not approved by the FDA (US) yet
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
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
Used to improve the product adherence to the skin, for example, to pro-long the protective effect of sunscreens. Can be irritating to very sensitive 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, propylene 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, squalane.
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
An oil naturally present in skin. Works as an emollient to soften the skin and form a protective layer on its surface without a greasy feeling.

Enhances the product texture and makes it more spreadable. Helps reduce water loss from the outer layer of skin. Extands the shelf life by preventing bacteria growth
A non-drying alcohol. Works as an emollient. Helps water and oil mix together and creates a nice product texture
Used to stabilize the product formulations and works as an emollient
Helps to soften the upper layer of the skin and create a nice product texture
Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
Helps products spread more easily and works as an emollient to soften skin
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
Forms a protective film on the surface of the skin to prevent moisture loss. Gives a velvety feel to products while reducing tackiness
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
