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

What can the product work for?

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.

bis-ethylhexyloxyphenol methoxyphenyl triazine 1.5% - 1.8%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

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.

butyl methoxydibenzoylmethane 2.1% - 2.5%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

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.

methylene bis-benzotriazolyl tetramethylbutylphenol 1.7% - 2%

Irritation risk:

UVA I protection: UVA II protection: UVB protection: Photo stable: Ingredient type Organic

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

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.

ascorbic acid 0.2% - 0.4%

Irritation risk:

Concentration: Insufficient!

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

tocopherol 0.3% - 0.6%

Irritation risk:

Concentration: Insufficient!

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

ascorbyl palmitate 0.3% - 0.55%

Irritation risk:

Concentration: Insufficient!

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).

ascorbic acid 0.2% - 0.4%

Irritation risk:

Concentration: Insufficient!

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

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.

dimethicone 0.4% - 0.6%

Irritation risk:

Concentration: Effectiveness: HIGH

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

glycerin 2.2% - 2.7%

Irritation risk:

Concentration: Effectiveness: HIGH

One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant

squalane 0.45% - 0.7%

Irritation risk:

Concentration: Effectiveness: HIGH

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.
