Product Summary
The ingredient list suggests that "Kerstin Florian - Correcting Multi-Vitamin Day Creme SPF 30" can provide reliable sun protection. It can protect from both UVA and UVB rays. This is great news because 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 contains good moisturizing ingredients and can double as a hydrating day cream. This product prevents early signs of aging by protecting against sun damage (all broad spectrum sunscreens do that).
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: octinoxate, tinosorb m and octocrylene. 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 sunscreen to be high. 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.
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: tocotrienols.
A type of vitamin E that is more powerful in neutralizing free radicals compared to its other forms
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.
Anti-oxidation
This product contains antioxidants (tocotrienols) that can help neutralize free radicals in skin. By doing so, they can lessen the damage the skin gets from the UV light (sun).
The following ingredients - squalene also can have an antioxidant effect, but there is less evidence to confirm their effectiveness in skin.
A type of vitamin E that is more powerful in neutralizing free radicals compared to its other forms
An oil that is naturally part of skin sebum that helps to soften its upper layer, reduce water loss and neutralize free radicals. It might be comedogenic. Avoid applying large concentrations (or pure oil) before sun exposure as oxidized squalene can clog pores and lead to skin irritation. Today squalene is mostly derived from vegetable oils or synthetized by yeast
A fruit extract that might have some anti-oxidant properties but evidence of effectiveness in skin is lacking
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
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
Might be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect
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).

Moisturizing
What does the product description say?
Correcting Multi-Vitamin Day Creme SPF 30
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, butylene 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, squalene.
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: panthenol
One of the best moisturizing ingredients. Naturally present in skin. It attracts water to the upper layer of the skin working as a humectant
Red algae extract that helps attract water to the upper layer of the skin and create a nicer product consistency
Helps attract water to the upper layer of the skin and can help improve skin barrier function
Lipids that work as an emollient and can be helpful in repairing skin barrier function
An oil that is naturally part of skin sebum that helps to soften its upper layer, reduce water loss and neutralize free radicals. It might be comedogenic. Avoid applying large concentrations (or pure oil) before sun exposure as oxidized squalene can clog pores and lead to skin irritation. Today squalene is mostly derived from vegetable oils or synthetized by yeast
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
Helps soften the upper layer of the skin
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

Helps oil and water mix together and can enhance the penetration of other ingredients into the skin. It can be irritating
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
Helps preserve products and creates a nice product texture
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
Might be somewhat helpful in reducing hyperpigmentation and neutralizing free radicals but its typical concentration in a product is too low for having an effect
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
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.
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
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 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
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
