ISDIN Foto Ultra Redness SPF50
Works for
Sun protectionSPF 50 · 5 UV filtersBroad spectrum
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.
Evens skin toneNiacinamide, Potassium azeloyl diglycinateWorks well
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).
Anti-agingSide benefit · Niacinamide, TocopherolWorks well
This product can help reduce and prevent fine lines and wrinkles, improve skin elasticity and firmness because it contains niacinamide.
Keep in mind that it typically takes at least 6 weeks to notice any results because the changes that are needed to improve fine lines and elasticity happen in the deeper layers of the skin. No topical anti-aging product can “erase” wrinkles or fully reverse signs of aging.
This product can also 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.
Anti-blemishSide benefit · Niacinamide, Potassium azeloyl diglycinateWorks well
This product can help reduce breakouts and clogged pores because it contains the following ingredient: niacinamide. This ingredient is used for treating acne and can have a noticeable effect.
In addition, this product contains potassium azeloyl diglycinate. It can help in reducing blemishes, even though it is less effective.
MoisturizingSide benefit · Niacinamide, Coco-caprylate/caprate + 8 moreWorks
The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: niacinamide

A derivative of azelaic acid. It is obtained by reacting the chloride of azelaic acid with two molecules of glycine (an amino acid) and potassium hydroxide. It is less studied than azelaic acid, but the available research suggests that it also can be effective in reducing skin redness, hyperpigmentation and blemishes. There are claims that it is more bio-available and more effective than azelaic acid, but no comparison study is available. Potassium azeloyl diglycinate is better soluble in water compared with azelaic acid. Because of this property, products with potassium azeloyl digclycinate can have a nicer texture
