Evens skin tone
Not advertised by the brand · No ingredient credited for this claim
Strong evidence

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
Not advertised by the brand · Squalene, Beta-sitosterol + 7 more
Good evidence

This product can help soften the skin and reduce its moisture loss with emollients and occlusives: beeswax, cera alba.

Keep in mind that this product does not contain effective ingredients to attract water to the upper layer of the skin. This is why an additional product with humectants like glycerin or hyaluronic acid can be helpful (apply it before this product for the best results).

SqualeneKey active· Emollient, OcclusiveEffect: HighAn 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~0.15–0.6%

Product summary

We assess that "Comfort Zone - Sun Soul Stick 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).

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 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. Here are the exact UV filters in this sunscreen: tinosorb s 1.00% - 1.50%, uvinul a plus 1.20% - 1.80%, octinoxate 3.40% - 5.10% and uvinul t 0.60% - 1.40%.

Irritation risk

This formulation includes some common irritants, including ingredients that do not provide 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
