What the product description says

“Suncut Prodefense Tone Up UV Sunscreen Stick SPF 50+ PA++++”

From product name

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).

Ascorbyl tetraisopalmitateUnder-dosedA vitamin C derivative. Studies show that is might be effective in reducing hyperpigmentation, but there are no studies confirming that it is effectively converted into the bioavailable form of Vitamin C in skin. It is not clear how this derivative compares in effectiveness to the topical application of bioavailable form of vitamin C (L-ascorbic acid)~0.75–1.1%

Anti-aging

Side benefit · Tocopherol, Ascorbyl tetraisopalmitate

Works well

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.

TocopherolEffect: Low, below effective dosePure 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~0.7–1.05%

Moisturizing

Side benefit · Paraffinum liquidum, Triethylhexanoin + 9 more

Works well

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: sodium hyaluronate.

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: caprylic/capric triglyceride, dimethicone.

The following ingredients in this product are especially good for supporting the skin barrier and helping with the hydration level: paraffinum liquidum

Product summary

The ingredient list suggests that "Kose - Suncut Prodefense Tone Up UV Sunscreen Stick SPF 50+ PA++++" 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).

It also works as a moisturizer, so you do not have to use an additional hydrating product. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.

Sunscreen filters

This sunscreen uses a mixture of both mineral and organic (so-called "chemical") UV filters. Here are the organic filters this product uses: tinosorb s, uvinul a plus and octinoxate. As for the mineral filters, this sunscreen uses both titanium dioxide and zinc oxide.

There are some common irritants in this product, including ingredients that do not have benefits for the skin. We assess the overall irritancy of this sunscreen to be high. For a detailed overview of all potential irritants: click here
