COSRX Shield Fit All Green Comfort Sun SPF50+ PA++++
Works for
Sun protectionSPF 50 · 3 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.
Anti-agingSide benefit the brand mentions · Centella asiatica extractWorks well
“Anti-pollution Skin Shield Artemisia Cailaris Extract protects the skin from fine dust and other external stressors.”
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: centella asiatica extract.
Evens skin toneNot advertised by the brand · No ingredient credited for this claimWorks 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-oxidationNot advertised by the brand · Centella asiatica extractMay help
This product contains antioxidants (centella asiatica extract) that might be able to help neutralize free radicals in skin to lessen the damage it gets from the UV light (sun). There is not enough evidence to confirm their effectiveness in skin though.
MoisturizingSide benefit the brand mentions · Cyclomethicone, Isododecane + 13 moreWorks
“COSRX Shield Fit All Green Comfort Sun SPF50 is a sunscreen that creates a safe shield over your skin barrier, protecting it from UV damage.”
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:
cyclomethicone, glycerin.
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: cyclomethicone, isododecane.
