SOS SERUM SKINCARE SOS H20 Day Serum — SOS SERUM SKINCARE
Works for
Sun protectionSPF 30 · 4 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-agingHyaluronic acidWorks well
“Anti-ageing ingredients that have been shown to reduce wrinkles, improve skin firmness, tone and significantly improve skin hydration.”
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.
Evens skin toneNo ingredient credited for this claimWorks well
“Anti-ageing ingredients that have been shown to reduce wrinkles, improve skin firmness, tone and significantly improve skin hydration.”
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).
MoisturizingSide benefit the brand mentions · Vitis vinifera seed oil, Glycerin + 4 moreWorks
“Low molecular weight hyaluronic acid locks in essential moisture for smooth, soft, healthy-looking skin.”
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, glyceryl glucoside.
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, vitis vinifera seed oil.
