Coola Dew Good Illum Serum SPF30
Works for
Sun protectionSPF 30 · 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 toneNo ingredient credited for this claimWorks well
“Perfect to use as a makeup primer, the lightweight serum sits sheer on the skin, brightening the complexion.”
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 · Aloe barbadensis leaf juiceWorks 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.
MoisturizingSide benefit the brand mentions · Glycerin, Lactobacillus ferment + 4 moreWorks
“Enriched with lactobacillus ferment to support the skin barrier and enhance moisture retention, the silky serum provides broad-spectrum UVA and UVB protection, contains antioxidant-rich hydrators, and instantly gives the skin a dewy glow.”
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, lactobacillus ferment.
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: ethylhexyl hydroxystearate, caprylyl glycol.

Product summary
The ingredient list suggests that "Coola - Dew Good Illum Serum SPF30" 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).
This sunscreen should also be hydrating enough to use without an additional moisturizer during the day. Like all broad-spectrum sunscreens, this product has an anti-aging benefit.
