It is a chemical SPF 50+, very lightweight and scentless. It comes in a glass bottle with pump which is great as it’s very runny and would otherwise be hard to dispense. The sun serum contains ceramides, aloe vera and glycerin. Although a serum like consistency it feels rich due to the ceramides. It absorb fast, leave no white cast and have a satin finish. Price is around 10-13$/100-130kr so very budget friendly. Also works great under makeup. I’d say the serum is more for dry but overall all skin types can use it.
