This serum is very soothing & refreshing almost immediately upon contact. It's also very gentle and doesn't give me any sort of irritation even when my skin is feeling very sensitive. I use this at night and always notice a significant reduction in redness by morning. Blemishes are also much more calmed. I love using it at the first signs of acne to keep things calm and start the healing process. Another great product from Purito!
Oddly enough, before I noticed any sebum regulation, my skin actually got oilier before eventually fully adjusting and evening out, which I thought was interesting. Also, dry skin types probably won't benefit from this as much.
