Do a patch test for serum to check for an allergic reaction.
Rub 1-2 drops of the product onto a small patch of your inner wrist. Since the skin is sensitive here, you’re more likely to notice a reaction to the serum. Wait 24 hours to see if your skin is irritated or breaks out in a rash. If it doesn’t, you can use the product on your face or skin.
