New favorite serum
This is an amazing serum that has now replaced my former vitamin c. This absorbs so quickly into the skin, and I can wear it under makeup without it pilling. I don’t notice it leave any type of tint either which is a plus. I have extremely sensitive skin and have been able to use this with zero issue.
