That’s why my gentle, yet effective retinol serums have a yellow tint! What makes my Retinol Reform unique is that it’s formulated with a 2.2% encapsulated retinol which quickly penetrates deeply into the skin while slowly releasing the active ingredient instead of all at once to minimize any irritation.
