I purchased the 18 applications serum and used one full one on wrinkles every other day. It was too harsh for my skin gave me irritation and bumps. Called customer service to see if they could recommend anything to soothe the irritation , not much help but you would think after spending $50 on their product they would offer to send you something to ease the irritation. I don’t recommend this product if you have sensitive skin!
