This is MYTREX gel. Moisturizing serum MYTREX Platinum Nano Lift Gel 100g This was a gift, but I mistakenly thought it was a cosmetic and used it once. It seems to be used with a dedicated device, so I am selling it because I won't be using it anymore. About 90% of the product remains. Please understand that this is a used item before purchasing. No price reduction, please.
