Hello. I recently ordered pure cas: 27-47-9 retinol powder from Canada. Can someone provide instructions on how much retinol by weight I must add to say 50ml of oil? I want to apply retinol solution on my face and palms to reduce aging signs, deeper wrinkles. Any edible oil will work, which is best to use?
How to prepare oil solution with retinol powder for face wrinkles?
