Depending on what kind of chemical peel you choose to undergo, there are some instructions that your doctor may advise you to heed pre-peel. In the week before treatment, you're likely going to be asked to not undergo any other chemical peels, any kind of waxing, electrolysis or laser hair removal procedures or Botox injections. You should also avoid using exfoliating masks or rough, abrasive sponges on your skin. In the three days before your procedure, you'll be asked to not use tretinoin, the acid form of vitamin A that's commonly used in a gel to treat acne or stretch marks, among other things. Other retinoic acid derivative creams and gels are probably also likely to be on the no-use list, which includes Retin-A.
On the day of your treatment, you should arrive with a clean face and no make-up, moisturizers, cologne, perfume or aftershave. Men are advised not the shave their face the day of the appointment. Cleaning your face the day before your treatment with an antiseptic soap is also generally recommended. It should be noted that these are all general instructions. Depending on what kind of peel you're undergoing, you'll receive specific instructions from your health care provider and it's important to follow them explicitly if you want a positive result.
