Do not use anything other than what your dermatologist has prescribed. The skin is more sensitive after procedures like peels. Although it is unlikely that you will react to sandal paste after a peel why take the chance. Discuss what you can and can't do before the next session with your dermatologist. The general instructions I give my patients after a peel is to use certain medicines to quickly regrow the peeled skin(for the 1st 5 days) with sunscreen. Warm regards. Dr. Rajdeep Mysore.
