Movement of our body can be voluntary and controlled by the skeletal muscles, or it can be involuntary and controlled by smooth muscles. Those are found mostly in your internal organs and aid in things like digestion and even eyesight. Skeletal muscles, on the other hand, are what make up what we see a human body do.
TCA peel is a mid-grade chemical peel that penetrates deeper layers of skin providing deep cleansing and rejuvenation. The main ingredient of the formulation is trichloroacetic acid which is a type of acetic acid as a highly toxic chemical absorbed through the skin with a strong bactericidal and anti-inflammatory effect used as a chemical cauterant.
First of all, a TCA peel should never be applied at home. It doesn't matter how experienced you are with receiving chemical peels, or even if you are trained and licensed to apply them. This is a medical chemical peel and should ONLY be done in a doctor's office. Secondly, 25 seconds for a 35% TCA peel should be sufficient. The skin should frost over almost immediately even if the dermatologist didn't say anything. You should experience the peeling you are looking for, but you need to give it several days to start doing so.
