It's crucial to shield your skin from sun exposure and inflammation when taking isotroin and getting chemical peels. Eat a well-balanced diet that includes plenty of fruits, vegetables, protein, and water. Steer clear of excessive amounts of alcohol, tobacco, and fatty junk food. Unless your physician recommends it, avoid using abrasive scrubbing or potent skin care products. Although the length of isotretinoin treatment varies from person to person, many people take medication for four to six months, or sometimes longer depending on body weight and the severity of their acne. Since you have previously been taking 20 mg every day for four months, you should only continue under the supervision of your dermatologist with frequent monitoring and follow-up.
