The peels such as TCA should be only done by professionals. At home use products might not have the same standards and controls i.e., it might say 15% but in reality was 25%.
Also the right way to do a peel is not something you can achieve at home.
If you do not want to see a professional for acne related chemical peel, you should instead try this;
Wash the hands with antibiotic soap for at least 30 seconds, not to touch the face without washing hands or using a hand sanitizer, changing the pillow case regularly (at least twice a week) and using the following skin care from a skin care line called PCA (Physicians Choice of Arizona). There are four steps and you should do it in the monring and at bedtime.
1. Clean the face with 5% BPO cleanser
2. Use Nutrient Toner
3. Apply Acne Gel
4. Apply Clearskin moisturizer
If you follow this religiously , your acne will certainly get under control.
Now for the acne scarring (mild);
Get Sculptra injections by someone who does it regularly. Other fillers such as Juvederm, Restylane or Radiesse will help as well but they will not last as long as Sculptra.
Goodluck and regards
