Hello, Opexa doses not help reduce chickenpox scars. Its only help is hypertrophic scars. There are various treatments for acne scars which include creams, chemical peels, microdermaabrasion, microneedling, radiofrequency, surgery, fat fill laser etc. Creams work only for superficial pigmentation not for scars. Ideal in chicken pox scar are subcision and fat fill. Contact a dermatologist.
