For a week post treatment it is better to avoid home remedies, parlour procedures, skin rubbing and manipulation, swimming, excessive sun exposure and harsh scrubs and soaps to avoid irritation of treated area. Apply sunscreen, moisturisers and antibiotic creams as prescribed. When in doubt always clarify with the treating dermatologist. 

Skin creams, hair serums, supplements and proper skin and hair care form the backbone of any treatment. They can give excellent response by themselves.  Aesthetic treatments just offer an alternative option for faster and better outcomes. Except for LASER hair removal for which there is no medical treatment LASERs are not mandatory. 

All dermatologists are experts in taking care of skin issues. But doing aesthetic treatments and LASERs need additional training. There are many training centres where doctors get such training for few days to months after MD degree. But there is also an university accredited degree of one year which includes  formal training and assessment following which a fellowship degree is awarded. Only they can be displayed on their credentials. In Tamil Nadu, Dr. TNMGR university accredited post doctoral fellowship degree (PDF) is awarded to only 2 to4 dermatologists every year. Dr. Shanmuga Priya holds PDF degree in aesthetic dermatology, the only skin specialist in Madurai to have one. When selecting a dermatologist for aesthetic treatments/LASERs make sure they have such training, skill and experience.
