Doctor: Hello and Welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.  It could be because of decrease collagen content in skin. Take Vitamin C supplements daily. Avoid scratching/rubbing the skin. If you have itching, take Levocetirizine/Cetirizine tablets. In case of worsening of rash or appearance of new lesions, do consult your Dermatologist.  Hope I have answered your query. Let me know if I can assist you further.  Regards, Dr. Siva Subramanian
