Hi. Greetings. The following precautions would help you :
1. Daily use of sunscreen in day time of SPF 30 applied half hour before sun exposure. This will prevent photo agreeing and damage.
2. Daily bed time use of moisturiser like cetaphil or emoderm. Reapply during lunch break during day time if u have dry skin. You could try acne moist cream which is special moisturiser for people with acne.
3. Use Anti acne agents prescribed by dermatologist for pimples
4. Salicylic acid based face wash.
5. Kindly read my blog on daily skin care on Practo health feed.
Hope this helps.
Warm regards. Dr Govind S Mittal, excel care hospital, Bangalore.
