Hi. Greetings. The small bumps may be white heads / or due to sweating. The following would help you : 1. Daily use of sunscreen in day time of SPF 30 applied half hour before sun exposure 2. Daily bed time use of retinol based cream at bed time - under prescription. 3. Exfoliating agents prescribed by dermatologist for reducing tan and improving your natural skin colour and reducing acne/spots. 4. Evaluation by dermatologist and micro derm abrasion if needed - this may indeed help. 5. Kindly read my blog on daily skin care on Practo health feed. 6. Daily fitness work out and loads of fruits and veggies will help loads in improving your skin. Hope this helps. Warm regards. Dr Govind S Mittal, Excel care hospital, Bangalore.
