Acne Breakout on Dry Skin. Any issue!

Hi Doctor, I have dry skin (never been oily), my food intake is usually and preferably home prepared meals (although outside food still happens for like 2-3 times a week). I've always had a clear skin wherein a pimple or two might rarely occur but they were usually because of sweat and dirt. Coming to genetics, my parents both have a pretty clear skin and they never faced any issue regarding pimples or acne. For the past year, I've been facing a regular breakouts of multiple pimples all over my face. I had been using normal Himalaya Face Wash all my life but since January '20, I have been using Cipla Saslic DS Foaming Facewash, followed by Peroclin gel (as suggested by my cousin who's a physician practicing in US). This somewhat helped me see some improvement in the initial weeks but it's back to square one and the pimples are in immense amount. Please suggest me some professional measures to get rid of them completely. My concern also consists of many after-marks residues of acne.
