Let me share a personal experience with you. 

I  am to struggle with acne-prone skin last 4 year like mild acne, pustules, nodule, inflamed bumps closed comedones and blackheads,  and couldn't seem to find a solution that worked for me .I even tried isotretinoin but quickly left it because of its horrible side effects: severe muscle pain, fatigue, and depression. I  tried many oral medicines and topical treatments But then, I started using a  AHA and BHA serum and noticed a significant improvement in my skin's texture and clarity.

The AHA (alpha-hydroxy acid) helped to exfoliate and brighten my skin, while the BHA (beta-hydroxy acid) helped to unclog my pores and reduce inflammation. Since then, I've been a huge advocate for incorporating these ingredients into a skincare routine.

But what exactly do AHA and BHA do for the skin? AHA helps to exfoliate the surface layer of the skin, which can help to reduce the appearance of fine lines and wrinkles, as well as improve skin texture and dark skin tone.

BHA, on the other hand, works to exfoliate inside the pores, helping to clear out excess oil and debris that can lead to acne and other skin issues. Together, these ingredients can help to improve the overall my  appearance and health of my  skin. i Just be sure to start with a low concentration like 10%  AHA & 2%  BHA and gradually increase as your skin becomes more accustomed to the products.

Azelaic acid is one amazing  exfoliation solution in skincare industry spically treated hypergimentation and dark spot use azelaic acid  add in my skincare routine
