Doctor, thank you so much! Iโm a tourist visiting Korea, and Iโve always been a skincare enthusiast. I use azelaic acid from Australia, so I bought the Azalea cream for comparison. I donโt get acne often, but the scars take forever to fade, so I got the Noscarna cream to try, and the Sevita B gel too since my friend said it helped with preventing hormonal acne on her chin. Thank you so much for the very thorough and clear explanation, as well as the many different subtitles, so international viewers can benefit from your knowledge.
