Hi, Thanks for posting in HCM. I understand your concern. Using lemonade is not advisable for the condition you have described. As lemonade contains ascorbic acid, it might cause adverse reaction on skin and cause skin burns and worsen your scars. Hence, it would be better avoided. Instead you can use cleansing solution of which its pH is balanced to neutral. Kinly follow the medications as advised by your dermatologist. Hope the information provided would be helpful. All the best.
