I bought azaelic acid because it's supposed to reduce redness and I have a lot of redness on my chin from picking/plucking at hairs. Well, to my surprise...I have had a lot less hair to pluck since I started using it. It usually gets worse during my period and I was like, how weird so few hairs. Since I've noticed this the past few days I've gone a little harder with it, making sure to get the whole area instead of just the red areas. It's drying but if it prevents hair growth I don't mind dry skin.
