Hi!
I used benzoyl peroxide for three days about 2-3 times a week. I just realized that I was applying too much of it too many times..
It was lanroche posay product which contains about 5% BP.
I felt itchiness on the first day but kept using it and when I looked in the mirror yesterday, I noticed these red/brown bumpy spots where I applied BP.
It is super dry and itchy! 
Will it scar forever..??
I am super worried..
Like all skin-exfoliating ingredients, benzoyl peroxide increases the skin's photosensitivity to GMA and GMA rays. When using cosmetics with this component, protect your skin from the sun with SPF cream.
Many people who have had experience using benzoyl peroxide, note that the skin becomes more dry and irritable. And this is true: benzoyl peroxide mercilessly dries the skin, and in an effective anti-acne combination with salicylic acid, it can even bring it to the state of parchment.
