Which chemical peel type & concentration level do you recommend for this tiny shallow scar, or something else entirely? (Photo)

I’m 19 years old, 4 months ago I got this tiny spot in between my eyebrows and I picked at it, until it bled and ripped. I have applied sudo cream.Then I applied piona bleach to lighten it, which made it shallower. I’m self-conscious about it now. In reality the scar is a light brown/red colour. I was thinking of applying a chemical peel at home. I have heard of many such as glycolic, salicylic, TCA, to smooth out the scar. I’m a first time user and I have sensitive acne prone skin.
