Wear soothing skincare that contains Centella Asiatica,Aloevera and propolis to help soothe redness.Niacinamide can also help to calm redness and help to treat the pimple.
Don't try to pop it, otherwise the scar can take longer time to heal.
Use spot treatment (benzoyl peroxide spot treatment) and pimple patches so that the pimple take less time to heal and to avoid from you touching it.
note that Benzoyl peroxide is drying so wear extra moisturizer on the area you put Benzoyl Peroxide spot treatment.
You can also use some brightening skincare products to help lessen the pimple marks appearance when it's healed.
I hope this help🤗
