Beautiful Girl Face. Perfect skin

Use a gentle cleanser that contains salicylic acid, benzoyl peroxide, or glycolic acid to remove dirt, oil, and makeup from your skin. These ingredients can help unclog your pores and prevent acne-causing bacteria from growing. Avoid scrubbing or rubbing your skin too hard, as this can irritate your skin and worsen your acne. You should cleanse your skin twice a day, in the morning and at night.

A Good Skincare Routine for Acne-prone

Apply a toner that is alcohol-free and suitable for your skin type. A toner can help balance your skin’s pH level, remove any residue left by your cleanser, and prepare your skin for the next steps. Some toners may also contain ingredients that can help soothe, hydrate, or exfoliate your skin. You can use a cotton pad or your fingers to apply the toner to your face, avoiding the eye area.

Acne-prone skin is skin that is more likely to develop breakouts, which can be caused by various factors such as excess oil, clogged pores, bacteria, inflammation, or hormones.
