What is acne?
Acne (acne vulgaris) is a chronic condition of the sebaceous follicles. Excess sebum, keratin and the bacterium Cutibacterium acnes lead to comedones, papules and pustules.
What types of acne are there?
Comedonal acne – blackheads and whiteheads. Papular acne – hard, red bumps. Pustular acne – filled with pus. Cystic acne – deep, painful, leaves scars.
How do you care for acne-prone skin?
Gentle cleansing twice a day. Salicylic acid clears the pores. Niacinamide regulates sebum and soothes. Retinol normalizes keratinization. SPF 50+ prevents dark spots.
When should you see a dermatologist?
For cystic, widespread or scarring acne. A dermatologist can prescribe retinoids, antibiotics or hormonal products – skincare then plays a supporting role.
