Blackheads, or open pimples, are a type of acne lesion that can be improved through life management, medication, and physical therapy.
1. Life management: avoid oily and sugary foods, get enough sleep, use mild cleansing and moisturizing products, and avoid prolonged exposure to ultraviolet rays.
2. Medication: Adapalene gel can be used externally, which has the effect of regulating follicle keratinization and anti-inflammation, and fruit acid and salicylic acid can also be used externally, which has the effect of dissolving lipids and improving follicle keratinization.
3. Physical therapy: red and blue light therapy and photodynamic therapy can improve acne to a certain extent.
The above medications should be used under the guidance of a doctor. 12-year-old children with open acne should go to a regular hospital for standardized treatment.
