- Condition GuideClosed comedonesThe focus of treating closed comedones is topical medication to reduce pore blockage of closed and open comedones, along with low-irritation skin care. Topical retinoids, benzoyl peroxide, or azelaic acid are selected based on skin condition and possibility of pregnancy; since these typically take several weeks, initial irritation and the number of new acne lesions are recorded. Do not squeeze by hand or repeatedly use antibiotics alone.→
- Condition GuideAcneAcne begins with follicular keratinization, where dead skin cells at the opening of the follicle tangle with sebum and block it, and the acne-causing bacteria naturally living on the skin contribute to inflammation. Hormonal changes such as puberty or pregnancy, family history, and certain medications can increase the risk, and skin or hair products that block pores may also be related to acne. Diet or stress can be aggravating factors for some people, but a single food or cleansing habit cannot be concluded as the sole cause of all acne.→
- Medical Evaluation GuideWhat should I check first when acne suddenly increases?Do not view a sudden increase in acne as all being the same type; categorize them into closed comedones, red pimples, pus-filled acne, and deep, painful nodules. Also note the date you started new medications or cosmetics, and changes in menstruation, sleep, or stress. If deep nodules increase rapidly or if the face swells and develops a fever, you must seek medical evaluation rather than just recording symptoms and waiting.→
