When selecting skincare products to address closed comedones, it is important to focus on the ingredients and efficacy of the products. Recommended types of skincare products include: 1. Products containing salicylic acid: Salicylic acid helps dissolve the stratum corneum and unclog pores, effectively removing closed comedones. However, overuse should be avoided to prevent skin dryness. 2. Products containing vitamin A derivatives: Such as retinol, which can inhibit sebaceous gland secretion and alleviate symptoms of closed comedones. These products should be used under the guidance of a physician. 3. Products containing tea tree oil and niacinamide: Tea tree oil has antibacterial and anti-inflammatory properties, while niacinamide can inhibit sebaceous gland secretion. These ingredients help improve overall skin condition. 4. Mild and moisturizing skincare products: For sensitive skin, it is advisable to choose gentle, non-irritating cleansers and toners with moisturizing properties to maintain the skin's barrier function.
