First, acne comes in two types: open and closed comedones, commonly known as blackheads and whiteheads. Open comedones are pores stretched into tiny holes where contents can be squeezed out. Closed comedones appear as small bumps on the skin, often barely visible from a distance. They aren't red, swollen, painful, or itchy. You must touch them to feel them, though some may notice uneven skin texture under side lighting.
Second, closed comedones are a type of closed acne. Because the pores are closed, these comedones haven't yet surfaced and oxidized into blackheads. Closed comedones typically take about five months to reach their peak growth. Their development involves two possible changes: first, rupture, leading to inflammatory acne; second, transformation into open comedones.
Why Closed Comedones Form: The Need for Regular Skin Renewal
Everyone desires skin as smooth as silk. Yet suddenly, tiny bumps appear all over the face—not red, not painful, and refusing to fade. How do these closed comedones emerge? Why does perfectly healthy skin develop them?
Dryness
When skin lacks sufficient moisture, its metabolism slows down. This reduces the production of new skin cells and prevents old, dead skin cells from shedding normally, causing them to accumulate on the skin's surface.Additionally, UV rays accelerate skin dryness, making them a primary culprit behind thickened keratin.
Friction
Many unintentional physical frictions can also cause keratin buildup and thickening. Examples include washing your face without lathering and directly rubbing the skin with fingers, or vigorously rubbing your face with a towel after cleansing. Such friction triggers the skin's self-defense mechanism, leading to thickened keratin.
Vitamin Deficiency
Vitamins are essential for skin health, particularly vitamins B and A, which are closely linked to skin metabolism. Insufficient levels of these vitamins slow down the growth of new cells. Without mature new cells, old, dead keratin remains trapped on the skin's surface.
Closed Comedones: Annoying but Manageable Solutions
Safe Makeup Removal: Eliminate the Root Cause of Closed Comedones
Many reports of closed comedones stem from makeup removal. Incomplete emulsification of cleansing oils or mineral oil residue trapped in pores can contribute to excess oil buildup. When this oil mixes with skin's natural dead cells, it forms dreaded closed comedones.Remember: Makeup removal is crucial—don't let the first step of your skincare routine fail you.
Gentle Cleansing: Protect Your Natural Oils
Proper cleansing and gentle exfoliation can reduce closed comedones. Maintain a balance in cleansing to avoid damaging the skin, which can trigger increased oil production and more closed comedones.Therefore, opt for gentle cleansers that leave skin clean without tightness. Avoid cleansers that create a false slippery sensation after use.
Skin Hydration: Balancing Oil and Moisture
Dry weather often triggers closed comedones. The key during this time is skin hydration. By maintaining a balanced oil-moisture ratio while cleansing, you naturally prevent clogged pores and closed comedones. Opt for hydrating cleansers during dry seasons.
Choose Salicylic Acid Skincare: Boosts Metabolism
Salicylic acid excels at exfoliation while also promoting skin metabolism. It shrinks pores, clears blackheads and whiteheads, effectively reduces fine lines and wrinkles, and helps restore skin radiance. For areas with closed comedones, apply a salicylic acid serum as a compress or use it morning and night. After a period, the closed comedones will disappear.
Apply Vitamin A Cream: Renew the Stratum Corneum and Suppress Inflammation
If the "closed comedones" are severe and show signs of inflammation, it's best to consult a professional dermatologist at a hospital.Typically, doctors treat acne-related issues with vitamin A-based medications to renew the stratum corneum and suppress inflammation. However, vitamin A derivatives like tretinoin are potent inorganic acids with strong irritating properties. They weaken the skin barrier's protective function and carry significant side effects, so strict adherence to medical guidance is essential. Self-purchasing and experimentation are not recommended.Closed comedones form when dead skin cells clog pores, preventing sebum from draining and creating raised bumps on the skin's surface. To prevent their formation, avoid pore blockage by exfoliating dead skin cells. The skincare tips mentioned earlier can serve as helpful references!
