Clogged pores (open or closed comedones) form when a mixture of sebum and dead skin cells (keratin) accumulates at the opening of the hair follicle and blocks it. When exposed to air, the sebum-keratin mixture oxidizes and turns black—this is a blackhead (open comedone). The keratin plug mechanically stretches the walls of the follicle, making the pore visible and enlarged. Aggravating factors include hyperseborrhea, follicular retention, and comedogenic cosmetics. Regularly unclogging pores—using chemical actives (BHA, AHA) or gentle physical techniques (exfoliation, Konjac sponge)—prevents buildup and helps prevent visible pore enlargement.
Cleansing is the fundamental step in preventing and treating clogged pores. Garancia’s Pschitt Magique Facial Foam (100 ml) emulsifies excess sebum and surface impurities without compromising the skin barrier. Caudalie Vinoperfect Radiance Micro-Peeling Foam combines cleansing and gentle exfoliation in one step—its micro-peeling foam dissolves dead skin cells on the surface and prepares the pores to absorb the active ingredients that follow. The Jonzac Konjac Sponge is an ultra-gentle physical exfoliating tool (made from natural plant fibers)—use it once a day on a wet face to remove impurities without irritation. Niacinamide (vitamin B3, 4–5%) reduces sebum production by 50–60% in 4 weeks—less sebum means fewer clogged pores.
Adsorbent masks are the most effective treatments for deeply unclogging pores. Greenclay (smectite, montmorillonite) adsorbs sebum, impurities, and dead skin cells deep within the pores. Jonzac Gentle Exfoliating Gel (75 ml) and Caudalie Deep-Cleansing Exfoliating Cream (75 ml) combine the adsorbing action of clay with gentle mechanical exfoliation. Activated charcoal (activated vegetable charcoal) is an effective addition—its adsorbent surface area, even greater than that of clay, traps the fatty molecules of oxidized sebum. These masks should be used 1 to 2 times a week, applied in a thin layer for 10 to 15 minutes.
Chemical exfoliants are the most effective active ingredients in the long term for keeping pores clear.Salicylic acid (BHA, fat-soluble) is the first-line active ingredient: its fat-solubility allows it to penetrate sebum-filled pores and dissolve the keratin-sebum plug from the inside. Caudalie Vinoperfect Glycolic Essence (100ml, glycolic acid AHA + resveratrol) is a daily essence—its glycolic acid breaks down the bonds between dead skin cells and helps remove them. The Uriage Gentle Facial Exfoliating Gel (50 ml) and the Caudalie Gentle Exfoliating Cream (75 ml) combine chemical active ingredients with microscopic exfoliating particles.The complexion’s radiance visibly improves after 4 to 6 weeks of a regular exfoliating routine.
Pore size is genetically determined—it is not possible to structurally close an open pore. However, a deep-cleansed, clean pore free of sebum and keratin buildup appears much smaller to the eye. The “shrunken pores” effect observed after a deep-cleansing treatment is therefore real but temporary—it is maintained by a consistent routine. The active ingredients that have a lasting effect on the appearance of pores are: niacinamide (reduces sebum production), salicylic acid (keeps pores unclogged), and retinoids (which normalize keratinocyte differentiation and reduce follicular retention). Garancia’s Éclair de Lune L’Absolu Double Serum Anti-Dark Spots combines depigmenting and brightening active ingredients to simultaneously improve skin texture and complexion after unclogging the pores.
