Cleaning pores is fundamentally a process of breaking down the lipophilic (oil-soluble) plug formed by excess sebum, dead corneocytes, and environmental debris. The most effective evidence-based method involves the use of Beta-Hydroxy Acids (BHAs), specifically salicylic acid. Unlike Alpha-Hydroxy Acids which are water-soluble, salicylic acid is oil-soluble, allowing it to penetrate the lipid-rich environment of the sebaceous follicle to desquamate the internal lining and dissolve the 'glue' holding debris together [1]. This process, known as chemical exfoliation, is superior to physical scrubbing, which often causes micro-tears and can trigger compensatory sebum production.
To optimise the cleaning process, a double-cleansing technique is recommended, starting with a lipid-based oil cleanser or balm to emulsify surface sebum and SPF, followed by a surfactant-based water cleanser to remove remaining residues [2]. This ensures the pore opening is clear for active ingredients to work efficiently. For persistent congestion, incorporating a clay mask containing kaolin or bentonite can offer temporary relief by adsorbing excess surface oils and drawing out impurities through capillary action [3]. Consistency is more critical than intensity; maintaining a regular keratolytic routine prevents the accumulation that leads to comedones.
From a physiological perspective, the 'pore' is the opening of the pilosebaceous unit, comprising a hair follicle and its associated sebaceous gland. In healthy skin, sebum flows freely to the surface to maintain the acid mantle and barrier function; however, hyperkeratinisation—the failure of skin cells to shed correctly—can lead to follicular occlusion [1]. When these cells mix with oxidised sebum, they form a 'plug' or microcomedone. Scientifically, you cannot 'open' or 'close' pores because they lack skeletal muscle; however, you can influence their appearance and cleanliness by managing the rate of keratinisation and follicular oil volume [4].
Clinical studies indicate that chronic pore congestion is often exacerbated by environmental pollutants and high-glycemic diets which can upregulate IGF-1 signalling, leading to increased sebum production [5]. By using biomimetic ingredients and pH-optimised formulations, we can effectively manage the follicular environment to minimise the visible diameter of the pore and maintain a clear pathway for sebum excretion.
For those looking to integrate these clarifying benefits into their daily ritual, our Surface Purify cleanser was formulated with salicylic acid to help gently dissolve internal congestion and minimise the appearance of pores. This targeted approach works to refine the skin's texture without stripping essential moisture, particularly when followed by a calming layer of Balance Biome Crème to support a resilient and healthy microbiome.
FAQ
Does steam help in cleaning pores?
While steam does not 'open' pores (as they lack muscles), it can soften the sebum and keratinaceous debris trapped within the follicle. This thermal effect increases the elasticity of the skin tissue, making the subsequent extraction or chemical cleansing more effective [3]. However, excessive heat can cause vasodilation and exacerbate conditions like rosacea, so it should be used at a moderate temperature [4].
Can you actually shrink pore size?
Genetics and age-related collagen loss primarily determine pore size. However, clinical evidence suggests that topical retinoids can improve the appearance of pore size by increasing cell turnover and supporting the dermal matrix, preventing the follicular walls from sagging [2]. Removing the oxidised 'blackhead' at the surface also reduces the visual contrast, making pores appear smaller to the naked eye [5].
Is oil cleansing safe for oily or acne-prone skin?
Yes, oil cleansing is highly effective for oily skin based on the principle of 'like dissolves like.' High-quality cleansers containing linoleic-rich plant oils or esters can emulsify hardened sebum better than harsh surfactants alone [2]. This prevents the 'rebound effect' where stripping the skin leads to increased oil production to compensate for a compromised skin barrier [1].
