Skin Purging
Skin purging is a temporary flare of breakouts that can occur after starting an active ingredient that speeds up skin cell turnover, such as a retinoid or a chemical exfoliant like an alpha or beta hydroxy acid. As turnover accelerates, microcomedones that were already forming beneath the surface rise and come to a head sooner than they otherwise would, producing a cluster of blemishes early in treatment.
The distinguishing feature of purging is that it appears mainly in areas where breakouts usually occur and clears faster than a normal blemish would. It is generally expected to settle within a few weeks to roughly a skin-cycle, after which the skin often looks clearer. By contrast, new bumps in areas that do not normally break out, or that persist for many weeks, more likely point to irritation or a reaction to the product rather than purging.
Because purging is driven by turnover-accelerating actives, introducing such products gradually and at lower frequency can moderate it. Maintaining barrier support, gentle cleansing, moisturising, and daily sun protection helps the skin tolerate the adjustment. If breakouts are severe, painful, keep worsening, or last well beyond the expected window, it is sensible to pause and seek advice from a dermatologist rather than assume the process will resolve on its own.
