Early shine, enlarged pores, persistent imperfections… These characteristic signs of oily skin often originate from an imbalance in skin pH. When pH rises above 6, the skin’s surface environment becomes more alkaline than it should be, impairing the barrier function and encouraging the proliferation of microorganisms—especially bacteria involved in acne breakouts. This imbalance also stimulates excessive sebum production, worsening the vicious cycle of shine and irregularities.
The science behind oily skin
Normally, a slightly acidic pH (around 5.5) slows bacterial growth and regulates sebum production. But when pH becomes more alkaline, the skin loses this natural regulation: the imbalance stimulates the sebaceous glands, which then produce excess sebum. This excess, combined with dead skin cells, clogs pores and creates the perfect environment for imperfections such as pimples and blackheads.
The consequences of an overly alkaline pH
Beyond shine and imperfections, a high pH weakens the skin barrier: the skin reacts more strongly to aggressions, and the inflammatory cycle sets in.
