This category holds a single, purposeful product: the Stabilizing Lotion pH Balance, Physiodermie’s toning step within the Swiss Methode routine. Cleansing, even with a gentle milk formula, can leave skin’s surface pH slightly elevated, and this lotion is formulated to rebalance it before any concentrate or cream is applied. Rebalanced pH matters for how well the skin’s barrier functions and how effectively the products that follow are absorbed.

The Stabilizing Lotion suits nearly every skin type, since pH balancing is a foundational step rather than a formula targeted at one specific concern, and it is meant to be used daily, immediately after cleansing and before a Bioarome concentrate or finishing cream. Skipping this step is one of the more common ways a professional routine underperforms at home, which is why Physiodermie makes it a distinct, non-optional stage rather than folding it into the cleanser. OSC carries the Stabilizing Lotion as part of its authorized Physiodermie assortment.
