Scrub granules or fruit acids – which is gentler on the skin barrier? We compare physical and chemical exfoliation based on current research and show which method suits which skin type.

AHA fruit acids such as glycolic and lactic acid are considered gentle exfoliating ingredients for home use. We take a critical look at how they work, concentration limits and the risk to the skin barrier – and at what a safe routine looks like.
