What is retinol purging and is it normal?

Retinol purging is a temporary skin reaction where increased cell turnover brings underlying congestion to the surface faster than normal, causing breakouts in the first 4–6 weeks. It is a normal part of the adjustment process and typically resolves on its own. True purging only occurs in areas prone to breakouts. If new blemishes appear in unusual locations, it may be a reaction rather than purging.
