Skincare Layering Guide
The general rule for skincare layering is to apply products from thinnest to thickest consistency. Actives like Vitamin C and retinol need wait times to absorb and work at the correct pH. Never combine retinol with AHA/BHA in the same routine, and always finish with SPF in the morning. Consistency matters more than complexity - a simple routine done daily beats an elaborate one done sporadically.
