What is the 3 minute moisturizer rule?
The 3-minute moisturiser rule is a guideline that suggests waiting about 3 minutes after applying moisturiser before applying sunscreen or other products. This short wait allows the moisturiser to partially absorb into the skin, so subsequent products can sit and function properly rather than mixing together on the surface.
The guideline is more a practical suggestion than a strict dermatological requirement. The goal is simply to ensure each product has a moment to settle before layering the next one. For most moisturisers, absorption begins within the first minute. A brief wait helps prevent products from pilling, which is the annoying balling up of product that can happen when too many layers are applied too quickly. In a morning routine, applying moisturiser while you do other things like drink your coffee gives it adequate time before you reach for your sunscreen.
