Retinol is one of the most scientifically proven ingredients in skincare, delivering powerful benefits for ageing, texture, acne, and overall skin health—but its effectiveness depends heavily on how it’s used. Because retinol works through a precise conversion process within the skin, combining it with incompatible ingredients or incorrect layering can reduce results and trigger irritation. Understanding the science behind retinol interactions allows you to avoid common pitfalls, pair it with supportive ingredients, and build routines that maximise benefits while protecting the skin barrier. With the right knowledge, retinol becomes not an intimidating active, but a transformative tool for long-term skin health.
