How to Start Retinol Without Overdoing It

⚡ Quick answer: A gentle, step-by-step approach to introducing retinol or retinoids into your routine while minimizing irritation.

Retinoids (including retinol) are among the most studied skincare ingredients, but they can cause dryness, flaking, and irritation if introduced too quickly. Starting low and slow is the standard advice.

Start Low and Infrequent

Begin with a lower-strength product and use it only a couple of nights per week. This gives your skin time to adjust. Many people experience an initial adjustment period with dryness or flaking; building up frequency gradually helps reduce this.

Buffer and Moisturize

Apply retinoids at night to a dry face, and follow with moisturizer; some people apply moisturizer before and after (the 'sandwich' method) to buffer the effect. Use a pea-sized amount for the whole face, since more does not mean better results and increases irritation risk.

Protect and Pair Carefully

Retinoids can increase sun sensitivity, so daily sunscreen is essential. Avoid layering them on the same night as strong exfoliating acids when you are starting out, to limit irritation. Patch-test first, and if you are pregnant or breastfeeding, consult a healthcare professional, since some retinoids are advised against during pregnancy.
