How to Start Using Retinol the Right Way

Tap each step to follow along in order.

  1. Start with a low concentration

    If you are new to retinol, starting with a low-concentration product, around 0.01-0.03%, and watching how your skin reacts is a reliable way to reduce irritation.

  2. Start at 1-2 times a week and build up slowly

    It is generally recommended to begin with just one or two nighttime applications a week, then gradually increase frequency once your skin adjusts to the ingredient, a process often called retinization.

  3. Use it only at night

    Retinol breaks down easily in sunlight and can make skin more sensitive to UV exposure during use, so it belongs strictly in an evening routine.

  4. Always wear sunscreen the next morning

    Skin tends to be more sun-sensitive the day after using retinol, so applying sunscreen carefully and generously the following morning matters more than usual.

  5. Increase your moisturizing routine

    Dryness, redness, and mild flaking are common early on, so pairing retinol with a solid moisturizer helps keep the adjustment period more comfortable.

  6. Avoid it during pregnancy or breastfeeding

    If you are pregnant or breastfeeding, it is safer to avoid retinol and other retinoid-family ingredients and consider an alternative active instead.

  7. See a dermatologist if irritation is severe

    If you experience persistent strong irritation, redness, or a burning sensation, stop using it and consult a dermatologist rather than pushing through.

What retinol actually does, and why beginners should go slow

Retinol speeds up skin cell turnover, which is why it is widely used for fine lines and acne-related concerns, but that same mechanism is also what causes early irritation for many new users. This is general skincare information, not medical advice -- if irritation is severe or persistent, a dermatologist can give guidance specific to your skin.

Purging vs. irritation: telling the difference

Some initial dryness, flaking, or mild redness during the first few weeks is a normal part of skin adjusting to retinol and usually eases as frequency is managed carefully. Strong burning, widespread redness, or reactions that keep getting worse rather than settling down are signs to scale back or stop rather than something to simply wait out.

Frequently Asked Questions

Is flaking or dryness in the beginning normal?

Yes, mild dryness or flaking is a common part of skin adjusting to retinol early on, and it typically improves as your skin builds tolerance and you manage frequency carefully.

Can I use retinol together with a vitamin C serum?

Using both in the same application can increase irritation, so it is generally recommended to split them by time of day -- vitamin C in the morning and retinol at night.
