If you’ve just started tretinoin and your skin has turned into a flaky, dry mess within the first few weeks, you’re not doing anything wrong — you’re experiencing one of the most common and well-documented side effects of retinoid use. Here’s why it happens and what dermatology sources actually recommend for managing it.
Why tretinoin causes flaking in the first place
Tretinoin is a retinoid, meaning it speeds up skin cell turnover and pushes newer cells to the surface faster than usual. In the first several weeks of use, this accelerated turnover commonly causes dryness, peeling, and visible flaking as the outer layer of skin adjusts — a period often referred to informally as “retinization” or the “purge” phase. According to the American Academy of Dermatology, dryness, redness, and peeling are expected early side effects for most people starting a retinoid, and they typically ease as the skin builds tolerance over several weeks to a couple of months.
What tends to help, according to dermatology guidance
A few strategies are consistently recommended across dermatology sources for managing retinoid-related flaking:
Start slow and space out applications. Many dermatologists recommend beginning with tretinoin every third night (rather than nightly) and gradually increasing frequency as tolerance builds, which is consistent with the gradual approach described by the AAD’s retinoid guide.
Moisturize generously, and consider buffering. Applying a bland, fragrance-free moisturizer before or after tretinoin (sometimes called the “sandwich method” — moisturizer, then tretinoin, then moisturizer again) can reduce irritation without necessarily reducing effectiveness, per general dermatology practice guidance. The AAD’s moisturizing guidance emphasizes using a gentle, non-comedogenic moisturizer as part of any retinoid routine.
Skip the harsh exfoliants while your skin adjusts. Physical scrubs, high-strength acids, and other actives can compound irritation when combined with a retinoid, especially early on. Cleveland Clinic’s overview of retinoid use notes that pairing retinoids with other potentially irritating actives should generally be introduced cautiously and one at a time.
Don’t pick or scrub at flaking skin. It’s tempting, but manually removing flakes can increase irritation and slow the barrier’s recovery. Gently patting on moisturizer tends to work better than rubbing.
Sunscreen is non-negotiable. Retinoids can increase sun sensitivity, so daily broad-spectrum SPF is considered essential during treatment, per the AAD.
When flaking is a sign to slow down
Mild peeling is expected, but significant redness, burning, swelling, or skin that feels raw is a sign the concentration or frequency may be too aggressive for where your skin currently is. In that case, dermatology guidance generally supports reducing frequency, allowing more recovery time between applications, or speaking with a dermatologist about adjusting the regimen — rather than pushing through discomfort.
The bottom line
Flaking in the first few weeks of tretinoin is common and, for most people, temporary as the skin adjusts. Going slower, moisturizing consistently, avoiding other harsh actives in the meantime, and protecting your skin with sunscreen are the strategies most consistently backed by dermatology sources. If irritation feels excessive or doesn’t improve, that’s a good reason to check in with a dermatologist rather than tough it out.
