How to use retinol, step by step

Use retinol at night, on clean dry skin, as a pea-sized amount for the whole face, starting two or three nights a week and building up slowly. Follow with moisturizer, wear sunscreen every morning, and give it a few months. Most problems with retinol come from doing too much, too soon.

The short answer

To use retinol, cleanse at night, let your skin dry fully, then smooth a pea-sized amount over your whole face, avoiding the eyes, nostrils and mouth corners. Finish with a plain moisturizer. Start every second or third night for the first couple of weeks and add nights only if your skin stays comfortable. Wear broad-spectrum sunscreen of SPF 30 or higher every morning, and expect several weeks before you see change and several months for fine lines.

Key takeaways
  • Retinol is a night-only step: pea-sized amount, dry skin, then moisturizer.
  • Start with the lowest strength you can find, every other night or less, and build up over weeks.
  • Daily sunscreen is not optional, and retinoids should be avoided during pregnancy.

Before you start

What retinol is, and who it suits

Retinol is a form of vitamin A sold over the counter in serums, creams and gels. Your skin converts it into retinoic acid, the active form that speeds up skin-cell turnover and supports collagen. That is why it can help with mild acne, uneven tone and texture, and fine lines. Our retinol ingredient guide covers the evidence in depth; if you are still deciding, read should you use retinol? first.

The AAD says retinoids are a good fit for mild acne, mild pigment irregularities and mild fine lines. It suggests people with skin allergies or very dry skin may not be good candidates, and that heavy redness or inflammation usually needs different treatment, such as for rosacea.

Good time to start

  • Your skin is calm, not sunburned or freshly waxed.
  • You can commit to daily sunscreen.
  • You have a simple routine you can keep steady for a few months.
  • You picked a low-strength product to begin.

Wait or ask first

  • You are pregnant, trying to conceive or breastfeeding.
  • Your barrier is damaged, stinging or peeling.
  • You have eczema or rosacea flaring on your face.
  • You already use a prescription retinoid.

Patch test before your first full-face use. Cleveland Clinic suggests a small test area and waiting a couple of days to check for significant redness or itching. Our patch-testing guide shows where and how.

Step by step

How to apply retinol correctly

  1. Cleanse gently in the evening

    Use a mild, non-scrubbing cleanser and pat dry. The AAD advises using retinoids only at night, partly because they make skin more sun-sensitive.

  2. Let your skin dry fully

    Damp skin can take up more product and sting more. Cleveland Clinic suggests waiting about 30 minutes after washing, which is a useful tip if you are sensitive.

  3. Use a pea-sized amount for the whole face

    Dot it on forehead, cheeks and chin, then spread a thin layer. Keep clear of the eyelids, nostril creases and mouth corners, where skin irritates easily.

  4. Follow with moisturizer

    A plain, fragrance-free, non-comedogenic moisturizer helps reduce dryness. Whether it goes before or after retinol depends on your skin; see retinol before or after moisturizer.

  5. Wear sunscreen every morning

    Apply a broad-spectrum SPF 30 or higher daily, even when cloudy. Use enough: our sunscreen amount guide explains the two-finger rule.

Buffering (the “sandwich” method): if retinol stings, apply a thin layer of moisturizer first, then retinol, then more moisturizer. It cushions irritation and is a sensible way to start; some people move to applying it directly once their skin adjusts.

Start schedule

How often should you use retinol when starting?

PeriodHow oftenWhat to watch for
Weeks 1 to 22 nights a week (for example Monday and Thursday)Mild dryness or tightness is common. Stinging that lasts is a sign to slow down.
Weeks 3 to 4Every third nightFlaking around the nose and mouth; add more moisturizer.
Weeks 5 to 8Every other nightSkin should feel settled. Some breakouts may appear if you are acne-prone.
Week 9 onwardNightly, if comfortableMany people stay at every other night long term, which is fine.
Month 3 to 6Consider a stronger productOnly if your skin has been comfortable for several weeks at your current strength.

This is a cautious version of the approach both the AAD and Cleveland Clinic describe: start every other night or less, then build up gradually. If your skin is sensitive, stretch each stage out. Frequent use is not required for results: in a small 2007 trial in older adults, a 0.4% retinol lotion used up to three times a week improved fine wrinkles over 24 weeks compared with a plain lotion. Whether you ever need to go nightly is covered in can you use retinol every day?, and our beginner retinol routine turns this schedule into a full evening plan.

Combining products

What can you use with retinol, and what should you separate?

IngredientWith retinol?How
Niacinamide, hyaluronic acid, ceramidesUsually fine togetherCleveland Clinic notes hydrating ingredients may help offset irritation. See retinol with niacinamide.
Vitamin CSplit the dayVitamin C in the morning, retinol at night. More in retinol and vitamin C together.
Glycolic or lactic acid (AHAs)AlternateDifferent nights, or acid in the morning. See glycolic acid with retinol.
Salicylic acid (BHA)AlternateBoth can dry skin; use BHA in the morning or on non-retinol nights.
Benzoyl peroxideSeparateUse at different times of day; both can irritate.
Another retinoidNoUse one retinoid product at a time.

A simple evening order is cleanser, retinol, moisturizer. If you also use a serum, the general rule of thinnest to thickest applies; see skincare layering order.

Side effects

Is it normal for retinol to irritate at first, and when should you stop?

Yes, some irritation is expected early on. Cleveland Clinic lists dryness, redness, itching or burning, and peeling or flaking as usually temporary side effects that fade as skin adjusts. The AAD warns that irritation can leave dark marks, especially in darker skin, which is one more reason to go slowly.

Acne-prone skin may break out more for the first weeks, sometimes called purging. Our purging vs breakout comparison explains how to tell the difference.

Normal

Mild dryness or flaking

Use more moisturizer and drop back a night or two each week.

Slow down

Stinging that lasts

Pause for a few nights, then restart at a lower frequency or with buffering.

Stop

Swelling, raw skin or a rash

Stop and let skin recover. If it does not settle, see a doctor.

Reassess

No change after months

Cleveland Clinic suggests talking to a clinician if OTC retinol has not helped after a few months.

If you want a gentler alternative, retinol vs bakuchiol compares the two. If OTC retinol is not enough, retinol vs tretinoin explains what prescription strength adds.

Safety and professional-help boundaries

When to stop retinol and get advice.

  • Do not use retinol or any retinoid while pregnant or trying to conceive; ask your clinician before restarting while breastfeeding. See skincare during pregnancy.
  • Stop and seek care if you get swelling, blistering, hives or a spreading rash.
  • Skip retinol on sunburned, broken, freshly waxed or irritated skin.
  • See a dermatologist before starting if you have moderate or severe acne, acne scars or hormone-linked breakouts.
  • Tell your prescriber if you use prescription acne or eczema treatments before adding an OTC retinol.

Frequently asked questions

Short answers to common questions

How do you use retinol for the first time?

Use a pea-sized amount of a low-strength retinol at night on clean, dry skin, then apply moisturizer. Start two or three nights a week and wear sunscreen every morning.

How much retinol should I use on my face?

A pea-sized amount is enough for the whole face. Using more does not work faster and makes irritation more likely.

Do you put retinol on before or after moisturizer?

Most people apply retinol first and moisturizer after. If your skin is sensitive, a thin layer of moisturizer before and after retinol can reduce irritation.

Should I use retinol every night?

Not at first. Start every second or third night and only move toward nightly use if your skin stays comfortable for several weeks.

Can I use retinol in the morning?

It is best used at night, because the AAD advises night-only use and retinoids make skin more sensitive to the sun. Use sunscreen, not retinol, in the morning.

Can I use retinol around my eyes?

Keep it off the eyelids and away from the inner eye area. If you want to treat crow’s feet, use a product made for the eye area or a very small amount on the outer bone, and stop if it stings.

How long does retinol take to work?

Expect several weeks before skin looks smoother and several months for fine lines and dark spots. Acne can look worse in the first weeks before it improves.

Can I use retinol with vitamin C?

Yes, but at different times of day. Use vitamin C in the morning under sunscreen and retinol at night.

Is retinol safe for sensitive skin?

It can be, if you choose a low strength, use it less often and buffer it with moisturizer. If your skin keeps stinging or turning red, stop and ask a dermatologist.

Can I use retinol while pregnant?

No. Retinoids, including retinol, should be avoided during pregnancy, and you should ask your clinician before using them while breastfeeding.
