How to use tretinoin cream: label steps and AAD tips
Quick answer: Apply tretinoin cream once a day at bedtime, or as your prescriber directs, to skin that is clean and fully dry. The Retin-A patient leaflet describes about a half inch or less on the fingertip, which it says should be enough for the whole face. Keep it away from your eyes, mouth and the corners of your nose, and protect treated skin from the sun. The leaflet also recommends a noncomedogenic moisturizer every morning after you wash. Your own prescription label and your dermatologist’s directions always come first.
The steps below come from three sources. They are the Retin-A prescribing information and patient leaflet on DailyMed, the MedlinePlus entry for topical tretinoin, and the American Academy of Dermatology’s acne treatment page. This article gives general information only. It doesn’t replace the directions on your own prescription.
What should you know before your first tretinoin application?
Tretinoin belongs to a class of medicines called retinoids. MedlinePlus says it works by increasing production of new skin cells and unclogging pores, and it comes as a lotion, cream and gel. The American Academy of Dermatology lists tretinoin among the prescription retinoids used to treat acne. A prescription is the starting point, so the directions that matter most are the ones your dermatologist writes for you.
Tell your prescriber about a few things before night one. MedlinePlus asks you to mention eczema, actinic keratoses, skin cancer, or any other skin condition. It also asks you to say so if you’re pregnant, plan to become pregnant, or are breastfeeding, and to call your doctor if you become pregnant while using it. Tell your prescriber about your other medicines and supplements too. The Retin-A prescribing information adds that patients with sunburn should not use the product until fully recovered.
The AAD also asks you to mention a past reaction. If a retinoid irritated your skin before, the AAD says that irritation doesn’t typically mean you have an allergy and that a retinoid may still be an option. Your dermatologist can only plan around that history if you share it.
How do you apply tretinoin cream step by step?
The order below follows the Retin-A leaflet and MedlinePlus. Most of these steps aim to reduce irritation.
- Wash your hands and the affected skin with a mild, bland soap and water, not a medicated or abrasive soap or one that dries the skin, as MedlinePlus directs.
- Pat your skin dry and wait. The Retin-A leaflet says to wait 20 to 30 minutes before applying the medication so the skin is completely dry.
- Squeeze the amount your prescriber advised onto a clean fingertip. The leaflet describes about a half inch or less for the whole face.
- Dab it on your forehead, chin and both cheeks. Then spread it over the affected area and smooth it gently into the skin, as the leaflet describes.
- Keep it out of your eyes, ears, mouth, the corners of your nose and open wounds. MedlinePlus also says not to apply it to sunburned skin or skin affected by eczema.
On the wait, the leaflet says it’s important for the skin to be completely dry to minimize possible irritation, so the full 20 to 30 minutes stays in the routine.
How much tretinoin cream should you use?
The Retin-A leaflet says to squeeze about a half inch or less onto the fingertip and notes that this should be enough for your whole face. It adds that with experience you may find you need slightly more or less, so check with your prescriber. It also says the cream should become invisible almost immediately, and that if it’s still visible you’re using too much.
You’ll often see “pea-size” online. The sources used here don’t use that word, so this article uses the label’s own wording instead. More cream does not give faster results. The leaflet says an excess may irritate your skin and that you can’t make the medication work faster by applying it more than once a day. MedlinePlus separately says to use it exactly as directed, not more or less, and not more often than prescribed.
How often should you use it, and what about the sandwich method?
MedlinePlus and the Retin-A leaflet both describe daily use at bedtime. The Retin-A leaflet adds that a physician may advise starting with every other night, especially if your skin is sensitive. That ramp-up belongs to your prescriber. Don’t build your own schedule from a forum post.
Moisturizer layering is sometimes called the sandwich method online. Neither the leaflet nor the AAD page uses that name. The AAD does say that your dermatologist may recommend you apply a smaller amount, use the retinoid less often, or apply moisturizer first. It adds that you should make these changes only with your dermatologist’s help. That is the safe version of the idea: ask first, then adjust.
What should you skip while using tretinoin?
MedlinePlus names the products that can cause trouble. It says not to use other topical medications, especially benzoyl peroxide, hair removers, salicylic acid and dandruff shampoos with sulfur or resorcinol, unless your doctor says otherwise. If you’ve used any of them recently, it says to ask your doctor whether you should wait before starting tretinoin.
The same page warns against products with a lot of alcohol, menthol, spices or lime, such as shaving lotions, astringents and perfumes. These can sting your skin, especially when you first use tretinoin. It also says to use only non-medicated cosmetics. The Retin-A leaflet adds that you shouldn’t use artificial sunlamps while on therapy.
If you’re already using other acne products, tell your dermatologist before your first night. Ask which ones to pause and which to keep.
How do you protect your skin while using tretinoin?
Sun protection is part of the routine, not an extra. The Retin-A leaflet says therapy may make skin more susceptible to sunburn and that treated areas should be protected even on hazy days. The AAD advises a non-comedogenic sunscreen that is broad-spectrum, SPF 30 or higher, and water resistant, applied to all skin that clothing doesn’t cover.
The leaflet also recommends a moisturizer, or a moisturizer with sunscreen, that won’t aggravate acne every morning after you wash. MedlinePlus adds that wind and cold can be particularly irritating to treated skin. Here is a practical note from running this service: buy the moisturizer and sunscreen before your first night. Supplies ordered after your skin gets tender make for a rough week.
What happens in the first weeks, and what if your skin flakes?
Many people have a rough start. MedlinePlus says your acne will probably get worse during the first 7 to 10 days and that you should continue using the medication. It adds that sores should improve in 2 to 3 weeks, and sometimes after more than 6 weeks of regular use. The Retin-A leaflet says early discomfort or peeling usually subsides within 2 to 4 weeks.
New blemishes can show up around week 3 to 6, and the leaflet says it’s important to keep going. It says that if the medication is going to help you, you should notice continued improvement after 6 to 12 weeks. For acne treatment plans in general, the AAD says it takes at least 6 to 8 weeks before you start to see fewer breakouts.
For general skin care during therapy, the leaflet advises a mild, non-medicated soap, avoiding frequent washing and harsh scrubbing, and patting dry. MedlinePlus says your doctor may tell you to use a skin moisturizer for dryness. If the skin stays raw, send your dermatologist a photo and ask about using less cream or applying it less often. For ordinary dryness, make schedule changes only with their approval.
Some reactions need a phone call. MedlinePlus says to call your doctor right away for itching, rash, hives, or pain or discomfort at the treatment area. The Retin-A prescribing information adds that sensitive skin may become excessively red, swollen, blistered or crusted. In that case, it says the medication should be discontinued until the skin’s integrity is restored, or adjusted to a level the patient can tolerate. The patient leaflet is more direct: if you have severe or persistent irritation, discontinue use and consult your physician. It also says to stop therapy until your skin recovers if you get sunburned.
What if you miss a night or stop using it?
If you forget a night, MedlinePlus says to apply the missed dose when you remember, unless it’s almost time for the next one. In that case, skip the missed night. Don’t apply extra to make up for it.
Stopping on your own has a cost. MedlinePlus says that if you stop using tretinoin, the improvement may gradually disappear. The leaflet says not to stop treatment at the first signs of improvement and to continue regular application until your physician instructs otherwise. Reorder your refill before the tube is empty. Operating this service, we see refills lapse right as skin starts to look better, which is the moment the leaflet says not to stop.
How does this connect to the rest of an acne plan?
Tretinoin is one tool among several. The AAD notes that a dermatologist may include more than one topical medication in a plan because acne has different causes. Our tretinoin before-and-after article covers what progress looks like, and our tretinoin article for men covers shaving and beard lines. To compare it with other options, see retinol versus tretinoin and Accutane versus tretinoin.
On the clinic side, The Goal Is Clear says plans may include prescription topicals, oral antibiotics, or Accutane® when the dermatologist agrees it’s a fit. Every case is reviewed by a U.S. board-certified dermatologist licensed in your state, and a prescription is never guaranteed.
Common questions about using tretinoin cream
Should I put moisturizer on before or after tretinoin? The Retin-A leaflet recommends a noncomedogenic moisturizer every morning after you wash. The AAD says a dermatologist may recommend applying moisturizer first, especially if your skin needs a stronger retinoid. Ask your dermatologist which order fits your prescription.
Can I use tretinoin every day? Both MedlinePlus and the Retin-A leaflet describe daily use at bedtime. The leaflet also says a physician may advise every other night to start, especially for sensitive skin. Follow the schedule your prescriber gave you.
How long does tretinoin take to work? MedlinePlus says acne sores should improve in 2 to 3 weeks and sometimes more than 6 weeks. For acne treatment plans in general, the AAD says it takes at least 6 to 8 weeks before you see fewer breakouts. Results vary from person to person.
Can I use tretinoin with benzoyl peroxide? MedlinePlus says not to use other topical medications, especially benzoyl peroxide, unless your doctor says otherwise. The AAD notes that a plan may include more than one topical medication, so ask your dermatologist before mixing products.
Where do I start if I don’t have a prescription? Tretinoin is a prescription medicine, so you’d start with a review. You can take the quiz, upload a front photo and a side photo, and a board-certified dermatologist reviews your case within 24 hours. A prescription is never guaranteed, and the dermatologist makes that call.
What is the next step if tretinoin isn’t enough?
Follow the directions on your own prescription, keep sunscreen in the morning routine, and give the medication time before judging it. If irritation doesn’t settle, or acne isn’t responding after the time your dermatologist expects, tell them. That conversation is how a plan gets adjusted.
If topicals aren’t enough, ask about other options. Our pages on Accutane® explain isotretinoin, which is a different drug. Medication is billed separately by the partner pharmacy, and some insured patients pay as low as $0 for the prescription. See pricing for how the Clear Course works.
