How to start adapalene without irritation

Start adapalene 0.1 percent gel slowly. The UK NICE guideline says to begin a retinoid with alternate-day or short-contact use, for example washing it off after an hour, and to move to normal use once your skin copes. After that, the adapalene Drug Facts label sets the rules: once a day, a thin layer over the whole area that breaks out, and up to 3 months to see results.

What adapalene is

Adapalene is a retinoid, a medicine related to vitamin A. The American Academy of Dermatology (AAD) says a retinoid "works to clear your pores, and can treat blackheads, whiteheads, and some pimples," and that it can help lighten dark spots left after acne clears. The AAD's 2024 acne guideline gives topical retinoids a strong recommendation, its highest rating.

In the United States, adapalene 0.1 percent gel is sold without a prescription. The FDA approved over-the-counter use of Differin Gel 0.1 percent on July 8, 2016, for acne in adults and children 12 years and older. Before that, it needed a prescription. For children under 12, the label says to ask a doctor. In the UK, the NHS lists adapalene among the acne creams a GP can prescribe.

The directions on the label

The Drug Facts box on the tube is the official set of directions. Here is what it says.

Instruction	What the label says
How often	Once a day. More often will not work faster and may worsen irritation
How much	A thin layer over the entire affected area. If your acne is on the face, the whole face
Before you apply	Clean the skin gently and pat dry
Sun	Limit sun exposure, including tanning beds, and use sunscreen outdoors
Waxing	Do not wax hair where the gel has been applied
Damaged skin	Do not use on cuts, scrapes, eczema or sunburn
Pregnancy	Ask a doctor before use if pregnant or breastfeeding
Age	12 years and older

The leaflet inside the box is direct about spot use: "Differin Gel is not a spot treatment and should not be used to treat a single pimple." A pimple starts as a clogged pore under skin that still looks clear. The AAD says to spread a thin layer of acne medicine evenly over your acne-prone skin, for example over the forehead, nose and chin if you break out in all three places. A layer over the whole area reaches pores that have not turned into pimples yet.

A slow start: every other night, or wash it off

The label gives once-a-day use from the first day. NICE, which advises doctors in England, suggests a gentler start for benzoyl peroxide and retinoids. It says to start with alternate-day or short-contact application "(for example washing off after an hour)" to reduce the risk of irritation, and to move to standard use once the skin tolerates it. MedlinePlus says skin may become dry or irritated during the first 2 to 4 weeks of treatment, so those are the weeks a slow start helps most.

A slow start in practice:

1. Patch test first. How to patch test a new skincare product explains how.
2. Weeks 1 and 2: put the gel on every other night. On the nights in between, wash and moisturize only.
3. If your skin stings a lot, wash the gel off with water after 1 hour on gel nights, then put on moisturizer again.
4. When your skin copes, leave the gel on overnight, and then move to every night.
5. Put on moisturizer every night. The label's leaflet says a moisturizer "may help decrease dryness and other signs of irritation," and to avoid moisturizers with alpha hydroxy or glycolic acids, which may worsen irritation.

If irritation still bothers you after a few weeks, the AAD says a dermatologist may recommend a smaller amount, using the retinoid less often, or applying moisturizer first, and that these changes should be made with the dermatologist's help. Retinoid dryness and peeling covers what to do when the skin flakes.

Why acne can look worse before it looks better

The label says: "during the early weeks of use, your acne may appear to worsen before it improves (this is normal); continue using as directed, unless you get irritation that becomes severe." MedlinePlus explains one reason: in the first weeks, adapalene may bring pimples that were not visible yet to the skin surface.

Irritation is a second, separate effect. The label says redness, itching, dryness and burning are more likely in the first few weeks of use, and more likely again when you use more than one acne medicine on your skin at a time. The leaflet adds that irritation usually lessens after 4 weeks of continued use.

Neither effect means the gel has failed. Skin purging vs a real breakout explains how to tell this early flare apart from a reaction that means stop.

How to apply it, step by step

1. Wash gently. Use a mild cleanser and your fingertips. The NHS says to wash twice a day with a gentle cleanser and not to scrub, because scrubbing can irritate the skin and make acne worse.
2. Wait until your face is fully dry, 10 minutes after washing. The label says to clean the skin gently and pat dry before applying.
3. Spread a thin layer over the whole area. Keep it out of the eyes, nose and mouth, which MedlinePlus lists as places the gel should not go.
4. Wash your hands afterward, as the label directs.
5. Put on moisturizer once the gel has dried.

The AAD says dermatologists often recommend applying a topical retinoid in the evening. If you use it during the day, the label's leaflet says to let it dry before you put on sunscreen.

Using adapalene with benzoyl peroxide

Benzoyl peroxide reduces acne bacteria, and adapalene clears pores, so the two work on different causes of acne. Guidelines favor using both:

• The UK NICE guideline lists "a fixed combination of topical adapalene with topical benzoyl peroxide for any acne severity" as a first choice for a 12 week course. A fixed combination is one gel that holds both. In the US, each is also sold without a prescription as its own gel: adapalene under its FDA approval, and benzoyl peroxide at 2.5 to 10 percent under the FDA's acne rules.
• The 2024 AAD guideline lists "combining topical therapies with multiple mechanisms of action" as a good practice statement.
• The AAD says benzoyl peroxide is most effective when used along with another acne treatment that works on the other causes of acne.

The trade-off is irritation. The adapalene label warns that irritation is more likely "if using more than one topical acne medication at a time." That is why the slow start above matters even more for a pair. Start both together, every other night or washed off after an hour, and let your skin settle before you move to every night. Retinoid with benzoyl peroxide covers the pair in more detail.

Leave salicylic acid out while you start adapalene. It would be a third acne medicine, and the label says irritation rises with each one. The leaflet also lists abrasive cleansers and products with drying effects as things that make irritation more likely. For everything else you add, such as a new moisturizer or sunscreen, add one new product at a time so you can tell which one caused a reaction.

Sun protection every day

MedlinePlus says adapalene may make skin sensitive to sunlight or ultraviolet light, and the label says to limit sun exposure, including tanning beds, and to use sunscreen outdoors. This applies on every day you use adapalene, including cloudy days. The AAD advises a broad-spectrum sunscreen of SPF 30 or higher that is water resistant and labeled non-comedogenic, which means it will not clog pores.

How long to wait before you judge it

The American Academy of Dermatology says to use an acne product for 6 to 8 weeks before judging it, and that complete clearing generally takes 3 to 4 months. The adapalene label says it may take up to 3 months of once daily use to see results. MedlinePlus says the full benefit can take 8 to 12 weeks or longer.

NICE says positive effects can take 6 to 8 weeks to become noticeable, and tells doctors to review a first acne treatment at 12 weeks. Judging adapalene at week 2 or 3 means judging it during the weeks when the label says irritation is most likely. How long an acne routine takes to work covers what to look for at each week.

When to stop and ask a doctor

The label lists four reasons to stop adapalene and ask a doctor:

• You become pregnant, or are planning to become pregnant, while using it
• You have signs of an allergic reaction, such as itching, rash, hives, swelling of the lips or eyelids, or shortness of breath
• Irritation becomes severe
• You see no improvement after 3 months of once daily use

NICE goes further on pregnancy. It says topical retinoids are not to be used during pregnancy or when planning a pregnancy. Retinoids during pregnancy and breastfeeding covers the options that remain. The NHS says to see a GP if spots are deep, painful or causing scars, whatever you are using.

Where adapalene fits in a routine

Adapalene goes on at night, after washing and before moisturizer. In the morning, wash, moisturize and put on sunscreen. The complete acne skincare routine covers every step and product strength, and what order to apply acne products covers the order when you use more than one.

Skinli's sample plan starts adapalene 0.1 percent together with benzoyl peroxide 2.5 percent, every other night for 2 weeks and then every night: wash, wait until your face is fully dry, 10 minutes after washing, put on the benzoyl peroxide, wait 5 minutes, then the adapalene, then moisturizer. If your skin stings a lot, the plan has you wash the gels off after 1 hour for the first 2 weeks, then leave them on every other night in weeks 3 and 4.
