When should you apply tretinoin and all other retinoids?
According to Dr. Mohta, you should always apply tretinoin at night. This is because when retinoids are exposed to sunlight, they can create harmful substances and excite retinoid molecules. These reactions can cause immediate and long-term damage in your skin4.
Do you apply tretinoin all over your face?
Yes, Dr. Mohta says you should apply a very thin layer (pea-sized amount) of tretinoin to your entire face and neck.
What tretinoin strength should I use first?
Dr. Mohta recommends you start with a low (0.01% or 0.025%) tretinoin strength so your skin gets used to the medication.
Considering adding a specific tretinoin strength to your skincare routine? Begin your journey here: Tretinoin 0.025% cream | Tretinoin 0.05% cream | Tretinoin 0.01% cream.
How long should I use tretinoin for?
According to Dr. Mohta, it may be necessary to use tretinoin for at least 8 to 12 weeks before assessing its effectiveness, this is for the skin to adjust to the medication and for the full benefits to become apparent.
Dr. Mohta also mentioned that tretinoin can be used long term, even for many years. Tretinoin is commonly used for the treatment of acne and dark spots (hyperpigmentation), but it can also be prescribed for other dermatological concerns such as fine lines and wrinkles..
What is the sandwich method of tretinoin?
The sandwich method involves washing your face with a mild cleanser, patting it dry with a towel and waiting 30 minutes. After this time you can then apply a layer of moisturizer, wait 10 more minutes, apply a thin layer of tretinoin and wait 10 more minutes to then apply a final layer of moisturizer or a hyaluronic acid serum.
Why wait 30 min after washing your face to apply tretinoin?
You need to wait 20 to 30 minutes before applying tretinoin to ensure your skin is completely dry. If you apply it ahead of time, you risk irritating your skin. Using a micronized version of tretinoin or Altreno can minimize the risk of irritation.
How often should I use tretinoin in the beginning?
These are some recommendations Dr. Mohta usually gives her patients:
- First 2 weeks: Apply low concentration (0.01% or 0.025%) two nights per week
- Following 2/4 weeks: Apply tretinoin 3 times per week or every other night
- After 6/8 weeks of use: If your skin tolerates the product well, apply the product every night
- After 12 weeks: After 12 weeks of using the product on a daily basis. You may be able to increase the strength of the product (0.04%, 0.05% and 0.1%). People with sensitive skin can benefit from using micronized formulations.
How long does it take for tretinoin to work?
Most patients using tretinoin for the first time will begin to notice a positive effect after approximately 10 weeks, if they are using it every 2-3 days. Learn a week by week process of how long does tretinoin take to work.
Should I use tretinoin every night?
You should aim to use tretinoin every night, however, you must start slowly as your skin needs to get used to it. The first 2 weeks apply it 2 to 3 nights per week, after that try applying it every other day, and then if your skin can handle it, apply it every night. However, skip a night or two if your skin is irritated, because it will make it worse.
Potential side effects of tretinoin
To mitigate side effects, start with the lowest concentration and avoid direct sun exposure.
- Skin irritation and reddening
- Burning sensation
- Dry, flaky, and peeling skin
- Acne breakouts
- Sunburn5
Alternatively, patients may use micronized formulations of tretinoin to reduce skin irritation. There is a new tretinoin product in the market called Altreno which is much more gentle on the skin as its formulation includes: micronized tretinoin, collagen, hyaluronic acid and glycerin. In clinical trials this tretinoin version caused skin irritation to only 1% of patients using it6.
How do you maximize tretinoin results?
To maximize the results of tretinoin, start slowly, apply tretinoin at night on perfectly dry skin and between two layers of moisturizer, wear sunscreen with SPF 50 every morning, and combine with niacinamide or hyaluronic acid to minimize irritation.
Is tretinoin over the counter?
Unfortunately tretinoin is not an over the counter medicine. You need a doctor’s prescription.
What cannot be mixed with tretinoin?
You should not combine tretinoin with any other retinoid. Unless indicated by your dermatologist, you should avoid using these ingredients at the same time or on the same day as tretinoin: benzoyl peroxide, lactic acid, salicylic acid, and physical exfoliants.
What cancels out tretinoin?
The effectiveness of tretinoin can be reduced by sun exposure as tretinoin is photosensitive, which means it degrades in daylight. A study shows that benzoyl peroxide in conjunction with light exposure reduced the effectiveness of tretinoin gel within 24 hours under specific lighting conditions up to 80%. If your tretinoin tube has not been stored properly or if it has been open for more than 6 months can also reduce efficacy of the medication.
What is best paired with tretinoin?
Tretinoin should always be paired with a moisturizer and sunscreen with a SPF 50. In addition to these two items, you can also pair it up with Vitamin C (applied before your sunscreen in the morning) and hyaluronic acid or niacinamide 10 minutes after applying your tretinoin cream.
Do I need to wash tretinoin off in the morning?
Yes, it is recommended to wash your face every morning before applying vitamin C, your moisturizer and sunscreen with SPF 50.
Can you put hyaluronic acid over tretinoin?
Yes, in fact it is recommended that you apply hyaluronic acid over tretinoin as this ingredient complements the effects of tretinoin due to its ability to attract and retain moisture in the skin. Tretinoin can cause dryness and irritation, especially in the beginning, so adding hyaluronic acid into your skincare routine can help minimize these side effects.
Can I use vitamin C with tretinoin?
Yes, you can use vitamin C and tretinoin as long as you don’t apply them at the same time. You should apply tretinoin at night since it is photosensitive, and vitamin C in the morning after washing your face. When using tretinoin or vitamin C it is essential to apply sunscreen with SPF 50, even during winter, as these products make your skin more sensitive to the sun.

Can you use tretinoin if you have sensitive skin?
Yes, it is possible to use tretinoin even if you have sensitive skin or rosacea.
What is the tretinoin purge?
The so-called tretinoin purge is a common skin reaction that occurs when a patient uses tretinoin for the first time.
“Although research shows that tretinoin fights acne and is effective as an anti-aging ingredient; the skin goes under a “cleansing” process often referred to as skin purging,” says Dr. Mohta.
“The symptoms often associated with this process include intensified acne breakouts (for a short period of 2 to 6 weeks), severe skin dryness and peeling, redness and irritation. However, this process is temporary and once it’s over, in general, the skin will improve, and you will be able to see the positive effects of tretinoin,” she added.
When to contact your healthcare provider?
Dr. Mohta says that you need to make sure that the symptoms you are experiencing are within the realm of what is “typical” as far as side effects go. Call your healthcare provider if your skin irritation is causing you severe pain or if it gets too uncomfortable.
