In one study from , people with acne who used a. Interestingly, although the. Although a mild improvement was visible after four and eight weeks, the combined tretinoin and clindamycin treatment produced the biggest improvements after 12 weeks.
Many tretinoin users experience improvements sooner, while others may need to wait for slightly longer than 12 weeks for optimal results. Several different factors may affect the amount of time it takes for tretinoin to clear acne lesions and improve your skin:.
The severity of your acne. If you have very severe acne, it may take longer before your skin clears after you start using tretinoin.
The strength of the tretinoin cream. Most research suggests that creams containing a higher percentage of tretinoin for example, 0. How consistently you apply the medication. If you forget to use your medication or skip certain days, you may need to wait for longer to see improvements.
How sensitive your skin is to the effects of tretinoin. Some people experience faster results from tretinoin than others. Since no two cases of acne are identical, your results may take more or less time than the typical results timeline seen in studies.
Your use of other skin care products. Other skin care products, such as moisturizer or topical antibiotics, may enhance the results of tretinoin or affect its ability to be absorbed by your skin.
These skin care products may cause you to experience faster or slower results while you use tretinoin. Make sure to inform your healthcare provider about any other medications or skin care products you use before you start treatment with tretinoin. As we mentioned above, tretinoin may cause your acne to become more severe before it begins to clear up. During the first few months of using tretinoin, some people experience an increase in their level of facial acne.
During this period, your acne may become more severe. You might notice more pimples forming on your skin than normal, or that your existing acne lesions seem to become more inflamed and painful than they were before you started using medication.
In some cases, you may also experience side effects of tretinoin, such as dryness, skin peeling and flaking. Not everyone experiences the tretinoin purge, but for those who do, it can often be a particularly unpleasant few weeks. Like with many things in life, the key to passing through the tretinoin purge successfully is a mix of patience and determination. The tretinoin purge is almost always a temporary issue that will resolve on its own as your skin becomes more accustomed to the tretinoin cream or gel.
You can get through it by focusing on the long term and thinking about how your skin will look once the medication starts working. They may suggest applying tretinoin less frequently or switching to a lower concentration cream to reduce the severity of your symptoms.
However, in some cases, tretinoin may cause more severe side effects that require treatment and attention.
Although uncommon, tretinoin may cause more severe side effects, such as itching, hives and pain or discomfort. Our list of common and uncommon side effects of tretinoin offers more information on the side effects listed above, as well as the steps that you can take to manage them.
Overall, severe side effects from tretinoin are rare. In the event that they do occur, they almost always stop when you adjust your dosage or stop using the medication. Tretinoin has been approved by the FDA as a treatment for acne since the late s. During the last three decades, it also received approval by the FDA as a topical treatment for wrinkles and other common signs of skin aging.
The first is that tretinoin may cause complications if you have certain skin conditions, including atopic dermatitis eczema. The second is that tretinoin should only be used on healthy, uninjured skin.
Tretinoin is a very easy medication to use. To use tretinoin, closely follow the instructions provided with your meditation or by your licensed healthcare provider.
To wash away sweat, dirt and other substances, carefully wash your face with warm and a mild soap or facial cleanser. After washing, gently pat your skin dry using a clean towel. Simply washing your face is more than enough to remove dirt and bacteria. Apply a small amount of tretinoin to the areas of your face affected by acne.
If you have a liquid solution form of tretinoin, use a cotton swab or gauze bandage to apply it to your face. For most people, a pea-sized amount of the cream or gel should be enough to cover the affected areas of your face. The first few weeks of using tretinoin can be tough. Retina-A is used once daily before bedtime. Apply enough to cover the affected area lightly. Putting on a thick layer will not improve results and may only increase skin irritation.
Avoid applying Retin-A around the corners of the eyes, nose, or mouth. You should not apply it to open wounds, as this can cause pain and inflammation. Protect your skin from the sun, wind, and cold, as it will be more sensitive to the elements for several months after starting tretinoin. Daily sunscreen is advised.
Retin-A cream, gel, and liquid can be stored safely at temperatures under 80 degrees F. The medication does not require refrigeration but can be refrigerated if there is a risk of excessive heat exposure. Refrigerated Retin-A can also be soothing to the skin.
Retin-A gel is flammable. Keep the gel well away from open flames, and do not expose it to temperatures over degrees F. Keep the tube tightly sealed and out of the reach of children.
Discard any expired drugs. As with all drugs, Retin-A may cause side effects. While some of the initial side effects may resolve as your body adapts to treatment, others may be severe and require temporary or permanent discontinuation of the medication. Common side effects of Retin A include:. Retin-A is prescribed at the lowest effective dose to avoid side effects.
When first starting treatment, it may seem as if your acne is getting worse. This is not uncommon and is due to the effects of the drug on pimples developing deep beneath the surface of the skin. Do not stop treatment as these symptoms will eventually improve. Retin-A causes sun sensitivity photosensitivity by stripping away the outer layer of skin cells called the stratum corneum.
This exposes the underlying cells to the effects of UV radiation. Side effects can become severe if you are out in the sun too long, such as for work or while playing sports. You can minimize these effects by using sunscreen, though they may still occur to some degree.
Severe side effects of Retin-A include:. Treatment should be temporarily stopped if these side effects develop. Once the skin has healed, a lower dose should be prescribed. If the severe side effects return, other treatment options should be considered. On rare occasions, allergic contact dermatitis has been known to occur after applying Retin-A. Severe allergic reactions, such as anaphylaxis , can sometimes occur with oral tretinoin drugs, but they rarely do with topical drugs like Retin-A.
Retin-A can interact with certain medications, cosmetics, and skincare products. Chief among these are topical products that contain alcohol, sulfur, resorcinol , or salicylic acid. Using Retin-A with any such products can increase skin dryness. If products like these are being used, it is usually best to stop them and let the skin rest before starting Retin-A.
Tretinoin was once available as an oral drug called Vesonoid used for the treatment of acute promyelocytic leukemia APL. The drug has since been discontinued due to safety and efficacy concerns. Retin-A tretinoin is a prescription cream used to treat acne. It is an option your healthcare provider or dermatologist may recommend when over-the-counter medications and proper skincare fail to provide relief. Applied once nightly before bedtime, Retin-A will generally improve acne symptoms within several weeks, although there may be skin drying, flaking, and the temporary darkening of the skin.
Breakouts may also temporarily worsen before skin starts to clear. Retin-A should only be used in adults and children over Retin-A is often chosen by dermatologists to get rid of closed comedones. Additionally, it can help prevent new comedones from forming. It does this by increasing the rate of skin cell production to the areas that Retin-A is applied, making it more difficult for pores to become blocked and cause acne.
It might take two or three weeks of using Retin-A treitinoin before its benefits can be noticed. However, in some cases, it may require at least six weeks of regular usage before results will appear. No, Retin-A is not effective in reducing acne scars. At most, it might make superficial scars become less obvious.
Treatment of acne scars will depend on the type of scar. No matter which type of acne scarring is present, it will require professional help from a doctor or dermatologist. At first, using Retin-A might cause acne to appear worse than before.
This is a somewhat common symptom. If this happens to you, keep following the instructions given to you by a doctor or dermatologist. These symptoms will eventually clear up. When retinol is taken orally as a dietary supplement, it is used to help treat vitamin A deficiency.
It is also available as a cream and applied topically for skin care, often used to reduce wrinkles. Retinol is said to only be mildly effective as an acne treatment, so Retin-A might be better suited for that specific purpose. Dealing with acne can be frustrating.

Abstract Acne-focused dermatology expert groups have consistently recommended that most patients with acne be treated with a combination of topical retinoid and antimicrobial therapy. Funding : Galderma International. Role of Retinoids in Acne Management It is generally agreed that multiple molecular pathways are involved in acne, with four primary pathophysiologic mechanisms [ 3 , 10 , 11 ]: Abnormal desquamation within the sebaceous follicles that leads to obstruction of the pilosebaceous canal.
Androgen-driven excess sebum production. Altered immune system activity and inflammation. Open in a separate window.
Dose-Dependent Effects on Primary Acne Lesions The efficacy of individual topical retinoids increases with increasing concentration. Effects on Secondary Acne Lesions In addition to affecting primary acne lesions, topical retinoids have also been shown to act on secondary lesions including scarring and pigmentation because of actions in the dermis. Perceived Barriers to Use of Retinoids Efficacy in Inflammatory Acne There is a common perception that retinoids should be reserved primarily for comedonal acne [ 37 ].
Tolerability Topical retinoid therapy can be accompanied by cutaneous irritation, including peeling, erythema, irritation, or dryness, which typically are observed in the first few weeks of treatment and then subside [ 42 ]. Table 1 Strategies to minimize tolerability issues [ 7 , 53 , 69 ]. Take a detailed patient history Past tolerability problems? Educate patient Mild irritation can be part of the treatment process, but usually subsides within 1—2 weeks and can be managed with appropriate steps How to apply the retinoid in a thin layer fingertip or pea-sized dose Gentle cleansing regimen and avoiding over-cleansing Select most tolerable retinoid formulation for climate and season Titrate retinoid dose at initiation Apply retinoid every other day for first 2—4 weeks based on clinical trial evidence that this is when irritation is most likely to occur Apply a gentle, non-comedogenic moisturizer Use a short contact method for the first 2—4 weeks apply retinoid to full face for 30—60 min then wash off.
Necessity of Treatment Directed Toward P. Conclusions The scientific rationale for use of topical retinoids in acne is clear [ 2 , 3 , 37 ].
