Topical tretinoin is a generic form of the acne medication Retin-A. Tretinoin can be purchased online or over-the-counter in cream or gel forms, but not in the same concentration as Retin-A. In the United States, purchasing topical tretinoin in the same concentration as Retin-A requires a prescription.
Typically, topical tretinoin is both a short-term solution and long-term treatment option for clearing up active breakouts. It’s used for hard-to-clear acne blemishes on your skin.
Tretinoin is effective for many people, but it’s not for everyone. Keep reading to find out what you should know before trying tretinoin for your acne.
Tretinoin is a retinoid, meaning it’s a form of vitamin A. Retinoids stimulate cell turnover on your skin. Dead skin cells are cleared off your skin more quickly as new skin cells rise to the surface. Quicker cell turnover opens your pores, releasing trapped bacteria or irritants that are causing your acne.
Retinoids like tretinoin also help your skin to regulate its natural oil (sebum) production, which can prevent future breakouts. They also have anti-inflammatory properties, which clear up active acne pustules.
Tretinoin for wrinkles
Tretinoin has been studied extensively for its impact on the visible signs of aging. Tretinoin cream has demonstrated both short-term and long-term effects on the appearances of wrinkles. That’s why tretinoin is a popular ingredient in many over-the-counter face and eye creams.
Tretinoin for acne scars
Tretinoin can also be used to decrease the appearance of acne scarring. Since tretinoin speeds up cell turnover on your skin, it can encourage new cell growth at the site of scarring.
Tretinoin in several forms has been tested successfully as an effective way to treat acne scars. Tretinoin is also sometimes used to prep skin for chemical peel treatments that target scarring.
Using tretinoin for acne can cause side effects. Not everyone will experience all of the side effects, and some may be more severe than others. Possible side effects include:
- burning or itching skin
- peeling or redness on your skin
- unusual dryness of your skin
- skin that feels warm to the touch
- skin that turns a lighter color at the site of application
It can take up to 12 weeks to see results from using tretinoin. If your skin seems irritated by using it, check with a doctor to see if symptoms are within the range of what’s normal for over-the-counter tretinoin.
If, after 8 to 12 weeks, you don’t see any improvement in your skin, speak with a dermatologist about prescription-strength tretinoin or other treatment options.
Tretinoin is not recommended for people who are pregnant or breastfeeding.
When you’re using tretinoin, be extra careful about your exposure to the sun. Like all retinoids, tretinoin can thin your skin, making it more prone to sun damage and sunburn. Make sure you wear a sunscreen whenever you’re going outside, and consider additional preventative measures like wearing a hat with a brim.
It’s extremely rare, but possible to overdose on over-the-counter tretinoin. Overdoses are more likely to occur in prescription-strength forms of this medication (such as Retin-A). Signs of an overdose include having trouble breathing or losing consciousness.
If you feel like you’re having an allergic reaction or experiencing serious side effects from tretinoin, discontinue use and seek medical attention immediately.
Other topical acne medications can interact with tretinoin and irritate your skin or aggravate side effects like burning on your skin. Unless they’re part of a plan you’ve discussed with your doctor, avoid using other topical skin treatments (such as benzoyl peroxide, salicylic acid, and products containing sulfur) while using tretinoin. Also, avoid products that dry your skin, such as astringents and cleansers that contain alcohol.
If you want to use tretinoin to treat acne, start by choosing a cream or gel that has a low amount (0.1 percent) of the active ingredient tretinoin. If needed, you can work up to higher amounts as your skin becomes accustomed to the treatment.
To apply tretinoin safely and effectively:
For best results, apply tretinoin once at bedtime so that it can absorb completely into your skin while you sleep. It’s best not to apply makeup in the hours immediately following this treatment.
Tretinoin is an effective long-term treatment for the treatment of acne. While it won’t work for everyone, studies show that tretinoin works to encourage cell turnover that can even skin tone, treat breakouts, and decrease the appearance of acne scarring.
Tretinoin can aggravate acne in the initial weeks of treatment, but in a few weeks, you should see results.
