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 your scarring. Tretinoin in several forms has been tested successfully as an effective way to treat acne scars.
It can take up to 12 weeks to see results from using tretinoin for acne.
If the acne scar isn't very deep, topical treatments such as tretinoin topical (commonly known as Retin-A), microdermabrasion, or chemical peels may work to minimize the appearance of scars. These treatments remove the outermost layer of the skin and promote collagen production.
Common side effects of tretinoin
Even though tretinoin topical creams are great for treating acne, acne scars, fine lines, wrinkles, and skin discolorations, they can still cause side effects, just like any other medication. Here are some of the most common tretinoin side effects: Blistering. Crusty skin.
"You can use tretinoin or [over-the-counter] retinols forever."
The researchers found that when the subjects used tretinoin cream for acne scars consistently, 79 percent of the participants showed flattened acne scarring. The treatment was most effective on younger acne scars, as well as with narrow, indented icepick scars.
Many tretinoin users experience a “purge” during the first several weeks of treatment. During this period, acne — the very problem tretinoin is supposed to treat — often gets worse, resulting in everything from the occasional whitehead to severe breakouts.
After 4-6 weeks, your skin will get used to tretinoin and will begin to be noticeably smoother and more even. A lot of the initial irritation will settle down and true “retinization” of your skin is in full force.
Tretinoin Does Not “Bleach” Your Skin
Contrary to popular belief, tretinoin is not a “bleaching agent” or medicine designed specifically to lighten your skin tone. While tretinoin can even out patches of hyperpigmentation and cause a mild change in your skin tone, it doesn't affect melanin synthesis.
Remember, that 'retinoid uglies' are likely to be temporary, and it will take time before you see the end result. You have three skin layers—the epidermis, dermis, and subcutaneous tissue. Your epidermis is your visible layer, and renews approximately every 28 days.
But, to help treat current breakouts and prevent future ones, there's a need to keep pores unclogged and encourage skin cell turnover. Instead of using harsh scrubs, opt for a chemical exfoliant. Cleansers and serums containing AHAs (like glycolic acid), BHAs (like salicylic acid), and retinols can all help.
If you stop using the medication or are inconsistent with your treatment, any improvements you see may disappear over time. Always use the product as prescribed by your healthcare provider (Rodan, 2016).
As a result of its effects on your skin's cellular turnover speed, tretinoin reduces the appearance of wrinkles, evens out your skin's pigmentation and also treats skin issues such as acne. The end result is smoother, younger looking skin that's much less affected by fine lines, wrinkles or other common signs of aging.
Tretinoin is an anti-cancer ("antineoplastic" or "cytotoxic") chemotherapy drug. Tretinoin is classified as a "retinoid." (For more detail, see "How Tretinoin Works" section below).
Retinoids help mitigate those issues in a variety of ways. They thicken the epidermis through increased cell proliferation at the top level. They increase the production of natural chemicals (such as hyaluronic acid) in your skin that keep it plump and moist.
Commonly reported side effects of tretinoin include: pleural effusion, dyspnea, edema, fever, hypotension, leukocytosis, weight gain, headache, hypercholesterolemia, hypertriglyceridemia, increased liver enzymes, nausea, visual disturbance, and vomiting.
“This will make your skin look older and accentuate wrinkles” — which is probably not what you're going for when you start using the stuff. And there's no question that retinol makes your skin more sensitive to the sun.
Pending potency, OTC retinol can take up to six months to see results." That's not to say you won't see any benefits upon the first few uses. Nussbaum explains that in the short term, the benefits are that your skin will be exfoliated of dead skin cells and your pores will be unclogged.
It can range from minor pimples to cystic acne, as well as dryness, redness, and peeling. Also, it is important to remember that retinol isn't the direct cause of acne. Acne breakouts which occur during the purge phase would have developed on their own and retinol only speeds up their appearance.
You might also get more breakouts once you start using retinoids. Keep calm and stick with it. “It's common to see acne get worse before it gets better, as the retinoids can cause a mass 'purge,'” says Robinson. Basically, as skin cell turnover increases, new clogs rise to the top.
Tretinoin can help dark spots fade, allowing you to have a more even skin tone. It decreases the amount of melanin in your skin cells (Zasada, 2019). When used for discoloration, tretinoin is usually combined with other skin-lightening products, sometimes in the form of a chemical peel (Lawrence, 2021).
