“If the retinol you're using is too strong for your skin causing inflammation, darker skin tones may have a higher risk of discoloration, or hyperpigmentation, from the use of it," she adds. Dr.
Tretinoin is thought to cause hyperpigmentation and a poorly tolerated dermatitis when applied to black skin.
The major adverse effect of tretinoin is mild skin irritation, especially when the more effective, higher concentrations are used. Temporary photosensitivity and paradoxical hyperpigmentation can also occur.
It might take two or three weeks of using Retin-A (treitinoin) to see any benefits. However, in some cases, it may take six weeks or more.
Tretinoin is also used to treat unwanted pigmentation and uneven skin tone caused by aging and sun damage. Known as “hyperpigmentation,” skin discoloration can occur over time as your body produces excessive amounts of melanin in certain areas of the skin.
At night, use a retinol product. Retinol causes the skin cells to turn over. That begins the process of removing the pigmented cells that are there. As you peel off the dark spots, your skin replaces them with normally pigmented cells.
Think of Tretinoin as floss for your face. It works to open pores, helps turnover the skin, evens the pigment tone and texture.
If you're using topical tretinoin to reduce wrinkles, discoloration, age spots, and/or rough feeling skin, it can take 3–4 months or up to six months before you see results.
In theory, retinol makes your skin cell turnover faster. The increased cell turnover temporarily sloughs off more dead skin cells. This creates a lag time before new, healthy cells come to the surface of your skin. Your new skin is exposed before it's ready, and redness or discoloration, and irritation is the result.
Retinol also stimulates collagen production, which is another way it diminishes dark spots. “Collagen helps promote skin cell turnover, which helps peel and fade away dark spots,” says Dr.
6: Myth: If you have peeling or redness, you should stop using the retinoid. With retinoids, it's often a “worse-before-better” type of situation. Typical side effects include dryness, tightness, peeling, and redness — especially when first starting out.
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.
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.
"You can use tretinoin or [over-the-counter] retinols forever."
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.
Generally, it is fine to use tretinoin every night, but you may not want to because of the initial side effects, especially when you first start. You should only use tretinoin as prescribed to avoid significant skin irritation, redness, and other side effects.
Generally speaking, dermatologists say purging should be over within four to six weeks of starting a new skin care regimen. If your purge lasts longer than six weeks, consult your dermatologist. It could be that you need to adjust the dosage and/or frequency of application.
Start with topical OTC whitening creams. “Treatments containing ingredients like vitamin C, licorice root, and kojic acid help reduce hyperpigmentation by inhibiting tyrosinase, an enzyme responsible for the formation of skin-darkening melanin," says Ni'Kita Wilson, a cosmetic chemist.
Hyperpigmentation acne may fade over time, but if the original spots were deep, it may be permanent. Although some topical and surgical therapies can speed up the fading process, it can take several months to years.
This increases the concentration of melanin in the epidermis, creating a temporary darkening of the spots. So, the darkening is what you want to see. It means the pigment is coming up and is ready to be shed away. You might be tempted at this point to over-exfoliate in an attempt to speed up the process even more.
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.
During the first 3 weeks you are using tretinoin, your skin may become irritated. Also, your acne may seem to get worse before it gets better. It may take longer than 12 weeks before you notice full improvement of your acne, even if you use the medicine every day.
Keep Your Face Clean
Touching your face or allowing oil or bacteria to build up can also increase the side effects of the tretinoin purge. Only touch your face with clean hands and leave your skin to do its thing. Also try not to pick at flaky or dry skin caused by the purge. The dryness will dissipate over time.
While prescription-strength retinoids may have an effect in a matter of weeks, it can take up to 6 months for OTC retinols to produce the same results. You may notice a difference in conditions like acne after 12 weeks, but sun damage and signs of aging can take much, much longer to improve.
