One of the tretinoin creams is used to treat fine wrinkles, dark spots, or rough skin on the face caused by the damaging rays of the sun. It works by lightening the skin, replacing older skin with newer skin, and slowing down the way the body removes skin cells that may have been harmed by the sun.
Doctors who tested the cream found that it lightened or cleared up the age spots in more than 80 percent of users. They concluded that Retin-A, along with using sunscreen and staying out of the sun, "is an effective, nondestructive approach to improving and sometimes clearing" these spots.
Retin-A can improve skin texture and fade dark spots and freckles because it causes skin cells to turn over more rapidly. It shrinks dilated pores and improves cell turnover within the pores so they are less likely to clog and become blackheads and whiteheads.
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.
Retinoids minimize the appearance of wrinkles, bolster skin's thickness and elasticity, slow the breakdown of collagen (which helps keep skin firm), and lighten brown spots caused by sun exposure.
“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. Icecreamwala recommends starting with a retinol that is 0.3 or 0.5 percent.
Retinol can be effective in lightening the skin and reducing the appearance of dark spots. It does so by promoting skin shedding, which improves cell turnover rate and hinders the activity of the enzyme tyrosinase, which encourages the production of melanin.
While using tretinoin, avoid sun exposure.
Tretinoin can increase your skin's level of sensitivity to sunlight and ultraviolet light, meaning you may develop a sunburn easily or experience more severe symptoms of UV damage.
Topical application of tretinoin significantly lightens postinflammatory hyperpigmentation; to a clinically minimal but statistically significant degree, it also lightens normal skin in black persons.
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.
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.
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.
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.
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.
For the purposes of skin care, tretinoin can be thought of as a more concentrated version of retinol. This means that tretinoin is stronger than retinol. This difference in strength can help guide your decision-making when it comes to choosing a skin care product. Your skin is affected by more than what you put on it.
In patients with sun-damaged skin, improvements in the skin usually are seen within the first 3-4 weeks of treatment. Brown spots begin to fade after 6-8 weeks.
Go Strong. Retinol and vitamin C are two of the best ingredients for fading dark spots. Try SkinMedica Lytera Skin Brightening Complex, a "blend of vitamin C and retinol that's reliably effective," says Francesca Fusco, a dermatologist in New York City.
Tretinoin gel, cream, or lotion requires a prescription because it's more powerful than retinol. Doctors prescribe tretinoin to treat skin conditions like: Acne. Psoriasis.
Skin Discoloration
Tretinoin can fade spots on the face, evening out your skin tone and helping to hide the blotchy coloration that can affect many people's facial skin. In some cases, however, tretinoin can also cause small patches of skin to darken, producing noticeable skin discoloration.
Unless your doctor tells you otherwise, it is especially important to avoid using the following skin products on the same area as tretinoin: Any other topical acne product or skin product containing a peeling agent (eg, benzoyl peroxide, resorcinol, salicylic acid, or sulfur).
Microneedling can help improve the appearance of dark spots on the skin. During the microneedling for dark spots, the platelets in the blood help kickstart a rejuvenation process, one that results in the creation of newer skin cells that are healthier than what they replace.
Age spots are caused by overactive pigment cells. Ultraviolet (UV) light speeds up the production of melanin, a natural pigment that gives skin its color. On skin that has had years of sun exposure, age spots appear when melanin becomes clumped or is produced in high concentrations.
