Topical application of tretinoin significantly lightens postinflammatory hyperpigmentation; to a clinically minimal but statistically significant degree, it also lightens normal skin in black persons.
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.
Read below to find out how long it takes for tretinoin to work. Most people start to see the benefit of daily derm-grade retinoid use around 6 weeks. If used every 2-3 days, then it would take around 10 weeks to see. If only used once weekly, it may take up to 3 months to start seeing results.
Pigmentation is caused by a group of natural skin pigments called melanin. Retinoids suppress the production of melanin and hence reduce discoloration.
Tretinoin (Retin-A) is considered the first-line treatment for AN. When used regularly, it can help thin and lighten the skin in affected areas.
“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.
Tretinoin helps your skin cells replenish their collagen, improves the texture of your skin, evens out your skin tone, and increases the tightness of your skin (Yoham, 2020; Zasada, 2019).
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.
Uneven skin tone, or hyperpigmentation, can be due to sun damage, age, hormonal changes, medications, and skin injury (like from acne scars or cuts). In one clinical study with Black patients, tretinoin was effective in treating uneven skin tone with minimal overall lightening6.
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.
Azelaic acid for skin lightening
The same property that makes azelaic acid effective for the treatment of inflammatory hyperpigmentation also enables it to lighten skin that's discolored by melanin.
Using benzoyl peroxide topically will give you even-looking skin tone due to its bleaching properties. With regular use, it might also make your skin appear brighter.
Papaya, banana, lemon, honey, and gram flour mask: These ingredients contain vitamins and minerals that can naturally lighten and nourish the skin. They may be mashed into a paste, applied all over the face, and washed off after 20 minutes.
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.
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.
Researchers found Niacinamide is an important ingredient in skin lightening, which works to stop the transfer of melanin pigment (responsible for the darkening of the skin) to skin cells (keratinocyte). Niacinamide decreases hyperpigmentation and lightens skin gradually after using it for a long duration.
When using retinoids to reduce the appearance of fine lines and wrinkles, the more consistent you are, the better the results will be. Any side effects you experience are temporary. Long-term use of tretinoin achieves and maintains your healthy, naturally glowing skin.
Retinoids are useful in the treatment of hyperpigmentation because they reduce epidermal melanin by blocking the transcription of tyrosinase, induce desquamation, disperse keratinocyte pigment granules and enhance epidermal cell turnover via epidermopoiesis.
How does tretinoin work? Tretinoin will increase the number of new cells in the skin, increase blood supply, decrease the dark color of sun spots, and increase collagen production. The creams only work where applied and the active ingredient cannot be detected inside the body when applied to the face and hands.
Retinol is a Vitamin A serum, and it can lighten your freckles. It's a great solution for freckle removal, because the serum is suitable for any skin type — even sensitive skin. And it doesn't just help with freckle reduction.
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.
According to the NCBI, hyaluronic acid is often used in products designed to address visible wrinkles and improve skin elasticity. Benefit #3: Brighten. Products formulated with hyaluronic acid can also brighten skin's appearance. Skin will appear smoother and plumped with hydration after using.
Derived from vitamin A, retinoids — such as tretinoin (Retin-A, Renova, Avita) — that you apply to your skin may improve the appearance of stretch marks less than a few months old. Tretinoin, when it works, helps to rebuild a protein in the skin called collagen, making the stretch marks look more like your normal skin.
