The study also suggests that retinoids are a preferred choice for scars and post-inflammatory hyperpigmentation. As retinoids are more potent than niacinamide, they can often cause more side effects. Retinol may trigger inflammation and irritation that causes: burning, tingling, or tightness of the skin.
Niacinamide helps hydrate skin, treats hyperpigmentation, promotes skin elasticity, decreases redness and blotchiness and acts as an antioxidant, fighting free radicals. Research has shown that niacinamide can help fade hyperpigmentation on the skin.
Retinol, a form of vitamin A, “is a multitasker with improvement in hyperpigmentation, acne and texture while also increasing collagen production to minimize fine lines and wrinkles,” says Love.
Using niacinamide before retinol works well. So does combining them into one product. A 2016 study found that a product containing retinol, niacinamide, hexylresorcinol, and resveratrol improved fine lines, sallowness, wrinkling, hyperpigmentation, and skin tone.
“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.
Peer reviewed studies suggest you should consult your doctor if you're not seeing any results by week 12. 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.
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.
Retinol has similar benefits, but it's stronger than niacinamide. It's also known to cause irritation, redness, and dry skin. Pairing the two ingredients is safe and can make retinol easier to use. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol.
These two anti-aging ingredients aren't entirely different. In fact, retinol is a type of retinoid. However, retinoid most often describes more powerful prescription products, while retinol generally refers to weaker over-the-counter (OTC) formulas. As board certified dermatologist Dr.
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.
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.
Niacinamide can concurrently rebuild healthy skin cells while also protecting them from damage caused by ultraviolet rays. Treats hyperpigmentation. Some research has found 5 percent niacinamide concentrations can be helpful in lightening dark spots.
How long does niacinamide take to work on hyperpigmentation? In mild skincare conditions, you'll notice visible results within two weeks. Based on most clinical studies performed on people with stubborn concerns, we can estimate that niacinamide can improve hyperpigmentation in 4-8 weeks.
“Studies have shown that after 12 weeks, there is an improvement in fine lines, wrinkles, skin elasticity, and skin tone,” he adds. Other studies show that a 5% concentration of niacinamide benefits hyperpigmentation after potentially just four weeks.
Retinoids work best if you use them daily. Specifically, they should be used at night because some types are deactivated by light and air. It's important to start slowly and allow your skin time to adjust. Using too much too quickly can cause redness, dryness, and irritation.
The fact is, most topical retinoid serums tend to contain higher concentrations of the active ingredient. They also tend to be light to the touch and rarely leave behind a sticky residue. So in that case, it does appear that a serum is the “better” choice over a topical retinoid cream.
Retinoids reduce fine lines and wrinkles by increasing the production of collagen. They also stimulate the production of new blood vessels in the skin, which improves skin color. Additional benefits include fading age spots and softening rough patches of skin.
First, vitamin C works to help improve the look of dark spots, fine lines, wrinkles and sagging skin. Then, retinol steps in to help improve skin's elasticity. The result is that retinol and other retinoids may help improve skin's texture while helping to minimize the look of fine lines.
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.
According to Ayodele, a chemical peel is also a great way to fade post-inflammatory hyperpigmentation, as "it will help the skin to exfoliate quickly and fade the discolouration." Alpha-hydroxy-acids such as glycolic, lactic and mandelic acid work by dissolving the 'glue' that holds dead skin cells together, revealing ...
Chemical peels, laser therapy, microdermabrasion, or dermabrasion are all options that work similarly to rid skin of hyperpigmentation. These procedures work to gently remove the top layer of your skin where the dark spots lie.
In the clinical studies, niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use. Conclusions: The data suggest niacinamide is an effective skin lightening compound that works by inhibiting melanosome transfer from melanocytes to keratinocytes.
In one study, government-financed researchers found that Retin-A reversed cervical dysplasia, an extremely common condition that occasionally leads to cervical cancer. In the other, funded by the makers of Retin-A, scientists found that the ointment can fade and even erase moles called dysplastic nevi.
Light or laser therapy: Depending on the cause of your dark spots, your dermatologist will either recommend light or laser treatment. These technologies can treat sun damaged skin, conditions like psoriasis, age spots, melasma, and other types of dark spots.
