This is a common condition, usually a harmless one in which patches of skin become darker in color than the normal surrounding skin. This darkening occurs when an excess of melanin, the brown pigment that produces normal skin color, forms deposits in the skin.
This condition may be referred to as dark spots, melasma, sun spots or sun damage or even acne and many others. All these are responses to the fluctuating hormones. People with darker skin tone are more prone to hyperpigmentation, especially with excess sun exposure.
PREVENTION OF HYPERPIGMENTATION
Avoiding sun exposure is the best way to prevent hyperpigmentation, although that is not always realistic to achieve. Wearing SPF, hats, and applying topical antioxidants can also help keep hyperpigmentation at bay.
There are different natural treatments out there or products which contain active ingredients used in the treatment or prevention of hyperpigmentation:
Licorice extracts; Research suggests that a licorice extract called glabridin can have anti-inflammatory, antioxidant, and skin-whitening effects. People can use creams containing glabridin on areas of hyperpigmentation.
Vitamin B3 also known as niacinamide: This is known to prevent melanin from reaching the surface of the skin and protects it from additional UV damage. Research shows that niacinamide is an effective skin lightening compound that works by inhibiting melanosome transfer from melanocytes to keratinocytes.
Vitamin C: One of the most researched-backed skincare ingredients. The fresh vitamin C powder is the most effective way to derive the antioxidant benefits you need. Buffering of Vitamin C with ferulic acid increases its efficacy by making it more stable as it naturally oxidizes and loses potency in its liquid form.
Turmeric: Studies have shown turmeric skincare products reduce hyperpigmentation for up to 14 percent within 4 weeks of consistent use.
Resveratrol; A powerful antioxidant and a naturally occurring compound found in plants like grapes and berries. Studies have shown that resveratrol can also significantly decrease melanin production.
Superoxide Dismutase: Research shows that Oxidative stress caused by UVB induces the secretion of melanocyte growth and activating factors from keratinocytes, which results in the formation of cutaneous hyperpigmentation. Therefore, a beneficial strategy would be to increase the antioxidant abilities of skin cells. Superoxide Dismutase 1(SOD1) an antioxidant enzyme is known to exhibit antioxidant properties.
