The sun is great for your skin in many ways: it pumps it full of vitamin D, gives you a healthy glow and generates feel-good hormones. However, it’s no secret the sun can also be hugely dangerous. Overexposure to harmful UV rays can show up in the form of hyperpigmentation.
“Hyperpigmentation occurs when skin cells overproduce melanin, the pigment that adds colour to the skin,” says Pharmica superintendent pharmacist, Carolina Goncalves. “This overproduction can lead to visible patches of darker skin, often aggravated by environmental or genetic factors, such as sun exposure, hormonal changes, or inflammation.” Though pigmentation from the sun in the form of freckles is now rightfully embraced, the non-uniform appearance of hyperpigmentation can be a source of insecurity for many.
We hear from leading dermatologists and celebrity facialists on how to treat and prevent hyperpigmentation from the sun. What causes hyperpigmentation? Although sun exposure is hyperpigmentation’s leading catalyst, there are other factors that can contribute to the dark spots. “Hyperpigmentation results from overactive pigment cells and an excess of melanin in the skin,” says Sharon Hilditch MBE FCGI, CEO and founder of Crystal Clear Skincare, and facialist to Madonna , Nicole Scherzinger and Jude Law.
“It typically is due to excessive exposure to the sun’s UV rays, but hormonal changes during pregnancy, certain medications, and various medical conditions can also cause it.” Ho.
