Can this condition be remedied, and what should I do? (Hong Van, Tay Ninh)

Answer:

Rapid skin whitening in a short period is an abnormal sign. Many whitening products of unclear origin may contain corticoids, mercury, or strong bleaching agents. While these ingredients quickly brighten skin and reduce acne, they also weaken the skin's natural protective barrier.

According to dermatological organizations, the uncontrolled overuse of corticoids or bleaching agents in poor-quality products can thin the skin, making it prone to peeling, irritation, dilated blood vessels, and increasing the risk of hyperpigmentation due to excessive rapid whitening. When skin is damaged, UV rays from sunlight penetrate deeper, stimulating pigment cells to produce excessive melanin, leading to skin darkening.

Some products also contain mercury, which inhibits melanin formation for quick skin whitening. However, this effect is only temporary. Prolonged use can cause dermatitis, burning sensations, and increased hyperpigmentation. More dangerously, mercury in cosmetics can be absorbed through the skin, potentially affecting the eyes, nervous system, kidneys, and hearing if used long-term.

Given that your skin has developed hyperpigmentation after using rapid whitening cosmetics, you should immediately stop using all suspicious products and seek a dermatologist's assessment of the damage. Do not attempt to continue using other hyperpigmentation treatments or whitening products on your own to avoid worsening the condition.

Skin requires a long time to recover. You should schedule regular follow-up appointments to monitor progress and select appropriate treatment methods, minimizing the risk of hyperpigmentation recurrence or spread.

During the skin recovery phase, prioritize mild moisturizing products from reputable sources that are suitable for sensitive and vulnerable skin. Diligent daily sun protection, combined with covering your face with a mask, sunglasses, and a wide-brimmed hat when outdoors, helps limit further melanin formation. Ensure a balanced diet rich in green vegetables and fresh fruits, adequate water intake, and sufficient sleep.

You may consider supplementing with natural essences such as sakura essence (from cherry blossoms), pomegranate extract, L-glutathione, collagen, and P.leucotomos (from ferns). These essences support the regeneration of the skin's protective barrier, control melanin formation, help fade hyperpigmentation, and enhance the skin's natural radiance.
