Vitiligo: what it is, why sun protection matters most, and what skincare cannot do
Vitiligo is an autoimmune condition in which pigment-producing cells are lost, leaving sharply defined patches of skin with little or no pigment, often symmetrical and often around the hands, face and body openings. No cosmetic product restores pigment, and anything claiming to is over-claiming. Diagnosis and management belong to a dermatologist, and early assessment is worth having, because actively spreading vitiligo is generally approached differently from long-stable patches.
What is happening
백반증 (baekbanjeung) involves immune-mediated loss of melanocytes, the cells that produce pigment. The result is patches that are milk-white rather than merely lighter, with a fairly crisp border against normal skin, and hair growing within a patch may turn white too. It often appears symmetrically, commonly on hands, wrists, face, around the eyes and mouth, and in areas of friction. It may be stable for years or extend in episodes. It is associated with other autoimmune conditions, which is one reason a proper medical assessment is useful.
What it gets confused with
Post-inflammatory hypopigmentation, where a patch loses some pigment after eczema, a burn or a treatment, is far more common and usually recovers slowly on its own. Certain superficial fungal conditions produce pale scaly patches, particularly on the trunk in humid weather. Several other pigment conditions exist. These are distinguished by examination, sometimes using a specialised lamp, and they are managed completely differently — which is the entire argument against deciding what you have from photographs.
Sun protection is the practical priority
Depigmented skin has lost its own UV defence and burns readily, so protection is a health matter, not a cosmetic one. High-SPF broad-spectrum sunscreen applied generously and reapplied, plus clothing, hats and shade. There is a second reason: tanning the surrounding skin increases the contrast and makes patches far more conspicuous, so people who protect thoroughly often find the patches less visible. Korean sunscreens carry both an SPF number and a PA rating for UVA, and both matter here.
Camouflage, honestly framed
Cosmetic camouflage products, high-coverage colour-matched makeup and self-tanning preparations can reduce contrast temporarily. That is legitimate and helps some people considerably. It is also purely cosmetic and washes off, and no serum, cream or supplement on the open market repigments skin. Treat 'repigmenting' cosmetic claims with scepticism. Medical options exist and are the dermatologist's territory. The psychological weight of visible vitiligo is real and well recognised; it is a reasonable thing to raise at that appointment too.
