Thank you for your question and for sharing the photo. The lighter patch on your upper lip appears to be a condition called post-inflammatory hypopigmentation, which can result from previous irritation, acne, eczema, shaving, or even unrecognized trauma. In some cases, it could also be related to a condition like vitiligo, pityriasis alba, or tinea versicolor, though less common in this location. Common Causes: Post-inflammatory hypopigmentation: Often follows inflammation or trauma (such as shaving or a breakout). Vitiligo: An autoimmune condition causing pigment loss. It often appears symmetrically and spreads over time. Chronic irritation or dermatitis: From harsh products, friction, or allergens. Fungal infection (like tinea versicolor): Rare in this area, but may be possible. Treatment Options: Topical Corticosteroids or Calcineurin Inhibitors: May be used if inflammation or vitiligo is suspected. Gentle Skincare Regimen: Avoid harsh products or fragrances. Use mild cleansers and moisturizers. Tacrolimus (Protopic) or Pimecrolimus: Helpful in some pigment loss conditions like vitiligo. Camouflage Cosmetics: Products like Dermablend or Color Correctors can help mask the area. Phototherapy: In persistent cases of hypopigmentation, narrow-band UVB or excimer laser can sometimes help stimulate pigment return. Topical Pigmenting Agents: Such as mequinol, though results can vary and should be used under supervision. What to Watch For: If the spot is spreading If other light patches appear on your face or body If there’s scaling, itching, or discomfort In many cases, these areas are stable and not harmful. The chance of reversal depends on the underlying cause and the duration. Long-standing hypopigmentation may take time to respond or may persist.
