Tanning on elbows and knees usually fades gradually as your skin naturally renews itself, which can take a few weeks to a couple of months depending on your skin type, sun exposure, and skincare habits.

To help speed up the fading of tan, you can:

• Keep the skin moisturized to support healthy skin regeneration.
• Gently exfoliate once or twice a week to remove dead skin cells.
• Apply sunscreen daily to protect the skin from further tanning.
• Consider using skin brightening creams like Lacsoft Cream, which contains lactic acid to promote skin peeling and renewal. However, use such creams cautiously and ideally after consulting a dermatologist, as they can cause dryness or irritation.

Patience is important since skin color normalization takes time. If you notice persistent discoloration or any unusual skin changes, it is best to consult a dermatologist for personalized advice and treatment options.
