Spotted or patchy discoloration over the body without symptoms is often due to post-inflammatory hypopigmentation, pityriasis versicolor, or keratinization disorders like ichthyosis vulgaris. It’s unlikely to be just dead skin if salicylic acid and exfoliation haven’t helped.
Next Steps
An online consultation with a dermatologist is recommended to assess the pattern closely—some conditions need oral or prescription-based topical treatments beyond OTC products.
Health Tips
Avoid over-exfoliation. Use a gentle urea/lactic acid-based moisturizer (like Ureaderm or Lactoderm) and limit hot showers. Sun protection helps prevent contrast from becoming more visible.
