2. With a history of allergic/phototoxic reaction (Lidocaine, Tegaderm, Suture strips, sunlight)
3. With a negative mini-grafting test
4. With a personal or a family history of skin cancer (non-melanoma skin cancer: first degree family members, melanoma: any family member)
5. With a personal history of photosensitivity and/or phototoxicity disorders
6. With skin type I (according to Fitzpatrick classification I-VI)
7. Who are pregnant
8. Who are taking medications known to cause photosensitivity and/or phototoxicity and chronic or very frequent use of any medication that can influence the UVB response (e.g. tetracycline, retinoids, sulfonamids, psoralens, Non-Steroidal Anti-Inflammatory Drugs [NSAIDs])
9. With other skin diseases that would impair evaluation of repigmentation, such as psoriasis and eczema
