How is a Woods lamp used in cosmetic dermatology?

Woods lamp is a valuable tool in cosmetic dermatology. Here are its applications:

1. **Chemical Peels**
- **Administration**: Woods lamp can be used after applying a chemical peel to ensure proper application and avoid over-treatment. Salicylic acid and fluorescein sodium are commonly added to chemical peels to create fluorescence. Salicylic acid produces a green fluorescence, while fluorescein sodium produces a yellow-orange color. This helps in assessing the depth of pigment and the effectiveness of the peel.

2. **Sunscreen Application**
- **Assessment**: Woods lamp can evaluate the proper application of sunscreen, especially in hard-to-reach areas like the back. This ensures that sunscreen is applied evenly and adequately, providing optimal protection.

3. **Tetracycline Compliance**
- **Evaluation**: Woods lamp can be used to assess patient adherence to tetracycline by examining the toenails for yellow fluorescence.

4. **Dihydroxyacetone (DHA) Application**
- **Assessment**: DHA is a chemical in sunless tanning cosmetics often used to cover vitiligo lesions. Woods lamp can determine the actual size of vitiligo lesions, as DHA fluoresces a salmon color and vitiligo lesions are bright blue-white.

In summary, Woods lamp is a versatile and valuable tool in cosmetic dermatology, aiding in the administration and assessment of various cosmetic procedures and treatments.
