- Specific Limitations and Comments : Use of the term "sunscreen" or similar sun protection wording in a product's labeling generally causes the product to be subject to regulation as a drug or a drug/cosmetic, depending on the claims. However, sunscreen ingredients may also be used in some cosmetic products to protect the products’ color. The labelling must also state why the sunscreen ingredient is used, for example, "Contains a sunscreen to protect product color." If this explanation isn’t present, the product may be subject to regulation as a drug (21 CFR 700.35). For more information on sunscreens, refer to Tanning Products
