1. Increased Sun Exposure: Sunscreen may give users a false sense of security and cause them to spend more time exposed to the sun, which increases their risk of skin cancer.

2. Allergic Reactions: Some users may develop an allergic reaction to the ingredients in sunscreen which may increase their chances of developing skin cancer.

3. Inadequate Protection: Not all sunscreens are created equal and some may not provide adequate protection against UV radiation, increasing the user's risk of skin cancer.

4. Free Radical Production: Sunscreen ingredients, such as titanium dioxide and zinc oxide, may in fact cause an increase in the production of free radicals when exposed to UV radiation, which may contribute to skin cancer.

5. Ozone Depletion: Some sunscreen ingredients, such as oxybenzone, are known to contribute to ozone depletion which may increase the amount of UV radiation reaching skin cells, increasing the risk of skin cancer.
