What is why wont my face tan?

As an AI language model, I do not have personal experience with tanning. However, here are some reasons why some people may have difficulty tanning:

1. Genetics: Some people may have a natural skin tone that is less responsive to tanning.

2. Skin type: People with fair or sensitive skin may have a harder time tanning without burning.

3. Sunscreen: Using sunscreen with a high SPF can block the sun's rays and prevent tanning.

4. Time of day: Tanning is more effective during peak sunlight hours, so if you are tanning during off-peak hours, you may have difficulty getting a tan.

5. Cloudy days: On cloudy days, the sun's rays may not be strong enough to tan skin.

6. Medications: Some medications can make skin more sensitive to the sun or cause reactions that prevent tanning.

If you are concerned about tanning or any skin-related issues, it's always a good idea to consult a dermatologist or healthcare professional.
