Here's the breakdown:
* Tanning creams (self-tanners) contain dihydroxyacetone (DHA) and/or erythrulose. These chemicals react with the amino acids in the top layer of your skin to create a temporary brown color. They don't actually tan your skin like sun exposure does, but they create a similar effect.
* Sun exposure accelerates the tanning process. If you use tanning cream and also expose yourself to the sun, you'll get darker faster.
* However, sun exposure is harmful. The sun's UV rays damage your skin, causing premature aging, wrinkles, and an increased risk of skin cancer.
Therefore, it's not recommended to use tanning creams and sunbathe simultaneously. You can achieve a tan with self-tanners alone, but you'll need to apply them regularly to maintain the color.
Here's a safer approach to achieving a tan:
1. Use a self-tanner. Choose a product that matches your skin tone and apply it evenly.
2. Protect your skin from the sun. Use sunscreen with an SPF of 30 or higher every day, even on cloudy days.
3. Consider a gradual tanner. These products contain lower concentrations of DHA and erythrulose, allowing you to build a tan gradually over time.
Remember, the safest way to protect your skin is to avoid sunburns and prolonged sun exposure. Choose sun-protective clothing, seek shade during peak sun hours, and use sunscreen regularly.
