The magic of DHA & how it gives you that gorgeous glow
Spray tanning is a popular method of achieving a bronzed, sun-kissed glow without exposing your skin to harmful UV rays. At the heart of spray tanning is a key ingredient called DHA, or dihydroxyacetone. But how does DHA work to give you a tan? Let's take a closer look.
What is DHA?
DHA is a colourless sugar that is derived from plant sources like sugar beets and sugarcane. It has been approved by the FDA for use in cosmetic products since the 1970s. When applied to the skin, DHA reacts with the amino acids in the dead skin cells on the surface of your skin to produce a brown pigment called melanoidins. This process is known as the Maillard reaction.
How does DHA give you a tan?
When you get a spray tan, a fine mist of DHA is applied to your skin using a spray gun. As the DHA reacts with the amino acids in your skin, it produces a brown pigment that darkens the surface of your skin. The longer you leave the spray tan solution on your skin, the darker the colour will develop.
DHA only affects the dead skin cells on the surface of your skin, which is why spray tans are temporary and only last for about 7-14 days. As your skin naturally exfoliates, the dead skin cells that have been darkened by the DHA will slough off, gradually fading your spray tan. This is why it's so important to exfoliate and moisturise!
Is DHA safe?
DHA is considered safe for use in cosmetic products, including spray tans. However, it's important to note that DHA only affects the dead skin cells on the surface of your skin and does not penetrate the deeper layers of your skin. It's always a good idea to do a patch test before getting a spray tan to ensure you don't have an allergic reaction.
It's also important to remember that spray tanning does not offer any protection against UV rays. If you plan on spending time in the sun, be sure to apply a broad-spectrum sunscreen with an SPF of at least 30 to protect your skin from damage.
In conclusion, DHA is a safe and effective way to achieve a natural-looking, temporary tan through spray tanning. By understanding how DHA works to give you a tan, you can make informed decisions about your spray tanning experience and enjoy a beautiful, sun-kissed glow all year round.
