Understanding the Science behind Spray Tanning

Spray tanning works by utilizing a chemical reaction between the active ingredient, dihydroxyacetone (DHA), and the outermost layer of the skin cells. DHA is a colorless sugar derived from plant sources, such as beets or sugar cane, and it is approved for external use by the FDA. When the spray tan solution, containing DHA, is applied to the skin, it interacts with the amino acids in the dead skin cells, resulting in a temporary tan look without any exposure to the sun’s harmful UV rays. This process, known as sunless tanning, provides a safe and convenient alternative to traditional tanning methods.

The Role of DHA in Spray Tanning

DHA, the active ingredient in spray tanning, plays a crucial role in the tanning process. When it comes into contact with the amino acids in the dead skin cells, DHA undergoes a chemical reaction that leads to the appearance of a tan. This reaction occurs on the outermost layer of the skin, known as the stratum corneum, and does not penetrate any deeper. As a result, spray tanning provides a temporary tan that typically lasts for about 5 to 7 days, depending on various factors such as skin type, skincare routine, and exposure to water or exfoliation.

Spray tanning formulas contain different concentrations of DHA, allowing for different levels of darkness. It is important to note that spray tanning does not provide any protection against the sun’s UV rays, so it is essential to continue using sunscreen with SPF to protect your skin from sun damage.

Spray Tan vs. Sun Tan: The Fundamental Difference

Unlike sun tanning, spray tanning does not involve exposing your skin to UV rays, which can cause skin damage, premature aging, and increase the risk of skin cancer. Sun tanning requires spending time in the sun or using tanning beds, both of which expose the skin to harmful UV radiation. On the other hand, spray tanning offers an instant color transformation without any exposure to UV rays.

With spray tanning, you can achieve a natural-looking tan without the risk of tan lines, sunburn, or skin damage. The tanning solution used in spray tanning is carefully formulated to provide a natural color that complements your skin tone, giving you a beautiful sun-kissed glow. This natural color avoids the risk of looking orange, which is a common concern associated with spray tanning.

Debunking Common Myths about Spray Tanning

There are several myths and misconceptions surrounding spray tanning that may deter some individuals from trying this method of achieving a tan. Let’s debunk some of the most common myths:

Spray Tan Makes You Orange: Myth or Reality?

One of the most prevalent myths about spray tanning is that it will leave you looking orange. However, this myth is far from reality. Professional spray tanning formulas are carefully formulated to avoid any orange tint. The tanning solutions used by spray tan technicians are customized to suit different skin tones, ensuring a natural-looking tan that complements your complexion.

The risk of an orange tan can also be mitigated by choosing high-quality spray tan brands and experienced technicians. Different brands offer different formulas, so it’s important to communicate your desired outcome to the technician and choose a brand known for providing a perfect tan look. With proper application and the right formula, spray tanning can give you a beautiful, sun-kissed glow without any orange hues.

Does Spray Tanning Cause Skin Damage?

One concern individuals may have when considering spray tanning is whether it causes any damage to the skin. Unlike sun tanning, spray tanning does not cause skin damage or increase the risk of skin cancer.

Spray tanning works at the surface level of the skin, and since there is no exposure to UV rays, the risk of skin damage, sunburn, or sun-related skin conditions is significantly reduced. The active ingredient, DHA, is FDA-approved for external use, ensuring its safety when applied to the skin.

When getting a spray tan, it is important to choose a reputable salon that uses high-quality, dermatologist-approved tanning products. Following the recommended post-tan care, including moisturizing and avoiding excessive sun exposure, will help maintain a healthy tan.

Like any beauty treatment, spray tanning has its pros and cons. Let’s take a closer look at both sides of the spray tanning coin.

The Bright Side of Spray Tanning

Achieving a sunless tan through spray tanning is a safe alternative to UV exposure, ensuring a perfect tan without the harmful effects of UVB rays. The use of dihydroxyacetone (DHA) in spray tan solutions reacts with the proteins on the skin’s surface, providing a natural bronzer without damaging the skin’s DNA or harming the mucous membranes. Whether it’s for a big event or just to add some color, spray tanning offers a customizable option, perfect for any time of year.

Potential Downsides of Spray Tanning

When considering sunless tanning, there are potential downsides that should be taken into account. Improper application can lead to an orange or uneven color, highlighting the importance of caution and proper technique. Allergic reactions or skin irritation are also possible, especially for individuals with sensitivities. Additionally, there is the risk of temporary staining of clothing or bedding, which is an important factor to consider before scheduling a spray tan, particularly before a big event. Furthermore, sunless tanning may not last as long as traditional tans, necessitating frequent touch-ups, and can be expensive compared to other tanning methods.

Safety Measures for Spray Tanning

Safety should always be a top priority when considering any beauty treatment, including spray tanning. Fortunately, spray tanning is generally considered safe when performed by trained professionals using high-quality products. Here are some safety measures you should be aware of:

Is Spray Tanning Safe for Pregnant Women?

Spray tanning is generally safe for pregnant women, but it’s best to consult your doctor first. Some tanning solutions may have chemicals that could potentially harm the fetus. Some pregnant women may choose to avoid spray tanning and explore other methods of achieving a sun-kissed glow.

Precautions to Take While Spray Tanning

When preparing for a sunless tanning session, exfoliate your skin to create an even surface for the perfect tan. Refrain from using lotion, deodorant, or makeup to avoid interference with the tanning solution. Opt for loose, dark clothing to prevent staining and aid the tan’s development. After the session, avoid showering or sweating for at least 8 hours to allow the tan to fully develop. Regular moisturizing is essential for prolonging the life of the tan, especially before a big event.

Choosing the Right Spray Tan Option for You

Understanding the contrast between spray tans and traditional tanning methods is crucial. Choose a spray tan that matches your skin tone and desired darkness level. Prepare your skin by exfoliating and avoiding specific products. For maintenance, moisturize and prevent excessive water exposure. Select a reliable provider and inquire about their products and application process to ensure a perfect tan.

Can Spray Tans be Customized according to Skin Type?

Spray tans can indeed be customized based on your skin type. Skilled technicians adjust the solution and technique according to your skin tone and preferences. Fair-skinned individuals may choose a lighter shade, while those with darker skin can go for a deeper shade. Communicate your desired outcome and concerns with your spray tan technician for the best results.


To conclude, spray tanning is a safe and convenient way to achieve a sun-kissed glow without the harmful effects of UV rays. The science behind spray tanning involves the use of DHA, a colorless sugar that reacts with the amino acids in the outermost layer of the skin to produce a temporary tan. Contrary to common myths, spray tanning does not make you orange or cause skin damage when done properly.

It is important to prepare your skin before getting a spray tan and follow post-tan care tips to maintain your tan for longer. While there are some potential downsides to spray tanning, such as the need for regular touch-ups and the risk of allergic reactions, taking necessary safety measures can minimize these risks. Ultimately, choosing the right spray tan option for your skin type and preferences will help you achieve the best results.
