The Safety and Effects of DHA-Free Tanners
With summer coming up, many people are looking for ways to get a sun-kissed glow without exposing their skin to harmful UV rays. This has led to an explosion in popularity of self-tanning products that provide color without sun damage. The active ingredient in most mainstream sunless tanners is dihydroxyacetone, more commonly known as DHA. When applied to the skin, DHA interacts with amino acids on the surface layers of the epidermis to temporarily darken the skin color. However, there is some controversy around DHA safety and side effects. This has led to increased interest in DHA-free tanning options.
What is DHA?
DHA is a simple carbohydrate that comes from plant sources such as sugar beets and sugar cane. It is approved by the FDA for use as a color additive in cosmetics to impart a temporary tan. When DHA is directly applied to the skin, it causes a chemical reaction with the amino acids in the outermost layer of the epidermis. This reaction produces compounds called melanoidins which create a tan color lasting about 5-7 days.
Most sunless tanning products today contain between 3-5% DHA. Brands recommend exfoliating skin before application and warn that it may stain or discolor clothing or fabrics. The shade of color achieved depends on the concentration of DHA, number of applications, and your natural skin tone.
DHA Controversies and Safety Concerns
While the FDA has approved cosmetic-grade DHA as safe, there are some lingering concerns about side effects and risks:
- Allergic reactions - DHA is known to sometimes cause contact dermatitis, itching, redness or rashes in those with sensitive skin or allergies.
- Skin toxicity - Some studies using high concentrations of DHA found mutations and DNA damage to human skin cells in labs.
- Free radicals - There is conflicting evidence on whether DHA exposure long-term may generate harmful free radicals that accelerate aging.
- Hormone disruption - Limited evidence points to DHA possibly interfering with estrogen and androgen activity.
- Inhalation risks - Spray tanning with DHA creates mist that may cause lung irritation if inhaled.
While more research is still needed, these potential health effects make DHA unappealing for many consumers. This has led to increasing demand for alternative tanners that don't contain this controversial additive.
DHA-Free Sunless Tanning Options
Fortunately, there are a handful of other ingredients and methods that provide a tanned appearance without having to use DHA:
Caramel Coloring
Caramel colors are made by heating sugars and are used as food colorings as well as cosmetic bronzers. Caramel-containing tanners last about 2-4 days and must be reapplied more often than DHA products. But they provide a natural-looking tan without the worries about DHA.
Erythrulose
Erythrulose is a natural keto-sugar found in some berries and mushrooms. While chemically similar to DHA, it appears to have a better safety profile. Erythrulose responds with proteins in the skin to trigger melanin production and gives a sunless tan about as dark as DHA. Some organic sunless tanners use erythrulose as an alternative to DHA.
Black Walnut Hull Extract
Black walnuts contain antioxidants called juglone that have been used for decades as natural dyes. Extracts from black walnut hulls create a brownish liquid that can darken skin when applied topically. Companies like Ecocert use walnut hull extracts in organic self-tanners.
Other Botanical Bronzers
A variety of plant oils, roots, and extracts have mild skin-darkening effects and are found in natural DHA-free tanning products. Ingredients like caramelized clove, cinnamon, coffee extracts, paprika, and turmeric root temporarily stain skin a honey-brown hue.
Tinted Moisturizers and Sunless Makeup
If you don't want to actually tan your skin, using makeup or tinted lotions can give the appearance of a glow without the UV exposure. Tinted moisturizers with mineral SPF protection add sheer color while hydrating and guarding skin.
For special occasions, opt for an all-over body bronzer. When applied evenly, these powders can make your skin tone look naturally sun-kissed without any tanning needed.
Spray Booth Tanning
Spray tanning booths apply a fine mist of tanning solution evenly across your entire body. This provides a highly customized tan you can control to your desired color intensity. DHA-free tanning booth solutions utilize alternative bronzers like erythrulose and caramel to avoid DHA exposure while getting an even application.
Finding the Best DHA-Free Self-Tanners
When shopping for the best DHA-free sunless tanners, look for these factors:
Type of Active Ingredients
Look on the ingredient list for “caramel”, “erythrulose”, “walnut extract”, etc. Call or email the company if you can’t find a full ingredient disclosure to ensure it is DHA-free.
Shade Range
Test out samples in light, medium and dark shades to match your skin tone. Many natural brands offer just 1-2 shades while others provide more color options.
Application Method
Creams, lotions, wipes, drops, and sprays all give different levels of control. Make sure the application method suits your needs and preferences.
Special Skin Types
Seek out tanners designed for sensitive skin or allergies if needed. Some products cater to dry, oily, mature, or acne-prone skin types as well.
Duration of Color
DHA-free tanners often don’t last as long as DHA self-tanners. Expect to reapply every few days for the darkest color.
Organic Ingredients
Many natural tanners use organic botanicals and are EWG Verified or meet Whole FoodsPremium Body Care standards. This provides extra assurance of skin safety.
Application Tips for Flawless DHA-Free Color
Follow these best practices for getting a beautiful, natural-looking glow with DHA-free self-tanners:
Exfoliate First
Gently scrub body and apply careful attention to dry areas like elbows, hands, feet, knees and ankles to slough off any dead skin. This ensures the tanner absorbs evenly.
Use a Tanning Mitt
Apply your DHA-free sunless tanner with a mitt rather than hands alone. This provides an extra smooth, streak-free finish.
Moisturize Problematic Areas
Put extra moisturizer on extra dry zones before tanning to prevent uneven coloring or patchiness.
Start Light
Test a small amount first, then build up color gradually if you want a deeper tan. Less is more!
Blend Thoroughly
Take time working the tanner into your skin for perfectly blended, natural-looking color from head to toe.
Let it Develop
Leave tanner on the recommended time prior to showering for the full color to surface. This is usually 6-12 hours.
Rinse Thoroughly
Shower with warm water only, no soap, to wash off the bronzing reaction and prevent streaking.
Moisturize Daily
Hydrated skin holds onto tanner better. Apply unscented body cream
FAQs
Is DHA completely safe to use on my skin?
While the FDA has approved DHA for use in cosmetics, some studies have raised concerns about potential toxicity, hormone effects, and free radical generation with repeated use. More research is still needed to determine the long-term safety of DHA on human skin.
How long does a DHA-free tan last?
Most DHA-free tanners last between 2-5 days depending on your skin type and application method. They tend to wear off faster than DHA self-tanners, which can persist up to 7-10 days.
What natural ingredients create a sunless tan?
Some botanical alternatives to DHA include caramel, erythrulose, black walnut hull extract, cinnamon, coffee, paprika, turmeric, and caramelized plant sugars. These provide varying degrees of temporary bronzing without DHA.
Should I exfoliate before applying a DHA-free tanner?
Yes, gently exfoliating removes dead skin cells so your DHA-free tanner absorbs evenly for the most flawless results. Pay extra attention to dry areas like knees, elbows and ankles.
What is the benefit of using an application mitt?
Using a tanning mitt rather than hands gives you better control and helps smooth product more evenly over the skin's surface. This prevents streaking and splotches for the most natural looking sunless tan.
