Fans of fake tans may want to sit down for this.
Dihydroxyacetone—that’s DHA to you— which is the active ingredient in self-tanners (even clean ones) and spray tans (none of which are clean) “has the potential to cause genetic alterations and DNA damage,” according to a panel of scientists in an investigation done by ABC News.
Now before you run to the bathroom and ditch your Chocolate Sun, let’s take a closer look at what we know so far.
What are the news reports saying?
That DHA has the potential to cause genetic alterations, DNA damage, and cancer.
What’s DHA anyway?
DHA is a sugar that interacts with amino acids in the top layer of your skin to produce pigment called melanoidins; that’s the brownish tanned look these products achieve. DHA can be manufactured synthetically, or it can be derived from natural things, like beet sugar or cane sugar. It was approved by the FDA for topical use in 1977 (and many orange tans ensued!) and is widely accepted as nontoxic when applied to the skin.
So is it toxic?
Some research showed that when it’s applied in the form of a lotion, DHA does not migrate past the stratum corneum, the outermost layer of skin that’s also sometimes called the “dead skin layer.” Which sounds gross, but it’s good news, we thought, for your organs and your blood if you’re applying it in a cream as opposed inhaling it in the form of a spray tan or a spray-on self tanner.
Up until now, there’s been the most concern about spray tans, because the application method means you might inhale the stuff. Even the FDA, which is typically mum about all things cosmetics-related, has a warning on its website about them. Which means that for the love of all things good (and good looking) you should not be getting a spray tan!
Fine. But I’m good to go with a self tanner, right?
Not so fast.
FDA reports dating back to the 1990s, obtained through a Freedom of Information Act request, cited research that some DHA can migrate to the living layers of the skin after all. How much of it—and where it goes from there—is anybody’s guess.
And I dug up some research from 1962 showing that DHA turned up in blood samples after topical application as well. Dr. Darrell Rigel, an NYU professor of dermatology, told ABC News: “What you showed me certainly leads me to say I have to rethink what I’m doing and what I’m saying because there’s … a real potential problem there.” I’ll say. Every dermatologist I’ve ever been to has told me that if I want to tan, which thank goodness I do not, that I should use a self tanner.
So what’s the bottom line?
As always, it’s up to you. But because the research that’s just now getting attention—even though it’s by no means new—shows that when DHA gets into your blood or migrates to your organs through inhalation, it can cause DNA damage and possibly cancer…
I’ll keep digging into it, but for now, DHA is out for me.
If you decide to continue to use self-tanner, some words of advice: First, treat it like you treat your favorite conventional going-out lipstick and use it only for special occasions, like a wedding, a job interview or a hot date. I’m pretty bruisey on my legs, so I may keep mine around and use it before weddings or something. I’m on the fence about that right now.
And if you are going to use a self-tanner, use a cleaner formula. Most conventional ones are filled with dyes, synthetic preservatives, fragrance and all of that other stuff we generally try to avoid putting on our and in bodies. If you’re not sure if yours has dye in it, you can do one of two things: read the ingredient label (harder) or look at it and see if it’s brown (easy).
We’ll continue to look into this, but we want to know So what are you going to do with this news? To self tan or not to self tan?

The gorgeous girls at Well+Good put two of our favorite self tanners to the test! Last year, Alexandra reviewed one of Lavera’s self-tanners and I told you I was nuts about Chocolate Sun (still am! using it all the time!), so we were giddy about this post.
Here’s what Well+Good had to say about theirs….. And don’t forget to tell us in the comments: What’s your favorite self tanner?
It’s tough getting tan these days.
Slathering your body in baby oil and baking on a beach chaise has been verboten for a couple decades now. And recently, we reported on the hidden chemicals that may be lurking in your salon spray tan.
One safer option? An all-natural, organic self-tanner. Because you apply it yourself, you’re way less likely to inhale DHA, the active tanning ingredient that’s meant for your skin, not your lungs. And since a self-tanner lists ingredients on the bottle, you’ll know exactly what your pores are soaking up.
We tested two pure and popular products, Lavera Glow & Go Spray Self Tanner, a natural brand from Germany that’s sold in drugstores for $29.50, and Chocolate Sun Sunless Tanning Cream, an indie luxe brand that sells for $40, to see which tanner would come out on top.

It might seem a little late in the summer for a self-tanner review—except no, it isn’t! This is exactly when we all start losing our tans and yet the weather is still nice enough for bare legs. If you like a little bronzage, or if you’re pale as hell and bruise when someone so much as pokes you (ahem), then self-tanner can be a boon.
Interesting factoid we explain in more detail in the book: The active ingredient in most self tanners is DHA, which can be naturally derived from beets or cane sugar. It’s a simple carb that reacts with the amino acids in the top layer of your skin to produce that nice browny color. Go nature! The trick is finding a self-tanner with natural DHA and no extra crap like dyes (the thing that makes it look brown topically), fragrance (to mask the gross chemical smell many self tanners have), preservatives and so forth.
Anyhow, we found one we absolutely love. Chocolate Sun, based out of California, has a line called Cocoa Glow that we are pretty wild about. First of all, the smell. It smells like cookies—a delicious mix of coconut, cocoa, almonds and vanilla—which is a delightful change from the oddly pungent smells of chemical self-tanners.
Second, because there’s lots of coconut oil, almond oil and sunflower oil, it doubles as a lotion, and leaves legs looking nicely hydrated and fresh.
Third, it works! I tried the one for light skin—it comes in three shades—every other day last week on pretty bruisey legs, and I loved the very gentle tan it gave me. It didn’t totally hide my bruises—nothing can—but it gave a nice evening effect overall.
A dear friend, who is more olive toned and tans obnoxiously well, has been using the medium shade all summer, and she looks evenly tanned as well, and always smells great. This is a definite recommend.
Have you tried any you love?
