Why Make-Up Flashback Happens and How to Avoid It

Ah, the dreaded make-up flashback! Celebrities like Angelina Jolie, Nicole Kidman and Miley Cyrus aren’t immune to it, even with their hordes of make-up artists:

Here’s the science behind make-up flashback, and how to avoid it.

What causes make-up flashback?

The harsh white markings are caused by silica, an ingredient in many translucent powders, particularly those labelled as “HD”. (Note: silica is not the same as silicon and silicone!) it-cosmetics-bye-bye-pores-IMG_8765 The silica used in makeup is fumed silica, a type of amorphous silica which has been processed to give it a large surface area. This means that it’s great as a microscopic sponge for soaking up oil (kind of like activated charcoal but colourless).

It’s also fantastic for diffusing light – all the tiny surfaces scatter light at different angles, giving a blurry, matte texture, making your skin look flawless on HD video (hence the HD label).

But not when direct flash comes out!

The harsh, front-on, white light of a flash is already pretty notorious for causing white patches on any mildly reflective surfaces (e.g. oily patches) directly facing the flash, without any flashback-causing ingredients.

I’m never doing this again.

Because silica has so many surfaces (a bit like a mirrored disco ball), if you have enough on your face, there will always be a whole bunch of surfaces ready to pick up that flash and throw it back at the camera – hence the white flashback.

Some other ingredients that are white or reflective can also pick up light and cause lightened areas, but usually to a lesser extent. Titanium dioxide and zinc oxide, two physical sunscreen ingredients, can cause a whitish glow (which makes sense, since their ability to scatter light is partially responsible for their sunscreen ability!) – but not always. Shiny mica, shimmer and glitter will also get shinier with a flash.

What can you do?

1. Avoid direct flash photography

It’s pretty unflattering to begin with – but sometimes you can’t control the lighting.

2. Use silica powder, zinc oxide, titanium dioxide, mica, shimmer and glitter sparingly

The obvious thing to do is to avoid these ingredients altogether, but it turns out you don’t have to! Which is a relief, because these ingredients look pretty awesome in normal light.

Here are some photos of some translucent powders I own without and with flash. flashback-silica-products-IMG_8727sunlight-silica-products-IMG_8738 silica-flashback-IMG_8738 Left to right:

 I also tried out the following powders and didn’t get any noticeable flashback (I didn’t bother posting a photo since it literally just looks like my bare arm):

Essence Fix & Matte (All About Matt) Translucent Loose Powder

Ingredients: Aluminum Starch Octenylsuccinate, Polyethylene, Disodium EDTA, Sodium Dehydroacetate, Butylparaben, Ethylparaben, Methylparaben, Propylparaben.

Crop Mineral Loose Powder

Mary Kay Translucent Loose Powder

Surprisingly, the only product with severe flashback is It Cosmetics Bye Bye Pores Silk HD Anti-Aging Micro-Powder. The pressed version gave almost no flashback (there’s a little at the edges where there’s some fall out floating around).

Interestingly, the pressed version doesn’t have “HD” in the name, and has mica as the first ingredient rather than silica. Innisfree No Sebum Powder also unexpectedly didn’t give obvious flashback, even though, like the HD powder, silica is the first ingredient. What gives?

It’s mostly to do with the amount of silica you put on. The first ingredient in the ingredients list is in the greatest quantity in the product, but that could be 95% or 30%, depending on the product. The HD powder, like most HD powders, is primarily silica (>90%).

The Innisfree powder, on the other hand, has corn starch as the second ingredient – corn starch is sometimes the first ingredient in a powder, so it’s quite likely that there’s a fair bit of it in the product, and hence a fair bit less silica.

The take-home message here: use less silica. Silica powder isn’t really meant to be used as a setting powder – it’s intended to be used to add an extra blurring effect after the make-up’s been set. Use it sparingly, with a fluffy brush.

The same applies to the other flashback inducers – since the flash is proportional to the amount on your skin, use less, or combine it with another product that isn’t so high in flashback ingredients.

3. Use silica powder under make-up

If you’re mostly after the oil-soaking effects of silica, you can try using it under a liquid make-up instead of on top – this will kill the white reflection.

4. Test your make-up

This is THE most foolproof method for ensuring that your makeup doesn’t flash back – check it with a flash photo before the event! It sounds obvious now, right? Do a test run before your big day (whether it’s a wedding, graduation, formal, birthday), get the camera with the biggest flash, and get snapping.

Things that don’t work well

* Using water or makeup sprays after silica powder

Silica gel goes transparent when wet, so theoretically, wetting it will make it disappear. I loaded up my arm with HD powder, then sprayed the left side with Skindinavia Make-up Setting Spray and the right side with Avene Thermal Water, with a chunk of dry powder in the middle. Check out what happened immediately after spraying, then after waiting around for 2 minutes: silica-flashback-water-setting-spray-IMG_8790silica-flashback-water-setting-spray-immediate-IMG_8790silica-flashback-after-water-setting-spray-IMG_8790 The flashback doesn’t change with make-up setting spray, but while the water promisingly makes the flashback disappear for a couple of minutes, it comes right back after the water evaporates. Boo!

* Avoiding SPF

Some people recommend avoiding SPF together – but you don’t have to! Most SPF products actually don’t give flashback, as this article demonstrates. I used a flash to photograph a couple of cream products containing sunscreen:

It Cosmetics Your Skin But Better CC Cream (SPF 50: 9% titanium dioxide + 6.3% zinc oxide)

Jurlique Sun Specialist (SPF 40 PA+++: 7.5% Octyl Methoxycinnamate, 3% Butyl Methoxydibenzoylmethane, 2.75% Octocrylene)

I have a stripe of It Cosmetics HD Powder on the right as a comparison. I dusted the two cream products with a flashback-free translucent powder before taking the flash photo to kill the shine. sunlight-it-jurlique-silica-IMG_8757flashback-it-jurlique-silica-IMG_8757 Not much flashback, even the high zinc oxide/titanium dioxide CC cream (though it could potentially be worse once it’s all over your entire face and it no longer matches your neck).

Verdict

To eliminate the possibility of embarrassing white-dusted photos, use flashback-causing ingredients sparingly, and do a test run of your make-up under direct flash conditions. Better still, only let people take photos of you under carefully selected light conditions, and only from your good side!

    Oh dear, when I first read the title, I was like “What’s flashback?” and then I saw Angelina Jolie’s face and thought “OMG, who threw flour all over her?!” Thank you for this post! It was very informative, as always! I’m sure there are plenty of photos of me with flashback circulating somewhere on FB >_<

    Hi! I am getting married outside this summer and will be outside all day for pictures and during the ceremony. My make-up artist said NOT to use sunscreen before primer because it will cause a flashback and said to forego using SPF at all the entire day. I have super sensitive skin & this scares me – will products like Elta MD SPF 46 or the new Murad City Skin SPF cause this “flashback”? Both of these products (especially the Murad) leave Zero white case and blend in sheer and clear. Not your typical physical sunscreen. So my question is, could these be exceptions my make up artist doesnt know about it and can I wear them on my wedding day without causing white flash back? I look forward to hearing from you soon. Thank you so much!!

    Thank you! Now can you please go share this to Beauty YouTubers who constantly use these powders to bake or set makeup and complain that the products are ‘bad’ when in fact they have been using it wrong? So many good products get thrown under the bus because of the igorance of popular beauty “gurus”. :/ I am all for honesty and all for these products but a good reviewer should understand the science prior to making judgement. Its just unknown dishonest honesty.

    Ok, so what about this: I use a ‘transparent’ mattifying powder daily to kill the crazy shine that my 1/4-1/2 tsp of sunscreen leaves on my very already shiny (not oily) tretinoin treated skin. Today I saw myself in a venue with black light and didn’t know how quickly to run to a toilet to wash my face. My face looked like a Jackson Pollock painting: light dots all over my face. I googled and found this great article, and thought: ah yes, silica. But turns out: my powder doesn’t have any silica (or ZO, TO2) in it! It consists of mainly talc, aluminum starch octenylsuccinate and sapphire powder. Any idea which ingredient would be causing this? Crazy which things you have to take into consideration when using a face powder ?

      Black lights pick up all sorts of stuff unfortunately… I’d say it might be the talc or aluminium starch octenylsuccinate. Minerals are usually worse in black light!

    Hi Michelle, thanks a lot for your informative post! I would like to know whether Silica Dimethyl Silylate in the BH Cosmetics Studio Pro Matte Finish Pressed Powder would cause flashback? It’s listed after Talc, Mica, Methyl Methacrylate Crosspolymer, Dimethicone, Petrolatum, and Pentaerythrityl Tetraisostearate. Thank you so much!
