A glycolic wash-off exfoliating mask with 15% glycolic acid, 3% lactic acid, and tranexamic acid, designed to brighten skin, reduce hyperpigmentation, and improve texture.
This 15% glycolic acid mask earns consistent praise for visibly smoothing skin and fading dark spots from acne, melasma, and sun damage, often within days of use. The formula pairs glycolic and lactic acids for dual exfoliation and hydration, then adds tranexamic acid specifically to target stubborn pigmentation. Most gurus suggest starting with just a few minutes and building tolerance, and those with sensitive skin may want to patch test first, though many use it weekly or even overnight without irritation.

"For exfoliation I use the Dr. Idriss Major Fade Flash Mask [...] once a week. I really like it because it uses 15% glycolic acid as well as 3% lactic acid, which gets it into mini peel territory, [...] no joke percentages. I like this product for the delivery system, it's a wash off mask, so I can tailor my mini peel experience by how long I leave it on, usually around 10 minutes for me, sometimes only 7 if my skin feels more sensitive than usual."

"This really helps to heal up my hyperpigmentation from acne and inflammatory events faster, and it's giving my skin a much more refreshed quality and a smoother texture. I've used the Dr. Idriss Major Fade Flash Mask for about two years now, [...] and I really love it, I think it's great, but I just think it is very very expensive."
My Sephora Top 15 Skincare Picks
"Dr. Idriss Major Fade Flash Mask, let me tell you I did not want to like this product. The ingredients is what really drew me in. I was like this is for sure made by a dermatologist because they're really focusing in on some really key brightening active ingredients: glycolic acid, lactic acid, and tranexamic acid. Glycolic and lactic are AHAs so they work on the top surface of your skin to really resurface your skin in a way right."
THESE products made me LOVE AHA's!!
"Let's talk about the Dr. Idriss Major Fade Flash Mask. I really do credit this product as the product that made me fall in love slowly but surely with AHAs, particularly with glycolic acid, because that's really the cornerstone of this wash off mask. It's 15% glycolic acid, and that is quite a good amount."
My Top 5 Masks | 2025 Edition
"This mask actually really helped me to love AHA. This uses 15% glycolic acid, which is a lot of AHA. Glycolic acid helps to chemically exfoliate the top surface of the skin, helps to shed away the dead skin cells. It can help with skin tone, texture. [...] With long-term and consistent use, it can actually help with collagen production in the skin as well. It kind of helps to thicken up the skin, make it more firm, more youthful, more supple, and just rejuvenates the skin."
Top 20 Must-have Skincare Products At Sephora!
"Number one, Dr. Idriss Major Fade Flash Mask. This retails $48 for 50ml of product. I've really been enjoying adding this into my routine. This is a potent AHA mask, but unlike The Ordinary 30% AHA mask, I feel like this has been formulated in a really smart way that helps to sidestep some of the irritation. I also just think it's a more sophisticated formula."
Fade Hyperpigmentation in 3 Steps
"I told you that I'm a fan of this line and it's really been helping my skin, and this is a really nice one to use once or twice a week. I personally just use it once a week, and it really does give you that nice perk up to your skin. Not only does it help to brighten your skin, but the ingredients [...] will help with hyperpigmentation from acne, and they will also help for melasma, sun damage, and uneven or dull looking skin tone. It will really help with a lot of different concerns."
How I Cycle My Skincare Actives Through the Week | Routine and Tips
"The Major Fade Flash Mask from Dr. Idriss is a compound mask with glycolic, lactic, and tranexamic acid in here. Glycolic and lactic are AHAs, so they chemically exfoliate the top surface of the skin to remove dead skin cells, to create a smoother, brighter look to the skin. It helps with texture, it just kind of renews your skin."
4 Steps to Glowing Skin in Winter
"I've been obsessed with the Dr. Idriss Major Fade Flash Mask for about a year now. I absolutely love this. It uses 15% glycolic acid, now glycolic acid is probably the most potent AHA acid out there, one of the best known, and it shows really good results on the skin. 15% is quite a lot, but they actually bump up the AHA in this mask by including an additional 3% of lactic acid."
THIS is What I Do Weekly for Bright & Glowy Skin!
"This mask is from Dr. Idriss, it's the Major Fade Flash Mask and I absolutely love this because it's 15% glycolic acid and 3% lactic acid, so two very good AHA chemical exfoliants, and then there's also some tranexamic acid in this mask too which is a great brightening ingredient that targets pigmentation on the skin. I use the AHA once a week."
April Fave + Empties | Bringgreen, Dr. Idriss, Numbuzin, Aprilskin, P&L
"The AHA is really kind of helping to just kind of keep things under control. I've definitely noticed smoother skin, softer skin, brighter skin. It just really brings a clarity to the skin that was just like that kind of missing thing, you know, that thing I was yearning for and didn't know how to quite get it, and I feel like this mask has given that to me. So I am really impressed because I've had an uneasy relationship with glycolic acid and lactic acid and AHAs in general."

"I'm a major fan of the Major Fade Flash Mask from Dr. Idriss. I've been using this now for going on my second year. I do try to build this into my routine once a week. I do sometimes put it to the side in the winter just because winter has its own challenges with sensitive skin and dryness, but I do find myself recommitting to this exfoliation when it's spring. [...] This mask uses 15% glycolic acid and 3% lactic acid, both AHAs that are designed to really exfoliate the top surface of your skin."

"A really, really good product as an exfoliating mask. If you're someone just go the ordinary peeling solution doesn't agree with you. High strength peels don't agree with you. This is something you can definitely use. I highly recommend it."
"It has 15% glycolic acid, super strong alpha hydroxy acid. It also has lactic acid. This is definitely a powerful exfoliator but it works beautifully as a mask for anti-pigmentation for the hands and forearms. Love it. You will have to titrate if you have sensitive skin because, like I said, it took me gosh I think six months to build up a tolerance of wearing this on my face, maybe once a week for about 10 minutes. The first time I put it on I had to take it off in under a minute."

"Pillow Talk Derm sent me a couple extra of their Major Fade Flash Mask. This is a glycolic wash off mask, unlike the TLC by Drunk Elephant, the Framboos, this is a glycolic serum that you leave on overnight, this one you wash off. It's pretty potent. When I first started using it I could only use it for a couple minutes and then I had to wash it off, and then I built my tolerance up and I used it on my face and neck and decolletage to about 8 to 10 minutes once a week."

"And that is why I created the flash mask which has glycolic acid at 15% with lactic acid to brighten but it also has trannexyamic acid because on its own tranexamic acid doesn't work great topically. So when you marry it to an exfoliating acid you're really improving its chances of brightening."

Best Exfoliating Acids for Your Skin Type & Concern | Dermatologist Explains
"The Major Fade Flash Mask is a 15% glycolic acid mask, but products do combine acids with a 3% lactic acid as a bonus. The reason why I made it a mask is twofold. You should not be exfoliating every single night of the week. When it's a mask format, there's a barrier to entry, so you don't want to do it as often and therefore you want to exfoliate probably two to four times a week at most."
THE DEPUFFER IS BACK! | Dr. Shereene Idriss
"I use this two to three times a week at night only. I never exfoliate in the morning. The only time I've done it is before a photo shoot, because it does give a little smoother appearance. But the reality is I'll do it the night before and sleep with it overnight, which we don't recommend for everyone if you're sensitive, but I do do that."

"This is your exfoliating mask. It has 15% glycolic acid, lactic acid, and tranexamic acid. The reason why it comes in a mask is multifactorial. I wanted you guys to control where and how long you are exfoliating for. I don't want you guys putting some wet toner all over your face, getting it into your eye, dripping on your PJs. [...] So I wanted you guys to control where you apply it and for how long you apply it."

"If you have melasma you just want to throw everything at it, so combining it with an exfoliating acid allows it to work a little bit more efficiently, and that is why we mixed all three in the Dr. Idriss Major Fade Flash Mask. The beauty of a gel is you can pick how long you keep it on your face and where you apply it, so for me I always apply it on the high points of my face."

"The Flash Mask is an exfoliating flash mask which has alpha hydroxy acids like glycolic acid and lactic acid, glycolic being the strongest one and the smallest one so it goes the deepest and does the most work, lactic helping with hyperpigmentation and discoloration. But it's also married to tranexamic acid, which is not an exfoliating acid."

"It's 15% glycolic acid with lactic acid and tranexamic acid. Tranexamic acid [...] alone isn't great topically for melasma, but in combination with an exfoliating acid it works better, though the best form of tranexamic acid, if I'm being honest, is a prescription pill by mouth, and not everybody is a candidate for that. [...] The reason I like it as a mask twice a week and not a toner is because it comes in a gel form, so you can pick and choose where to apply it on your face."

"It's an exfoliating mask that comes in a gel format, so you can apply it to hard-to-reach areas. So if you already have, let's say, a brown spot, once the pimple is gone and you're trying to get rid of that brown discoloration, you can put a little bit of the flash mask on the spot every night to try to peel it off faster. But as long as there is inflammation and redness, you don't want to overexfoliate because you don't want to cause too much redness, too much inflammation."

The Flash Mask is meant to be washed off, so you're not worried about peeling with this."

"This is a mask intended to be used all over the face, but I will put it on the residual brown spot left behind almost every night until it's gone. Not when it's a juicy thick rich pimple, I'll use the hydrocolloid patch, but once it leaves a brown spot or a little bit of a red mark, I will use this on that red mark as it is flat, or that brown spot as it is flat, for three, four, five nights in a row until it disappears. It works beautifully overnight and then I wash it off in the morning."

"In her Major Fade Flash Mask, her own brand, she put panthenol in with the exfoliating acids, especially glycolic acid at 15%. The exfoliating acid can be aggressive, but she has been very pleasantly surprised by how many people can tolerate it because of the panthenol, which helps to calm the skin down and allows it to recover. You're exfoliating while recovering, so you're not getting the crazy reaction you'd normally get from a 15% exfoliating acid."

[...] It also has glycerin so it is hydrating in the process, and glycolic acid is a humectant in its own right so it's going to help hold on to moisture. I do it from my head down to my chest and I love it."
What the evidence says.
Independent of what the gurus think, this is what
the published research supports about the main active ingredients here.
Alpha hydroxy acids
Alpha hydroxy acids loosen the bonds holding dead cells at the surface. The evidence supports smoother texture and more even tone over time, and they can leave skin more sensitive to sun.
Ingredients like these draw water into the surface layers and slow how fast it leaves. The evidence is for comfort, softness and hydration rather than for changing the structure of the skin.
