What the gurus are saying
This lightweight gel combines vitamin C and moisturizer in one step, earning praise for the gentler vitamin C form (tetrahexyldecyl ascorbate) that lets you use it morning and night, even with retinol. That simplified routine appeals most to people not already stocked with vitamin C serums or moisturizers. Reviewers would repurchase it, though the product shines if you're trying to pare down steps rather than discovering vitamin C for the first time.

"It's called the Active Seal. This is a moisturizer, which is really interesting because I really enjoyed it. The texture is lovely, and what I really liked is it simplified my routine. Combining a moisturizer with vitamin C just makes so much sense because I was able to use less product. I was able to eliminate a serum from my routine. This is absolutely a product I would buy again, just not right now because I have so many other moisturizers that are open and ready for use."

I Didn’t Repurchase Most of These
"It's called the Active Seal. This is a moisturizer, which is really interesting because I really enjoyed it. The texture is lovely, and what I really liked is it simplified my routine. Combining a moisturizer with vitamin C just makes so much sense because I was able to use less product. I was able to eliminate a serum from my routine. This is absolutely a product I would buy again, just not right now because I have so many other moisturizers that are open and ready for use."
I Let Another Skincare Creator Shop My Shelf
"I have mature skin, I have dry skin, and I love this product. I have been using this every day since I got it. It also contains vitamin C, [...] so her idea is use fewer products that do more things. I like the form factor of this. I love the packaging as well, and I love the squish top. You're going to dispense just a little bit. I don't really think it's a gel, I think it's in between a gel and a lotion, it feels like an emulsion to me, [...] but this is nice, [...] it's very elegant."
Over 50: I Don’t Rebuy Everything I Love
"I really liked the texture and the efficiency. So it's a moisturizer and a vitamin C in one step. And I mean, that makes such good sense. Like, it felt elegant and it was obviously easy. Like, I will definitely buy this again. I'm just not buying it immediately. Like, I have other moisturizers and I have other vitamin C products open and I don't want to duplicate the categories. So, this is more of a delayed, not a dismissed."
I Can't Buy American Products Anymore
"This is Dr. Idriss's Major Fade Active Seal. If I lived in the US it would be a no-brainer, I love this moisturizer, particularly in the summer. It has brighteners for hyperpigmentation and great antioxidant protection, and it is genuinely a fantastic price, but with the import charges I'm not sure I can justify buying it."
"I will use a moisturizer with vitamin C in like the Dr. Idriss Major Fade Active Seal Vitamin C Gel Moisturizer, I've been loving at the moment to protect your skin alongside sunscreen."

Are Dermatologist Skincare Brands Actually Any Good? 🤔 Remedy, Dr Idriss, Prequel
"This is such a good choice as a nice lightweight moisturizer for people of all different skin types and conditions from a [...] dermatologist brand. I [...] like that it has vitamin C Ester to brighten and defend your skin, along with hexapeptide 2 to help with fine lines and glycerin. I think having vitamin C in a step that you already have in your routine like a moisturizer is probably the way I'm going to be using it going forward. [...] It's such a lovely texture and there's no smell to it."
"If you're looking for something a little bit thicker and richer, this is a great option. This is the [...] Dr. Idriss Major Fade Active Seal, it's a moisturizer in a beautiful convenient pump and it's really really really nice on my skin. It does include the THD in there plus it has additional brightening ingredients, so if you're finding hyperpigmentation, you're getting a lot of ingredients in this nice well-rounded moisturizer."
"So I'm talking about tetrahexyl decarbonate for example which is in the Dr. Idriss Major Fade Active Seal. This is a two-in-one vitamin C moisturizer but more than that it also has ceramides and peptides. So it's going to help to strengthen your skin barrier while brightening your skin. So that is one of my favorite ones."

Fall Nighttime Skincare Routine: Face & Body! | Dr. Shereene Idriss
"I love my Active Seal by Pillow Talk because it has vitamin C not in the ascorbic acid form of vitamin C because that you probably would not want to use with the copper peptides from Allies of Skin. It has the ester form of vitamin C, also known as tetrahexyldecyl ascorbate, which you can easily use with copper peptides because it does not get oxidized the same way that ascorbic acid does and it can easily be used with peptides. My motto in life is consistency over intensity."
"The active seal moisturizer [...] has vitamin C, so if I'm using the active seal, I will not use a vitamin C serum because it has enough vitamin C in the moisturizer, which gives me more room for exploration with other serums that can work with vitamin C. So depending on the type of moisturizer that you're using, if you're using moisturizer with actives, make sure that you're not double dipping with the serum game and the actives in your moisturizer."

"Last within the three-step routine is the Active Seal and this is a gel moisturizer which is our vitamin C moisturizer. It's not the active form of vitamin C though, it is tetrahexyldecyl ascorbate, which is the ester form of vitamin C because I want you guys to use this twice a day. Why do I want you to use this twice a day? Because it also has 4-butyl resorcinol, which is also a great tyrosinase inhibitor that does help and make kojic acid and alpha arbutin work better."
Skincare for Your 30s: Anti-Aging, Adult Acne, Oily Skin | Dr. Shereene Idriss
"The Dr. Idriss Major Fade Active Seal Vitamin C Gel Moisturizer is a form of vitamin C known as tetrahexyldecyl ascorbate, which is better geared for people with sensitive skin. If you're somebody who doesn't want to necessarily layer a vitamin C and moisturizer and a sunscreen in the morning, it's a two-in-one, easier, you get it all, it's on the go, and it comes in an airtight container so it doesn't really get broken down at all. That is what I put in the morning."

"It is the cousin form of vitamin C that's not irritating. [...] When you have an inflamed skin barrier and there are free radicals floating around, you have increased reactive oxygen species that come in, go deeper into your skin and want to damage it all and make you more prone to collagen breakdown. So I want to introduce ingredients that are going to help fight all those free radicals to minimize their after effects, aka vitamin C."
How to Prevent & Treat Acne Scars for Brighter Skin! | Dr. Shereene Idriss
"Most vitamin C's on the market come in the form of a serum. This is a vitamin C in the form of a moisturizer. The reason I like it for people who have acne prone skin to minimize discoloration is that it is a gel moisturizer so it is very, very, very lightweight. It's not going to be overpowering but it's still going to be hydrating, and you can use this vitamin C moisturizer up to twice a day. It's not going to be feeling like it's sitting on your face."

Skincare for Your 40s: Anti-aging, Discoloration, & Redness | Dr. Shereene Idriss
"It's not very rich, so if you're very dry, it's not for you. But if you're looking to address discoloration by simplifying your routine with a vitamin C two-in-one, use this one. And if you need just extra hydration, you can add something like SkinCeuticals on top or a basic moisturizer on top to lock it in. Otherwise, this should be enough, especially in a humid climate or as we're going into the summer months. You don't need something so rich on top of your skin."
Best Moisturizers to Soothe & Hydrate Your Skin! | Dr. Shereene Idriss
"I [...] tend to be on the drier part of the spectrum, and it just gets absorbed beautifully underneath your makeup without leaving any swishy residue on top of your skin, and you really don't feel like it's sitting on top of your skin during the day. Overnight I might be supplementing a thicker, richer moisturizer on top of this if the air gets very dry to really get that intense hydration that we all crave in the winter."
