I have a tiny bit of tech neck. Most people have never looked for it.
It’s the horizontal line — sometimes two — across the front of your neck. You get it from looking down. When you put your sunscreen on, where does your hand stop? Mine stopped at my jaw. For years.

- Helps brighten, firm, and strengthen the skin barrier
What customers say about the Defend Derm Duo.
Love this!
“I used to buy the higher priced brand from my facialist. It works the same and with the price point, I can use a bit more for my neck, chest, and hands!!”
Love it!!!
“This really lightens up the dark spots! It work’s! I use it on my face,neck,chest and hands!”
Happy!
“Liked it enough to reorder! I had been considering a vitamin C serum for awhile but resisted due to cost. Brandefy was in my price point, and I do believe my skin is brighter and overall skin tone is improved. If you are considering it’s worth a try!”
Do you have Tech Neck?
Tech neck comes from one motion, repeated a few thousand times a day. The same skin folds along the same line.
That skin is built differently from your face. It’s thinner. It has fewer oil glands, so it dries out faster and stays dry longer. It starts out with less collagen and elastin. And facial skin is anchored down to muscle and bone in a way neck skin is not — there’s less underneath it, holding it where it is.
Your face doesn’t end at your chin.
You’ve probably been putting vitamin C on it for years. Your neck is the same skin — thinner, fewer oil glands, less collagen to start with — and your routine stops at the jaw.
Not just because you forgot. A good vitamin C serum runs $185 an ounce, and at $185 an ounce you use it like it’s $185 an ounce — carefully, and only where you’re sure it counts. The cream that goes with it is another $155.
Brandefy’s Defend Derm Duo bundles those two steps at a much more affordable price. The serum is inspired by SkinCeuticals C E Ferulic. The cream is inspired by SkinCeuticals Triple Lipid Restore. Both full size.
Same two steps. Same two sizes, bottle for bottle. $244 apart.
Our Vitamin C serum is the same three actives at the same 15% L-ascorbic acid. Our Tri Lipid cream also contains three barrier lipids at comparable levels. We work with the same chemists and manufacturers that supply other prestige brands, and we sell it to you directly instead of through a counter.
Brandefy’s Tri Lipid cream helps strengthen skin with a blend of 1.5% ceramides, 4.0% pomegranate sterols, and 1.8% fatty acids. This combination helps firm, restore, and reinforce the skin barrier for a smoother, more youthful appearance. With consistent use, it delivers a stronger barrier, fewer dry patches, and calmer, supported skin.
Pair it with our Vitamin C to minimize the appearance of fine lines and wrinkles, fade dark spots, and repair the skin barrier.
Two steps. Both of them go past your jaw.

About these two panels: questions asked whether respondents noticed a change in their skin, and the panels did not record where on the body the product was applied. The Tri Lipid panel ran 81 responses and 71 are counted here — ten excluded, being one internal staff test and nine people who said they were not currently using the product. All 48 Vit C responses are counted.

Questions
How far does one jar go?
It depends on how much skin you’re covering and how heavy-handed you are. This is a heavy cream, so a thin layer rather than a scoop, and roughly as much again takes you from jaw to collarbone.
The jar is 48 mL — the same size as the $155 one. Taking it down your neck and chest uses more of it than stopping at the jaw would. That’s the point of buying this one.
Can I use it on my chest too?
Yes. Both steps. I take mine from the jaw down to the top of the neckline. Your décolletage is built the way your neck is — thin, dry, and out in the sun all day.
Which one goes on in the morning and which at night?
Vitamin C serum in the morning, under your sunscreen. The Tri Lipid cream at night, as the last step. If you run dry you can use the cream in the morning as well — plenty of people do.
My skin is sensitive. Where do I start?
Start with one of the two, not both, and go every other day before you go daily. Neck skin is thinner than facial skin, so it’s a reasonable place to be cautious.
Skin there can react when your face doesn’t. Always perform a patch test before using new products. Discontinue if irritation occurs.
