Rated 4.8/5 • Excellent
What does Damage Control actually do?
It's our ceramide barrier moisturizer. Three ceramides, NP, AP, and EOP, rebuild the skin's outer barrier while Squalane and Sodium Hyaluronate hold moisture in all day. If your skin feels dry, tight, or flaky by noon, this is the fix for that.
Does it feel heavy or greasy?
No. It's a cream, so it's richer than a lotion, but it absorbs clean without a greasy film. Fragrance-free too, so it doesn't fight with your cologne.
When does it go in my routine?
Last. Cleanse, serum, then a pea-sized amount of Damage Control on slightly damp skin, AM and PM. SPF goes on after it in the morning. At night it's the final layer, it seals your serums in.
Who's it for?
Anyone whose skin runs dry, tight, or flaky, and anyone whose face stings after a shave. It's also the recovery step if you use retinol or acids. On Smooth Criminal nights, this goes on right after.

We gave the other guys a few wins.
Every brand's comparison chart has them winning all five rows. That's why they're worthless. So here's an honest one. Where the other guys actually beat us, we said so. You decide if the things they're winning are the things that matter.

We Didn't Run These Studies.
That's the Whole Point.
Every brand waves around its own "clinical trial." We're not going to insult you like that.
These numbers come from independent, published research on the actual ingredients we build with, Copper Peptide, Niacinamide, Ceramides. Nobody paid for the outcome.

Maxxing makes skincare, supplements, and tools for people in their 20s to 40s who want results without a complicated routine. Copper peptide and vitamin C serums, collagen and creatine, jawline tools. Everything is here because the ingredient actually does something, not because it rounds out a shelf. You end up with a short routine you'll actually keep up with.
We pick ingredients with real backing, dose them at a level worth taking, and leave the filler out. Most routines fail because they ask for ten steps nobody sticks to past week one. Ours are short on purpose, because the routine you keep beats the one you abandon. Use it consistently and it works.
GHK-Cu is our copper peptide serum. It supports the look of younger, tighter, firmer skin, and it's one of our most popular picks for anyone focused on skin quality and a more refined appearance over time. If you want one serum to start with, this is the one most people reach for.
Most people use their stack for several weeks before they notice a change, and the skin and recovery benefits keep building with daily use. Consistency matters more than intensity. The people who see the most aren't pushing harder, they're just sticking with it. Results vary from person to person.
Our formulas use ingredients recognized in the skincare and wellness community. As with anything new, patch-test the serums first, and check with a healthcare professional before starting if you have a medical condition or take medication. These statements haven't been evaluated by the FDA, and our products aren't meant to diagnose, treat, cure, or prevent any disease.
A subscription ships your stack on a schedule you set, so you don't run out, usually at a lower price than a one-time order. You can pause, skip, or cancel anytime from your account. There's no lock-in, and stopping costs you nothing.
Try it for 30 days. If it isn't working for you, email our team and we'll sort out a refund or replacement. We'd rather you stop than keep something you're not happy with.
