Will this actually change my jawline?
Not the bone, no, and anyone who tells you a stone will is selling you something. What it works on is everything sitting on top: puffiness, fluid, and the tension your jaw holds. Sweep outward and upward every day and the contoured, de-puffed look shows in the mirror, especially in the morning. Skip a week and it fades, so this is one of those things consistency decides.
How do I use it?
Apply a few drops of serum or moisturizer first so the stone glides instead of drags. Hold it almost flat, 15 to 30 degrees, and sweep outward and upward: chin to ear along the jaw, nose to ear on the cheekbones, then forehead and neck. Five to ten strokes per area, 3 to 5 minutes total. Daily matters more than hard, light pressure done every day beats a deep dig once a week.
Why does everyone say to put it in the fridge?
Because cold stone is the fastest de-puff you'll get out of this. Ten minutes in the fridge before you use it and the morning-puffiness difference is obvious the same day. If you want cold on demand without waiting, it pairs well with the Cryo Roller, the Sculptor shapes and releases tension while the roller handles the cold therapy.
Do I need a serum or oil with it?
Yes, something slippery, or the stone drags on dry skin instead of gliding. Any serum or moisturizer you already use works, a couple of drops is enough. If you're using Glow anyway, do the strokes right after you apply it and the tool rides on top. No need to buy anything extra for this.

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.
