Hydration isn’t just one step in a routine — it’s the foundation everything else is built on. When skin is well-hydrated, it looks plumper, smoother, and more resilient; fine lines soften and your complexion simply looks healthier. That’s the entire premise of Regen4D, a hydration-focused line created by RegenLab, a company with two decades of expertise in regenerative science.
The thread running through every product is 4D Hyaluronic Acid — four molecular weights of hyaluronic acid that sit at different depths of the skin’s surface, so hydration is delivered on multiple levels rather than just sitting on top. The formulas are over 90% natural, fragrance-free, and dermatologist-tested, which makes them an easy fit for sensitive skin.
Below is the full lineup, mapped to the order you’d actually use it — from featherweight serum to rich overnight comfort, plus a weekly treatment to reset. Build the ritual one layer at a time.
HA RegenLift Deep Hydrating Serum
The hero of the line. This lightweight ampoule serum delivers 4D Hyaluronic Acid deep into the skin’s surface to plump and hydrate, helping improve the look of elasticity and soften the appearance of fine lines. Use half an ampoule morning and night, patted into clean skin before your moisturizer.
HA Deep Hydrating Face Cream
A cushiony daily moisturizer that seals in your serum. 4D Hyaluronic Acid pairs with peptides, coffee seed extract, and shea and cocoa butters to nourish, comfort, and leave skin looking smooth and supple. Smooth over the face and neck morning and evening.
HA Deep Hydrating Eye Cream
A fast-absorbing, lightweight cream for the delicate eye area. 4D Hyaluronic Acid, shea butter, and jojoba seed oil hydrate and comfort, while caffeine helps reduce the look of puffiness, dark circles, and fine lines. Tap gently around the orbital bone morning and night.
HA Deep Hydrating Lotion
Take the hydration head to toe. This lightweight face-and-body lotion brings 4D Hyaluronic Acid and peptides to dry, sensitive skin for lasting moisture and a softer, smoother feel — without any heaviness or fragrance. Apply generously wherever skin needs comfort.
HA CellularMask Deep Hydrating Sheet Mask
A once- or twice-weekly treat. This biodegradable full face-and-neck sheet mask is soaked in a 4D Hyaluronic Acid serum that floods the skin with moisture, leaving it looking noticeably more hydrated, luminous, and radiant after a single 15–20 minute session.
Build Your Ritual
You don’t have to adopt all five at once. Start with the RegenLift Serum — it’s the foundation — then layer the Face Cream over it to lock everything in. Add the Eye Cream where skin is thinnest, reach for the Lotion when dryness travels below the jawline, and let the CellularMask be your weekly reset.
The common thread is simple: deeply hydrated skin looks healthier, smoother, and more radiant — and with Regen4D’s 4D Hyaluronic Acid doing the heavy lifting, it only takes a few intentional layers to get there.
