WHY MEN OVER 50 NEED THIS

🧬
Collagen drops 1% every year after 30

The eye area has the thinnest skin on your face — it loses firmness faster than anywhere else, making bags and wrinkles appear sooner.

😴
Poor circulation causes dark circles & puffiness

Sluggish blood flow causes fluid buildup and discolouration under the eyes — caffeine directly targets and reverses this.

💧
Men's skin loses moisture faster with age

Testosterone decline reduces natural oil production — hyaluronic acid restores hydration and plumps fine lines from within.

Key Ingredients

- Caffeine 5% (Coffee Extract) reduces puffiness and eye bags by constricting blood vessels and draining excess fluid from the under-eye area — delivering visible depuffing results fast.

- Teapolyphenols (Green Tea Extract) neutralises free radicals that accelerate under-eye aging, reduces inflammation that causes puffiness and strengthens the thin capillary walls responsible for dark circles.

- Dipotassium Glycyrrhizinate (Licorice Root) brightens dark circles and visibly reduces discolouration by targeting inflammation and pigmentation directly beneath the surface of the skin.

- Hydroxyethyl Urea deeply hydrates the delicate under-eye area by drawing moisture into the skin and locking it in — plumping fine lines and restoring a smoother, fuller look without irritation.

What Results Can I Expect?

Results may vary for each individual. However 96.5% of our customers are satisfied with the product's effects under eyes. 93% said it was the first product they ever tried that actually worked.

Interestingly, what many of our customers notice first is reduced puffiness and brightened dark circles. Most report it after just 4 days. With results only getting better with more consistent use.

How To Use?

Using the Caffeine Booster Serum is simple and takes under 30 seconds.

Dispense 2-3 drops onto your fingertip and gently pat the serum under each eye using your ring finger. The ring finger applies the least pressure — ideal for the delicate under-eye area. Allow to absorb fully before applying anything else.

For best results:

  • Use daily, every morning and evening after cleansing
  • Apply to clean, dry skin
  • Use your ring finger only — never rub or drag
  • Allow 60 seconds to fully absorb before applying other products

Repair Your Under Eye Skin

The Problem: Are you tired of hearing "You look exhausted" all the time? The area under your eyes reveals the truth — a restless night or demanding day shows on your face by morning. For men over 50, this only gets worse as skin thins and loses its ability to recover.

The Solution: Zentifel's Caffeine Booster Serum penetrates deep into the delicate under-eye area, delivering concentrated active ingredients that visibly reduce puffiness, fade dark circles and restore a fresher, sharper appearance.

The Formula: Powered by 5% Caffeine to constrict blood vessels and drain excess fluid, Teapolyphenols to neutralise inflammation and brighten discolouration, and Hydroxyethyl Urea to deeply hydrate and plump — three ingredients that work together to tackle every visible sign of under-eye aging.

How The Caffeine Booster Eye Serum Works

Why Your Eyes Need This: Tired eyes showing dark circles, puffiness and fine lines? These concerns stem from poor circulation, fluid retention and thinning skin in the delicate under-eye area. The solution lies in delivering concentrated active ingredients directly into the skin where they can work at the source.

What Makes It Powerful: Our Caffeine Booster Serum gives men a fast and effective solution for reducing eye bags, dark circles and under-eye aging. Powered by 5% Caffeine to constrict blood vessels and drain excess fluid, combined with Teapolyphenols to neutralise inflammation and brighten discolouration — targeting every visible sign of under-eye aging.

Results You'll Feel Fast: Once applied the formula gets to work immediately. Caffeine constricts blood vessels to minimise dark circles and reduce puffiness. Teapolyphenols neutralise the inflammation causing discolouration while Hydroxyethyl Urea draws deep moisture into the skin — plumping fine lines and keeping the under-eye area smooth and refreshed.
