The Ultimate Eye Opener: Meet the New AC⁺ Eye Serum

If there is one question that we hear on repeat at our Chelsea clinic it’s “How do I actually fix tired-looking eyes?” It’s a fair question considering the skin surrounding our eyes is up to four times thinner than the rest of the face, it possesses fewer oil glands, undergoes thousands of micro-expressions a day and is the very first area to betray a poor night’s sleep, seasonal allergies, or structural changes over time. But because this skin is so thin, it also gets irritated incredibly easily.

That is exactly why Sarah created the new AC⁺ Eye serum. Built on years of hands-on clinic experience and real science, this latest targeted formula will transform how you treat hard-to-tackle eye concerns. It is the newest addition to our award-winning Clinic Range, giving you noticeable brightening, smoothing, and tightening results while being incredibly gentle on your skin. Here is a simple look at the science, the ingredients, and the technology that make AC⁺ Eye a total game-changer for your daily skincare routine.

Clinic-level care at home

Sarah has spent decades analysing skin up close in the Clinic, giving her a deep understanding of the exact eye concerns clients face daily. She knows that they aren’t just dealing with one isolated issue; they want to tackle shadows, line, and puffiness all at once. This formula is the direct result of that hands-on experience, combining her practical knowledge of what real skin needs with the most advanced skincare science.

“With AC⁺ Eye, I bring the same level of clinical precision and performance we achieve with our clinic face serums to a targeted solution for the eye area,” she says. “It’s a next-gen formulation that delivers powerful results while respecting the skin’s natural integrity in the most delicate areas of the face.”

Mixing Retinal and Vitamin C safely

Historically, mixing Vitamin A (Retinol) and Vitamin C in one product was a nightmare for chemists. Usually, these two ingredients need different environments to stay stable and mixing them together in high strengths could often result in redness and irritation, especially around the eyes where the skin is thinner and more prone to sensitivity. AC⁺ Eye avoids this by combining a highly- stabilised form of Vitamin C (Hydro-C) and encapsulated Retinal into one powerful formula that delivers potent results without any barrier disruption.What’s more, it pairs up some of the most-studied and scientifically-proven active ingredients that actually help each other work harder instead of overwhelming skin. Here are the AC⁺ Eye ingredient power pairs to know…

The Restructuring Duo: Retinal & EGF Growth Factor

Retinal: Retinaldehyde (aka Retinal) is the most potent form of Vitamin A available without a prescription. It sits just one metabolic step away from retinoic acid, meaning it works up to 11 times faster than standard retinol. In this formula it accelerates cellular renewal and coaxes fresh, healthy skin cells to the surface, rapidly smoothing out fine lines and wrinkles.
EGF (Epidermal Growth Factor): Growth factors are cellular messengers that signal your skin to repair itself. Combined with Retinal, they boost natural collagen and elastin production to firm up thinning skin and lift the eye area.

The Radiance & Defense Duo: Hydro-C & EGT Amino Acid

Hydro-C (Vitamin C): Tiredness and daily pollution can cause dark shadows and dull skin around the eyes. This water-soluble, highly-stable form of Vitamin C targets melanin production (which can dull and darken skin) to brighten hyperpigmentation.
EGT Amino Acid: This is a strong antioxidant that protects your skin from pollution and blue light, keeping the eye area looking fresh. EGT also acts as a support system for Vitamin C. Once Vitamin C neutralises a free radical, it degrades. EGT steps in to donate electrons and recycle the spent Vitamin C back to life. This continuous loop boosts formula stability and stretches the lifespan of Vitamin C for maximum brightening and anti-ageing power.

Getting the ingredients into the skin

An exceptional formula is entirely useless if its active ingredients can’t reach their destination. Because the skin barrier is designed to keep external elements out, heavy (or large) skincare molecules often sit idly on the surface of the skin, evaporating before they can do any real work. To overcome this, AC⁺ Eye is powered by the Clinic Range’s exclusive deep-delivery ingredient system (TTS³). Here’s how it works…

Precision encapsulation

Encapsulation is when potent actives are wrapped in microscopic, bio-available ‘bubbles’. These ‘bubbles’ act like a GPS, carrying the retinal, vitamin C, and growth factors in this formula, safely past the skin's surface and releasing them exactly where they need to go, essentially ensuring the ingredients work better without disrupting the skin barrier on the surface.

A biomimetic lamellar base

AC⁺ Eye serum has also been formulated to have a skin-mimicking base structure. This lamellar emulsion (the base structure) mirrors the natural lipid architecture (the oils) of your own skin barrier. Because your skin recognises the formula as identical to its own lipid structure, it instantly welcomes the serum to do its job. This structural harmony - coupled with our encapsulation technology and synergistic ingredient pairing - results in a massive statistical leap in performance with up to 12 times more actives transported to exactly where they’re needed and up to 20 times the efficacy. Best of all? It’s all achieved with minimal irritation, ensuring your skin’s vital moisture barrier remains completely uncompromised.

What you will see…

The best part about this formula is that it gives you instant results while simultaneously working on deeper issues over the long term.

Right Away

The sensorial experience starts the moment you use it as the tube has a built-in, cooling ceramic tip that immediately calms puffiness and refreshes skin as you glide it under your eyes. As for the serum, it has a featherlight hydro-serum texture that absorbs effortlessly without a trace of greasy residue. It floods the area with moisture delivering instant luminosity and a perfectly smooth, plump canvas that allows concealer to layer seamlessly over the top without pilling or creasing.

Need proof? All of these benefits are backed by our clinical tests. In fact, in just 15 minutes, skin appeared 19.8% more radiant, while after a single application the depth of wrinkles and lines around the eyes was reduced by 8% and skin smoothness improved by 4%. Consumer testing was equally impressive with 100% of participants saying their eye area looked instantly brighter and more refreshed, 100% noticing reduced puffiness immediately after use, 93.3% saying their skin looked smoother straight away and 100% agreeing the formula sat perfectly underneath makeup.

Over Time

Consistency is always key for any skincare formula so, as you keep using AC+ Eye, you’ll see more pronounced results as your skin cells begin to renew. Expect deep lines to soften, skin to feel firmer and dark shadows to fade so you look like you’ve had a perfect eight hours of sleep.

How to use AC⁺ Eye

To get the best results, use AC⁺ Eye every morning and night and as part of your everyday routine.

Prep: Dispense a small amount of serum onto the cooling ceramic applicator after cleansing.

Apply: Sweep the applicator gently around the entire eye contour. Start beneath the eyes, moving out toward the crow’s feet area and up across the brow bone.

Absorb: Use your ring finger to gently tap any excess product into the skin until it’s completely absorbed. Don’t pull or tug your skin.

Layer: For those looking to tackle advanced, deep-set eye concerns, Sarah recommends pairing AC⁺ Eye serum with our iconic Eye Recovery cream. You can layer AC⁺ Eye underneath Eye Recovery as a supercharged primer, or alternate your routine by using AC⁺ Eye in the morning for lifting and brightening, and Eye Recovery at night for intensive nourishment and regeneration.

How to add it to your routine

If you already have a skincare routine you love, stick to what works and add in our new AC⁺ Eye after cleansing. But if you’d like to follow our skin-health focused routine, here is our step-by-step guide:

Step 1: Cleanse with Ultimate Cleanse

Massage the balm into dry skin to dissolve makeup, oil and impurities at night and to refresh and stimulate skin in the morning. Emulsify with water and rinse to ensure your skin is completely clean, balanced, and perfectly primed to absorb the active ingredients that follow.

Step 2: Target with AC⁺ Eye serum

Next, focus on the delicate eye area. The cooling ceramic applicator instantly depuffs and stimulates microcirculation.

Step 3: Treat with your preferred serum

Tailor your treatment to target specific skin concerns. Apply C¹ or C² Vitamin C Power Serum in the morning to brighten and boost antioxidant protection and A¹ or A² Vitamin A Power Serum at night to target fine lines, a loss of firmness and other signs of ageing.

Step 4: Lock in goodness with a moisturiser

In the morning, smooth on Dynamic Defence Concentrate Moisturiser for vital hydration layered underneath your favourite Skin Insurance SPF to provide full protection against daily UV damage. For your evening routine, layer on Overnight Facial or Icon Night Smartsome™ A³ X50³ Cream to support the skin's natural repair cycle overnight. This final step locks in moisture, strengthens the skin barrier and reinforces a lit-from-within glow.
