Under-Eye Treatment:
Dark Circles, Puffiness & Fine Lines

When cell turnover slows and skin thins, the under-eye area appears darker, hollowed and crepey.

0.1% Encapsulated Retinaldehyde (Vitamin A)

Supports controlled cellular renewal to improve skin texture and density without irritation.

What you’ll notice over time

Loss of collagen and elastin exaggerates shadows, fine lines and laxity under the eyes.

Collagen Peptides + 10% SNAP-8 (Acetyl Octapeptide-3)

Support skin firmness and visible smoothing by reinforcing collagen signalling pathways.

What you’ll notice over time

Dehydration exaggerates fine lines, shadowing and tired-looking eyes.

Dual-Weight Hyaluronic Acid

Provides both surface hydration and deeper plumping for smoother, more luminous under-eye skin.

What you’ll notice over time

The under-eye area has limited tolerance and reacts quickly to overload.

Multi-Biotics

Support the skin barrier and microbiome balance, improving tolerance and long-term skin quality.

What you’ll notice over time

Dark circles can have multiple causes, often occurring together:

• Pigmentation from excess melanin or sun exposure
• Thin under-eye skin, making blood vessels more visible
• Volume loss, creating hollowing and shadowing
• Poor circulation, often worsened by fatigue or stress

Because causes vary, effective treatment must address more than one pathway.

The under-eye area has the thinnest skin on the face, fewer oil glands, and lower collagen density. It is also in constant motion from blinking and facial expression. These factors make it more prone to dehydration, fine lines, dark circles and loss of firmness over time.

Puffiness is often related to fluid retention, inflammation, lack of sleep, allergies or heavy products that sit on the skin. Occlusive textures can worsen the appearance of swelling over time.

Eye serums and eye creams do different jobs. Eye creams are designed to deliver hydration and occlusion. Eye serums are designed to deliver active ingredients. For dark circles, fine lines, pigmentation and elasticity loss, the active concentration is what changes the skin.

The Restore & Firm Collagen Peptide Eye Serum carries 30 actives including encapsulated retinaldehyde, arnica and vitamin K in a serum format that absorbs without weight. It can be layered under any eye cream if extra hydration is needed, but most users find the serum sufficient on its own.

Retinol can be effective under the eyes, but only when used at the correct dose and delivery system. Free retinol often causes irritation in this area.

Rejuvaus uses 0.1% encapsulated retinaldehyde, designed to release gradually and support renewal with improved tolerance for delicate periocular skin.

Yes. Dehydrated under-eye skin exaggerates fine lines, shadowing and dullness, making dark circles appear more pronounced.

Dual-weight hyaluronic acid in Rejuvaus supports both surface hydration and deeper plumping without heaviness or migration.

Hydration and comfort can improve within days, while visible changes in texture, tone and firmness typically develop over several weeks with consistent use.

By supporting renewal, collagen signalling and barrier health at the same time, Rejuvaus delivers progressive results without cycles of irritation.

Yes. UV exposure contributes to pigmentation, collagen breakdown and thinning skin under the eyes.

Rejuvaus i • Solar Protect & Restore Invisible Zinc Lotion provides mineral UV protection suitable for use around the eye area, helping prevent further darkening and ageing.

Most eye products treat symptoms. Rejuvaus supports the structure, function and tolerance of under-eye skin, allowing visible improvement that lasts.

There's no fixed age. The under-eye skin starts losing collagen density in the mid-twenties and shows the first signs of volume loss, pigmentation or fine lines between late twenties and early thirties depending on genetics, sleep, hydration and sun exposure. Early use of a targeted under-eye serum is preventative rather than corrective. Later use is corrective and takes longer to show results.

Eye Serum is safe for use twice daily from the first sign of concern, including for those new to retinaldehyde.
