iS Clinical C Eye Serum Advance+ is a targeted, clinical-strength eye serum that brings together pure ascorbic acid, sodium hyaluronate, and tripeptide-1 to visibly reduce fine lines, dark circles, and puffiness while defending the delicate eye area against environmental damage. iS Clinical is known for formulating with pharmaceutical-grade actives, and this serum reflects that commitment with a clean, lightweight base that absorbs quickly and layers seamlessly under makeup. It is fragrance-free, making it a comfortable daily option even for those with reactive skin.

Key Benefits

Brightens dark circles and evens tone Ascorbic acid, the purest and most potent form of vitamin C, targets discoloration beneath the eyes and works to create a more uniform, rested appearance over time.

Reduces puffiness and soothes the under-eye area Zinc sulfate helps decongest and calm the under-eye area, while polyporus umbellatus (mushroom) extract provides visible soothing support to tired, stressed skin.

Smooths fine lines and supports firmness Sodium hyaluronate draws moisture into the skin to plump the appearance of fine lines, and tripeptide-1 helps reinforce the skin's natural support structure for longer-term resilience.

Delivers meaningful antioxidant protection Ascorbic acid paired with bioflavonoids works to neutralize free radicals generated by UV exposure and daily environmental stress, helping slow the visible signs of premature aging around the eyes.

Hydrates without heaviness or migration Sodium hyaluronate delivers weightless, deep hydration that sits comfortably on the delicate eye area without migrating onto the eyelid or contributing to puffiness.

If fine lines, crepiness, dark circles, or persistent puffiness around your eyes are your primary concerns, this serum addresses each of them in one focused, twice-daily step. It works particularly well for anyone who spends time outdoors, deals with screen fatigue, or notices that the eye area tends to look tired regardless of how much sleep they get. The antioxidant and brightening actives work together to both repair existing damage and defend against further environmental aging.

The lightweight, fast-absorbing formula suits all skin types, including sensitive and acne-prone skin that cannot tolerate richer eye creams. It will not cause milia, does not feel heavy, and layers cleanly under concealer without pilling. If you have been looking for a clinical-strength vitamin C eye treatment that fits easily into both your morning and evening routines, this is a strong fit.

Because iS Clinical C Eye Serum Advance+ contains ascorbic acid at a clinical concentration and pH, it is especially effective at addressing visible sun damage around the eyes, including brown spots and crepey texture that build up over years of UV exposure. If you use it consistently in the morning before SPF, you are both treating existing damage and creating an additional antioxidant barrier against the environmental triggers that cause it.

Prepare: Cleanse and tone, then allow the eye area to dry completely before applying.

Apply: Dispense 1 to 2 drops into the palm of your hand, then gently pat around the orbital bone using your ring finger. Avoid the eyelid and inner corners.

Frequency: Use twice daily, morning and evening. In the morning, follow with your moisturizer and a broad-spectrum SPF.
