Protect your complexion against daily stressors while reducing visible signs of ageing with Kiehl's Vital Skin-Strengthening Super Serum, a lightweight anti-ageing serum for all skin types. Targeting fine lines, fatigue and dullness, Kiehl's weightless serum penetrates up to eight layers of the skin's surface to treat ageing caused by everyday aggressors such as pollution and stress. Helping you to achieve a plump and bouncy complexion, the hard-working formula is enriched with Kiehl's smallest form of hyaluronic acid and hydrating glycerin to fortify the skin barrier and lock in moisture. This serum helps reduce the appearance of fine lines, while it boosts radiance by promoting skin surface cell turnover - helping you achieve a youthful glow. Intensely hydrating, Kiehl's Super Serum makes the complexion feel instantly soft and velvety, as it works to make skin resilient, radiant and younger-looking. Why We Love It Kiehl's serum is a definite multitasker; not only does this formula revitalise the skin, it also helps your complexion to feel smooth and soft. And some users even say it's helped to rejuvenate their under-eye area by minimising puffiness and dark circles - yet another way that this serum helps to reduce the appearance of fatigue and premature ageing. Plus, the earthy and refreshing smell also helps you to feel relaxed before you start the day and as you unwind in the evening, as you gently massage the serum into your skin. How To Use It Use in the morning and evening. After cleansing, apply two pumps of the serum to the face and neck, taking care to avoid contact with the eyes. Works Well With Enhance this serum with an anti-ageing moisturiser from Kiehl's collection.
