Kiehl’s clinically-demonstrated serum provides a total skin overhaul. This potent formula penetrates deep into the epidermis and beyond to reduce the appearance of fine lines and wrinkles, while boosting radiance.

You can kiss goodbye to clogged pores, sagging skin, fine lines and wrinkles, and a dull complexion with the Powerful-Strength Line-Reducing Concentrate. Formulated with 12.5% vitamin C, plus ultra-hydrator hyaluronic acid, this efficacious duo collectively firms and locks in moisture while glycerin adds a softening effect. If you want to get your natural glow back (plus everything listed above), this is your golden ticket.

Cleanse skin thoroughly prior to application. Apply serum over entire face twice daily (avoiding the eye area). Can use alone or under your usual moisturiser. In case of contact with eyes, rinse thoroughly.

Note: as the formula blends into the skin, you may experience a feeling of warmth. This sensation is normal.
