SKIN TYPE: Mature Skin / With the Kiehl’s Age Defender Power Serum, the signs of skin ageing are reduced and men's skin is strengthened and tightened. The firming serum for men reduces fine lines, wrinkles, as well as signs of fatigue and ensures a fresh and healthy-looking complexion. The care specifically suitable for mature men's skin contains valuable active complexes that strengthen and firm the declining power of cell structures with concentrated cypress extract. As a result, the skin appears firmer and more youthful, regaining its natural radiance. The ingredients contained in the formula are mostly of natural origin, providing care that is suitable for all skin types. In addition, the ultra-light anti-age serum is quickly absorbed without leaving a film that would weigh down the skin. With regular use of Kiehl’s Age Defender Power Serum, there is a tangible and visible improvement in skin quality as well as refinement of pores. At the same time, the skin is deeply hydrated, strengthening the skin barrier, preventing harmful external influences from penetrating the skin, and maintaining the natural moisture balance.
