Life Extension offers an oral supplement to help protect against harmful solar radiation. During a decade of clinical trials, FernBlock® has shown remarkable effectiveness in shielding skin against dangerous ultraviolet exposure.39-44 Studies have shown that this fern extract has a high affinity for skin tissue and helps protect against ultraviolet damage shown to cause premature skin aging and wrinkling.45,46
FernBlock® is a natural extract derived from the fern plant Polypodium leucotomos. Used as a sunburn remedy by native Indians for centuries, this natural fern extract has been formulated by international scientists affiliated with leading institutions.

This product has been upgraded to contain Sendara™, a patented blend of the herbs ashwagandha and Indian gooseberry. It is rich in flavonoids and steroidal lactones called withanolides, which are thought to have a number of beneficial properties. Ashwagandha works as an adaptogen to enhance the body’s ability to respond to stress, which is thought to be a major contributor to physical signs of aging and that can exacerbate or trigger certain skin conditions. This adaptogen specifically targets excess cortisol release triggered by stress. Indian gooseberry is an antioxidant that helps prevent oxidative stress and degradation of skin proteins and may enhance the firmness of skin.49,50
Sendara™ combines these two ingredients into one anti-aging cosmeceutical. In addition to providing stress relief for the skin, Sendara™ also offers skin benefits, in terms of skin appearance, by inhibiting the enzyme that cleaves and damages collagen, a primary structural protein of the skin. Sendara™ also helps in retaining skin moisture by inhibiting the enzyme hyaluronidase.49,50
FernBlock® is designed to complement topical sunscreens for intense sun exposure. Topical sunscreens are effective if properly and regularly applied, especially for long periods of sun exposure. FernBlock® supplements the effects of sunscreens by protecting the entire skin surface and has an obvious advantage since it cannot be removed by perspiring or bathing. |
