As we age, our skin cells die faster than we can replicate them. Fortunately, plant stem cells present a unique advantage: the ability to not only protect or repair but to actually replace these lost or damaged cells with healthy, differentiated new cells.
The applications of plant stem cells are wide ranging, from anti-aging to anti-acne. Here, we present a few newer and lesser-known plant stem cells that are changing the face of skin care.
Common lilac (Syringa vulgaris L.) is showing new promise in fighting acne. This acid-stable antioxidant has demonstrated the ability to inhibit 5α-reductase, an enzyme involved in sebum production, while decreasing the pro-inflammatory chemokine IL-8. In a clinical study, a 1% plant stem cell extract applied twice daily for 30 days reduced acne lesions by 40% and decreased inflammation and pigmentation. Rich in verbascosides, common lilac is ideal for acneic skin with inflammatory lesions.
From the sea, several new plant stem cells have emerged to affect the way we treat skin lightening and collagen generation. Fringing France’s Brittany Coast, sea fennel (Crithmum maritimum callus culture filtrate) has the ability to regenerate itself despite the extreme temperatures and harsh conditions of its environment. In our skin, this adaptogenic benefit translates into the ability to repair pigment damage as well as heal the skin and regulate cell turnover. DermaQuest’s Stem Cell 3D Complex uses sea fennel stem cells for brightening, anti-aging and skin renewal along with Edelweiss stem cells for skin regeneration and Gardenia stem cells, which contain skin-firming and smoothing ferulic acid.
Another seashore plant native to Europe, sea holly (Eryngium maritimum) features plant stem cells that strengthen the Epidermal Dermal Junction (EDJ), thereby boosting epidermal cell activity, skin firmness, hydration and texture. In vivo tests support the cosmetic claims that include firming, revitalization, moisturization and skin texture improvement. In addition to normalizing cell differentiation and reducing photo-induced inflammation, this drought-tolerant plant’s active may also help improve collagen synthesis by 34%.
DermaQuest incorporates all three plant stem cells−sea fennel, gardenia and sea holly−in its Stem Cell 3D Eye Lift to lift, firm, hydrate, brighten and smooth the delicate skin around the eye.
The plant kingdom’s rich bevy of stem cell botanicals exhibit great age-defying qualities that allow our skin to better cope and thrive in the face of both intrinsic age factors, such as slower cell replication, and extrinsic factors, including ultraviolet damage. All together, these newest offerings bode great promise for skin care.
