Being a beauty blogger has its perks: for one, you have to try lots of products! Of course, being a beauty blogger also has its detriments: you have to try lots of products, and some of these products are not always good for my normal, but somewhat sensitive, skin.
That's why I was happy to come across the Skin Scientifica T'Fivve line, which claims to be "perfect for those who are ready for an anti-aging regimen, but are hesitant to use existing products because of skin sensitivity to traditional ingredients. Instead of the typical anti-aging ingredients, the T'Fivve line largely depends on hydration systems, vitamin C, peptides, and K6PC5, an ingredient the company deems "a skin...activator that reduces the appearance of fine lines and wrinkles." Although research on K6PC5 seems extremely limited (only research conducted by the company itself could be found), K6PC5 reportedly activates the keratinocyte (skin cell) differentiation, fibroblast proliferation, and collagen synthesis without irritating the skin. Best of all, the company claims that K6PC5 is not deteriorated by light or heat, like many antioxidants. However, one should keep in mind that I could not find whether the studies on K6PC5 were double-blind, placebo-controlled, multi-center, split-face, etc.
Of all the Skin Scientifica products, my favorite is the T'Fivve Anti-Aging Eye Repair Serum ($65.00, SkinScientifica.com). The cream features K6PC5, undereye-brightening and firming niacinamide in relatively high concentration, antioxidant vitamin C and firming peptides as ascorbyl pentapeptide, and a very hydrating complex with a largely silicone base. The cream leaves skin feeling smooth, and a relatively high concentration of silica particles gives the undereye area an instant cosmetic sheen. Because T'Fivve Anti-Aging Eye Repair Serum takes a few minutes to dry on the skin, I personally like to apply the eye cream, brush my teeth, and then put make-up on the undereye area. It leaves the area cool and smooth.
Over time, with the skin-firming, hydrating, and antioxidant properties of T'Fivve Anti-Aging Eye Repair Serum, this repair serum can help to prevent future signs of damage from occurring. Are there better, more potent eye creams out there? Certainly. However, the strength of T'Fivve Anti-Aging Eye Repair Serum is that it is gentle enough for sensitive skin, but still tough enough to fight free radicals, dryness, dullness, and future loss of firmness for those patients. I give it a solid 9/10. (High concentration of well-researched ingredients: 3/3. Unique formulation or new technology: 3+/3. Value for the money: 2.5/3. Sunscreen: 0.5/1, with a deduction of only -0.5 because this eye serum may be desirable to use at night as well.)
