We live in an incredible time. We have a world of information at our fingertips, civilians are booking excursions to the moon, and our facility to communicate with others has never been faster or more effective. Call it the apex of human advancement, a time and place where nearly everything seems possible.

One of the biggest boons of our progress is the impact it’s had on skincare. Every day, scientists are learning more and more about our body’s largest organ, identifying what it needs, how it becomes damaged, and what we can do to either maintain or revive our youthful complexions. From non-invasive lasers and using radio frequency to understanding how nature’s ingredients can foster clearer, more radiant skin, we’re truly living in the age of information and discovery.

SesaFlash is just one breakthrough ingredient that’s shown to have a brilliant difference on the quality and elasticity of the skin. Considered a new generation tightening agent, SesaFlash moisturizes and firms with efficacy and speed (as in oh-my-god instantaneity), rendering it one of the hottest new additions to skincare on the market.

But what, exactly, is Sesaflash? And where does it come from?

Sesaflash Defined

In essence, SesaFlash is hydrolyzed sesame protein—that is, proteins extracted from those seeds we sometimes find in our bagels that, while tiny, pack a huge punch of beneficial nutrients.

Chief among them? Fats—as in the good kind. Sesame brims with mono and polyunsaturated fats like oleic, palmitic, stearic and linoleic acid, all of which, Dermaviduals confirms, are essential to replenishing the barrier of our skin, protecting us from sun damage, and leaving us with skin so lustrous there’s no need for Photoshop.

What’s more, sesame—which goes down as the oldest cultivated oil crop—is high in zinc, which promotes collagen production and results in supple, glowing skin.

According to Livestrong, the oils derived from sesame are also rich in Vitamins A and E, both of which contribute to smoother skin and fewer fine lines and wrinkles. Additionally, Livestrong affirms, “sesame oil contains antioxidants and sesamol, which counteract free radicals—a primary cause of aging.”

When sesame protein is hydrolyzed—a process in which natural acids are used to break down water and protein molecules—it creates an extract that hydrates and tightens upon impact.

How Sesaflash Benefits Your Skin

SesaFlash—the result of polymer, galenic and biological research—predominantly affects the topography of the skin, smoothing the orange-peel texture of dry complexions and tightening the loose skin that often comes with aging.

It’s immediately-felt affect is one of the largest draws for both consumers and cosmetics manufacturers. Consider it far from accidental: one of the core attractions of SesaFlash is that it’s clinically tested in vivo—that is, testing that takes place outside of a test tube or petri dish to determine the potency of a product on human participants.

This method is key to understanding how a product genuinely works. As dermatologist and New York Times bestselling author of The Skin Type Solution Dr. Leslie Baumann points out, in vitro testing—a customary technique among skincare manufacturers—means that “the ingredients’ ability to penetrate to the deeper levels of the skin cannot be assessed…in most instances, these ‘in vitro’ results don’t translate to human skin—or treating the beauty concern or skin condition that the product is claiming.”

In vivo outcomes, however, are “always more convincing” because the results are seen first-hand. And what results they are. SesaFlash provides “visible and measurable smoothing of cutaneous relief.”

In other words, the moment this miraculous serum touches your skin, you can see and feel it working through a gentle and moisturizing film that dries quickly and leaves you with baby-soft skin and the unlined complexion of a teenager. 

100% of participants in the in vivo trial—yes, as in all—experienced an immediate tightening of their skin and an enhancement of their appearance, thanks to its ability to lift, firm, hydrate and smooth.
