When I developed the Trifecta, my initial goal was to create an all-in-one solution to support skin aging at every level.
But when it came to introducing Vitamin C into the formulation, I realized something essential to the process. Vitamin C wasn’t just another trendy skincare ingredient—it was a cornerstone of skin health and a non-negotiable foundation for any routine.
The more I studied Vitamin C, the more it became clear: its power to stimulate collagen, reduce pigmentation, and protect against free radical damage made it indispensable. And yet, I also knew that most Vitamin C serums on the market came with their own challenges and limitations: many were sticky, too harsh for sensitive skin, incompatible with other active ingredients, or fell short with disappointing results, not living up to the hype.
I knew this ingredient deserved more respect and innovation, so I took a step back and made it my mission to figure out how I could maximize Vitamin C's potential, while also eliminating some of its drawbacks.
After years of testing, refining, and formulation work, I came to a surprising conclusion: rather than forcing such a complicated ingredient into an already-complex formula, I developed Quench as a standalone Vitamin C product.
Quench is a next-generation antioxidant skincare solution designed to outperform traditional Vitamin C while being tolerated by even the most sensitive skin types. Quench is unlike any other Vitamin C serum on the market, and it's not just another step in the KaramMD Trifecta—it’s one of its three foundational pillars. It plays a critical role in the system, and it’s a must-have serum for anyone serious about long-term skin health.
Here’s why it belongs in your routine.
Every ingredient in Quench was chosen for one reason: it works. Together, this unique formulation creates a potent yet gentle serum that delivers meaningful, lasting results.
Quench features not one, but three forms of Vitamin C (Magnesium Ascorbyl Phosphate, Aminopropyl Ascorbyl Phosphate, and Tetrahexyldecyl Ascorbate) which were carefully selected for their effectiveness and stability.
These advanced, non-acidic forms of Vitamin C are known to penetrate deeply and stimulate cellular turnover, which enhances skin brightness over time. By suppressing excess melanin production and increasing radiance at the surface, this combination visibly improves dull, uneven skin and restores your natural glow without irritation.
Discoloration caused by aging, sun exposure, or hormonal changes can be stubborn—but Quench addresses this concern at multiple levels.
Licorice Root Extract helps block tyrosinase, the enzyme responsible for melanin production, while Green Tea offers antioxidant benefits that calm irritation and reduce the risk of post-inflammatory hyperpigmentation. These work in harmony with Vitamin C to fade the look of dark spots, sun spots, and melasma, resulting in a clearer, more even complexion over time.
Vitamin C is a critical cofactor in collagen synthesis, helping the skin repair and rebuild its structural support.
Quench amplifies this benefit with Panthenol (Vitamin B5), which further promotes cell regeneration and elasticity. This combination works to visibly improve firmness, reduce the appearance of fine lines, and help skin feel stronger, more resilient, and lifted—making it a key ally in any anti-aging regimen.
Hydration is essential to youthful, healthy-looking skin. Quench delivers multi-level hydration with Sodium Hyaluronate, a smaller-molecule form of Hyaluronic acid that draws water deep into the skin, and Trehalose, a sugar molecule that helps retain moisture and protect against dehydration.
These are complemented by Castor Oil and Aloe Vera, which seal in moisture and soften skin texture, leaving it smooth, plump, and comfortable all day long.
Quench provides comprehensive defense against environmental stressors through its powerful antioxidant blend. The three forms of Vitamin C work synergistically with Ziziphus Spina-Christi (a desert botanical with potent repair capabilities), Vitamin E (a lipid-soluble antioxidant that fortifies the skin barrier), and Green Tea Extract (a polyphenol-rich ingredient that neutralizes UV-induced damage).
Together, these shield the skin from oxidative stress, pollution, and free radicals—preserving skin health and preventing premature aging.
Sensitive and reactive skin often struggles with inflammation, redness, or breakouts. Quench was specifically formulated to calm and rebalance the skin using soothing botanicals like Willowherb, Aloe Vera, and Green Tea.
These ingredients are rich in flavonoids and soothing compounds that help reduce visible irritation, support barrier recovery, and keep the skin looking calm, even, and refreshed—making it ideal for all skin types.
Unlike many Vitamin C serums that feel sticky, tacky, or harsh on the skin, Quench is formulated to provide a smooth, fast-absorbing, and dewy finish without residue.
It contains no ascorbic acid—the common culprit for stinging and oxidation—making it well-tolerated by all users. The lightweight texture layers seamlessly under moisturizers, sunscreens, and makeup, and is compatible with powerful actives like retinol. This elegant formula transforms your routine into a skincare experience you’ll look forward to every day.
When we talk about skin transformation, it’s not just about looking better—it’s about feeling better in your own skin. That’s what Quench delivers.
Its recent recognition being voted Best Vitamin C Serum by AskMen's Grooming Awards, is a reflection of how powerful and versatile this formula really is.
"Picking a favorite product from KaramMD’s extensive skincare line was extremely difficult, as we were fond of everything (especially its signature green tea scent) but this vitamin C serum with three stable forms of the powerful skin-boosting ingredient took home the cake. It’s also dewy and manufactured for sensitive skin, so feel free to douse it around eyes, lips, or whatever area is in desperate need of a little rejuvenation. -AskMen Grooming Awards
