Everywhere you turn, skincare products feature a new trending ingredient, promising the same anti-aging benefits. Though many of these benefits are merely marketing claims, Auro Skincare’s latest trending ingredient is supported by science. “G“, Auro Skincare’s latest antioxidant serum, is powered by glutathione, a master antioxidant clinically proven to improve the appearance of fine lines, wrinkles, and skin tone in just a week.
But what exactly is glutathione, and what makes this secret antioxidant work in skincare? Here’s what founder, Dr. Nayan Patel, PharmD, shared about this exciting new ingredient in antioxidant skincare. Dr. Patel is an internationally recognized expert, consultant, and lecturer on the Master Antioxidant Glutathione and has traveled the world educating practitioners and pharmacists on advanced biochemistry and anti-aging science.
What is glutathione?

“Glutathione is one of the body’s most important antioxidants, but until recently, most people had never heard of it, especially in skincare. Naturally produced in the body, glutathione helps protect our cells from oxidative stress, supports detoxification, and plays a crucial role in immune function. But what makes it exciting in the world of skincare is how it works at a cellular level to help the skin repair, defend, and restore itself, ” says Dr. Patel.
When used in a serum or moisturizer as part of a skincare product, glutathione helps neutralize free radicals that break down collagen and contribute to premature aging. It also supports even skin tone and reduces oxidative inflammation, two major contributors to dullness, irritation, and fine lines. Unlike trendier ingredients offering a surface-level glow, glutathione helps the skin rebuild defenses over time. For this reason, Dr. Patel believes Glutathione could become the next big thing in skincare.
Why use glutathione in skincare products

Despite the intriguing anti-aging benefits of glutathione, it hasn’t been widely used in skincare products. According to Dr. Patel, glutathione hasn’t been used more commonly until now because “It comes down to challenges with stability and effective delivery. Glutathione is a delicate molecule, and effectively getting it into the skin has always been challenging. For years, it was mostly used in IV or oral supplement form to support overall wellness. However, newer delivery methods (like topical technology) have made it possible to stabilize glutathione in topical formats without losing its potency. This means consumers can now get the benefits of glutathione directly where they want them: on their skin.”
Through topical technology, glutathione fights oxidative stress by “Scavenging harmful free radicals and recycling other antioxidants like vitamin C and E. When applied topically in this bioavailable form, it helps reduce oxidative damage and supports the skin’s ability to heal, brighten, and maintain hydration. It’s particularly promising for people dealing with hyperpigmentation, redness, or environmental damage from pollution and UV exposure,” says Dr. Patel.
What the research says

Unlike other skincare marketing claims not supported by the research, scientific interest in glutathione’s role in dermatology is steadily increasing. “A clinical study on G Antioxidant Serum (a topical formulation using stabilized glutathione) demonstrated that it is clinically proven to improve the appearance of fine lines, wrinkles, and skin tone in one week.
“Additional studies have highlighted glutathione’s ability to protect against oxidative stress and support detoxification at the skin level. While more clinical data on topical application is still emerging, what’s already clear is that glutathione is safe, well-tolerated, and works best when paired with other antioxidants in a synergistic skincare routine,” says Dr. Patel. “As more people become aware of oxidative stress and seek out smarter, multitasking skincare solutions, glutathione is starting to get the recognition it deserves. It’s not just another antioxidant; it helps support and regenerate the others. That’s why its potential in skincare is just beginning to unfold and why I believe it will play a much bigger role in the future of healthy aging.”
