When it comes to skincare, we often hear about heavy hitters like hyaluronic acid, vitamin C, and niacinamide.
But there’s another lesser-known ingredient quietly making waves in the beauty industry: glycine, that you may have noticed before in your skincare's ingredients list. But what exactly is glycine? This humble amino acid plays a crucial role in maintaining healthy, glowing skin.
Let’s explore how glycine works, why it matters, and how you can incorporate it into your skincare routine.

What is Glycine?
Glycine is the smallest and simplest amino acid, often referred to as a building block of proteins.
Found naturally in our bodies, it plays a significant role in collagen production—a protein that gives our skin its structure, elasticity, and firmness. Glycine isn’t just beneficial internally; its topical application in skincare products has shown impressive benefits for maintaining healthy skin.
As one of the non-essential amino acids, glycine is produced by the human body. However, supplementation—whether through diet or skincare—can amplify its benefits. It’s involved in various biological processes, including protein synthesis, tissue repair, and even antioxidant support. Glycine’s multi-functional nature makes it a critical player in your skincare formulations to help achieve glowy and clearer skin.
Benefits of Glycine in Skincare
Boosts Collagen Production
Collagen is essential for youthful, firm skin, but its production declines as we age. Glycine supports the synthesis of collagen, helping to improve skin’s elasticity and reduce the appearance of fine lines and wrinkles.
Enhances Skin Barrier Function
A healthy skin barrier protects against environmental stressors and retains moisture. Glycine helps strengthen the skin barrier, reducing transepidermal water loss (TEWL) and keeping your skin hydrated.
Soothes and Calms the Skin
Glycine’s anti-inflammatory properties make it an excellent ingredient for sensitive or irritated skin. It helps to reduce redness and calm inflammation caused by environmental stressors or skin conditions.
Hydrates the Skin
As a natural humectant, glycine attracts water to the skin, ensuring it stays hydrated and plump. This makes it an ideal ingredient for dry or dehydrated skin types.
Protects Against Oxidative Stress
Oxidative stress from pollution, UV radiation, and other environmental factors can accelerate skin aging. Glycine’s antioxidant properties help combat free radicals, protecting the skin from premature aging.
How to Use Glycine in Your Skincare Routine
Look for Glycine in Formulations
Glycine is commonly found in moisturizers, serums, and cleansers. Look for it in the ingredient list, often labeled as glycine or part of collagen-boosting complexes.
Combine with Complementary Ingredients
For enhanced benefits, pair glycine with ingredients like hyaluronic acid for hydration, niacinamide or peptides for barrier repair.
Consistency Is Key
To see visible results, incorporate glycine-infused products into your daily routine. Use them morning and night for optimal benefits.
Eating Your Glycine
We’re all about eating your skincare. Glycine isn’t just an ingredient for topical products—it’s naturally present in many foods that can benefit your skin from the inside out. Incorporating glycine-rich foods like gelatin, bone broth, poultry, fish, and soy products into your meals can provide:
Enhanced Collagen Production: Supporting skin elasticity and reducing fine lines.
Improved Hydration: Helping your skin retain moisture naturally.
Calmer, Soothed Skin: Thanks to glycine’s anti-inflammatory properties.
Protection Against Aging: Combatting oxidative stress for a youthful glow.
Try adding a warm cup of bone broth to your daily routine or enjoy dishes made with gelatin for a tasty and skin-loving boost.
Our skin is often a reflection of our diet. By consuming glycine-rich foods, you’re not only benefiting your skin but also supporting overall health. Glycine contributes to gut health, muscle repair, and even sleep quality—all of which play a role in maintaining a radiant complexion.
For vegetarians or vegans, glycine can also be found in plant-based sources like legumes and seeds. Supplements are another option, ensuring you get enough of this vital amino acid to reap its full benefits.
Glycine Beyond Skincare
While glycine is a star in the world of skincare, its benefits extend far beyond. It’s a key component in neurotransmitters, playing a role in brain health and cognitive function. Glycine also supports the production of glutathione, a powerful antioxidant that protects cells throughout the body. When you incorporate glycine into your life, you’re not just enhancing your skin—you’re promoting overall well-being.
Glow with Glycine
Glycine may not be the flashiest ingredient in skincare, but its benefits are undeniable. From boosting collagen production to enhancing hydration and calming inflammation, glycine is a powerhouse for maintaining healthy, youthful skin.
Whether you’re using glycine-infused products or incorporating it into your diet, this amino acid deserves a spot in your skincare regimen.
