When it comes to skincare, there are certain ingredients that often steal the spotlight—like hyaluronic acid, vitamin C, or retinol. But one ingredient that tends to fly under the radar, despite its incredible benefits, is glycerin. Often found in moisturizers, serums, and cleansers, glycerin is a powerhouse humectant that plays a crucial role in maintaining healthy, hydrated skin. This unsung hero deserves more recognition, especially given its effectiveness across all skin types.
In this post, we’ll explore the benefits of glycerin in skincare and how it helps to improve hydration, support the skin barrier, and leave your skin feeling soft and smooth.
What is Glycerin?
Glycerin, also known as glycerol, is a natural compound derived from plant oils or animal fats. At ERLY, the glycerin we use in our products is plant-derived. Glycerin is a clear, odorless liquid that has a slightly sweet taste. In skincare, glycerin is prized for its ability to draw moisture from the environment into the skin. As a humectant, glycerin helps attract and retain water, ensuring that the skin stays hydrated and plump.
Unlike many other ingredients that simply add moisture to the surface of the skin, glycerin works by binding water to the skin, providing long-lasting hydration from within. It’s a versatile ingredient that is gentle and non-irritating, making it suitable for even the most sensitive skin types.
The Benefits of Glycerin in Skincare
1. Deep Hydration
One of the primary benefits of glycerin in skincare is its ability to provide deep hydration. It draws moisture into the skin and helps retain it, keeping your skin soft and nourished throughout the day. For those with dry or dehydrated skin, glycerin is a game-changer, as it can help to replenish moisture levels without making the skin feel greasy.
Glycerin is particularly effective when combined with other hydrating ingredients, like hyaluronic acid, which further enhances the skin’s moisture retention. Products like ERLY Daily Splash, which contains three forms of hyaluronic acid alongside glycerin, are an excellent way to ensure your skin stays hydrated all day long.
2. Supports the Skin Barrier
The skin barrier is responsible for protecting the skin from environmental stressors like pollution, UV radiation, and harmful bacteria. When the skin barrier is compromised, it can lead to dryness, irritation, and an increased risk of skin conditions like eczema or rosacea.
Glycerin helps to strengthen and support the skin barrier by ensuring the skin stays well-hydrated. By attracting moisture into the skin and preventing it from evaporating, glycerin helps maintain the skin's natural protective layer, ensuring it stays resilient against external factors. This is particularly important for people with sensitive skin, as a healthy skin barrier can minimize irritation and discomfort.
3. Improves Skin Texture
Regular use of glycerin can improve the overall texture of the skin. Hydrated skin looks smoother, more supple, and plump, while dry skin can appear rough, flaky, or dull. By helping to lock in moisture and reduce water loss, glycerin helps maintain a smooth, soft texture that improves the skin's appearance over time.
For individuals looking for products that enhance skin texture without being too heavy or greasy, ERLY Night Moisturizer is a great option. This moisturizer contains glycerin, along with peptides and hyaluronic acid, to hydrate the skin and support overnight recovery, leaving your skin feeling rejuvenated and soft by morning.
4. Gentle on Sensitive Skin
One of the best features of glycerin is that it is non-irritating and safe for all skin types, including sensitive skin. Unlike some other active ingredients, glycerin does not cause inflammation, redness, or irritation, making it a great choice for those with reactive or delicate skin.
Whether you have rosacea, eczema, or simply sensitive skin, glycerin can help to restore moisture without causing discomfort. It's gentle enough to be used in a variety of skincare formulations, including cleansers, moisturizers, and serums.
5. Non-Comedogenic
Another reason glycerin is so beloved in the skincare community is that it is non-comedogenic, meaning it won’t clog pores. This makes glycerin an excellent ingredient for individuals with oily or acne-prone skin who are looking for hydration without the risk of breakouts.
By helping the skin maintain its moisture balance without adding excess oil, glycerin keeps the skin hydrated and healthy while reducing the likelihood of clogged pores or acne.
How to Incorporate Glycerin into Your Skincare Routine
Glycerin is a versatile ingredient that can be easily incorporated into a skincare routine. Whether you are looking to hydrate your skin, improve its texture, or support the skin barrier, glycerin can be found in a variety of products, from cleansers to moisturizers.
-
Start with a Gentle Cleanser: Begin your skincare routine with a gentle cleanser, like ERLY Face Foam Gentle Cleanser. This will cleanse the skin without stripping it of essential moisture, preparing the skin for the next steps in your routine.
-
Apply a Hydrating Serum: After cleansing, apply a hydrating serum like ERLY Daily Splash, which contains three forms of hyaluronic acid and glycerin. This will help lock in moisture and provide deep hydration to your skin.
-
Moisturize: Finish your routine with a nourishing moisturizer, such as ERLY Night Moisturizer. This will help seal in hydration and support the skin's natural barrier while you sleep. The combination of glycerin, peptides, and hyaluronic acid in this moisturizer ensures your skin stays hydrated and smooth overnight.
Is Glycerin Better Than Hyaluronic Acid?
Glycerin and hyaluronic acid are both humectants, meaning they attract water to the skin. Rather than competing, they actually work very well together.
Glycerin helps attract and retain moisture while supporting the skin barrier. Hyaluronic acid also draws water into the skin and helps improve hydration and plumpness.
Many dermatologist-developed formulas, including ERLY Daily Splash, combine both ingredients because they complement one another instead of replacing one another.
Final Thoughts
Glycerin may not always get the recognition it deserves in the skincare world, but it’s truly an unsung hero of hydration. As a gentle, effective humectant, glycerin draws moisture into the skin, helps maintain a healthy skin barrier, and improves skin texture. Whether you have dry, sensitive, or oily skin, glycerin is a versatile ingredient that can be beneficial for all skin types.
