By the end of this post, we hope to empower you with the knowledge to make informed skincare choices that align with our mission of providing clean, thoughtful skincare for every phase of life.

What is Pure Glycerin?

Pure glycerin is a colorless, odorless, and viscous liquid that is classified as a sugar alcohol or polyol. It can be derived from both plant and animal sources, though most commercially available glycerin today is plant-based, extracted from vegetable oils through a process known as hydrolysis. Glycerin has been a part of human history since the late 18th century when Swedish chemist K.W. Scheele first isolated it while studying olive oil.

The Composition of Glycerin

Chemically, glycerin is a type of carbohydrate that consists of three hydroxyl (–OH) groups. This unique structure makes glycerin an excellent humectant—an ingredient that attracts and retains moisture. Glycerin’s ability to draw water from the environment and deeper skin layers to the outer skin barrier is what makes it so valuable in skincare formulations.

The Purity Factor

In the cosmetics industry, glycerin is considered pure when it contains at least 95% glycerin, with the remaining percentage usually consisting of water and other organic compounds. The U.S. Food and Drug Administration (FDA) recognizes glycerin as safe for human use, which is why it’s frequently found in a variety of products, from foods to pharmaceuticals and, importantly, skincare.

Why is Glycerin Beneficial for the Skin?

Glycerin’s multifaceted benefits make it a highly sought-after ingredient in skincare. Here are several reasons why glycerin is considered a powerhouse for skin health:

1. Hydration Hero

Glycerin’s primary function is as a humectant. It draws moisture from the air and deeper layers of the skin, effectively hydrating the outer layer. A 2017 study highlighted glycerin's effectiveness in retaining moisture, particularly in the stratum corneum, the outermost layer of the skin. By maintaining hydration levels, glycerin can help keep your skin plump, smooth, and youthful.

2. Skin Barrier Function

The skin barrier is crucial for protecting against environmental irritants and preventing moisture loss. Glycerin enhances the skin's barrier function, allowing it to lock in moisture and shield against harmful elements, such as pollution and UV rays. This is especially important for individuals with sensitive skin.

3. Wound Healing Properties

Research suggests that glycerin not only retains moisture but also promotes skin healing. It can accelerate the healing process for minor wounds and irritations by providing a protective layer that allows the skin to recover more efficiently. Glycerin's affinity for water helps to soothe and restore damaged skin.

4. Soothes Skin Irritation

Glycerin can help alleviate irritation and redness caused by various skin conditions. Its gentle, non-irritating nature makes it suitable for all skin types, including sensitive and acne-prone skin. By counteracting irritants and restoring hydration, glycerin can improve overall skin texture.

5. Non-Comedogenic

For those worried about clogged pores, glycerin is non-comedogenic, meaning it won’t block your pores. This makes it an excellent choice for oily and acne-prone skin types, providing hydration without contributing to breakouts.

How to Incorporate Glycerin into Your Skincare Routine

Incorporating glycerin into your skincare routine can be straightforward and beneficial. Here are some practical tips on how to use glycerin effectively:

1. Choose Glycerin-Rich Products

The easiest way to enjoy the benefits of glycerin is to choose products that include it as a key ingredient. At Moon and Skin, we prioritize glycerin in our formulations to provide hydration and support your skin’s health. Our Hyaluronic Brightening Moisturizer is an excellent choice, as it combines glycerin with other hydrating agents to nourish and brighten your skin.

2. Dilute for Direct Application

If you're considering using pure glycerin, it's essential to dilute it before applying it directly to your skin. Mix glycerin with a carrier such as rosewater or aloe vera gel to create a soothing and hydrating treatment. This combination helps to minimize any potential irritation while maximizing hydration.

3. Use in Layering Techniques

For those who enjoy a multi-step skincare routine, consider layering glycerin-containing products. Start with a hydrating serum like our Stem Cell C Serum, followed by a glycerin-infused moisturizer. This layering technique helps lock in moisture and provides a more effective hydration boost.

4. Add to DIY Formulations

If you enjoy creating custom skincare products at home, glycerin is a fantastic addition. You can mix it into homemade face masks, scrubs, or toners. Just remember to dilute it properly to avoid any skin irritation.

5. Incorporate into Body Care

Glycerin isn’t just for the face; it’s also beneficial for the body. Look for body lotions or creams that feature glycerin to help hydrate dry areas, especially during the colder months when skin tends to lose moisture.

Glycerin vs. Other Humectants

While glycerin is a superstar in the realm of humectants, it's worth noting how it compares to other popular ingredients:

1. Hyaluronic Acid

Hyaluronic acid is another well-known humectant that can hold up to 1,000 times its weight in water. While both glycerin and hyaluronic acid are effective in drawing moisture, glycerin is often more affordable and less prone to degradation in formulations. Combining both can create a powerful hydrating effect.

2. Urea

Urea is a mild exfoliant that also acts as a humectant. It helps to enhance the skin's moisture content while promoting cell turnover. Glycerin is often used alongside urea in skincare products to maximize hydration and improve skin texture.

3. Aloe Vera

Aloe vera is a popular natural ingredient known for its soothing and hydrating properties. While aloe vera provides cooling benefits and additional vitamins, glycerin excels in moisture retention, making them a powerful combination in many skincare formulations.

Possible Side Effects of Glycerin

Despite its many benefits, glycerin can cause side effects for some individuals. It's essential to be aware of these potential issues:

1. Skin Irritation

While glycerin is usually safe, some people may experience irritation, especially if using pure glycerin without dilution. It’s crucial to test any new product on a small area of skin before applying it more broadly.

2. Dehydration in Low Humidity

In extremely low humidity conditions, glycerin may draw moisture away from the skin rather than into it, potentially leading to dehydration. This is why it’s often recommended to use glycerin in conjunction with occlusive agents that can lock in moisture.

3. Allergic Reactions

Though rare, some individuals may have allergic reactions to glycerin. Signs of an allergic reaction can include redness, itching, or a rash. If you experience these symptoms, discontinue use and consult a healthcare professional.

Conclusion

In summary, pure glycerin is an incredibly versatile and beneficial ingredient for skincare. Its ability to hydrate, protect, and heal makes it a staple in many effective formulations. At Moon and Skin, we harness the power of glycerin in our products to provide clean, effective skincare solutions for every phase of life.
