What is Glycerin?

Glycerin, also known as glycerol, is a natural compound derived from vegetable oils or animal fats. It appears as a clear, colorless, odorless, and syrupy liquid with a sweet taste. In the realm of skincare, glycerin is primarily recognized for its humectant properties. This means it has the ability to draw moisture from the environment and deeper layers of the skin into the outer layer, enhancing hydration.

How is Glycerin Made?

Glycerin can be produced through two primary processes:

  1. Saponification: This process involves the chemical reaction between fats or oils and an alkali, resulting in soap and glycerin.
  2. Transesterification: In this method, vegetable oils are treated with an alcohol, producing glycerin and fatty acids.

Both methods yield glycerin that is suitable for use in cosmetics and skincare products.

Is Glycerin Water or Oil Based?

This is the crux of our inquiry. Glycerin is technically classified as a water-soluble compound, which means that it dissolves in water rather than in oil. This property makes it an excellent humectant, as it can attract and bind water molecules, effectively increasing hydration levels in the skin.

Comparing Water and Oil-Based Ingredients

To further clarify, let’s explore the differences between water-based and oil-based ingredients:

  • Water-based Ingredients: These are typically light, easily absorbed by the skin, and are excellent at hydrating. They tend to evaporate quickly but can draw moisture from the air or deeper skin layers.
  • Oil-based Ingredients: These are thicker, provide a barrier to prevent water loss, and are often occlusive in nature. They can be beneficial for sealing in moisture but may not provide hydration on their own.

Glycerin’s Unique Role

Glycerin’s water-soluble nature allows it to work synergistically with oil-based ingredients in formulations. When included in a moisturizer or serum, glycerin draws moisture into the skin, while oils help to lock that moisture in, creating a balanced and effective skincare product.

The Benefits of Glycerin in Skincare

The inclusion of glycerin in skincare products offers a variety of benefits, making it a beloved ingredient among dermatologists and skincare enthusiasts alike:

  1. Intense Hydration: Glycerin is one of the most effective humectants available, significantly enhancing skin hydration. A study published in 2016 confirms glycerin's efficacy compared to other humectants, making it a vital ingredient for anyone seeking to improve skin moisture.
  2. Improves Skin Barrier Function: Glycerin helps to strengthen the skin's natural barrier, protecting it against environmental irritants and pollutants.
  3. Accelerates Wound Healing: Research suggests that glycerin can expedite the healing process of minor wounds and abrasions, making it beneficial for those with sensitive or compromised skin.
  4. Soothes and Softens: Glycerin provides a soothing effect, which can alleviate irritation and dryness, making it particularly useful for those with sensitive skin types.
  5. Non-comedogenic: Glycerin is safe for acne-prone skin, as it does not clog pores and can help maintain hydration without leading to breakouts.

Glycerin in Moon and Skin Products

At Moon and Skin, we believe in the power of clean and thoughtful formulations. Our Hyaluronic Brightening Moisturizer incorporates glycerin alongside hyaluronic acid to ensure deep hydration while brightening the skin. This product exemplifies how glycerin can work in harmony with other ingredients to produce optimal results for your skin.

How to Use Glycerin Effectively

Using glycerin in your skincare routine can yield amazing results, but it’s essential to use it correctly to avoid potential pitfalls. Here are some tips for effectively incorporating glycerin into your routine:

  1. Dilution: If using glycerin in its pure form, always dilute it with water or another hydrating agent like rosewater. This helps to prevent potential dehydration caused by glycerin drawing moisture from deeper skin layers.
  2. Layering: Apply glycerin-based products after cleansing and toning but before heavier creams or oils to maximize absorption.
  3. Combination with Occlusives: Pair glycerin with oil-based products to seal in moisture and enhance hydration. For example, follow up your serum application with a nourishing oil or moisturizer.
  4. Use in Humid Conditions: Glycerin works best in humid climates, where it can draw moisture from the air. In dry environments, ensure you are using it in combination with occlusives to avoid potential dehydration.

A Step-by-Step Guide to Using Glycerin on Your Face

  • Step 1: Cleanse your face with a gentle cleanser. We recommend our Superfood Cleanser formulated to nourish and hydrate the skin while removing impurities.
  • Step 2: Apply a diluted glycerin solution using a cotton pad or your fingertips, gently patting it into the skin.
  • Step 3: Allow the glycerin to absorb for a few minutes.
  • Step 4: Follow up with a hydrating serum or moisturizer, such as our Hyaluronic Brightening Moisturizer to lock in the moisture.

Potential Drawbacks and Side Effects

While glycerin is generally safe and beneficial for the skin, there are a few considerations to keep in mind:

  1. Dehydration Risks: As a strong humectant, glycerin can dehydrate skin if not used correctly, especially in low-humidity environments. Always pair it with occlusive agents or ensure proper dilution.
  2. Allergic Reactions: Although rare, some individuals may experience allergic reactions to glycerin. If you notice redness, itching, or irritation, discontinue use immediately.
  3. Undiluted Use: Applying glycerin in its pure form can lead to skin irritation or blistering. We recommend choosing products formulated with glycerin instead.
  4. Skin Type Considerations: Individuals with extremely oily skin may want to use glycerin with caution, as it can create a feeling of stickiness when used in excess.

Choosing the Right Glycerin Products for Your Skin Type

When selecting glycerin-based products, it’s essential to consider your unique skin type and needs:

  • Dry Skin: Look for moisturizers that combine glycerin with occlusive agents, like our Hyaluronic Brightening Moisturizer, to provide lasting hydration.
  • Sensitive Skin: Opt for products with gentle formulations that include glycerin, avoiding harsh additives or fragrances. Our Stem Cell C Serum is a great option that’s also acne-safe.
  • Oily or Acne-Prone Skin: Select lightweight, non-comedogenic products that incorporate glycerin without heavy oils. Our Liposomal Retinol Serum is designed to deliver results while maintaining a lightweight feel.
