How to Build a Hydration Powerhouse: The Best Ingredients for Moisturizing Skin

Hydrating and Moisturizing Ingredients List and Dictionary

When it comes to skincare, choosing the right moisturizing ingredients is crucial to maintaining healthy, hydrated skin. However, it’s important to note that there isn’t a single “best” moisturizing ingredient. The most effective moisturizers generally combine ingredients from multiple categories, and your unique skin type will determine which ingredients work best for you. If you’re unsure about your skin type, consider taking a Baumann Skin Type Quiz to identify the right moisturizing ingredients for your skin’s needs.

There are five main categories of moisturizing ingredients that help address different aspects of skin hydration and barrier repair. A comprehensive moisturizer should typically include ingredients from a variety of these categories to provide short-term hydration and long-term barrier protection.

Main Categories of Moisturizing Ingredients

The five main categories of moisturizing ingredients are:

Emollients

Humectants

Occlusives

Oils

Fatty Acids

These categories are essential for creating moisturizers that meet different skin needs, whether you are looking for quick hydration, long-lasting moisture, or barrier repair.

1. Emollients: Softening and Smoothing Agents

Emollients are ingredients that smooth and soften the skin by coating its surface. These ingredients create a temporary, smooth appearance by improving the texture of the skin and allowing light to reflect off it, making the skin look more radiant. Emollients are also known for their ability to mask fine lines and wrinkles.

Common Emollient Ingredients:

Dimethicone: A silicone-based emollient that creates a smooth, silky texture.

Cetearyl Alcohol: A fatty alcohol that smooths the skin and adds moisture.

Cyclopentasiloxane: A lightweight silicone that provides smoothness and softens skin without feeling greasy.

Emollients can sometimes also function as humectants (ingredients that attract moisture) or occlusives (ingredients that create a barrier). In some cases, an emollient will have dual functions to provide both temporary smoothness and longer-lasting hydration.

2. Humectants: Drawing Moisture into the Skin

Humectants are ingredients that pull moisture from the environment or deeper layers of the skin and draw it into the skin’s surface. These ingredients are crucial for giving your skin that fresh, dewy appearance. In humid climates, humectants work especially well by attracting moisture from the air. However, in dry climates, they may pull moisture from the skin, which can lead to dehydration if not paired with occlusives.

Common Humectant Ingredients:

Glycerin: One of the most popular and effective humectants, glycerin attracts moisture from the air and binds it to the skin.

Hyaluronic Acid: Known for its ability to retain moisture, hyaluronic acid holds up to 1000 times its weight in water.

Urea: A natural humectant that is both moisturizing and exfoliating.

Propylene Glycol: A synthetic humectant that helps to attract water into the skin.

When using humectants, it’s best to combine them with occlusives (which create a barrier to lock in moisture) to prevent moisture from evaporating, especially in dry conditions.

3. Occlusives: Locking in Moisture

Occlusives create a protective layer on the skin’s surface, preventing water loss and sealing moisture in. These ingredients are ideal for creating long-lasting hydration. Occlusives are particularly useful in dry, cold climates where moisture can easily escape from the skin. Occlusives are often thicker than other moisturizing ingredients and may leave a greasy or heavy feeling on the skin.

Common Occlusive Ingredients:

Petrolatum (Petroleum Jelly): A powerful occlusive ingredient that locks moisture in and protects the skin from the elements.

Beeswax: A natural occlusive agent that forms a protective barrier on the skin.

Dimethicone: Also functions as an emollient and occlusive, creating a barrier to prevent water loss.

Lanolin: A natural, waxy substance derived from sheep’s wool, providing both occlusive and emollient benefits.

Coconut Oil: While often used as an oil, it also serves as an occlusive ingredient, keeping moisture sealed in.

These ingredients are great for dry or damaged skin, as they help create a barrier to maintain moisture and prevent irritation.

4. Oils: Nourishing and Hydrating Fatty Acids

Oils are natural moisturizers that provide essential fatty acids to help keep the skin hydrated and nourished. Oils are a great source of both unsaturated and saturated fatty acids, which help maintain the skin’s barrier function and improve moisture retention. However, oils are occlusive in nature, so they may not be ideal for acne-prone skin as they could clog pores.

Common Oil Ingredients:

Argan Oil: Rich in essential fatty acids and antioxidants, argan oil is known for its moisturizing and anti-aging properties.

Jojoba Oil: Similar in composition to the skin’s natural sebum, jojoba oil hydrates and balances the skin.

Olive Oil: A deeply hydrating oil packed with fatty acids and antioxidants, ideal for dry or sensitive skin.

Rosehip Oil: Known for its ability to hydrate and improve skin texture, rosehip oil is rich in essential fatty acids and vitamins.

Coconut Oil: A popular oil with strong occlusive properties, helping to seal moisture in.

Although oils are highly beneficial for moisture retention, it’s important to be cautious with oils if you have sensitive or acne-prone skin, as some oils can be comedogenic (clog pores).

5. Fatty Acids: Maintaining Skin’s Barrier Function

Fatty Acids are essential components of the skin’s natural barrier, and they play an important role in maintaining hydration. Fatty acids help prevent moisture loss by forming part of the skin’s lipid barrier, which protects the skin from external aggressors. They also support the production of healthy, functioning skin cells.

Common Fatty Acid Ingredients:

Linoleic Acid: An essential fatty acid that helps to strengthen the skin’s natural barrier.

Oleic Acid: A monounsaturated fatty acid that is highly moisturizing and soothing for dry skin.

Stearic Acid: A saturated fatty acid that helps to protect and condition the skin.

Lauric Acid: Found in coconut oil, lauric acid helps to hydrate and balance the skin’s oil levels.

Fatty acids are typically found in oils and butters and play a significant role in repairing and reinforcing the skin’s barrier, especially in dry or damaged skin.

The Natural Moisturizing Factor (NMF)

The Natural Moisturizing Factor (NMF) is a critical element in maintaining the skin’s hydration. It consists of various natural substances, including amino acids, that are naturally found in the skin and contribute to moisture retention and barrier function.

NMF is primarily composed of amino acids such as histidine, glutamine, and arginine, which have hygroscopic properties—meaning they attract and bind water effectively. These amino acids contribute to the skin’s ability to stay hydrated and retain moisture.

NMF-Related Ingredients:

Pyrrolidone Carboxylic Acid (PCA)

Urea

Lactate

Histidine

Glutamine

Arginine

Although NMF itself is not typically included in skincare products, the amino acids that contribute to its function are commonly found in moisturizers.

DQH Can I use salicylic acid first and then vitamin C? It’s easy to create a skincare routine, but knowing how to use it is another thing entirely. In most cases, if you’re not getting the desired skin results, it could be due to the layering of conflicting ingredients. So, is it possible that salicylic acid and vitamin C are such ingredients? Or are these active ingredients the duo that’s been missing from your skincare routine? If you want answers, stick around because today we are going to explain the benefits of salicylic acid and vitamin C and how they can be used in your daily life. What are the benefits of salicylic acid for skin? Salicylic acid is one of the most commonly used beta hydroxy acids and is favored by many people with oily, acne-prone skin. This acid is derived from willow bark, and unlike its water-soluble relatives (called alpha-hydroxy acids), salicylic acid is oil-soluble, which means it can penetrate deeper into the lower layers of the skin. Once it reaches the lower layers, it can help unclog pores of excess sebum, dirt, bacteria, debris, and impurities. This results in clearer skin tones and greater definition. Not only does salicylic acid benefit the underlying layers, but the outer surface of the skin benefits as well. When applied to the skin, salicylic acid removes the buildup of dead skin cells. This is accomplished by breaking the bonds that hold dead cells to the surface. Over time, this can cause the complexion to look dull and prone to acne, blackheads, and other blemishes. If you’d like to learn more about salicylic acid and how it can improve your skin, check out this dedicated blog post from a beauty insider. What are the benefits of vitamin C for skin? Vitamin C is considered one of the most powerful antioxidants, which means it is very effective at fighting free radicals and preventing them from causing further skin damage. Examples of free radicals include pollution, central heating, UV rays and harsh climate. They attack proteins, fats and cell membranes as soon as they come into contact with the skin, causing signs of premature aging such as fine lines and wrinkles as well as hyperpigmentation, flaky patches of skin and loss of elasticity. Many people usually prefer to use vitamin C in their morning routine as this ingredient gives the complexion a radiant glow. You’ll also find that vitamin C can target areas of hyperpigmentation, plumping the skin and reducing the appearance of fine lines and wrinkles. The thing about vitamin C is that there are a lot of outdated studies going back to the 1950s that describe vitamin C as an unstable skin component. Thanks to improvements in modern technology, this is no longer the case as all products now contain a stable form of vitamin C. Visit The Beauty Insider to learn more about vitamin C. So please check out our blog post. Can I use salicylic acid first and then vitamin C? Yes, you absolutely can. In fact, it’s thought that using salicylic acid before using vitamin C ensures it penetrates faster and works faster. This is an efficient way to utilize two power sources, and the reason has to do with pH. For example, the skin’s natural pH is about 4.7, making it slightly acidic. Salicylic acid and vitamin C are also both acidic, and you’ll find that vitamin C is absorbed quickly into the skin. Therefore, using salicylic acid beforehand can increase the acidity of the skin and allow vitamin C to penetrate into the skin faster. While this is considered an effective way to combine two powerful ingredients, you need to be aware of your skin type and how it reacts to certain active ingredients. Even people with perfect, normal skin can experience skin sensitivity and irritation. Therefore, always consult a doctor or dermatologist before using any new products on your skin. It’s also important to follow skin application rules. In this case, you need to use the product correctly to ensure you get the best results for your skin. If you’re not sure what I mean, the basic rule for skin is to start with the thinnest consistency and work your way up to the thickest consistency. This prevents a barrier from forming on the surface, preventing other active ingredients from penetrating the skin. Can I use salicylic acid at night and vitamin C in the morning? Yes, absolutely, this is considered the most effective way to get returns without any adverse side effects. This is because there is enough time between applications to ensure that the skin’s pH levels return to balance. You’ll also find that Vitamin C is rich in antioxidants and is perfect for use in the morning to ensure your skin is protected and looking its healthiest. Due to the small size of salicylic acid molecules, it is an acid that is able to reach the deepest parts of the skin. While this is effective at keeping skin clear, it also increases the risk of irritation and photosensitivity. Therefore, many people prefer to use powerful BHAs in their evening routine without exposure to UV rays, pollution, or harsh weather. Warning: If you avoid using sunscreen every day, none of these ingredients will do what your skin needs. The combination of chemical peels and powerful ingredients increases the risk of further damage to the skin’s surface. Use SPF 50 every day to keep your skin protected and your lipid barrier healthy, even on cloudy days, keeping your skin in top condition.
