Navigating the world of skin care can be bewildering, especially when it comes to terms such as moisturizing, hydrating, and nourishing. To ensure proper skin health, all three are necessary, which is why learning the differences between them and their functions is non-negotiable.
When applied to the skin, moisturizers work to maintain hydration by preventing water from escaping. These products contain different ingredients that play various roles, such as stopping water loss and helping your skin shed old cells. (1)
On the other hand, keeping your skin hydrated goes beyond just how it looks and feels. A lack of skin hydration affects not only its appearance but also the molecular processes, enzymes, and signals within. (2)
Lastly, skin nourishment is like giving your skin a healthy, hearty meal. It involves providing essential nutrients to keep your skin vibrant and protected. This means using products with antioxidants and other protective compounds that are naturally found in your skin. (3)
This article will break down all three – moisturizing, hydrating, and nourishing – in plain language.
What Is the Difference Between Skin Hydration, Nourishment, and Moisturization?
Here is what skin hydration, nourishment, and moisturization mean and how they differ from one another.
| Aspect | Skin Moisturizing | Skin Hydrating | Skin Nourishing |
|---|---|---|---|
| Objective | Retain surface moisture | Increase skin water content | Provide essential nutrients |
| Focus | Prevent water loss | Deep hydration in cells | Nourishment from vitamins and minerals |
| Key Players | Emollients, humectants | Hyaluronic acid, glycerin | Nutrient-rich ingredients |
| Results | Soft, smooth skin | Plump, elastic skin | Healthy, radiant skin |
| Examples | Lotions, creams | Hyaluronic acid, glycerin | Serums |
Skin Moisturization
Moisturizers are like superheroes for your skin as they keep it healthy and happy. They work in three ways: humectants bring water to your skin, emollients smooth and soften it, and occlusives lock in moisture.
Imagine them as a protective shield, covering small cracks, soothing your skin, and guarding against friction. (4)
In short, moisturizers help your skin absorb, hold, and spread water while preventing water loss, keeping the skin feeling smooth.
What are some good moisturizing agents and how do they work?
How moisturizers work depends upon the type of moisturizer you’re using. There are four main kinds.
Emollients
Emollients are skin-nourishing ingredients that bring softness, flexibility, and smoothness to your skin, such as lipids and oils. They act as protectors, forming a shield against harmful environmental elements.
Another example of emollients is ceramides, which are natural defenders and team up with other lipids to create this barrier. (5)
Squalane
Squalene, a natural skin lipid, plays a key role in skin health. Your skin produces it, but after 30, its production slows, leading to dry skin. It’s found in both plant and animal sources.
Squalane, a stable form of squalene, is an effective moisturizer, protecting the skin from UV damage. It’s non-oily and odorless and is great for sensitive skin.
Besides moisturizing, it helps with skin conditions such as acne and dermatitis. (4)(5)
Humectants
Humectants are like moisture magnets for your skin, drawing water from both the deeper skin layers and the environment. They include lactic acid and amino acids, which form the natural moisturizing factor.
Glycerol is the most potent humectant and keeps your skin hydrated. (5)
Occlusives
Occlusives are like protective shields for your skin – they block water loss. They form a barrier, with mineral oils such as liquid paraffin and petrolatum leading the pack.
While petrolatum is a top-notch moisturizer, some may find it a bit greasy. Lanolin from sheep is another option. (4)(5)
What are the benefits of using a moisturizer?
Moisturizers work in several ways to keep your skin healthy. They hydrate, making your skin soft and flexible.
Some moisturizers also have anti-inflammatory properties that soothe irritated skin. In addition, they can reduce itching, thus providing relief.
Certain moisturizers even offer sun protection. (5)(6)
Skin Hydration
Water is essential for normal skin functions. Skin hydration is about water within cells and is improved by increasing water intake or using hydrating products. This enhances the skin’s ability to absorb moisture.
Overall body hydration considers the body’s water content, tracked through fluid intake and changes in body mass and involves dehydration and rehydration processes.
Meanwhile, maintaining skin moisture involves preserving the skin’s natural oils through the lipid cells, creating a protective barrier against dryness.
This is why hydration is very important as it involves bringing water into the layers of the skin and not just on the surface. (7)
What are some good hydrating agents and how do they work?
Here are some of the best hydrators on the market.
Hyaluronic acid
The skin’s moisture hero is hyaluronic acid (HA), a special molecule that grabs and holds onto water. It’s like the skin’s water reservoir. Most of our body’s hyaluronic acid is in the skin, making up half of it.
The dermis, a layer beneath the outer skin, has a lot of hyaluronic acid, especially in the papillary dermis. This hyaluronic acid helps balance water, pressure, and ions in the skin. Think of it like a regulator that keeps everything stable.
So, to keep your skin hydrated, hyaluronic acid products should be #1 on your list. (8)
Glycerin
Using cosmetic ingredients that restore hydration and reduce water loss such as glycerin enhances your skin’s look and feel. Glycerin is a powerful hydrator that helps maintain skin hydration.
In one study, topical glycerin proved effective in a mouse model with hydration issues. (9)
Ceramides
Ceramides are a part of the skin’s lipid team, along with fatty acids and cholesterol. This team creates a structure that keeps your skin hydrated and protected.
Imagine it as a shield made of tiny, straight chains that become solid at skin temperature, making it strong and less permeable.
When skin disorders mess with this team, especially ceramides, problems can ensue. Using formulations with ceramides can help restore the skin’s hydration balance. (10)
What are the benefits of using a hydrator?
A hydrator helps to keep your skin well moisturized, preventing dryness and flakiness.
Hydrators also improve the skin’s elasticity, making it look plump and youthful.
Skin Nourishment
Skin nourishment is the practice of providing essential nutrients to the skin to maintain its health, appearance, and functionality. Just as your body needs proper nutrition, your skin requires care to stay supple and radiant.
What are some good nourishing agents and how do they work?
Here are some best hydrators on the market.
Vitamin C
Vitamin C, a powerful antioxidant, fights off photoaging and protects the skin from sun damage. It’s like a bodyguard for your skin, preventing collagen breakdown and promoting synthesis, keeping your skin firm.
Plus, it helps in reducing pigmentation, giving you a bright and even skin tone. (11)
Retinoids
Retinoids are vitamin A derivatives. They help in combating fine lines, wrinkles, and hyperpigmentation. They also stimulate collagen production for firmer, smoother skin.
Additionally, retinoids speed up cell turnover, shedding old, damaged cells and revealing fresh, youthful skin. Plus, they help bid farewell to acne by preventing clogged pores and calming inflammation. (12)
Peptides
Peptides fight free radicals, reducing aging signs and inflammation.
Fish collagen peptides, such as ACH and CCH, boost collagen, preventing sagging. Peptides from fish scales also protect against UVB damage, maintaining skin thickness and hydration.
Moreover, elastin peptides inhibit UV-induced issues, keeping your skin moisturized. (13)
