What's The Difference Between Hydrating And Moisturizing?
Have you wondered what the difference is between a hydrator and a moisturizer and how to use them right for your skin type? Is it just cosmetic brand marketing terms? Here's how to choose the right skin care product for dry or dehydrated skin.
In fact, both cosmetics terms have the same fundamental role. They help the skin retain moisture to improve or prevent dry, dehydrated, tight, and premature skin. However, which moisturizing products you need and how they work to achieve the end goal vary a lot.
The hydrating ingredients are all about increasing the water content, which will make your skin plumper and more bouncy. Moisturizing products, on the other hand, try to improve the skin's barrier to trap and seal in moisture, prevent water loss, and keep your skin soft and smooth.
How do I know if the product is moisturizing or hydrating the skin?
Since many cosmetic brands use these skin care terms interchangeably, it is not easy to distinguish them just by product names or descriptions. However, you may have an idea by looking at the ingredient lists.
Simply put, moisturizers are oil-based ingredients including squalene, emollients, occlusive agents, and for hydrator, look for humectants that attract water from the top layer of skin or air.
By the time you start paying more attention to it, you may have noticed that there are tons of beauty products out there that do both. Many products contain more than one moisturizing agent.
Some even have all three different active functions (humectants, emollients, occlusive) in one bottle to help hydrate and moisturize your skin at the same time.
Often times, however, your skin can do better with just one hydrator or moisturizer, not both. Read on to find out what your skin really needs.
How do you know If your skin needs a hydrator, moisturizer, or both?
To determine what skin your skin needs, you need to find out if your skin is dehydrated or dry. In general, dehydrated skin is caused by a lack of water, while lipid dry skin is caused by a lack of oil.
How do you know if you have dehydrated skin and how to treat it?
If your complexion looks dull and lackluster and feels too tight and stretched, and fine lines and wrinkles become more visible, your skin may be struggling with dehydration. This means your skin may be lacking hydration, and this is where the hydrator comes in to increase the moisture levels.
You can use both hydrating and moisturizing products together to tackle these two skin problems, but make sure (water-based) hydrator come first, and then (oil-based) moisturizers.
A lightweight hydrating serum and ampoule can penetrate your skin a little deeper due to smaller molecule sizes, while a heavier face cream works on the outer layer of your skin, sealing both water and the benefits of your skin care treatment into the skin.
What are hydrators?
Typically, hydrators contain humectants and their purpose is to increase the water content of the skin's layers, resulting in supple and firm skin. Dehydrated and lackluster skin lacks water; Hence, it needs to be hydrated and hydrating ingredients are generally appropriate for all skin types.
Common humectants include:
- Hyaluronic acid
- Aloe vera
- Snail mucin
- Glycolic acid
- Sodium hyaluronate
- Lactic acid
- Citric acid
- Sodium PCA
- Marine extracts
Humectants are water-soluble and help increase the water content in the skin cells without clogging the pores. We advise you to avoid alcohol as it can actively dry out or irritate the surface of the skin.
How do you know if you have dry skin and how to treat it?
In the meantime, if your skin feels dry, itchy, and prone to flaky skin, and also has a slightly rough texture, your skin's protective barrier may not lock in moisture due to the lack of sebum and epidermal lipids. Apply a moisturizer or facial oil to restore the skin barrier and reduce further water loss.
What are moisturizers?
Moisturizers trap and seal in moisture to build the skin's protective barrier, prevent water loss, and keep the skin soft and smooth. Dry and flaky skin lacks oil and needs to be moisturized.
Moisturizers can be emollient, acting as protective, moisturizing, and lubricating agents, or occlusive, by creating a protective layer on the surface of the skin to prevent moisture loss.
The formulation can be lighter or heavier depending on the season and skin type. In general, you can use a light gel or lotion for the spring, summer months and a heavier cream for dry, cold fall, winter seasons.
If you have oily, acne-prone skin, choose a light, oil-free, non-comedogenic product, usually in the form of a lotion or emulsion.
For dry, sensitive skin, rich creams with emollients and occlusive agents work best for both the face and body, while combination skin can use a lotion or cream, depending on your skin needs.

Common emollients include:
- Cocoa butter
- Shea butter
- Jojoba oil
- Argan oil
- Fatty acids
Common occlusives include:
- Shea butter
- Mango butter
- Mineral oil
- Petroleum jelly (Vaseline)
- Soybean oil
- Castor oil
- Olive oil
Many emollient ingredients that are high in oils tend to have occlusive functions as well. Lanolin oil and dimethicone are the excellent example of an ingredient that ticks both the occlusive and emollient boxes. As a result, you’ll find this ingredient in many face and body care products.
