Hyaluronic Acid 101
Hyaluronic Acid: Benefits, Natural Sources & How to Support Hydrated, Healthy-Looking Skin
If your skin often feels dry, tight, dull or less plump than it used to, hyaluronic acid may be one of the most useful ingredients to understand.
Despite its name, hyaluronic acid is not an exfoliating acid. It is a naturally occurring substance found throughout the body, including the skin, eyes and joints. In skincare, it is best known for its ability to attract and hold water, helping the skin look smoother, softer and more hydrated.
What Is Hyaluronic Acid?
Hyaluronic acid, often shortened to HA, is a naturally occurring molecule that helps bind water within the skin. It is an important part of the skin's extracellular matrix and contributes to hydration and a plump, supple appearance.
When skin is well hydrated, it can appear smoother, softer, more radiant and less visibly lined. Hyaluronic acid does not permanently erase wrinkles, but improving hydration can temporarily soften the appearance of fine dehydration lines and help the skin look healthier.
What Happens to Hyaluronic Acid as We Age?
As we age, the amount and distribution of hyaluronic acid within the skin change. At the same time, collagen, elastin and other structural components of the skin also change. Cumulative UV exposure can further contribute to the breakdown of the skin's supportive structures. These changes can contribute to:
- Dryness and dehydration
- More noticeable fine lines
- A less plump appearance
- Changes in firmness and elasticity
- A duller or rougher-looking complexion

Spinach, kale, cabbage and other leafy greens provide nutrients such as magnesium, antioxidants and vitamin C. Vitamin C is especially important because it supports normal collagen formation, which helps maintain the skin's structure.

Turkey, chicken, fish, lean meats, dairy products and legumes provide amino acids. Because collagen is a protein, getting enough dietary protein is important for normal tissue maintenance and repair.

Cocoa contains flavanols and other antioxidant compounds. Choose higher-cocoa dark chocolate and enjoy it in moderation. While cocoa can be part of a nutrient-rich diet, it does not replace daily sunscreen or other protective skincare habits.

Sweet potatoes, carrots, pumpkin and red peppers provide carotenoids and other nutrients. Red peppers are also an excellent source of vitamin C. These foods can support overall nutrition, but they should never be considered a substitute for broad-spectrum sunscreen.
What About Hyaluronic Acid Skincare?
Topical hyaluronic acid is widely used in serums, moisturizers and professional skincare because it acts as a humectant, helping attract water to the skin. It can be especially helpful for skin that feels:
- Dry or dehydrated
- Tight
- Dull
- Rough
- Less plump
For best results, hyaluronic acid is often paired with a moisturizer to help support the skin barrier and reduce moisture loss. Daily broad-spectrum sunscreen is also essential for protecting the skin from UV-related damage.
