Understanding Hyaluronic Acid
Introduction to HA
Hyaluronic acid (HA) is a naturally occurring substance in the body that plays a critical role in skin hydration and elasticity. This powerful compound can hold up to 1,000 times its weight in water, making it an exceptional humectant that helps maintain skin moisture and prevents transepidermal water loss (TEWL) (Healthline). As individuals age, levels of hyaluronic acid in the skin decline, contributing to common aging concerns such as fine lines, wrinkles, and reduced skin elasticity (The Ordinary).
Benefits for Skin
The benefits of hyaluronic acid extend far beyond simple hydration. The following table summarizes some of the key advantages of incorporating HA into skincare routines:
| Benefit | Description |
|---|---|
| Intense Hydration | Draws moisture from the environment and binds it to skin for lasting hydration. |
| Improved Skin Elasticity | Helps maintain skin’s structure by retaining moisture, resulting in a plumper appearance. |
| Soothing Properties | Gentle and suitable for all skin types, making it ideal for sensitive skin. |
| Reduces Fine Lines and Wrinkles | May help minimize the appearance of fine lines as it supports skin hydration and elasticity. |
| Enhances Overall Skin Texture | Contributes to a smoother, more youthful-looking complexion by keeping skin well-moisturized. |
Hyaluronic acid is recognized for its compatibility with various skincare ingredients, including retinol and alpha hydroxy acids (AHAs). However, proper application is crucial, as applying HA on dry skin can lead to dehydration by drawing moisture away from the skin.

Opting for products with a suitable molecular weight can ensure better hydration without adverse reactions.
Safe Application Guidelines
To achieve optimal results with hyaluronic acid, the concentration should be kept below 2 percent. Products with very low molecular weight (approximately 5 kDa) can penetrate deeply, potentially carrying unwanted substances and bacteria into the skin. However, it is worth noting that hyaluronic acid commonly does not cause allergic reactions, as it is naturally produced by the body.
When applying HA, it is essential to use it as part of a well-structured skincare routine. For proper application, consider the following guidelines:
- Apply on damp skin to enhance absorption.
- Follow up with a moisturizer to lock in hydration.
- Use as an individual serum or in combination with other products.
Combination with Other Ingredients
Hyaluronic acid works well with various ingredients, enhancing its hydrating properties. For effective skincare layering, it is advised to apply products from most active to least active, and from thinnest to thickest. This means HA-based serums should be the last in the serum phase of the regimen. Following it up with emollients and occlusives helps seal in moisture (Go-To Skincare).
However, it is important to know which ingredients complement hyaluronic acid. Products like vitamin C can enhance its effects, while certain combinations (e.g., with retinol) may lead to irritation.
