Understanding Skincare’s Most Popular Ingredient: Hyaluronic Acid
Hyaluronic acid has emerged as a powerhouse in the skincare industry, finding its way into an array of products. But what exactly is hyaluronic acid, and why is it so prevalent?
Hyaluronic Acid Demystified:
Renowned for its ability to «hold 1000 times its weight in water,» hyaluronic acid is a top choice for addressing various skin concerns. From combating dryness to diminishing the appearance of wrinkles, hyaluronic acid plays a pivotal role in maintaining healthy-looking and feeling skin. But let’s delve deeper into what makes this ingredient a skincare staple.
What Is Hyaluronic Acid?
According to Dr. David Shafer, a double board-certified plastic surgeon and founder of the Shafer Clinic Fifth Avenue, hyaluronic acid (HA) is a naturally occurring molecule in our bodies responsible for maintaining skin moisture and hydration levels. This complex sugar, also known as glycosaminoglycans, exhibits wound-healing properties and binds water molecules to retain moisture in our epidermis. However, as we age, our natural HA levels decline, contributing to signs of aging and dry skin. Thankfully, supplementation is possible through various means.
Hyaluronic Acid in Skincare Products:
Hyaluronic acid stands as one of the most—if not the most—prominent skincare ingredients. Similar to its natural counterpart, HA in topical products serves as a humectant, attracting water molecules to hydrate and plump the skin. This makes it an indispensable ally for skin health maintenance and combating signs of aging.
Hyaluronic Acid in Food:
Interestingly, hyaluronic acid can also be sourced from certain foods. Dr. Michelle Henry, a board-certified dermatologist based in New York City, highlights its presence in animal-based foods like milk, fish, and poultry. Dr. Shereene Idriss, another board-certified dermatologist and founder of Idriss Dermatology in New York City, notes that collagen-rich bone broth can support the body’s HA production and promote skin health.
Hyaluronic Acid Fillers:
In cosmetic treatments, hyaluronic acid is commonly found in temporary dermal fillers. Dr. Shafer explains that these injections hydrate and rejuvenate the skin while also addressing wrinkles and fine lines. Approved HA fillers, regulated by the U.S. Food and Drug Administration (FDA), offer various properties tailored to lifting, filling, and smoothing the skin, ensuring safe and effective results.
The Benefits:
Hyaluronic acid delivers unparalleled skin hydration, fortifying the skin barrier and enhancing plumpness and elasticity. Additionally, HA fillers provide hydrating properties while adding volume and firmness to aging skin. Dr. Shafer emphasizes the reversibility of HA fillers, offering an effective safety net in case of dissatisfaction with results.
Potential Side Effects:
While HA is generally well-tolerated, caution is advised with certain formulations. Dr. Henry recommends avoiding products containing low molecular weight HA, as it may cause inflammation and irritation. Alternative ingredients with similar benefits are worth considering, particularly for individuals with a history of allergic reactions to HA.
Incorporating Hyaluronic Acid into Your Skincare Routine:
Given its prevalence, incorporating hyaluronic acid into your skincare regimen is straightforward. Dr. Henry suggests opting for high-concentration serums paired with occlusive components to lock in hydration. However, Dr. Idriss advises limiting HA products to one to two items in your routine to minimize the risk of irritation, considering the abundance of HA-infused products available.
