Hyaluronic acid has become one of the most talked-about skincare ingredients, appearing in serums, moisturisers, and even supplements. It is widely praised for its ability to hydrate, plump, and protect the skin. But what exactly does it do, and why do so many dermatologists and skincare experts recommend it?
This article will explain how hyaluronic acid works, its benefits for skin health, and how to use it effectively.
What Is Hyaluronic Acid?
Hyaluronic acid is a naturally occurring substance found in the skin, joints, and connective tissues. It acts as a humectant, meaning it draws moisture from its surroundings and helps retain water. It can hold up to 1,000 times its weight in water, making it one of the most effective hydrating agents in skincare.
As the body ages, its natural levels of hyaluronic acid decline, leading to drier skin, reduced elasticity, and the formation of fine lines. Environmental factors like pollution, UV exposure, and harsh skincare products can speed up this process. This is why many skincare products include hyaluronic acid to restore moisture and maintain a healthy skin barrier.
The Benefits of Hyaluronic Acid for Skin
1. Intense hydration and moisture retention
Hyaluronic acid attracts and retains water, keeping the skin hydrated throughout the day. Unlike heavy moisturisers that sit on the skin’s surface, it penetrates deeper to improve overall moisture levels. When skin is properly hydrated, it appears plumper, smoother, and healthier.
People with dry or dehydrated skin benefit the most from using hyaluronic acid, as it provides an instant boost in hydration. However, even those with oily skin can benefit, as dehydration often leads to excess oil production.
2. Reduction of fine lines and wrinkles
One of the first visible signs of aging is dehydration, which makes fine lines more pronounced. When the skin lacks moisture, it loses its elasticity and appears dull and tired.
By increasing hydration, hyaluronic acid helps plump the skin, making wrinkles less noticeable. It doesn’t reverse aging, but it can significantly improve the appearance of fine lines and maintain the skin’s youthful look.
3. Strengthening of the skin barrier
The skin barrier plays a vital role in keeping moisture locked in and preventing external damage. A weakened barrier can result in redness, irritation, and increased sensitivity.
Hyaluronic acid helps reinforce the skin barrier by keeping it hydrated and resilient. A strong skin barrier protects against environmental stressors like pollution, UV rays, and harsh weather conditions, reducing premature aging.
4. Improved skin texture and tone
Rough, uneven skin texture is often caused by dehydration or slow cell turnover. Regular use of hyaluronic acid can smooth the skin’s surface, making it feel softer and appear more even.
It also helps improve dull skin by giving it a natural glow. When the skin is properly hydrated, it reflects light better, creating a healthier-looking complexion.
5. Support for wound healing and skin repair
Hyaluronic acid plays a key role in tissue repair. It helps reduce inflammation and promotes faster healing, making it beneficial for acne scars, minor cuts, and post-treatment skin recovery.
Studies have shown that hyaluronic acid can accelerate wound healing by encouraging the growth of new skin cells. This makes it useful for those with acne-prone skin or people recovering from laser treatments and chemical peels.
6. Suitable for all skin types
Unlike some skincare ingredients that can cause irritation, hyaluronic acid is well tolerated by most skin types, including sensitive and acne-prone skin. It hydrates without clogging pores, making it a good option for oily and combination skin.
People with eczema or rosacea can also benefit from hyaluronic acid, as it helps to soothe and calm irritated skin while keeping it hydrated.
How to Use Hyaluronic Acid in Your Skincare Routine
To get the most out of hyaluronic acid, it is important to apply it correctly.
-
Apply to damp skin. Hyaluronic acid works best when applied to damp skin, as it needs moisture to bind to. If applied to dry skin, it may pull water from deeper layers, causing dryness.
-
Layer under a moisturiser. Hyaluronic acid attracts water but does not seal it in. A moisturiser helps lock in hydration and prevent evaporation.
-
Use it morning and night. In the morning, it hydrates and preps the skin for the day ahead. At night, it supports the skin’s natural repair process.
-
Pair with other beneficial ingredients. Hyaluronic acid works well with vitamin C, niacinamide, peptides, and retinol. Avoid using it with strong exfoliating acids like glycolic acid in the same step, as this may reduce its effectiveness.
Are There Any Downsides?
Hyaluronic acid is generally safe for all skin types, but there are a few things to keep in mind.
-
It does not replace a moisturiser. Hyaluronic acid attracts water but does not lock it in, so it should always be followed with a moisturiser.
-
Higher concentrations are not necessarily better. A well-formulated product with 1 to 2 percent hyaluronic acid is effective.
-
It may not work as well in very dry climates. If there is little humidity in the air, hyaluronic acid may pull moisture from deeper layers of the skin. In this case, using a heavier moisturiser can help prevent dryness.
Hyaluronic Acid Supplements
Beyond topical skincare, hyaluronic acid is also found in oral supplements, often marketed for skin hydration and joint health. Research suggests that taking hyaluronic acid orally may help improve skin moisture, increase elasticity, and support joint lubrication.
While topical hyaluronic acid provides immediate hydration, oral supplementation can help replenish the body’s natural stores over time. This makes it a good option for those looking to improve skin health from within.
Applying hyaluronic acid to the skin works well, but for long-term hydration and skin health, supplementing with hyaluronic acid can be even more effective. Simply Nootropics Vital Beauty provides 100 mg of hyaluronic acid per serve, helping to maintain hydration, elasticity, and overall skin resilience.
Unlike topical products that only provide surface hydration, Vital Beauty works from within, replenishing moisture at a deeper level. It supports collagen production, helps prevent moisture loss, and improves skin firmness over time.
