Hyaluronic acid is a natural substance found in the body that plays an important role in keeping skin moisturized and wrinkle-free. It works by retaining water molecules in the skin, plumping it from within. As we age, our natural levels of hyaluronic acid decline which leads to dry, wrinkled skin. However, newer skincare products containing hyaluronic acid are helping people maintain youthful, healthy looking skin.
What is Hyaluronic Acid?
Hyaluronic acid (HA) is a glycosaminoglycan found in almost every tissue of the body, especially the skin. It has a unique ability to hold 1000 times its weight in water, forming a moisture-binding gel that cushions and lubricates joints and tissues. In the skin, it works to retain moisture, keeping it soft, supple and firm. Younger skin naturally produces optimal levels of HA which is why babies have such soft, blemish-free skin. As we age, HA levels deplete leaving skin dry and wrinkled. Dermal HA levels begin declining as early as age 20 and production halves by age 50.
Benefits of Topical Hyaluronic Acid
Now that we understand HA's moisture-binding properties, it's clear why applying it topically can benefit skin in multiple ways:
- Moisturization - HA plumps the upper dermal layer, holding skin-nourishing water close to the surface. This visibly hydrates and softens skin.
- Wrinkle reduction - Well-hydrated skin appears plumper, minimizes the appearance of fine lines and wrinkles. Over time it may help diminish their appearance.
- Increased collagen - HA stimulates fibroblasts to produce collagen and elastin for firmer, more elastic skin.
- Faster wound healing - HA's hydrating benefits accelerate healing of small wounds, burns and after procedures.
- Less visible pores - Hydrated skin has a smoother, brighter appearance that disguises the look of pores.
- Skin protection - HA forms a moisture barrier to shield skin from environmental damage.
- Youthful glow - Properly hydrated skin looks and feels more radiant and healthy.
Choosing the Right Hyaluronic Acid Product
WithHA's skin benefits validated by research, it's unsurprising the ingredient is in countless skincare products. But not all hyaluronic acid is created equal. Choosing the right formula comes down to three key factors:
Molecular Weight
HA's effectiveness depends on its molecular weight (size). Low and medium weight versions hydrate skin superficially while high weight penetrating HA replenishes deeper levels. Look for products with both sizes for optimal results.
Alternative Delivery Systems
For HA to work optimally, it must reach the dermal layers. New time-release and micro-encapsulation technologies boost absorption. Brands like Dermelect use micro-droplets for deep yet gradual hydration.
Additional Ingredients
Pairing HA with antioxidants, peptides and ceramides magnifies its impact. Glycerin improves its water-binding. Hyaluronic serums containing aloe, green tea or vitamin C hydrate and protect skin all day.
Popular Hyaluronic Acid Product Categories
Face Serums
Lightweight, fast-absorbing serums deliver hydration directly to the skin. Best applied to damp, cleaned skin in the a.m. and p.m. Look for formulas with other active ingredients and multiple HA weights.
Moisturizers
Creamier moisturizers deeply nourish skin with occlusive ingredients. Opt for ones containing ceramides, fatty acids and antioxidants along with HA. Great for very dry skin types.
Eye Creams
Thin, ointment-like textures hydrate delicate under-eye skin without feeling heavy. Ingredients like caffeine also reduce puffiness. Use SPF versions for daytime.
Sheet Masks
Single-use hydrating sheet masks instantly plump and refresh skin. Ingredients like aloe soothe, while hyaluronic formulas hydrate. Great pre-treatments or weekly indulgence.
Hand Creams
Formulas containing shea butter, glycerin or antioxidants hydrate hands, fighting signs of aging. Look for pumps/dispensers ideal for on-the-go moisturizing.
Tips for Effectively Using Hyaluronic Acid Products
To fully experience HA's skin benefits, follow these application tips:
- Prep skin by cleansing it to remove dirt/oil before applying.
- Spray or pat a few drops of water onto skin first as HA works best on damp skin.
- Apply serum, moisturizer or cream in upward, outward motions massaging it in.
- Follow with an SPF product during the day to shield hyaluronic acid-plumped skin.
- Reapply moisture during the day as needed, especially in dry climates.
- Use a humidifier at night to keep skin from dehydrating as you sleep.
- Exfoliate weekly to allow HA to fully penetrate skin’s surface layers.
As the skincare benefits of Hyaluronic acid are realized, expect to see even more innovative product delivery systems emerging. With consistent use, HA serums and moisturizers provide a natural route to younger, healthier looking complexions.
