What is Hyaluronic Acid?
Hyaluronic acid (HA) is a naturally occurring compound that is found throughout the body. It is a clear, gooey substance that is produced by cells called fibroblasts. HA is present in large amounts in the skin, inside joints, within eye sockets, and other tissues where it helps retain collagen, increase moisture, and provide cushioning.
HA is unique because it can hold up to 1000 times its weight in water. This helps attract and retain moisture to keep skin plumped and hydrated. HA declines with age, which contributes to wrinkles, fine lines, dullness, and dryness. Using skincare products with HA can help replenish this moisture-binding ingredient.
Benefits of Hyaluronic Acid
Here are some of the top benefits of hyaluronic acid:
- Boosts skin hydration and locks in moisture
- Plumps up skin to minimize signs of aging
- Soothes dry, irritated skin
- Protects against environmental damage
- Supports healthy collagen levels
- Reduces appearance of fine lines and wrinkles
- Speeds up wound healing
- Relieves joint pain and lubricates eyes
Hyaluronic Acid in the Body
HA is present throughout the body in various tissues. Some of its roles include:
- Joints - Acts as a lubricant and shock absorber
- Eyes - Helps retain moisture in the eyes
- Skin - Binds up to 1000 times its weight in moisture to keep skin hydrated and plump
- Cartilage and tendons - Provides resilience and flexibility
HA levels start to decline around ages 20-30. This reduction over time is a major contributor to joint pain, dry eyes, skin aging, and reduced moisture.
Benefits of Hyaluronic Acid for Skin
Hyaluronic acid has become a star anti-aging ingredient because of its incredible ability to hydrate skin and improve signs of aging. Here are some of the top benefits of hyaluronic acid for skin:
Plumps and Hydrates Skin
The single biggest benefit of HA for skin is its unparalleled moisturizing properties. HA can grab onto and retain huge amounts of moisture, over 1000 times its molecular weight. This helps skin stay hydrated, plump and dewy.
Fills In Fine Lines and Wrinkles
By boosting moisture levels in the skin, HA fills in fine lines and wrinkles from the inside-out. The added hydration helps smooth the skin’s surface for a more youthful, glowing appearance.
Supports Collagen and Elastin
Collagen and elastin give skin its firmness and elasticity. HA helps stabilize and nourish these proteins to keep skin toned, tight and resilient.
Protects from Free Radicals
Environmental factors like sun, pollution and smoke contain free radicals that break down collagen and accelerate skin aging. HA forms a protective film on the skin that acts as a free radical scavenger to reduce damage.
Soothes Irritation and Inflammation
HA has anti-inflammatory properties that help calm irritated or sensitive skin. By restoring moisture balance, it allows skin to heal faster after breakouts, procedures, or injuries.
Non-Comedogenic and Well-Tolerated
Hyaluronic acid has a non-comedogenic structure which means it won’t clog pores. It is generally well-tolerated even by those with sensitive skin.
Hyaluronic Acid Serums
Serums deliver powerful skin solutions in a lightweight, fast-absorbing formula. Hyaluronic acid serums contain ultra-concentrated HA to provide intense hydration and anti-aging benefits.
Benefits of Hyaluronic Acid Serums
Hyaluronic acid serums offer these advantages:
- Lightweight, fast-absorbing texture
- Higher HA concentration than moisturizers
- Quickly replenish hydration
- Improve the look of wrinkles
- Brighten dull, dry skin
- Layer well under moisturizer, makeup
- Suitable for all skin types
When to Use a Hyaluronic Acid Serum
HA serums can be used by any skin type. They are beneficial for:
- Dry, dehydrated skin
- Oily and acne-prone skin
- Normal, combo skin
- Sensitive skin that is irritated or inflamed
- Mature skin showing signs of aging
- Dull, tired skin in need of a glow
- Skin exposed to harsh weather or environment
You can use an HA serum morning and night after cleansing and before heavier creams. Apply 3-5 drops and gently pat it into skin until fully absorbed.
What to Look for in Hyaluronic Acid Serums
With so many HA serums on the market, it helps to know the most important factors:
- Multiple Molecular Weights - A mix of low, medium and high molecular weight HA can penetrate varying skin layers for a more comprehensive effect.
- Pure Formulation - Look for formulas without a lot of added fillers, dyes or irritants.
- High HA Concentration - 1-2% is an effective concentration for most serums.
- Quality Ingredients - The best serums contain other proven anti-aging ingredients like vitamin C, antioxidants and peptides.
- Lightweight Texture - Hydrating without feeling sticky or heavy.
Other Ways to Use Hyaluronic Acid
Besides serums, here are some other products that leverage the benefits of hyaluronic acid:
Moisturizers
Many lotions, creams and moisturizers now contain HA. The hydration supports the moisturizing base and helps prevent transepidermal water loss.
Hydrating Toners
Hyaluronic acid toners help prep and hydrate skin after cleansing. The toner deeply penetrates skin to optimize absorption of additional skin care products.
Sheet Masks
Sheet masks allow deeper penetration of HA for boosted hydration. This quick fix can provide a surge of moisture and anti-aging effects.
Eye Creams
The skin around the eyes is delicate and prone to showing signs of fatigue and age. HA eye creams refresh this area by intensely moisturizing and plumping up fine lines and wrinkles.
Lip Treatments
Lips lose moisture easily, leading to dryness and fine lines. HA lip treatments add both short and long-term hydration to smooth and volumize lips.
Injections
Dermal fillers like Juvederm contain cross-linked hyaluronic acid. Injected directly into wrinkles, folds and lips, the fillers provide immediate plumping and smoothing.
Side Effects of Hyaluronic Acid
Hyaluronic acid serums and skincare are very safe for most people. There are few risks or side effects. However, some things to keep in mind:
- Hyaluronic acid supplements may interact with certain medications like blood thinners. Discuss with your doctor before taking an oral supplement.
- Topical HA creams and serums can cause mild redness or irritation in those with very sensitive skin. Do a patch test first.
- If you have an upcoming surgery, stop using topical HA 1-2 weeks beforehand since it can interfere with anesthesia.
- Some people may experience temporary swelling after HA injections as the skin adjusts. This typically resolves within a few days.
Before and After Hyaluronic Acid
Hyaluronic acid can produce noticeable anti-aging effects, especially with consistent use over time. Here is what you might see:
1 Week

FAQs
Can I use vitamin C serum with hyaluronic acid?
Yes, vitamin C and hyaluronic acid work very well together. The vitamin C provides antioxidant protection while the HA draws in moisture. Use vitamin C in the morning followed by HA serum.
Does hyaluronic acid expire?
Hyaluronic acid products can expire within 1-2 years. Look for an expiration date on the packaging. If the product ever looks or smells off, it’s best to replace it.
Can I use retinol and hyaluronic acid together?
You can safely use both retinol and hyaluronic acid as part of your skincare routine. Apply the retinol first, allowing it to fully absorb. Follow with the HA serum to replenish moisture.
What’s better: sodium hyaluronate or hyaluronic acid?
Sodium hyaluronate is a salt derived from hyaluronic acid. They provide identical benefits, but sodium hyaluronate may be more easily absorbed into the skin.
Can I use hyaluronic acid with my moisturizer?
Yes, use your hyaluronic serum first, then follow up with moisturizer. The HA will help the moisture penetrate deeper and prevent product loss at the skin's surface.
