Hyaluronic Acid: What It Is, Benefits, How To Use and Side Effects
What is hyaluronic acid?
Hyaluronic acid is a substance naturally found in the human body, particularly in the skin, eyes, and joints. It plays a key role in maintaining skin hydration, lubricating joints, and promoting overall tissue health. In skincare, it's often used as a moisturizing ingredient to help retain water and improve skin texture.
What does hyaluronic acid do for you?
Hyaluronic acid provides several benefits:
● Skin Hydration:
It has the ability to retain a large amount of water, helping to keep the skin well-hydrated and plump.
● Joint Lubrication:
In joints, hyaluronic acid acts as a lubricant and shock absorber, contributing to joint health and mobility.
● Wound Healing:
It plays a role in tissue repair and regeneration, aiding in the healing process.
● Collagen Support:
Hyaluronic acid is often associated with collagen production, contributing to skin elasticity and firmness.
In skincare, it's a popular ingredient for moisturizing products, helping to reduce the appearance of fine lines and wrinkles by maintaining skin hydration.
How is hyaluronic acid made?
Hyaluronic acid can be produced through both natural and synthetic processes.
Natural Production:
■ Biofermentation:
Bacteria such as Streptococcus zooepidemicus are commonly used to ferment a sugar substrate (usually glucose) to produce hyaluronic acid.
■ Extraction from Rooster Combs:
Historically, hyaluronic acid was extracted from rooster combs, but this method is less common now due to ethical and practical considerations.
Synthetic Production:
■ Extraction from Bacteria:
Genetically engineered bacteria can be used to produce hyaluronic acid in large quantities.
■ Chemical Synthesis:
Chemical methods can also be employed to synthesize hyaluronic acid, although this approach is less common.
Most commercially available hyaluronic acid used in skincare and medical applications is produced through biofermentation or bacterial expression methods.
Is hyaluronic acid safe?
Yes, hyaluronic acid is generally considered safe for use in skincare and medical applications. It is a naturally occurring substance in the human body, which reduces the risk of adverse reactions. In skincare, hyaluronic acid is commonly used for its moisturizing properties and is well-tolerated by most skin types.
However, as with any cosmetic or medical ingredient, individual reactions can vary. It's always a good idea to perform a patch test when trying new skincare products to ensure you don't have an adverse reaction. Additionally, if you have specific concerns or medical conditions, it's advisable to consult with a healthcare professional before using products containing hyaluronic acid.
How does hyaluronic acid interact with other products?
Hyaluronic acid is generally compatible with a wide range of skincare products. It plays well with other ingredients and can be incorporated into various routines. Some considerations:
● Layering:
Hyaluronic acid is often used as a hydrating serum and can be applied before heavier creams or oils in your skincare routine.
● pH Compatibility:
It is versatile and tends to work well across different pH levels, making it compatible with various skincare formulations.
● Active Ingredients:
Hyaluronic acid is typically safe to use with other active ingredients like retinoids or vitamin C. However, individual skin sensitivity varies, so it's advisable to introduce new products gradually.
■ Moisturizers:
It pairs well with moisturizers, enhancing their hydrating effects.
● Sunscreen:
Applying hyaluronic acid before sunscreen helps maintain skin hydration, especially important if you're using sunscreens that may be drying.
Remember to follow the specific instructions provided by the products you're using and consider your skin's unique needs and sensitivities.
How can I take hyaluronic acid?
Hyaluronic acid is commonly used topically in skincare products, but there are other ways to incorporate it into your routine:
■ Topical Skincare:
Look for moisturizers, serums, or creams containing hyaluronic acid. Apply these products to clean, damp skin, and follow up with your usual skincare routine.
■ Dermal Fillers:
In a medical setting, hyaluronic acid is used as a dermal filler to reduce the appearance of wrinkles and add volume to specific areas of the face. This should be administered by a qualified healthcare professional.
■ Oral Supplements:
Hyaluronic acid supplements are also available in oral form. These supplements are claimed to support joint health and skin hydration. However, the effectiveness of oral hyaluronic acid supplements is a subject of ongoing research, and it's advisable to consult with a healthcare professional before taking them.
Remember, for skincare products or supplements, it's essential to follow the recommended usage instructions and consult with a healthcare or skincare professional if you have any concerns or specific health conditions.
How does hyaluronic acid work?
Hyaluronic acid works primarily by attracting and retaining water. Here's how it functions:
● Hydration:
Hyaluronic acid has a unique ability to hold a significant amount of water—up to 1,000 times its weight. When applied topically or injected, it draws moisture into the skin, helping to hydrate and plump the skin cells.
● Skin Barrier:
By maintaining skin hydration, hyaluronic acid contributes to a healthy skin barrier. This barrier helps protect the skin from external factors like pollutants and helps reduce water loss.
● Collagen Support:
It is also believed to play a role in collagen synthesis, promoting skin elasticity and firmness over time.
● Joint Lubrication:
In joints, hyaluronic acid acts as a lubricant and cushion, contributing to joint mobility and comfort.
Whether used in skincare products or as dermal fillers, the goal is to improve skin hydration, reduce the appearance of fine lines and wrinkles, and support overall skin health.
