Hyaluronic acid: Hyaluronic acid is a naturally occurring and indispensable sodium hyaluronate in human tissue. According to its molecular weight, it can be divided into three types: small molecule hyaluronic acid, medium molecule hyaluronic acid and large molecule hyaluronic acid.
Small molecule hyaluronic acid
The molecular weight is between 10KDa-500KDa, suitable for injection into the surface of the skin to fill fine wrinkles and depressions, replenish lost collagen and elastin, and help the skin restore moisture and smoothness.
Medium molecule hyaluronic acid
Hyaluronic acid with a molecular weight between 500KDa-2000KDa has a slightly soft texture and is suitable for filling nasolabial grooves, lips, tear grooves, and solving problems such as static wrinkles and collagen layer breaks to improve facial contours.
Large molecule hyaluronic acid
Hyaluronic acid with a molecular weight of more than 2000KDa has a relatively hard texture and a long-lasting effect, suitable for facial contour shaping.
What is collagen? Collagen is a composite collagen that reshapes the fiber structure of the skin by supplementing, guiding, stimulating, and rebuilding collagen fibers, promoting the synthesis of new collagen, and promoting the regeneration of new tissue.
The collagen in the skin is mainly composed of type I and type III collagen, of which type I collagen accounts for about 80%-85% and type III collagen accounts for about 10%-15%.
Type I collagen
Provides a strong support structure and support. When type I collagen is lost, it may cause facial wrinkles and depressions.
Type III collagen
Type III collagen, also known as “baby protein”, provides elasticity and stress resistance to the skin. It is mainly used to repair the skin barrier, build a healthy sebum membrane, and help the skin restore its translucent, delicate and plump state.
What is the difference between hyaluronic acid and collagen?
Hyaluronic acid and collagen are both cosmetic methods used to fill wrinkles and repair facial defects. There is no difference between them. The choice should be determined according to personal actual situation.
1. Different anti-aging principles
Hyaluronic acid: maintains skin moisture, increases subcutaneous tissue volume, fills sunken fine lines, and makes the skin plump again and show youth.
Collagen: replenishes lost collagen, improves skin quality, makes the skin firm and moisturized, and stimulates the regeneration of its own collagen and fibroblasts.
2. Different efficacy characteristics
Hyaluronic acid: Hyaluronic acid can be divided into large, medium and small molecular weights. Low molecular weight hyaluronic acid has a deep moisturizing effect, medium molecular weight is used to fill soft tissue and reduce wrinkles, and high molecular weight is suitable for shaping and filling.
Collagen: used to fill the sunken area of the skin, increase tissue volume and have good adhesion, which helps to improve sagging skin, enhance skin firmness and reduce wrinkles.
Tips: When injecting hyaluronic acid, avoid the tear trough and the area around the eyes.
3. Different functions
Hyaluronic acid: It not only helps maintain skin elasticity, but also captures and locks a large number of water molecules, and has excellent moisturizing and lubricating effects, making the skin look full, young and elastic.
Collagen: As a biological polymer protein, its main component is animal connective tissue, which has the triple anti-aging functions of support, repair and protection.
4. Suitable for different skin types
Hyaluronic acid: Good at moisturizing and nourishing, suitable for dry and fine-line skin.
Collagen: Good at repairing tissue cells, suitable for damaged and aging dermis skin.
5. Different maintenance time
Hyaluronic acid: The maintenance effect of hyaluronic acid of different brands varies depending on molecular weight and cross-linking degree. Generally, a single injection of hyaluronic acid with a larger molecular weight can last from 6 to 12 months.
Collagen: Generally speaking, the effect of collagen lasts for about 3 to 6 months. However, this maintenance time is affected by individual differences and living habits, so multiple injections may be required to achieve better results.
How to choose between hyaluronic acid and collagen?
In terms of filling effects, hyaluronic acid and collagen have their own characteristics. After collagen filling, the skin will become firmer and more elastic because it can stimulate the regeneration of collagen inside the skin. Hyaluronic acid is more focused on filling wrinkles and depressions, making the facial contour more three-dimensional.
In addition, the choice of filling material also needs to consider personal skin quality and needs. If the skin is loose and sagging, collagen may be more suitable; if there are more wrinkles and depressions on the face, hyaluronic acid may be more in line with your needs.
