Collagen - Basic Knowledge
The main physiological function of collagen in the skin is to act as an adhesive for connective tissue, retaining water in the dermis. It is the main substance that provides moisture to the skin connective tissue, maintains elasticity and firmness. In other words, it is the scaffold and water reservoir of cells.

Double skin beauty original collagen effect
| Replenish skin nutrition | More than 80% of the skin is composed of type I collagen, which provides the amino acid nutrients needed for skin repair and maintains skin youthfulness. |
|---|
| Improve skin tone and texture | The amino acids produced after collagen degradation can effectively inhibit tyrosinase activity and reduce melanin production. |
|---|
| Improve skin and soft tissue laxity | Directly replenish collagen, provide the skin with a high-quality tissue environment, promote fibroblasts to grow collagen and elastic fibers, and restore skin firmness. |
|---|
| Facial contouring and beautification | The high viscoelasticity and cohesive properties of collagen can effectively achieve high-quality retention in the skin, provide good support, and prevent displacement. |

The following situations are not suitable for collagen injection:
1. The doctor assesses that the patient's condition is not suitable for implantation.
2. People with autoimmune diseases, keloids or severe allergies.
3. Patients with known allergies to collagen, including (but not limited to) those who have used collagen products such as injections, implants, hemostatic cotton, sutures, biological glue, etc. and have experienced obvious allergic reactions.
4. Those who are known to be allergic to anesthetics such as lidocaine.
Not for use in breast augmentation or as an implant in bone, muscle, tendon, ligament or muscle.
The safety of use in pregnant women, breastfeeding women and children has not been evaluated.
This product is used in patients taking anticoagulants such as aspirin and nonsteroidal anti-inflammatory drugs, which may increase bleeding at the implant site.
1. From the day of injection to 2 days: avoid eating seafood, alcohol, spicy and irritating foods; avoid using cosmetics.
2. Within 1 week after injection: It is recommended to strengthen skin care and repair; do not massage the injection site vigorously.
3. Within 2 weeks after injection: Maintain a normal work and rest schedule; avoid exposure to sunlight and high temperature environments (such as hot springs and ovens).
4. Within 1 month after injection: Do not take a sauna.
5. Avoid staying up late, smoking, drinking, and excessive exposure to strong sunlight or other rays.

Sunmax's R&D team used complete tyrosine removal technology to successfully remove the telopeptide, which is prone to allergies. The amino acid sequence of collagen without telopeptides is over 99.99% identical to human collagen, significantly alleviating concerns about immune system problems.
- Initial stage: The effect is immediate after injection, immediately filling the lost thickness and volume of the dermis.
-Mid-term: About 3 to 4 weeks after surgery, collagen is fixed in the skin and integrated with human tissue to form a soft scaffold for the skin, supporting the loose skin.
- Late stage: About 4 weeks after the operation, the collagen will appear to have slightly subsided, but in fact it has not disappeared. Instead, it has been absorbed by the body tissues. The collagen will be degraded into amino acid nutrients, allowing the body's fibroblasts to multiply and grow in the network structure scaffold formed by the collagen, achieving the effect of firming, radiant, moisturized, elastic and youthful skin.
(The above results are based on clinical observations. In reality, there may be slight differences depending on individual constitution, lifestyle habits, etc.)
The two are structurally different. The collagen network structure is the "steel scaffold" that supports human skin; hyaluronic acid is expandable and plastic, and is the "cement" that fills the depressions in human tissues. After the steel scaffold is constructed, the cement is filled in to avoid causing landslides and displacement.
