Collagen has gained significant popularity among beauty-conscious women. The market offers numerous collagen drinks and powders, and some women even opt for collagen injections. It's understandable that many women remain skeptical.
Some basic facts about collagen?
1. Consuming collagen does not equal replenishing collagen
Many foods contain abundant collagen. After digestion and absorption in the gastrointestinal tract, it exists in the body as amino acids and forms the proteins our bodies need.The collagen you consume is not the same as the collagen in your body. The collagen in your body is primarily synthesized by cells and has no connection to the collagen you eat. Collagen exists only in animals and humans; no plants contain any collagen whatsoever. Any health supplement claiming to contain plant-based collagen is a complete deception.As a food additive, collagen is primarily extracted from animal skin, tendons, and bones. It is added to products like ham, yogurt, and milk beverages. The main component of viscose is collagen; fundamentally, there is no difference between the two, only slight variations in extraction methods and solubility.
2. Is Topical Application of Collagen Effective?
Structurally, the human skin's surface layer is extremely dense. It contains keratin that protects the skin. While pores remain open to allow respiration and secretion by sebaceous and sweat glands, and to absorb small molecules, the skin cannot absorb any large molecules—especially macromolecules like proteins.Therefore, theoretically, applying collagen skincare products merely deposits collagen on the skin's surface layer. It cannot penetrate into the dermis. Repeated application may cause skin allergies, leading to localized itching or rashes. Additionally, it may create a dependency on the skincare product.
3. Is Collagen Injection Reliable?
When performed by experienced physicians at reputable medical aesthetic clinics, collagen injections can effectively reduce facial wrinkles or fill localized depressions. Once injected, part of the collagen is absorbed by the body while the remainder provides a filling effect. This results in temporarily plumper, smoother skin. However, the procedure is costly and its effects are short-lived.Approximately 10% of individuals may experience allergic reactions, necessitating injections at hospitals with advanced technology. Effects typically last only about six months, requiring repeat injections.
Friendly Reminder
Decide whether to undergo collagen injections based on your specific circumstances. Individuals prone to scarring or allergies should avoid injections, as they may exacerbate allergic reactions, cause facial swelling, and reduce absorption efficiency.
