First of all, it needs to be clear that medical active collagen is only for external use or injection, and it is almost impossible for oral collagen products to contain medical active collagen, because gastric acid in human digestive system will destroy the protein structure of medical active collagen and greatly reduce its nutritional value.
1, depending on the price, there is something fishy about low prices.
Due to high production standards, strict technical requirements and high cost of low-temperature storage, the price of medical active collagen is not low. The market price of general 1ml medical active collagen is around 300 yuan, so the price is too low, either hydrolyzed collagen with low nutritional value or fish skin collagen with low raw materials.
2, look at the storage temperature, low-temperature storage is true.
Medical active collagen is very sensitive to the preservation environment temperature, just as eggs will mature and deteriorate at high temperature, they still retain bioactive medical active collagen and will inevitably deteriorate at high temperature. Generally, medical active collagen products will be stored at low temperature, indicating that the optimal storage temperature is basically below 38℃.
Some cheap collagen products, in order to confuse people, will also be written on the packaging to be preserved at low temperature, but after being really preserved at low temperature, the essence will be solidified when taken out, but it will clog pores when used, which requires special attention.
3. Look at the product ingredients
In the past, the quality of the essence was ok, but now more and more chemicals are added, and the quality of the essence is easy to be imitated and difficult to be recognized by the naked eye, so this method is not recommended.
Real medical active collagen is easily flocculated with other additives, such as hormones, antibiotics, spices, alcohol and so on. Just as protein will deteriorate when it encounters heavy metals, strong acids and strong bases, medical active collagen will react when it encounters such additives.
Therefore, the ingredient list of real medical active collagen products will be very simple. Of course, skin care products such as lotions and creams are more sticky, so the list of ingredients will be a little more complicated than toner, toner and mask essence.
