What are human stem cell cosmetics?
"Human stem cell cosmetics" are expected to regenerate and rejuvenate the skin.
By using ingredients derived from stem cells extracted from human cells, it is expected that the skin's repair ability will be enhanced and damage caused by aging will be repaired.
Stem cell cosmetics generally do not contain actual stem cells.
Typically, an extract made from adipose-derived stem cells taken from human subcutaneous fat and then cultured is used.
There are three types of stem cells
There are three types: human-derived, plant-derived, and animal-derived.
Human-derived stem cells are cells that naturally exist in the human body and are thought to be highly compatible, leading to more effective absorption into the skin and more effective effects.
Why can skin rejuvenation be expected?
The ingredients contained in stem cell cosmetics activate cells in the epidermis and dermis of the skin, promote the metabolism of old cells, and support the production of new cells.
The result is regeneration and rejuvenation of the skin.
(One case)
・Collagen and elastin
→ Ingredients that support tissue structure
· hyaluronic acid
→ Ingredients that moisturize the skin
・Epidermal growth factor and fibroblast growth factor
→ Promotes skin regeneration and repair , improving skin firmness and elasticity
What are the advantages and disadvantages of stem cell cosmetics?
merit---------
●Promotes skin regeneration
Helps repair and rejuvenate skin
Moisturizing effect
Prevents dry and rough skin, keeping skin soft and smooth
Antioxidant effect
Reduces damage to the skin caused by UV rays and aging, and keeps the skin youthful
Demerit---------
● It's expensive
Due to the rarity of stem cell-derived ingredients and the high cost of the manufacturing process, the price is higher than that of regular cosmetics.
Insufficient scientific evidence
Some products may not have sufficient scientific evidence, so their effectiveness cannot be guaranteed.
What is the difference between stem cell culture medium and stem cell culture supernatant?
■Stem cell culture medium
The medium (a type of nutrient ) in which stem cells are cultured
■Stem cell culture supernatant
A liquid that contains components secreted or released from the culture medium while stem cells are being cultured.
Stem cell culture medium is a nutrient solution for stem cell growth , and stem cell culture supernatant is a liquid containing stem cell-derived components obtained after the medium is removed .
Which one has a better beauty effect?
Stem cell culture fluid also contains many growth factors and is therefore expected to have the effect of revitalizing skin cells, but it is generally believed that stem cell culture supernatant contains more concentrated components derived from stem cells and is therefore likely to have a more direct cosmetic effect.
