Of course, although the popularity of skin care concept is relatively high now, and the party and army of ingredients have also risen, most people still don't recognize ingredients, only recognize products and even listen to advertisements.
To know that the current market will seize the needs of consumers, many brands have seized the fact that women are afraid of being "old" and started to capture all major skin care links. There are many anti-aging products on the market now, but few are really effective, so it is more practical to start with ingredients.
Since we want to resist aging, we should choose the anti-aging ingredients in skin care products. Today, e Meijun will tell you about the most common anti-aging ingredients.
1
Vitamin a alcohol
The famous retinol is a derivative of vitamin A alcohol.
Ordinary essence contains 2% retinol (an alcohol).
When alcohol A acts on the skin, it will be converted into acid A, and then the nucleus will strongly send out a series of commands, such as accelerating skin metabolism, replacing old cells with new cells, and acting on fibroblasts to produce more collagen. This will have a good anti-aging effect. The powerful effect of alcohol A may greatly improve the skin in a short time (especially the high concentration of alcohol A).
For example, shrink pores, control oil and acne, and smooth skin. There are many advantages, and three days and three nights can't be finished. You are an all-around player.
But such a good ingredient can also have side effects.
High concentration (above 0.25%) of vitamin A alcohol will cause some adverse reactions: peeling, redness and dryness.
Vitamin A alcohol is photosensitive, so it is not recommended to use it during the day. Even if it is only used at night, it should be strictly protected from the sun during the day.
At the same time, vitamin A alcohol products are easy to be oxidized and have a short shelf life.
Pregnant women are forbidden to use vitamin A alcohol products. If you use a home beauty instrument and are undergoing medical beauty treatment, please also avoid vitamin A alcohol products.

Victory peptide (polypeptide)
High-efficiency firming concentrated solution
Protein, a small molecule existing in skin and human body, is a very small molecular weight substance (molecular weight is about 1000 dalton) composed of several amino acids after hydrolysis of protein, with stable properties and easy absorption by human body. Now it is widely used in the field of skin care products. Its main function is anti-aging and firming the skin. But it should be noted that different peptides have different effects on the skin when knocking on the blackboard here!
What dipeptide, pentapeptide, hexapeptide, etc. As you can see in the composition table. They are all different kinds of peptides.
Peptides are not cheap and are generally not added to low-end skin care products.
However, the anti-aging effect of "advanced" peptides is not achieved overnight. It takes a certain period of action of at least 4 weeks, and it may take several months to see the anti-aging effect with the naked eye. Therefore, daily use of skin care products containing peptides should be adhered to for a long time. Finally, the combination of peptide and other functional components can increase its ability to penetrate the skin and maximize its anti-aging effect. For example, the combination of palmitoyl pentapeptide -4 with nicotinamide and panthenol is far more effective than any single component in anti-aging and whitening.
three
vitamin C
Vitamin C is a popular ingredient in beauty care, and it is the main antioxidant in the body.
Vitamin C can promote the proliferation of collagen, repair the damage of ultraviolet rays to the skin, reduce and dilute melanin, and alleviate the inflammatory reaction of the skin. It is regarded as a sacred product for anti-wrinkle, anti-aging and whitening.
However, vitamin C is extremely unstable, easily oxidized and discolored, and has strong irritation, so it is not suitable for all skin types.
four
tocopherol
Vitamin E is a powerful antioxidant and belongs to fat-soluble vitamins. Mild and non-irritating, the concentration is usually between 0. 1 ~ 20%.
At present, medical literature has confirmed that it can strengthen skin moisturizing ability, reduce ultraviolet damage and strengthen cell antioxidant ability, and its antioxidant effect will be better when combined with vitamin C.
Vitamin E can also improve hair loss, and it is also helpful for wound healing and scar prevention of patients after surgery or trauma.
five
nicotine
That is, dimension B3. Most people know it because it is a famous whitening ingredient.
Vitamin B3 plays a very important role in human body, and many enzyme biochemical reactions in the body need the help of vitamin B3. However, the earliest application of anti-inflammatory vitamin B3 was not anti-aging, but whitening. Recent studies have proved that it also has a good effect in inhibiting melanosis and anti-inflammation.
A small white bottle of Olay with nicotinamide as the main component.
Based on this feature, the application of nicotinamide in the field of cosmetics has been further extended.
Nicotinamide can maintain skin moisture content and promote dermal microcirculation. Nicotinamide can also greatly reduce or eliminate skin aging, such as wrinkles, peeling, large pores and so on. Reduce the damage of free radicals to the skin, prevent aging, repair the skin and reduce facial dullness.
It can also promote blood circulation of hair follicles and prevent hair thinning and alopecia.
six
Bosein
Bosein is a xylose derivative, which is called hydroxypropyl tetrahydropyranol in slang. Look for this name in the ingredient list.
L 'Oreal Repair Optical Double Tube Essence
There is something called mucopolysaccharide in our skin, which can lock in moisture and prevent the skin from losing water. At the same time, they will form a whole network structure, making the skin firm and elastic. With the increase of age, this mucopolysaccharide will decrease, so Bosein can promote cells to produce this mucopolysaccharide, which can not only moisturize, but also promote the formation of collagen. This ingredient is the patented technology of L 'Oré al Group, so far only L 'Oré al products have this ingredient.

other
Of course, there are many antioxidants, so I won't introduce them one by one. Such as green tea extract, soybean extract, superoxide dismutase (SOD), metallothionein (MT), astaxanthin, fullerene (C60), glutathione (GSH), thiotaurine and selenomethionine.
Finally, it is also hooliganism to look at the ingredients without looking at the dosage and products. After all, international practice requires all skin care products to be clearly marked with ingredients. Many so-called cheap alternative versions are just imitations of ingredients, in order to let people find their similarities quickly. The specific dosage, the interaction between the added components and the purification process are the core of each family.
