＂Olive＂ burst into flames, the legendary ceiling repair, how to choose？
Autumn and winter are coming, the climate is unstable, and it is time for sensitive muscle pain.
In daily life, excessive cleaning will be sensitive, and brush acid will also be sensitive if she is excessive, and sometimes she is sensitive even though she has done nothing.
In addition to repairing the skin wall (barrier), the nursing of sensitive muscles should also put out (suppress) the small fires (inflammatory factors) in the wall from time to time, otherwise, when the small fires become a prairie fire, it will cause thousands of miles of bare land (such as pigmentation and other problems).
Recently, there is an ingredient that is particularly hot-olive leaf extract, which claims to be a soothing and repairing "ceiling". What is the actual effect behind it? How can we choose so many related products? Today, I will take you through an article.
01
What is an olive?
First of all, let’s look at the olive leaf extract, which is actually not the same thing as the olive we eat every day, but the olive (Olea europaea) growing in the Mediterranean region, a famous subtropical fruit tree, which is a long-lived tree.
At present, olive leaf extract mainly has the following functions:
1 Soothes & reduces redness:
According to the data of Hallstar, a well-known raw material supplier, we can see that although it is inferior to dexamethasone (a synthetic corticosteroid), it also has a good inhibitory effect on the expression of IL-1α.
At the same time, from the data given by the supplier, we can see that 1% olive extract can improve the redness and oil secretion of acne muscle in 7 days, so the title of acne muscle mother is not random.
2 anti-oxidation:
Olive leaf extract contains high content of oleuropein (3%-18%), and oleuropein has been proved to have good antioxidant effect by many experiments. However, it should be noted that compared with the preventive effect (applied before being irradiated by ultraviolet rays), it has a better soothing effect (applied after being irradiated by ultraviolet rays).
Nowadays, many people are looking for a milder substitute for C (antioxidant) in morning C and evening A. Olive leaf extract here is not a good substitute, but it is a good hand when used for after-sun repair.
3. Repair:
This is actually the unknown killer of olive leaf extract, which can not only resist oxidation, but also promote PPAR up-regulation.
PPAR is a signal molecule, which is related to the synthesis of lipids and even collagen, thus increasing collagen IV (the main component of basement membrane) and repairing the inner wall of skin (basement membrane).
Of course, the repair of sensitive muscles should not only take care of the inner wall (basement membrane), but also the outer wall (stratum corneum), such as using products containing ceramide and squalane.

How to choose products?
There are many products containing olive leaf extract in the market. How to choose? Let’s talk about it one by one:
Although everyone adds olive leaf extract, their family has its own patent, which is mainly aimed at a series of optimization of the active substance of oleuropein mentioned above. After optimization, the oleuropein component in the raw materials can be stabilized at around 6-10%.
The dosage of the formula reached 10%, much higher than the 1% suggested by the raw material supplier, which may be the reason why it works so well. In addition, the formula also added zinc gluconate for oil control and a small amount of arbutin for whitening.
On the whole, this product is a good choice except that it is expensive and suitable for relieving acne muscles or for fear of causing post-inflammatory pigmentation after using heavy drugs.
CSS, an olive gel, is known as a flat version of Ou Ma. Although the core ingredient is not Omaqiang, the olive leaf extract is directly dried to 19%.
At the same time, Centella asiatica and various peptides are added, which will be more suitable for the soothing use of anti-aging people in general. For example, it is a good choice to form cp with alcohol A.
Yan Yan’s anti-oxygen mada combines soothing and anti-oxidation.
3% ethyl VC+ powder ergothionine (antioxidant devil) forms a circulating antioxidant effect in the epidermis, and you don’t have to worry about skin oxidation and dullness all day;
The callus extract and mosaic extract of Leontopodium alpinum are also added, which are rich in edelic acid and increase the anti-aging function in the direction of strengthening anti-oxidation; Under the action of olive leaf extract, this multi-channel antioxidant combination has become extremely gentle, and it has become a star anti-oxidation and brightening item that sensitive muscles can also use happily.
Mainly 3% tranexamic acid +2% olive leaf extract +1% rhamnose, on the whole, it will be more suitable for dealing with red acne marks, because tranexamic acid itself has a good repair effect, and it is a whitening raw material that Japan likes to use.
This small green bottle of Baizhu Extract is known as colorless and plain, which tastes like a cocktail formula. Anyway, this bottle has all the common soothing ingredients, including chamomile extract, β-glucan, olive leaf extract, etc., and it also adds PCA zinc, which is more suitable for soothing oil skin.
