As we all know, high-end cosmetics, especially face creams and eye creams, like to give everyone some special massage techniques.
As a straight man, I often can't understand it, because the massage techniques are different from each family, and the more high-end the technique, the more complicated it is.
Who is this thing for, and is it useful? Anyway, the sense of ritual is full ......
However, I recently saw a **, which talks about the relationship between the penetration of active substances in massage and skin care products, which opened my eyes and discovered a new world.
It turns out that whether the massage is done or not, how the technique is, etc., can affect the infiltrationAfter that, it will be convenient, and after applying the product, hurry up and make yourself a horse to kill a chicken!
Different active ingredients and different research methods have been studied, as well as different dosage forms (lotions and creams), and it seems that it is still relatively well considered.
In terms of active ingredients, I picked water-soluble caffeine and fat-soluble rhododendron alcohol (strange, why this whitening ingredient is banned and still experimenting).
Then the massage technique is also chosenMassage in the direction of hair growth and in the direction of hair growth, as well as in a circular motionThree kinds.
As for why these techniques were chosen, it is estimated that they were to study the effects of hair follicle penetration.
The final results showed that water-soluble caffeine can be massaged to increase the degree of penetration.
And after massage, it can be detected in both the epidermis and dermis, but it does not seem to have a direct effect on oil-soluble rhododendron alcohol.
The technique is also very interesting, it talks about the best effect in the direction of hair growth, and it is useless to massage in circles or follow hair growth, and the effect can vary by about 2-3 times at most.
In additionThe penetration of lotions is higher than that of creams……But the formula of these two products is different, so it's hard to say why.
Why does it work against the hair?
The article mentions that pressing and pulling against the direction of the hair is most likely to change the structure of the hair follicle, causing the hair follicle orifice to expand, and caffeine can enter through the hair follicle orifice.
The hair follicle orifice is the hole where the hair grows**, and it is also a way for drugs to penetrate, when the hair follicle orifice becomes larger, more drugs can penetrate through this route**.
This is understandable, as caffeine is a water-soluble ingredient that has a hard time crossing the lipid barrier of the stratum corneum, so there must be other ways to get in.
Rhododenol is an oil-soluble ingredient, its penetration is through the stratum corneum, and it will not be affected much by the size of the hair follicle orifice, and its natural penetration ability is already very strong.
Rhododendron alcohol is about ten times more penetrating than the original caffeine)
Although when we pet the cat, we need to stroke in the positive direction, that is, in the direction of the hair, the cat may bite you in reverse, but when massaging, we need to go against the hair, so that we can penetrate more!
In other words, is it only such a massage technique that can accelerate the penetration? Not necessarily!
Let's take a look at the latest literature, this time it is about the promotion of tretinol penetration, although tretinol is a fat-soluble ingredient, but there are still people who want to improve its penetration, what to do, massage!
In this article, the author has devised two massage methodsOne is a rotational massage and the other is a rolling massage
This rotary massage may simulate the method of using our fingers to massage, while the rolling massage is similar to a beauty instrument.
In the end, it was found that the effect of rolling massage is better, if you continue to massage for 60 seconds, you can double the permeability, so the affordable method, it is estimated that it will be promoted in the future!
The simplest rolling massage instrument is this product, Zhen Huan has used it in the biography, and now it is very popular abroad, in fact, the cheap one is only a few yuan a piece, and the expensive one will probably not exceed 50 yuan.
After using the skin care products, rolling around, maybe the effect will be better, maybe there is no need to sell high-end skin care products, just rely on this thing, the effectiveness of anti-aging and whitening will be improved!
So what do these two articles teach us?
It must be useful for massage, and the massage technique should also be paid attention to, and it is necessary to reverse massage or roll massage.
When I have time, I have to see what direction the hair growth on my face is, and it is only effective to reverse it, or just buy a jade wheel to roll around.
Either it's better to rub left and right, at least it's better to rub than not to rub ......
Let's rub our faces!
