......
Yikes! wait! Don't look at the brush acid is blown so well, but not everyone is suitable, if the method is not right, waiting for you may be a bad face.
In order to prevent everyone from blindly brushing acid, today we will talk about brushing acid.
After reading this article, master the skills of scientific brushing acid, you can appreciate how fragrant brush acid really is!
<h1 class="pgc-h-arrow-right" data-track="16" >. Are the various effects of the web transmission real? </h1>
Most of the acid brushing effects transmitted on the Internet are true.
First of all, brush acid can effectively relieve acne.
Acne is due to excessive secretion of sebum, and horn plugs formed by mixed keratin block the pores, resulting in a large number of anaerobic bacteria (Propionibacterium acnes) in the pores to produce inflammation, which is commonly known as acne. Acid dissolves excess keratin on the surface of the skin, unclogs pores, and allows sebum to flow out normally. The pipes are unblocked, and the acne is naturally reduced.
Brushing acid can also speed up the metabolism of the skin, making the skin look delicate and smooth.
In addition, brush acid can also take away a part of the melanin of the stratum corneum, to achieve the effect of whitening the skin and lightening acne scars.
<h1 class="pgc-h-arrow-right" data-track="28" >2, who can brush acid? Who is not suitable? </h1>
Although the effect of acid is good, it cannot be abused. If you want to brush acid, you must first find out whether you are suitable or not.
The following cases are more suitable for brushing acid:
Excessive oil secretion leads to acne muscles, mouth closure
Acne scars
The skin is rough and dull
Enlarged pores
Perimeter keratosis
chloasma
Rosacea (it is not recommended to brush yourself at the beginning, it is recommended to find a doctor to brush acid as appropriate after the consultation)
But there are some skin types that are not suitable for brushing acid, and blind attempts can lead to damage to the barrier:
Sensitive skin
Skin with damaged barrier
Severe redness on the skin
People who are allergic to acid products
Here is a special reminder, if you are a long acne caused by damaged barrier (usually accompanied by more serious red blood, skin peeling), then do not try to brush acid!
At this time, maintaining your own skin barrier is the first priority, and skin care products are also as gentle as possible.
<h1 class="pgc-h-arrow-right" data-track="51" >3. Can you brush acid at home? </h1>
Yes, provided that the right acid is chosen.
We often say that brush acid can be divided into 2 categories.
We interviewed some friends who have brushed acid at both institutions and at home for your reference:
Overall, if your skin problem is not too serious, only occasionally long mouth closures, acne, as long as you choose the right acid, then you can brush acid at home.
Severe acne muscle, household acids may not have much effect on you, it is recommended to go to the hospital for treatment, under the operation of a professional to choose a high concentration of acid.
You can also consider the status of your wallet, and the two work together.
Some small partners may buy some high concentrations of foreign household acids through channels such as sea tao and purchasing, which have high technical requirements for operation, and we do not recommend that novices use such acids with such high concentrations.
If you have a little experience in brushing acid, you should also pay attention to the concentration and type of acid, the general concentration of more than 10% is more exciting, must not stay too long.
<h1 class="pgc-h-arrow-right" data-track="77" >4. Will brushing acid make the stratum corneum thinner? </h1>
Brushing acid correctly will make your old keratin fall off in the short term, but in the long run, it will make your cuticle more healthy and will not become thinner.
However, if you brush too often, it can really thin the stratum corneum.
What is the right frequency, we will talk about it later.
<h1 class="pgc-h-arrow-right" data-track="82" >5, what acid should be chosen for different skin? </h1>
It's time to brush the most tangled part of the acid party:
I know that I am suitable for brushing acid, but there are too many types of acids on the market, which one am I suitable for?
We have compiled several common household skin care product acids for your reference.
Fruit Acid: Brightens skin tone
Fruit acid is a collective term for a family of organic acids. Because most fruit acids are water-soluble, it acts primarily on the surface of our skin.
Brushing with fruit acid can peel away the waste keratin on the surface of the skin to achieve a smoothing effect. In addition, it can also promote skin metabolism, while inhibiting the production of melanin, to achieve the effect of brightening the skin tone.
We talk about fruit acids in daily life, there are mainly these types: glycolic acid, lactic acid, almond acid, malic acid, citric acid.
In addition, there are gluconolactones, three generations of lactate, and four generations of maltoseic acid, which will be milder than the above fructic acid.
The most commonly used fruit acid in general skin care products is glycolic acid, which has a small molecular weight and is easy to penetrate the skin.
These skincare products feature the main fruit acid ingredients:
Because it is water-soluble, some lotions will also add low concentrations of fruit acid to achieve the effect of micro-exfoliation.
For example, the Lan K Aurora water we evaluated before is added about 2.57% of the fruit acid.
Skin problems are not serious, just want to use acid as a daily maintenance friend, you can consider this kind of acid-containing lotion, they will have lower requirements for operation, side effects will be smaller.
Salicylic acid: oily skin pro-mom
Salicylic acid is fat-soluble and can penetrate deep into the pores to loosen the pore-clogging fat particles; and it has a certain anti-inflammatory effect at low concentrations, which can relieve skin inflammation of acne muscle. It simply solves the root cause of acne and relieves the existing inflammation.
If you are a pox and closed mouth caused by strong oil secretion, then you can choose it.
In addition, the low concentration of salicylic acid also has the effect of two-way adjustment of keratin, which can not only peel off waste keratin, but also promote the regeneration of keratin. It's just a matter of repairing and repairing.
So dry and neutral skin don't have to worry about brushing acid to make the stratum corneum thinner, if you can use it, it can strengthen your stratum corneum.
It should be reminded that salicylic acid has certain risks to pregnant women and fetuses, so pregnant and nursing mothers should not use salicylic acid.
We talk about salicylic acid in our daily life, there are two main types: salicylic acid, salicylic acid derivatives (caprylylsalicylic acid, methyl salicylate, etc.).
These skincare products feature salicylic acid ingredients:
Amygdallic acid: dry skin preferred
Amygdala is also a type of fruit acid. However, it is more special and is fat-soluble.
Because of its large molecular weight, the penetration rate of the skin will be slower, so it will be milder than ordinary fruit acid.
These skincare products feature amygdalaic acid ingredients:
Azelaic acid
Azela acid, also known as rhododendron acid, is used less in skin care products because of some limitations (the concentration required for action is relatively high, the skin feeling is slightly weaker, and the irritation is strong).
About 10% of azelaic acid is not particularly irritating to the skin, if it is used for the whole face, you can choose this concentration. About 20% of the azelaic acid irritation is stronger, if you have this concentration of acid on hand, it is best to apply local acne.
Compound acid: excellent performance in all aspects
Compound acids are generally more than 2 kinds of acids combined, taking into account the advantages of different acids, strengthening the effect, but also to reduce the adverse reactions caused by some irritating acids.
It's like a single ingredient that's hard to make too fancy dishes, but with other foods and spices, you can make all kinds of flavors.
Because of this, the requirements for the concentration ratio of compound acids will be higher, so they are currently used more in medical institutions.
Tretinoin: Not recommended for home use
There is also a class of acids that are used more often than tretinoin.
It has good effects but also large side effects, is a prescription drug, and needs to be carried out under the guidance of a doctor, so we will not go into details.
Friends who want to know whether they are suitable for retinoin, it is recommended that you face the doctor is the most secure.
<h1 class="pgc-h-arrow-right" data-track="143" >6, what to pay attention to when brushing acid at home? </h1>
Brush acid at home, the most important thing to pay attention to is patience, do not think about eating in one breath into a fat man.
The concentration of household acid is low, and it will not be as effective as medical institutions brush acid.
Therefore, some friends will feel that the concentration is not enough/frequency is not enough, excessive brushing of acid, resulting in damage to the barrier, such as the case we mentioned at the beginning:
For novices brushing acid, it is best to refer to the following rules:
(1) Novices who brush acid for the first time are best brushed from low concentrations, and the frequency is controlled once every 2-3 weeks.
(2) The residence time will be slightly different according to the product, it is recommended to brush up with the shortest stay time on the product manual.
(3) After the skin slowly adapts, then gradually increase the concentration/frequency.
Quietly tell you:
Brush acid is not the higher the concentration, the higher the concentration, nor the tingling reaction of the skin, the better, when your skin gradually adapts to the acid at hand, you can appropriately extend the residence time, which can also make the effect better.
Keeping these few in mind, we're ready to start brushing acid.
Cleanse
Try to choose a gentle cleanser. If a cleansing mask is used, it is recommended to wait a week before brushing the acid.
Prepare before brushing acid
Before brushing the acid, it is best to apply some behind the ear to observe whether there is an allergic reaction.
If you first use a product with good closure to apply to the nose, around the eyes, near the corners of the eyes, such as vaseline, moisturizing cream. This part of the skin is more sensitive, and it is recommended not to touch acid.
When brushing acid
When brushing acid, follow the order of first forehead + T zone, then cheeks, and then the whole face. This is because the forehead and T zone are more tolerant, and the time will be more controllable from brushing from here.
If you only have a local (such as forehead, nose) problem is more serious, then only brush the part, do not be greedy.
After brushing acid care
After brushing the acid, first stop the functional products on hand, these ingredients generally have a certain irritation, may cause skin allergies, moisturizing is the focus of the current skin care.
Moisturizing masks and moisturizing creams can be arranged, and the cleansers should also try to use mild cleansers as much as possible, avoiding cleansers with scrub particles.
Since acid will take away some of the waste keratin, ultraviolet rays will be more likely to hurt your skin, so do a good job of strict sun protection for a week after brushing acid. Try not to brush acid during the day, choose to use it at night.
Sunscreen is recommended to choose pure physical sunscreen.
Friends who don't know which sunscreen is milder, you can poke here to see our review last year:
Heavy! 618 super sun protection raiders! Which of the 23 Popular Sunscreens is Worth Buying?
In addition, some slight bursting, tightness, peeling, and flaking are normal phenomena.
The burst is caused by the shedding of the stratum corneum, the angle plug that blocks the pores is exposed, and the inflammation is caused by a short period of time. The acid will gradually resolve after brushing for a period of time.
The latter can also be relieved as long as it is moisturized.
However, if your skin has obvious intolerance, such as redness, tingling, large-scale peeling, scabs, it means that this acid is not suitable for you, the concentration is too high, it is recommended to stop it first.
The above is our brush acid guide.
When writing this popular science, we had an exchange with a doctor in the aesthetic industry. He mentioned that the cases of bad faces caused by excessive brushing acid and wrong brushing acid are no less than the cases of problems with the skin itself.
Therefore, although it is good to brush acid, it is also good to do enough homework.
Friends who want to try to brush acid, remember to like the collection forward ~ ~
