If you don't exfoliate for a long time, it will bring skin problems such as dark skin, large pores, closed acne, and not easy to absorb. To help the skin breathe better, we need to exfoliate.
What is horny?
In fact, our skin has many layers, the stratum corneum is our first layer of skin, it is also a barrier, the stratum corneum will age and renew, and the renewal cycle is about 28 days.
Is horny garbage to be removed?
If you want to take a shower, you will find the inner thighs. Ankle is especially abundant (also known as old mud), and it happens every day. These are the wastes secreted by the body, and if you don't remove them, you will always feel dirty.
However, horny is aggrieved. It is usually packaged as dead old cells, but the stratum corneum is a living system!
The stratum corneum protects the skin from environmental irritants and also stores water. Without the stratum corneum, your skin cells can quickly dehydrate and die!
The cuticle is as important as anything in the body, so we should protect it and control it! If you want to remove it, do it in moderation.
Frequent exfoliation and a little observation with a magnifying glass is equivalent to crushing the skin. The skin loses moisture easily, and the skin is prone to dryness and sensitivity.
Should dull skin be exfoliated?
If you think your skin is dark, don't rush to exfoliate, wash your face first, then apply the mask to see if there is any whitening and lightening. The facial cleanser also has a certain effect of removing keratin, and moisturizing is actually moisturizing the stratum corneum. After cleansing and moisturizing you are still not satisfied, the next step is exfoliation.
How to judge whether to exfoliate?
Cleansing and moisturizing are done, can be skin still dull, rough, with acne and blackheads, then you can consider exfoliating.
So not everyone has to exfoliate, like doing moisturizing and cleansing, the forehead, nose, chin, still rough, will exfoliate these parts.
Can sensitive skin be exfoliated?
Sensitive skin also exfoliates, do you think your skin is not sensitive enough?
Everyone must pay attention! Horny is a good thing, it's not the same as melanin! You can exfoliate every day, but not exfoliating!
The top priority for sensitive skin is "protecting keratin", keratin is the outermost barrier to the skin, the horny layer of sensitive skin is very thin, you still have to exfoliate the remaining keratin, can't you be sensitive?
Can acne skin be exfoliated?
Acne-prone skin pairs well with some chemical exfoliants that can exfoliate at the same time as acne and control oils, such as salicylic acid. However, scrubbing acne-prone skin with physical particles is not recommended as the particles can easily damage the skin surface and make acne worse.
What is the principle of exfoliation?
There are two principles, chemical removal and physical removal, similar to chemical sunscreen and physical sunscreen.
Chemical Exfoliation: Uses acidic ingredients or enzymes to soften and accelerate keratin metabolism. For example, fruit acid, salicylic acid, fruit enzymes, etc.
Physical Exfoliation: Uses plant, plastic, mineral particles to grind the keratin from the skin's surface. For example, the face wash is a scrub along with sea salt.
How often can exfoliate?
The skin's renewal cycle is about 28 days, and frequent exfoliation can destroy its own protective barrier. When the stratum corneum is too thin, when there is too little normal keratin, the skin is especially vulnerable to external damage. At this time, there may be problems such as itching, redness, allergies, etc. Therefore, exfoliation should be appropriate and not frequent.
First, the keratin cycle is different for different skin types.
Oily skin: thick stratum corneum, oily, once a week.
Dry skin: slow metabolism, 1 month/time.
Sensitive skin: thin, poor skin resistance, try not to exfoliate.
Combination skin: need to exfoliate once a week, T-zone once a week, cheeks 2 weeks/time.
Secondly, different parts of the face are also zoned care:
T-zone: It is the easiest to accumulate keratin and needs to be cleaned up.
U area: Gentle circular massage is enough.
Of course, skin moisturizing care must be done quickly after exfoliation to avoid skin damage that can lead to dryness and sensitivity.
Which ingredients can exfoliate?
Whether or not there is an exfoliating feature in the product, let's see if there are any of the three types of ingredients mentioned below.
Acids: salicylic acid, fruit acid
It is recommended to have fruit acid because of its strong penetrating power. In addition, many people will use salicylic acid for allergic effects, and low concentrations of salicylic acid can even cause keratinization.
There are many kinds of fruit acids, all derived from all kinds of delicious things. It is commonly used for sugar cane in sugar cane, lactic acid in yogurt.
Salicylic acid is better for cleaning pores because it dissolves with oil, antibacterial and anti-inflammatory action, it is a good choice for acne treatment ~ but it has nothing to do with exfoliation.
Enzyme: papain
Enzymes can decompose dead skin and skin tissue, and the amino acids formed after decomposition can also nourish the skin.
A commonly used enzyme is papain. An "enzyme" is usually very principled, and it is targeted, only a certain substance is effective. However, papain is particularly atmospheric, and not fussy, and can break down basically any protein.
Scrub: common silicon, sodium bicarbonate, corncob, peach seed powder, brown sugar, etc.
The principle is very simple, that is, rubbing, similar to toothpaste to clean the teeth.
Protease products are recommended for dry skin or sensitive muscles, these ingredients are milder.
Fruit acid is more recommended for oily skin, the effect is remarkable.
