As the saying goes, women are made of water. Only
when the skin contains enough water will it appear bright, fair, and have
sufficient metabolic capacity and ability to withstand external damage.
Whether it is whitening, acne, oil control,
freckle, anti-aging, it must be done on the basis of no water shortage. The
most directly related to skin moisture is “hydration” and “moisturizing”. But
you know “replenishment” and “moisturizing”, which one is
more important? Is it more effective for the skin?
Which is more important for hydrating and
[01. Hydration and moisturizing are two different
In the eyes of many people, hydrating and
moisturizing are one thing. In the skin care counter sales staff, hydrating and
moisturizing are words that can be replaced with each other, which can make the
But I have to tell you that the two of them are
really two different things.
Replenishment of water emphasizes the
“supplement” of water from the outside world into the skin. Representative
behaviors include spraying, applying toner, applying mask, wet compress, etc.;
Moisturizing emphasizes that the skin helps the
skin to “lock” the moisture of the surface, so that the moisture does not drain
and the skin remains moist. Representative behaviors include applying lotion
and applying cream.
Replenishing water is like adding water to a
bottle, while moisturizing is to seal the mouth of the bottle.
In everyday skin care that everyone can do,
hydration is not necessarily necessary, but moisturizing is a must.
Replenishing water without moisturizing skin care, spending more money is no
[02. Replenishing water, not filling deep into
Why is it that hydration is not necessary? The
answer is simple.
Because the daily so-called “hydration”
behavior, in fact, can not really add water to the deep layers of the skin, can
only stay in the stratum corneum of the skin – because our skin has a skin
barrier, it protects our skin from being affected The outside bacteria,
pollution, and harmful substances are harmed, but the external water and
nutrients cannot be easily added to the skin.
If there is no skin barrier, we usually swim,
will not bubble like a steamed bun? Didn’t accidentally get some ketchup on
your face, can the sauce not penetrate the skin?
Therefore, “hydration” can only make
the stratum corneum cells briefly absorb water. But it won’t take long for the
water to be lost and the skin to be returned. (Unless you use a needle-free
water, iontophoresis, water-light needle and other methods to introduce
moisturizing ingredients into the deeper layers of the skin, that is effective)
But the moisturizer is different.
[03. Moisturizing is an essential skin care step]
In fact, our skin has a very perfect moisturizing
The dermis is the water source, which has a water
content of about 70%, which will continuously supply moisture to the skin’s
epidermis. (In the absence of collagen, hyaluronic acid, the water content of
the dermis will decrease, so to a certain age you want to freeze the age, you
may need to make up the hyaluronic acid)
Under the protection of the skin barrier, the
moisture loss of the skin is controlled at a reasonable speed, so that the
water content of the stratum corneum can be maintained between 10% and 20%, and
does not become particularly dry.
However, when the environment is particularly
dry, or the skin barrier function is weakened and damaged, the skin TEWL
(transepidermal water loss rate) value becomes larger, the skin loses water
faster, and the skin appears dry, dull, and desquamation. And so on.
So if you want the skin not to dry, the most
important thing is to lock the water and ensure that the skin does not lose
[04. The hydration does not lock the water, and
the money is more white.]
In the summer, everyone likes to prepare a bottle
of moisturizing spray. When you feel your face is dry, you will take it out and
spray it. But if you don’t follow the subsequent moisturizing steps, you will
find that after the spray is dry, the skin will become drier before it is
sprayed. This is actually the relationship that the added water is not locked
and lost. Therefore, in daily skin care, after applying the mask, applying the
toner, and spraying the spray, you should pay attention to apply a little
lotion and mask to lock the moisture.
If you want to hydrate your skin deeply, then we
need some professional skin management or skin care. And you must add
moisturizing after hydrating.
