Water needle is a beauty method used by more and more people now. After water injection into the dermis, the skin will become very moist and shiny, but you should also pay attention to skin care after water injection. So, what is the function of water needle? How long can the effect of water-light needle last?

1, the principle of water injection needle

Water-light injection is to inject hyaluronic acid directly into the skin, which can make the facial skin moist, soft and shiny, make you have artist-like smooth and shiny skin, solve the problem of insufficient moisture in the dermis, improve fine wrinkles and bring obvious effects.

Through injection, it can solve facial problems, quickly decompose melanin and yellow pigment in human skin, repair damaged cells, supplement activated whitening factor, update cells of whole body whitening factor, make whole body skin turn red from inside to outside, and restore elasticity. Its characteristics are that it can quickly reverse the premature aging of pathological functional cells, inhibit cell oxidation, prevent melanin production, promote metabolism, effectively weaken and remove pigmentation, regulate skin from the inside out, and achieve the effect of whitening the whole body.

2, the role of water needle

(1) Effectively improve wrinkles on face, neck and hands (less irritation to sensitive parts such as crow's feet and decree lines).

(2) Whitening and tender skin, improving dull complexion.

(3) Shrink pores, increase elasticity and tighten skin.

(4) Fully replenish water to make skin moist, tender, shiny and more youthful and transparent.

(5) Fade spots and improve acne.

3. How long does the water needle effect last?

After water is injected into dermis, it will hydrate with cells, promote blood microcirculation and skin's absorption of nutrients, and be continuously diluted and absorbed. So the duration of water injection is limited.

Generally speaking, people with dry skin and neglect of maintenance can maintain it for a short time, about 3 months. The time of water injection maintenance is related to the number of injections. The maintenance time after the first injection is short, about 1-2 months. After three consecutive water light injections, the effect can be maintained at about 1 year, but the maintenance time will be different according to personal physique, skin quality and living habits.

4. Factors affecting the effect of water-light needle

(1) skin repair ability after stimulation

When the water-light needle is injected, the needle will stimulate and damage the epidermis, destroy the self-protection barrier of the skin, and cause slight traumatic inflammation. This requires the skin to repair itself quickly and perfectly, otherwise it may have no cosmetic effect or even lose its ability.

In addition, the water-light needle directly injects the beauty ingredients that are difficult to be absorbed by normal skin into the dermis, which is contrary to the normal physiology of the skin, and it is difficult to completely avoid the stimulation to the skin, especially when the ingredients are impure, complex, large and sensitive.

(2) Molecular size and structure of hyaluronic acid

Hyaluronic acid (hyaluronic acid) is a classic injection component of water needle, and its molecular size and structure are closely related to its functional characteristics. Hyaluronic acid used for micro-plastic surgery is a cross-linked macromolecular product, so that it can only have a certain volume after entering the skin, which is not easy to be rapidly decomposed and metabolized by the skin, and can support the parts that need to be enriched or corrected, so the injection position is usually deep rather than shallow.

However, water-light injection is to inject hyaluronic acid into dermis, which belongs to shallow injection. In order to avoid protruding on the skin surface after injection, cross-linked hyaluronic acid with large molecular weight should not be used. Some institutions even inject non-crosslinked small molecular hyaluronic acid for safety. Such hyaluronic acid quickly decomposes and fails after entering the skin, with quick results and quick failure, and often returns to its original shape within one month.

(3) Injecting beauty ingredients

Different cosmetic ingredients of Shuiguangzhen will have different cosmetic effects. In addition, the more ingredients injected, the better. After all, with the increase of ingredients, the risk of stimulation will increase accordingly. Commonly used ingredients are as follows:

Hyaluronic acid: rich in moisture, the skin becomes delicate, smooth, moist and white due to sufficient moisture;

Botulinum toxin: fine pores, smooth skin, reduce oil secretion;

Glutathione: whitening, anti-oxidation, synergistic with vitamin C, is one of the main components of the classic whitening needle.

L- vitamin C: whitening, anti-oxidation and promoting collagen synthesis, which is one of the main components of the classic whitening needle.

(4) Metabolic speed of beauty ingredients

After these cosmetic ingredients enter the skin, they will gradually decompose and fail. The faster the catabolism, the shorter the duration of the effect. This process varies greatly from individual to individual, which is also the reason why the maintenance time of Shuiguangzhen is very different.

In addition, because the injection is shallow, only small and medium molecular components that are easy to disperse and decompose need to be injected, which determines that the maintenance time of water needles is mostly within 3 months.

Obviously, the water-light needle is really not zero-risk, but it is a good way to beautify the skin first aid, especially suitable for people who have recently attended important occasions (such as marriage) and need to get flawless skin quickly.
