How to get rid of freckles

Causes of spots

The scary thing about a stain is that it spreads and spreads, and very quickly. Maybe there are only a few spots on the face now, but a large lump of melanin may have accumulated in the lower layer of the skin, which will burst out on the surface at a certain time.

Common causes of discoloration include UV factors; endocrine disorders;
Excessive stress factors will lead to the destruction of the metabolic balance, the slow supply of nutrients required by the skin, and the pigment mother cells will become active;

Improper use of cosmetics can easily lead to allergies. If excessive ultraviolet rays are irradiated during the treatment, the skin will accumulate melanin in the inflammatory area in order to resist the damage;
Improper living habits can cause skin sensitivity. In order to protect the skin, the body will secrete a lot of pigments to protect the skin.

Classification of spots
For the classification of pigmentation, it can be roughly divided into two categories according to the skin layer: epidermis and dermis.
Epidermal spots: freckles, sunburn, age spots, etc.; dermal spots: Ota nevus, coffee spot, brown blue nevus, chloasma, etc.;

Pigmentation Treatment
Photorejuvenation
Photon skin rejuvenation is essentially intense pulsed light (Intense Pulsed Light, IPL), and its effect is more on the overall brightening. For relatively obvious pigmentation, including some spots, the effect will be relatively slight.
As can be seen from the figure above, unlike lasers, which are often fixed in a small range of wavelengths, IPL covers a very long band of light in the range of 400-1400nm, including visible light and invisible parts.
Applying selective photothermolysis, IPL can make different molecules in the skin selectively absorb light of corresponding wavelengths, thereby achieving therapeutic effects.
The reason for brightening skin tone is also because melanin absorbs more light of a certain wavelength, and will decompose after reaching a certain amount of heat, thereby helping to improve dull skin tone.

Shuiguang Needle
The principle of water light needle is different from photon skin rejuvenation and various lasers. Water light needle can skip the stratum corneum and directly inject these functional ingredients into the deeper layer of the skin. Add some whitening ingredients, such as VC, nicotinamide, etc., to the water light needle, because the loss of transdermal is reduced, and the efficiency of these functional ingredients is higher.
Therefore, the water light needle can also play a role in whitening and lightening spots, which is closer to skin care in principle.
