Hydrocool-4H Laser system has four treatment handles at the same time, including 808 freezing point hair removal handle, DPL handle, YAG eyebrow washing, tattoo washing handle, RF anti-wrinkle anti-aging handle. One machine is multi-functional and has most of the functional requirements in the market.

The princples of Hydrocool_4H                                          

808 hair removal handle:

The wavelength of the diode laser with 808 nm is optimal for the energy transfer, to the endogenous dye melanin in the hair suitable. This dye converts the light into heat. During treatment with the diode laser, the handpiece sends controlled light pulses above the desired location. There, the light is absorbed by the melanin, in the hair root.Due to the absorbed light the temperature in the hair follicle is raised and the proteins denature. After a destruction of the proteins no nutrients can get into the hair root anymore, which leads the hair to falling out. Without the supply of nutrients, no further hair can regrow.During a treatment with the diode laser 808, the heat can only penetrate the skin layer containing hair papillae. Due to the constant wavelength of the laser, the other skin layers are unaffected. Likewise, surrounding tissue and blood is not affected. Because the dye hemoglobin contained in the blood reacts only to a different wavelength.

DPL handle:

Intense pulsed light technology – also known as intense pulsed light technology, it can emit a set of special wavelengths of light , which can be absorbed by melanin and hemoglobin, thereby breaking these diseased tissues. IPLs work by emitting light at scattered wavelengths, and various cutoff filters are often used to selectively filter out unwanted wavelengths to target specific structural problems. This may be melanin in the form of pigmented lesions on the skin or oxyhemoglobin in blood vessels which manifests as capillaries rupture. Compared to laser hair removal, laser uses single-spectral light, while IPL uses multi-spectral light, which means that IPL energy is dispersed and much weaker. That said, IPL has more unfocused energy around the hair and skin area. Although DPL technology can remove hair, but for 4H laser, it already has 808 hair removal handle, therefore, we recommend DPL handle to solve facial pigmentation, telangiectasia, pores and other problems, by repairing various skin problems to achieve a fairer and more refined skin.

Nd:YAG Handle:

Nd:YAG laser is essentially a laser used to process pigments. Laser technology has greatly improved the ability to treat melanocytic lesions and tattoos with the rapidly pulsed Q-switch neodymium: yttrium aluminum garnet (Nd: YAG) laser. The laser treatment of pigmented lesions and tattoos is based on the principle of selected photothermolysis. The Nd:YAG handle in the 4H Laser has three tips to provide 532nm, 1064nm and 1320nm lasers, which can be selected for different patients’ skin conditions and tattoo colors. The QS Laser System can successfully reduce or eradicate a variety of benign epidermal and dermal pigmented lesions and tattoos while minimizing the risk of adverse effects.

Laser pigment removal machine though high energy of laser transient emission, make irradiated pigment particles absorb energy expansion rupture. Most or all of epidermal pigment group split into smaller tiny particles immediately ruled out in vitro. Part of dermal pigment group fragment into body macrophage phagocytic particles that ingest and excrete through the lymphatic system, thereby eliminating pigment. Due to normal tissue on 1064nm laser absorption is very few, maintaining the cell frame complete. No scar formation conditions. Because of the laser pigment removal is no damage to normal tissues, its security guaranteed maximum customer without complications from postoperative.Gradually the pigment becomes lighter and lighter till disappearing.

V-RF Handle:

RF (Radio Frequency) is to penetrate radio waves into the skin through frequency. These radio frequency currents will generate vibration and heat in the skin. This “resistance effect” will heat the real skin and shrink the collagen tissue, thereby making the skin firmer and bouncy. The working principle of radio frequency is to heat the deep layers of the skin, thereby destroying the molecular structure and causing tiny damage to the cells. Just as fitness is about destroying muscle cells and making them grow stronger and stronger. Radiofrequency destroys collagen and activates cells to produce more collagen. Cool the skin surface while heating the deeper layers of the skin.

In this way, a state of “cold outside and hot inside” is formed, which will produce two gratifying changes:

1) The dermis of the skin becomes thicker, and the wrinkles become lighter or disappear;

2) The shape of subcutaneous collagen is remodeled, and new collagen is produced to make the skin firmer.
