Changguang Huaxin 808nm VCSEL Laser Hair Removal Chip | The New Generation Laser Hair Removal Device Revolutionary

In recent years, with the rise of the "appearance economy," consumer electronics have gained a new core. Some "home beauty" technologies that can ignite new lifestyles have quietly become favorites among beauty enthusiasts. The popularity of home-use hair removal devices offers consumers a safer, more effective, convenient, and fast new way to remove hair at home, becoming a new market highlight.

According to data from the "Online Home Beauty Device Consumer Insight Report," the market size of hair removal devices in China is expected to approach 10 billion yuan. During last year's 618 shopping festival, hair removal devices topped the retail sales of beauty devices on both Tmall and JD.com. Tmall's annual sales data alone shows that the total sales of hair removal devices reached 4.151 billion yuan.

In the past 30 days, on Alibaba's platform, user search data for hair removal devices shows that "home use" and "laser" are popular search demands for hair removal devices.

Currently, the mainstream hair removal methods in the market are IPL hair removal and laser hair removal, but laser hair removal has obvious advantages.

Comparison of mainstream hair removal methods in the market

Both laser hair removal and IPL hair removal work on the principle of selective light absorption, using a certain light source to penetrate the epidermis so that the melanin in the hair shaft absorbs the most photon energy. The heat from the hair shaft quickly transfers to the hair follicle, raising its temperature rapidly to 50-60 degrees Celsius, thereby destroying the hair follicle tissue and preventing hair growth. However, laser hair removal causes less pain and is safer, faster, and longer-lasting, making it more favored by consumers.

808nm Wavelength, the "gold standard" light source for laser hair removal

Human skin is generally divided into six types: Type I and II for fair skin, Type III and IV for yellow skin, and Type V and VI for brown to black skin.

From the perspective of safety and avoiding side effects, when the skin color type is (I to IV), a wider range of options is available. Using 808nm semiconductor laser and 755nm alexandrite laser are both effective, but the 755nm wavelength is shorter and causes more skin damage. When the skin color type is (IV to VI), the 1064nm Nd:YAG laser is the safest choice, but it is not very safe for lighter skin. Considering that the market demand is greatest for fair and yellow skin, the 808nm wavelength is regarded as the gold standard for laser hair removal.

808nm The working principle of semiconductor laser hair removal devices is the same as IPL hair removal devices, but IPL actually belongs to high-pressure gas discharge lamps, commonly understood as a flash lamp, with a spectral range of 500-1200nm. Therefore, a large amount of useless spectral heat is absorbed by the epidermis, resulting in low hair removal efficiency, stronger pain than laser hair removal, and longer hair removal time.

● Good ● Medium ● Bad

In summary, a safe and stable wavelength, lightweight and portable appearance, comfortable light-sensing experience, and cost-effective home-use 808nm semiconductor laser hair removal device are the new favorites in the consumer market.

808nm VCSEL , the revolutionary new generation handheld laser hair removal device

In recent years, the explosion of VCSEL application scenarios has brought the best development opportunity for laser chips. With the maturity of 808nm VCSEL laser chip technology, its stable wavelength, low divergence circular beam, high efficiency, no need for water cooling, and low cost perfectly match the trend of hair removal products toward commercialization, home use, and lightweight design. It is leading the revolution of the new generation of home handheld laser hair removal devices and has become one of the new favorites in the home consumer electronics field.

VCSEL is a vertical-cavity surface-emitting laser, which differs greatly in structure from traditional edge-emitting lasers (EEL). This difference effectively compensates for the application drawbacks of traditional laser hair removal and offers unique advantages:

● Stable wavelength, low temperature drift coefficient, no need for water cooling;

● Emission perpendicular to the substrate, easy optical shaping, simple optical path;

● Uniform beam energy, no local high power causing epidermal burns;

● Very small active region size, enabling high packaging density and low threshold current, suitable for handheld devices;

● Wafer-based manufacturing process, low cost (traditional EEL requires cleavage, coating, packaging, and other processes).
