Description

TECHNICAL AREA

[0001] The present utility model relates to the field of beauty devices, in particular a laser hair removal device. STATE OF THE ART

[0002] In the personal care and beauty sector, consumer demand for more precise and convenient skincare is continuously increasing. Hair removal, as a fundamental beauty treatment, is experiencing steadily growing market demand. Currently available hair removal methods are primarily based on temporary techniques. Due to their ease of use and availability, they are widely applied in various scenarios, such as daily home care and emergency hair removal on the go, making them the entry-level option for most users.

[0003] While shaving is currently easy and inexpensive, it only removes the hair on the skin's surface. The hair grows back quickly, and repeated shaving can lead to thicker hairs, skin irritation, or ingrown hairs. Chemical depilatory products, such as creams or foams, dissolve the hair using chemicals, but the effect is only temporary and can cause skin allergies and redness; they are also less suitable for sensitive skin. Physical methods, such as waxing or plucking, can extend the hair removal cycle, but they cause significant pain during application and can damage hair follicles, leading to inflammation or pigmentation.
