How does laser achieve permanent hair removal?

During laser hair removal, the laser transforms into heat, penetrating your hair follicle to reach the hair bulb. It disrupts blood vessels and the hair growth environment, where the laser exerts its effects. Laser is most effective during the anagen phase of hair growth, explaining the gradual process of permanent hair removal.

Can DermRays Laser manage PCOS hair growth?

Absolutely. The precision and high energy density of the DermRays Laser effectively target hair follicles at the root, providing hair removal treatment and reducing ingrown hairs.

What is the difference between 810nm Laser and 1064nm Laser?

The main difference between 810nm and 1064nm laser hair removal lies in their wavelength and target area.


· 810nm Laser Hair Removal: This wavelength is highly absorbed by melanin, the pigment in hair follicles. It is most effective for lighter skin tones and lighter hair colors. The 810nm wavelength targets the hair follicle directly, heating it and effectively disabling hair growth.


· 1064nm Laser Hair Removal: This wavelength has a longer penetration depth and is less absorbed by melanin. It is suitable for all skin types, including darker skin tones, and can effectively treat deeper hair follicles. The 1064nm wavelength primarily targets the blood supply to the hair follicle, making it a versatile option for a wide range of skin and hair types.


In summary, while 810nm laser hair removal is more targeted towards lighter skin tones and lighter hair colors, 1064nm laser hair removal is suitable for all skin types and can penetrate deeper into the skin to treat a broader range of hair follicles.

What are the differences between Laser and IPL?

Laser hair removal is based on the principle of selective photothermal effect, utilizing a focused laser beam with a single wavelength. This focused beam can penetrate deep into the hair follicles, where it is specifically absorbed by melanin to generate heat, causing damage to the follicles and preventing hair growth.


Similarly based on photothermal effect, IPL hair removal uses broad-spectrum light with multiple wavelengths. Unlike laser, IPL light is not focused but can be absorbed by melanin on the skin surface and in the hair follicles, causing thermal damage and preventing hair growth.


Key Differences:
A) Light Source:
Laser: Single-wavelength focused beam.
IPL: Broad-spectrum light with multiple wavelengths, unfocused.
B) Pain During Use:
Laser: Mainly absorbed by melanin, resulting in less pain.
IPL: Broad-spectrum light absorbed by multiple tissues, causing a stronger burning sensation.
C) Treatment Effect and Duration:
Laser: Typically requires fewer treatments with relatively evident and long-lasting results.
IPL: Generally requires more treatments with shorter-lasting effects, despite similar energy intensity to laser.

What are the differences among diode laser, YAG laser, and alexandrite laser?

Each type of laser has unique characteristics that make it suitable for specific hair removal scenarios:


· Diode lasers are often preferred for their precision and effectiveness. They are commonly used in professional settings and at-home devices for targeting hair follicles with minimal discomfort. Diode lasers are known for their relatively fast treatment times and are suitable for various body areas.


· YAG lasers are commonly used in medical settings and are ideal for treating larger body areas.


· Alexandrite lasers are commonly used in professional settings, especially for smaller body areas like the face, underarms, and bikini line.

What are the differences among the common wavelengths used in laser hair removal: 810nm, 808nm, and 755nm?

The differences between these wavelengths primarily lie in their absorption properties, effectiveness, and target areas:


· 810nm Laser: The 810nm wavelength is highly absorbed by melanin, the pigment in hair follicles. This makes it effective for targeting hair follicles, particularly in lighter skin tones. 810nm lasers are known for their precision and efficacy in hair removal, especially on finer hair.


· 808nm Laser: Similar to the 810nm wavelength, the 808nm wavelength is also highly absorbed by melanin.


· 755nm Laser: The 755nm is highly effective for hair removal on lighter skin tones and can also target finer hair. 755nm lasers are known for their speed and efficiency in reducing hair growth.


In summary, while all three wavelengths target melanin in the hair follicle. The choice of wavelength depends on factors such as skin type, hair color, and treatment goals.
