If you are tired of constant shaving or painful waxing sessions, you have likely considered laser hair removal as a longer-term solution. But with so many different laser technologies available, choosing the right one for your skin type can be confusing. In this article, we will break down the various types of lasers commonly used in aesthetic centres and clinics, and we will offer you some practical advice on how to select the best laser for your skin.
Laser hair removal works by targeting the pigment (melanin) in hair follicles, effectively destroying them to prevent future growth. Different lasers are designed to work on various skin tones and hair colours, so understanding your skin and hair type is essential for achieving the best results.
So, let us now explore the most commonly used lasers in hair removal and their suitability for the different skin types.

Alexandrite Laser: Ideal for Fair Skin
The Alexandrite laser is one of the most popular types used for laser hair removal, especially for individuals with fair skin (types I-III on the Fitzpatrick scale). It operates at a wavelength of 755 nm, which allows it to penetrate the skin efficiently and target melanin in light-coloured hair.
Benefits
- Quick and effective: Alexandrite lasers cover large areas of skin in a short time, making them suitable for areas like the back, chest, or legs.
- Suitable for lighter skin tones: Due to its shorter wavelength, it works best on individuals with fair skin and dark hair.
Drawbacks
- Not recommended for darker skin tones: The high melanin content in darker skin may absorb the laser energy, leading to burns or hyperpigmentation.
- Limited effectiveness on light or fine hair: Alexandrite lasers are not the best choice for those with blonde, gray, or red hair.
Diode Laser: Versatile for Light to Medium Skin Tones
The Diode laser is widely regarded as one of the most versatile options for hair removal, particularly for individuals with light to medium skin tones (types I-IV). It operates at a wavelength of 800 – 810 nm, allowing it to penetrate deeper into the hair follicle.
Benefits
- Effective on thicker hair: The Diode laser works exceptionally well for targeting coarse, dark hair on both men and women.
- Safe for a wider range of skin types: Compared to Alexandrite, the Diode laser can be safely used on slightly darker skin tones without risking significant skin damage.
Drawbacks
- Less effective on very dark skin tones: While it is more flexible than Alexandrite, individuals with very dark skin (types V-VI) may still experience side effects such as hyperpigmentation.
- May require more sessions: The Diode laser can sometimes take more treatments to achieve complete hair removal compared to other laser types.
Nd Laser: Best for Darker Skin
For individuals with darker skin tones (types V-VI), the Nd laser is often the safest and most effective choice. It operates at a wavelength of 1064 nm, the longest of any laser used in hair removal. This allows it to bypass the melanin in the skin and directly target the hair follicles, making it ideal for people with dark skin.
Benefits
- Safe for all skin types: Its long wavelength makes the Nd laser a safe option for even the darkest skin tones.
- Effective for larger body areas: The Nd laser is commonly used for treating areas like the legs and back.
Drawbacks
- Less effective on fine or light hair: Due to its lower absorption by melanin, it may not work as well on lighter hair or fine hair strands.
- More discomfort: Nd lasers can be more uncomfortable during treatment compared to others, and post-treatment recovery may involve mild swelling or redness.
Ruby Laser: Best for Light Skin and Fine Hair
The Ruby laser, one of the earliest lasers used for hair removal, operates at a wavelength of 694 nm. It is best suited for individuals with very fair skin and fine, light-coloured hair. Although it is less commonly used today, it can still be a good choice for specific cases.
Benefits
- Effective on fine hair: Ruby lasers are known for targeting lighter, finer hairs that other lasers may struggle to remove.
- Low risk of side effects for light skin: Due to its high melanin absorption, Ruby is very safe for those with fair skin.
Drawbacks
- Not suitable for dark or medium skin tones: The Ruby laser’s wavelength makes it inappropriate for use on darker skin, as the risk of burns or pigmentation issues is high.
- Slower treatment process: The Ruby laser covers smaller areas, so sessions may take longer, especially for large body areas like the back or legs.
How to Choose the Best Laser for Your Skin
Choosing the right laser for your skin type involves considering factors like your skin tone, hair type, and the area being treated. Here is how to make the best decision for your specific needs:
- Know Your Skin Type
Your skin type is a critical factor when determining the best laser for you. Lighter skin tones (types I-III) typically respond well to lasers like Alexandrite and Diode, while darker skin tones (types IV-VI) are better suited for Nd lasers.
- Hair Colour and Thickness
Lasers like the Diode and Alexandrite work best on thick, dark hair, while Ruby lasers are a good choice for individuals with lighter, finer hair. If you have blonde or gray hair, laser treatments may be less effective since these hair types contain less melanin.
- Treatment Area
Consider the size of the area you want to treat. Alexandrite and Nd lasers are ideal for covering larger areas like the legs, chest, or back, while smaller areas (like the face or underarms) may benefit from Ruby or Diode lasers.
- Consult a Professional
It is always best to consult with a licensed laser specialist or dermatologist before starting any hair removal treatment. They can evaluate your skin and hair type to recommend the safest and most effective laser technology for your needs.
Which Laser is Best for Your Skin?
Each laser type has its own advantages, and the best option for you depends on your skin tone, hair colour, and treatment goals. For those with fair skin, the Alexandrite and Ruby lasers are excellent choices, while the Diode lasers offer versatility for light to medium skin tones. If you have darker skin, the Nd laser is the safest and most effective solution.
By choosing the right laser and following the recommendations of a qualified specialist, you can enjoy smooth, hair-free skin without the hassle of constant shaving or waxing. Laser hair removal is not only an investment in convenience but also in long-term skin health and confidence.
