Understanding different skin types is key to delivering an effective and safe treatment and diagnosis to a client. The skin type of a new client should always be one of the first considerations when looking at the next steps of their treatment – this goes for all laser treatment procedures including, laser hair removal, laser tattoo removal, and vascular lesion treatment.
Different skin types will all react differently toward exposure to a laser. Without the correct match of treatment to skin type you will not only fail to deliver effective treatment, but also risk damaging the treated skin area. It is important to make sure all of the practitioners in your laser clinic understand how to treat skin types correctly.
Why Does Treatment Effectiveness Vary with Skin Type?
The type of skin your client has is one of the largest factors to consider when assessing the treatment you will give. The general rule when it comes to skin type is the lighter the skin complexion the more effective treatment and the less side effects there will be. Older laser treatments have been known to cause discolouration and damage to dark skin types, however advancements in laser treatment have reduced this.
Darker skin types contain higher amounts of melanin. This acts as a chromophore which absorbs the energy from the laser – the more melanin, the higher the absorption. As more energy is absorbed there is a higher risk of injury to the treated area. Considerations should also be made to whether the skin of your client scares easily. Skin which is more prone to scarring is more likely to be adversely affected by laser treatment.
The Fitzpatrick Scale
The Fitzpatrick Scale is a numerical classification system that assigns a specific skin type to individuals based on their genetic predisposition and response to UV radiation. It helps professionals, such as dermatologists and aestheticians, assess skin types for various purposes, including determining appropriate treatments, developing tailored skincare regimens, and predicting the risk of certain skin conditions.
Laser hair removal is most successful when there is a large contrast between the skin and hair (dark hair on light skin being the optimum combination). For darker skin complexions devices such as the Helios III are ideal thanks to its Nd: YAG laser.

Below are the six skin classifications on the Fitzpatrick scale, and how you can help identify each skin type.
Below are the six skin classifications on the Fitzpatrick scale, and how you can help identify each skin type.
Skin Type I
People with Type I skin have very fair complexions. They often have light-coloured or red hair, light-coloured eyes, and a large number of freckles. Type I skin is highly sensitive to the sun and tends to burn easily, with minimal or no tanning ability. Individuals with Type I skin are at the highest risk of developing skin cancer due to their low melanin production and minimal natural protection against UV radiation. Sun protection measures, such as seeking shade, wearing protective clothing, and using a broad-spectrum sunscreen, are essential for Type I individuals to prevent sunburn and reduce the risk of skin cancers.
Skin Type 2
Type II skin is characterised by fair complexions, typically seen in individuals with light-coloured hair and eyes. While Type II individuals also have a higher risk of sunburn, their skin has a slightly better ability to tan compared to Type I skin. However, tanning is minimal and requires cautious exposure to the sun. Similar to Type I, individuals with Type II skin need to be vigilant about sun protection and adopt preventive measures against sun damage and skin cancer.
Skin Type III
Type III skin encompasses a range of light to medium skin tones. Individuals with Type III skin can have a mix of eye and hair colours. They tend to have a moderate risk of sunburn initially but can develop a tan with continued exposure to the sun. Although Type III skin has more natural protection against UV radiation due to increased melanin production, it is still important for individuals with this skin type to practice sun safety and wear sunscreen regularly to minimise the risk of sunburn and long-term sun damage.
Skin Type IV
Type IV skin is characterised by an olive to moderate brown complexion, often seen in individuals with Mediterranean, Hispanic, or South Asian backgrounds. People with Type IV skin rarely experience sunburn and can tan easily. They have a moderate risk of developing skin cancer compared to lighter skin types but should still take precautionary measures to protect their skin from the harmful effects of the sun. While Type IV skin provides some natural defence against UV radiation, sunscreen and other sun-protective methods should still be utilised.
Skin Type V
Type V skin is characterised by dark brown complexions, commonly found in individuals with African, Afro-Caribbean, or Southeast Asian heritage. People with Type V skin rarely experience sunburn and tan easily. Due to the higher melanin content, Type V skin has a lower risk of developing skin cancer compared to lighter skin types. However, this does not mean that sun protection is unnecessary. Sunscreen, protective clothing, and seeking shade should still be practised to maintain overall skin health and minimise any potential risks.
Skin type VI
Type VI skin is the darkest skin type, typically seen in individuals with African or African-American heritage. People with Type VI skin rarely experience sunburn and have a high natural resistance to UV damage due to abundant melanin production. However, it is important to note that even with this natural protection, individuals with Type VI skin are not entirely immune to sun damage or the risk of skin cancer. Regular skin examinations, self-checks, and preventive measures such as sun protection should still be followed to maintain optimal skin health.
Laser Hair Removal and Fitzpatrick Skin Types
As the owner of a laser clinic, it is essential to understand the relationship between laser hair removal and Fitzpatrick skin types. Laser hair removal is a popular and effective method for achieving long-lasting hair reduction, but it requires careful consideration and tailored approaches based on the client’s skin type. By understanding the Fitzpatrick Scale and its implications, we can provide safe and effective laser hair removal treatments for clients with various skin tones.
Considerations for Laser Hair Removal Based on Skin Types
When it comes to laser hair removal, different Fitzpatrick skin types require different considerations. The amount of melanin in the skin plays a crucial role in determining the appropriate laser settings and treatment approach. Here are a few key considerations for each Fitzpatrick skin type:
Type I and II: Very fair and fair skin
Clients with Type I and II skin have low melanin content and are at a higher risk of adverse reactions, such as burns or hyperpigmentation, during laser hair removal. Extra caution is necessary to ensure the laser settings are adjusted accordingly, taking into account the reduced melanin absorption. Longer pulse durations and lower energy levels may be used to minimise the risk of complications.
Type III and IV: Light to moderate brown skin
Type III and IV skin tones have a moderate amount of melanin, making laser hair removal generally safe and effective. However, it is still crucial to choose appropriate laser wavelengths and settings to target the hair follicles while minimizing the risk of damaging the surrounding skin. Nd:YAG lasers are often a preferred choice for these skin types due to their ability to bypass the higher melanin concentration in the skin and focus on the hair follicles.
Type V and VI: Dark brown and very dark skin
Clients with Type V and VI skin have higher melanin content, which poses certain challenges for laser hair removal. The risk of adverse reactions, such as burns or hypopigmentation, is increased in these skin types. Choosing the right laser system, such as Nd:YAG lasers with longer wavelengths, allows for safer treatment by selectively targeting the hair follicles while minimising damage to the surrounding skin. Conducting test spots and ensuring proper cooling during treatment can help mitigate potential risks.
By carefully considering the Fitzpatrick skin types and selecting the appropriate laser technology, laser clinic owners can provide safe and effective laser hair removal treatments for clients with various skin tones, ensuring optimal results while minimising the risk of complications.
Before starting any treatment be sure to consult the Fitzpatrick scale and assess the skin type of your client. While providing treatment always be aware of the skin type you are treating, and the characteristics it has – this will help provide a more effective treatment to your client and reduce any adverse effects of laser treatment. Here at Laseraid we offer full training on all of our equipment to ensure both you are your client have the best possible experience with laser treatment.
