Question 1

What is Blue Light Therapy

Accepted Answer

Blue light sessions use a specific range of ultraviolet light (typically around 311–313 nanometres) delivered in short, controlled exposures within a dedicated light unit.
This wavelength range is often referred to as Narrowband UVB (NB-UVB). It represents a narrow part of the wider UV spectrum and is commonly discussed in both clinical and non-clinical settings.

At Battersea Park Clinic, NB-UVB sessions are offered as part of our skin-focused wellbeing services. Sessions are designed to provide a controlled, structured light exposure experience in a calm environment. They are not described or promoted as medical treatment, and no claims are made about diagnosing, treating, or preventing health conditions.

Many people choose to explore NB-UVB sessions out of interest in light-based wellbeing technologies, skincare routines, or structured self-care experiences. Individual experiences vary.

If you have a skin condition, are under medical care, or have questions about suitability, we strongly encourage you to speak with a qualified healthcare professional before booking.

Question 2

How does it work?

Accepted Answer

NB-UVB sessions involve short, controlled exposure to a narrow range of ultraviolet light (around 311–313 nm) using a dedicated light unit.
This wavelength range is often discussed in research and specialist settings in relation to skin and light-based technologies. However, at Battersea Park Clinic, NB-UVB sessions are offered as a skin-focused wellbeing experience only.
People choose to explore NB-UVB sessions for a range of personal reasons, including:

• Interest in light-based skincare technologies
 • Curiosity about services commonly used in specialist environments
 • Preference for guided use of professional equipment rather than home devices
 • Desire for structured, short sessions as part of a self-care routine

Individual experiences vary, and no claims are made about the diagnosis, treatment, or prevention of medical conditions.

If you have an existing skin condition, are under medical care, or have concerns about suitability, we encourage you to speak with a qualified healthcare professional before booking.

Question 3

What conditions or concerns is it commonly used for?

Accepted Answer

NB-UVB light is widely referenced in clinical and academic settings in relation to a range of skin conditions. However, at Battersea Park Clinic, NB-UVB sessions are offered strictly as a skin-focused wellbeing experience, and are not described or promoted as medical treatment.

People choose to explore NB-UVB sessions for many personal reasons, including:

• Interest in light-based skincare technologies
 • Desire for guided use of specialist equipment rather than home devices
 • Curiosity about services commonly discussed in dermatology settings
 • Preference for short, structured sessions as part of a self-care routine

If you have a diagnosed skin condition, ongoing symptoms, or concerns about your health, it is essential to seek advice from a qualified healthcare professional or dermatologist before booking.

Question 4

Sessions & Safety Information

Accepted Answer

NB-UVB sessions are short, structured and guided by our team to ensure they are delivered in a careful and consistent way.

• Sessions are typically booked 2–3 times per week, depending on personal preference
 • Individual sessions last only a few minutes, with exposure times explained clearly before you begin
 • Eyes and sensitive areas are always protected during sessions
 • Male clients are asked to wear protective covering during sessions
 • Some medications can increase sensitivity to light, so we ask clients to review their medication use and seek advice from a healthcare professional if unsure

These measures are in place to support comfort and safe use of the equipment.

NB-UVB sessions at Battersea Park Clinic are offered as a wellbeing and skincare-focused experience and are not described or promoted as medical treatment.

Question 5

How many sessions will I need?

Accepted Answer

There is no fixed number of sessions that suits everyone. How often people choose to book sessions varies based on personal preference and how they wish to include them within their wider self-care routine.

Some people prefer to try a small number of sessions first, while others choose to book sessions more regularly over a period of time.

Our team are happy to explain how sessions work and outline the different booking options available, so you can decide what feels right for you. Sessions are offered as a wellbeing experience and are not described or promoted as medical treatment.

Question 6

Can blue light sessions be used alongside other services?

Accepted Answer

Yes. Some clients choose to book blue light sessions alongside other wellbeing services such as red light sessions, skincare routines, or broader lifestyle practices.

Our team can explain what each service involves and how people commonly choose to combine sessions, so you can decide what feels appropriate for you. We do not provide medical advice or recommend treatments for health conditions.

If you have a medical condition or are unsure about suitability, we recommend speaking with a qualified healthcare professional before combining services.

Question 7

Are there side effects?

Accepted Answer

Most people find NB-UVB sessions comfortable and well tolerated. As with any form of light exposure, some temporary effects can occur.

Possible short-term effects may include:

• Mild redness or dryness of the skin
 • Temporary sensitivity to light
 • Mild eye discomfort if eye protection is not used correctly
 • Occasional itchiness or warmth in treated areas

These effects are usually mild and settle on their own. Following the guidance provided before and after your session can help reduce the chance of discomfort.

Longer-term considerations:
Frequent or prolonged exposure to UV light of any kind is commonly discussed in relation to skin ageing and skin health. For this reason, exposure times are kept short and structured, and clients are encouraged to consider their overall skin health and history when deciding whether sessions feel appropriate for them.

If you have a history of skin cancer, are under dermatology care, or have concerns about skin sensitivity, you should speak with a qualified healthcare professional before booking.

Question 8

Who should avoid blue light therapy?

Accepted Answer

NB-UVB sessions involve exposure to ultraviolet light. For this reason, some people should seek advice from a qualified healthcare professional before considering whether sessions are appropriate for them.

This may include people who:

• Have a history of skin cancer (including melanoma or multiple non-melanoma skin cancers)
 • Have autoimmune conditions that are affected by light exposure (such as lupus)
 • Experience strong sensitivity to sunlight or develop rashes after sun exposure
 • Take medications that increase sensitivity to light
 • Have existing eye conditions that affect light tolerance
 • Are pregnant
 • Have other complex medical histories or concerns about light exposure

This list is not exhaustive. If you are unsure, the safest approach is always to speak with your GP, dermatologist, or another qualified healthcare professional before booking.

Battersea Park Clinic does not assess medical suitability, diagnose conditions, or provide medical clearance.

Important general guidance

Because NB-UVB involves UV light exposure, it is generally sensible for anyone using light-based services to:

• Avoid additional intentional UV exposure (such as sunbeds or excessive sunbathing)
 • Use appropriate sun protection in daily life
 • Be mindful of their own skin history and sensitivities

If you are under the care of a dermatologist, it is best to discuss any light-based services with them before booking.
