Choosing the right LED light can make your skincare routine easier and more targeted. Different wavelengths are commonly used for different cosmetic skin goals, from improving the look of dullness and fine lines to supporting clearer-looking skin.

This guide explains what each light is generally used for and how to choose the best setting for your routine.

Red Light

Red light is one of the most popular LED settings for skin rejuvenation.

It is commonly used in routines focused on improving the appearance of fine lines, uneven texture, dullness and loss of firmness. Red light is often chosen by people looking for a smoother, fresher and more radiant-looking complexion.

Choose red light if your goal is: smoother-looking skin, improved radiance, visible anti-ageing support or a firmer-looking complexion.

Blue Light

Blue light is commonly used for blemish-prone or oily-looking skin.

It is often included in LED skincare routines designed to support a clearer-looking complexion and improve the appearance of visible breakouts.

Choose blue light if your goal is: clearer-looking skin, support for blemish-prone areas or improving the appearance of oily and congested skin.

Purple Light

Purple light typically combines red and blue wavelengths, allowing you to target more than one cosmetic skin concern in the same routine.

It can be a useful option when your skin appears blemish-prone but you also want to support overall skin rejuvenation.

Choose purple light if your goal is: combined blemish support and skin rejuvenation.

Near-Infrared Light

Near-infrared light is invisible to the human eye and is generally used alongside visible red light in more advanced LED skincare devices.

Because it can reach deeper than visible red light, it is commonly included in routines focused on the appearance of firmness, texture and overall skin vitality.

Choose near-infrared if your goal is: deeper skin-supporting light therapy, firmer-looking skin and advanced rejuvenation.

Which Light Should I Choose?

A simple way to choose your setting is:

• Fine lines, dullness or loss of firmness → Red Light
• Blemish-prone or oily-looking skin → Blue Light
• Multiple concerns → Purple Light
• Advanced rejuvenation → Near-Infrared Light

Your skin needs can change, so you do not have to use the same setting every time.

How Often Should You Use LED Light Therapy?

Consistency is generally more important than longer treatment sessions.

Follow the treatment time and usage frequency stated in your device instructions. Do not assume that using the mask for longer will produce better results.

Depending on the device, LED skincare may be used several times per week as part of a regular routine.

Your LED Skincare Routine

For most routines, start with freshly cleansed and dry skin.

Use your LED mask before applying heavy creams or products unless your device instructions state otherwise.

After your LED session, you can continue with your usual skincare routine, such as serum, moisturiser and other suitable products.

During the daytime, finish your skincare routine with sunscreen.

Can I Alternate Between Different Lights?

Yes, depending on your device instructions and skincare goals.

For example, someone focusing mainly on signs of ageing may use red light more frequently, while someone experiencing visible blemishes may choose blue light.

You can adjust your routine as your skin needs change.

However, always follow the recommended usage instructions for your specific LED device.

When Should I Expect Results?

LED skincare works best as part of a consistent routine rather than as a one-time treatment.

Some users may notice their complexion looking refreshed relatively quickly, while changes in the appearance of texture, firmness or blemishes can take longer.

Results vary between individuals depending on factors such as skin type, lifestyle, skincare routine and consistency.

Tips for Getting the Most From Your LED Routine

Use the device on clean skin, keep your routine consistent, follow the recommended treatment duration and avoid exceeding the manufacturer’s instructions.

Pairing LED therapy with a simple, well-balanced skincare routine can help you maintain healthier-looking skin over time.

Important Safety Information

LED skincare devices should always be used according to their supplied instructions.

If you have a condition that causes sensitivity to light, an eye condition, or take medication that may increase photosensitivity, consult an appropriate healthcare professional before using an LED device.

Do not stare directly into bright LEDs unless your device has been designed and tested for use around the eyes according to its instructions.
