More and more women are seeing the light. When it comes to facials, that is. Light and laser treatments are becoming ever more popular. After first making waves in L.A., Liberty, Skin Laundry, a 15-minute express laser treatment center, opened its London outpost. Just across town is The Light Salon, which launched at Harvey Nichols' in 2015 and provides pop-in light facials.

Debbie Thomas, London’s go-to woman for lasers, opened D.Thomas Illuminate, which offers a menu of speed, laser-based, facials. This wave of high-tech treatment is the result of salons needing to keep up with the times. Specifically, global market insights company Mintel suggests that “[the] trend towards at-home devices, coupled with the rise in botox and fillers, has challenged the salon facial treatments market, and as a result, facials have become increasingly high-tech in a move to offer consumers something they cannot replicate at home.”

Of course, there are light and laser devices for at-home use, but in salons, the devices are more powerful and with an expert at the helm you’re set to see impressive results from a glowing complexion to a reduction in acne. But which treatment should you book? A light facial or a laser?

“Light and laser facials can actually complement each other very well,” says Debbie Thomas. “LED works more like a shining lamp triggering chemical reactions within the skin, whereas most lasers use heat to trigger more specific reactions within the skin. Lasers are more powerful so results will be quicker with fewer treatments however LED has very little risk associated with it.”

To help further understand the intricate differences between light and laser we called on Laura Ferguson, co-founder of The Light Salon and asked Debbie Thomas to shed more light on the subject.

Light Treatments

Having been for a few facials at The Light Salon, I can say that not only does sitting under a warm glow of light make you feel happier, (“lots of our clients call it the ‘happy light,’” Ferguson tells me) it also leaves you with an undeniable glow, making it ideal pre-party. And I’m not just imagining it, “clients will notice a lovely glow to the skin, which will last two to three days,” says Ferguson. “The treatment evokes the feeling of summer. The warmth travels into your body, warming you from inside, whilst the light mimics a dose of sunlight our bodies and minds crave. The combination of the warmth and movement of the light throughout the treatment lowers your stress hormones, boosts your feel-good hormones and boosts your immune system.”

LED is effectively a ‘first aid kit,’ healing wounds, reducing bruising and swelling and calming skin disorders (rosacea, psoriasis, eczema). It can be used to treat the most vulnerable and sensitive skin types and acts as an anti-inflammatory, whilst also strengthening the skin to help alleviate further symptoms,” explains Ferguson.

“It is hugely beneficial in supporting the aging process and forming a necessary structure for the skin. It emits specific therapeutic wavelengths of light (energy) into the skin that switches your system on to create healthy cells, renewing the lining of blood vessels and forming new blood vessels to improve skin’s appearance.”

But the LEDs used at The Light Salon are not your average bulbs. “Those found in household lighting or in televisions do not deliver the same wavelength, energy or intensity and therefore the body is unable to process the light in the same way."

“If the light is the correct wavelength, energy, and intensity, the cells in the dermis layer of skin will convert the delivered light (energy) into ATP (adenosine triphosphate), which is the fuel the cell uses to do its job. The increased energy in the cells leads to a boost in productivity, improving the production of collagen, elastin and hyaluronic acid,” says Ferguson.

Essentially LED light is incoherent light (light that is spread out) until it passes through a fluid (like the fluid in and around our skin cells) when it turns to a concentrated or “coherent” light, just like a laser.

Different LED Lights: What Do They Do?

Yellow Light is used for a minute to kick-start a treatment at The Light Salon. “It switches on the communication between cells, ensuring the dermal cells are ready for the delivery of the more powerful LED light to come,” says Ferguson.

Ferguson explains that Red LED therapy, which penetrates 8cm into the body, is used for the prevention and repair of aging skins because of its ability to stimulate collagen and elastin production. “It’s particularly beneficial for improving overall skin tone, reducing pigmentation and improving the potential of scarring.”

Near-infrared penetrates up to 15cm and can provide longer-lasting benefits, which is why this is the light used in The Light Salon facials after the minute of yellow light is administered. “It energizes and restores damaged and compromised cells and creates new cells, encouraging our bodies to produce collagen, elastin and hyaluronic acid more efficiently and effectively.

“It accelerates the healing process of wounds and can help improve the appearance of existing scars and prevent the formation of new scars. It can also reduce pain, bruising and inflammation post-laser treatment. It helps to stabilize abnormal conditions in the skin such as dermatitis, eczema, and psoriasis, increases blood flow and lymph drainage, speeds the removal of toxins, and delivers oxygen and nutrients to the skin, which benefits cell growth.

“Due to its longer wavelength, it can penetrate bone and muscle, and is therefore highly beneficial in improving the structure of the face, increasing bone density, strength, and thickness, particularly around the eye sockets, which naturally get larger with age, causing sunken eyes and sagging skin,” explains Ferguson.

Blue LED light therapy is fantastic when used in conjunction with red or near-infrared for the treatment of mild to severe acne in adolescents and adults, acne scarring, and skin maintenance to prevent further acne outbreaks.

Blue light treatment is a natural and powerful technique, that targets the follicle to kill p. acnes, the bacteria that grows deep inside the pores, where it feeds off sebum. The near-infrared rejuvenation facial then reduces inflammation in the blemish, speeds up the healing process and improves overall condition of the skin.”

How Many Treatments Do I Need?

The Light Salon recommends you book for a course of ten treatments. “At the end of four to five weeks of two treatments per week, a 50% improvement in skin condition is possible, with improvement continuing and building for up to 12 weeks afterwards,” says Ferguson.

You can book up to three times in a week, and if you’re trying to treat rosacea, eczema or psoriasis then results will be achieved quicker if you have the facials closer together.

After the initial ten treatments, you can “top-up” once per month or just book ad-hoc treatments.

Unlike laser, you don’t need to take any special precautions such as wearing sunscreen before or after, and makeup can be applied right after the treatment. In fact, “near-Infrared 830nm and Red 633nm, actually prepares the skin beautifully for make-up application,” says Ferguson.

"If you don’t live in London, do your research," advises Ferguson. “Whilst LED is a very safe option, it can be used alongside almost every other skincare modality. It’s, therefore, important you are treated by someone who is reputable and knowledgeable about skin, so you know the combination of treatments are being delivered with expertise.”

Treatments at The Light Salon cost from $42.

Laser Facials

Laser beams are powerful things. I’ve had lasers that have blasted away unsightly broken capillaries around my nose and removed pigmentation leaving me with a clear complexion.

“Lasers are specific wavelengths of concentrated light, each different wavelength behaves slightly differently when it is flashed at the skin. Each laser works mainly by being absorbed by something in the skin like pigmentation, blood cells or water. Typically, the laser is attracted to one element and will not be as well absorbed by other elements, meaning we can target specific areas of the skin without affecting others,” explains Thomas.

For anyone wary of lasers, Thomas says this, “Lasers are amazing and can be used to strengthen the skin and keep it healthy, boost collagen levels and balance its functions. To do this, opt for regular gentle laser treatments rather than one-off aggressive treatments.”

Thomas offers a variety of laser facials at D.Thomas Illuminate in Harvey Nichols that combine laser therapy with everything from peels and masks to mesotherapy and LED depending on your skin needs.

Which Laser?

“There are way too many brands to ever break them all down, instead we can look at the technology of the laser. The most popular laser technologies are:

Alexandrite: It’s most commonly used for hair removal in lighter skin types and for treating pigmentation spots.

Nd;yag: It’s great for treating veins, hair removal in darker skins, skin rejuvenation and treating acne.

Copper Bromide: It treats pigmentation including melasma, veins, various lumps and bumps, Rosacea and acne.

Q;switched and Pico: It's best for tattoo removal, but can also be used for skin pigmentation issues and some rejuvenation.

Erbium and C02 lasers: They are both ablative, which means they cause the skin to peel. They are generally used for rejuvenation and for re-texturizing the skin.

Pulse dye laser: They’re most commonly used to treat different types of redness and acne.

IPL: This is not technically a laser, but many people consider it in the same way, it is not as precise as a laser but can be used for hair removal, pigmentation, veins, and rejuvenation.

Brands that are trusted by top laser specialists in the UK are Fotona, Norseld, Cynosure, Syneron Candela, Alma, Fraxel and Palomar, each brand may produce several types of lasers."

How Many Treatments Do I Need?

As you can see from the list above, lasers can tackle a multitude of beauty complaints.

“The results of each condition treated by lasers will be unique to each person, it will depend on the variation of the condition you have, what the triggers for that condition are, the quality of the laser being used and the experience of the person carrying out the treatment,” says Thomas. Here is her guide:

Acne: Laser treatments can promote fantastic results and will help get the skin under control. This normally takes three to six sessions, but because acne is an ongoing condition that is triggered or aggravated by internal hormonal factors you will need top-up treatments to maintain the skin every two to four months unless the internal hormonal issues balance out.

Rosacea: Since it is very similar to acne in its behavior, a similar protocol is followed.

Age management and rejuvenation: This will normally take three to six sessions and several months to get initial results, which can include brightening, smoothing, plumping and tightening. As the aging process does not stop I recommend my clients have treatments every two to four months to maintain the rejuvenation effects and to keep the skin healthy.

Pigmentation: A very tricky issue, since it varies so much. For melasma you need a very specific type of laser, like the Norseld Dual yellow or one of the q;switched lasers that do not heat the skin up, as heat can make melasma worse (so never use laser peels, ILP or Alexandrite for this). The laser needs to be combined with specific pigmentation peels and home care products. It can take three to 12 treatments initially to get melasma under control but ongoing treatment, both in a clinic and at home, is needed.

Sunspots and other pigmentation issues can take one to three treatments initially then depending on how good you are at protecting your skin from the sun, a top-up every six to 24 months.

Veins: They generally respond very well especially on the face, individual veins will normally go in one to two treatments. If an area has a lot of visible veins, then three to four treatments may be needed to treat them all, if you are prone to having visible veins then new veins will continue to appear so a top-up treatment every six to 24 months will be required.

Hair removal: For most areas on the body takes six to eight treatments on average. Initially, it will give very good results, with a top-up treatment needed every one to three years, however, some areas like the face, back and more intimate bikini line areas take many more sessions more like 12 to 16 and then a top-up every nine to 18 months.

Any Precautions Needed?

Each laser has different precautions so in your initial consultation you will be given pre- and post-treatment advice, before some treatments it is good to use specific products to prepare the skin, but again this will vary depending on the treatment.

“With these types of treatments to get the best and safest results you do need to follow the advice given to you. Some treatments will need up to six weeks of no sun exposure while others just two weeks, so work with your practitioner in this respect. Normally after every treatment will be two to four days of very gentle care of your skin, so no stimulation like scrubs, heavy exercise or saunas, we always recommend good daily SPF every day but especially when having treatments,” advises Thomas.

When it comes to booking, Thomas recommends listening to personal recommendations. “Otherwise look for award-winning clinics, particularly those that win the Aesthetic Awards. Of course, the experience of the practitioner is the main MUST, so do check how long they have been working with lasers. Three plus years is a good start,” says Thomas.
