Red LED light therapy may reduce inflammation and stimulate the production of collagen, a protein responsible for younger-looking skin that diminishes with age. Blue LED light therapy may destroy acne-causing bacteria (P. acnes).
Our eyes 'see' by detecting the light which is reflected off of objects. Like the red apple in the figure below, our skin is rich with blood, which reflects red light = so our skin looks the best when illuminated with warm red-rich light.
People tend to look the best when illuminated by light bulbs that measure around 2700 kelvins. Most bulbs, whether incandescent, LED, compact fluorescent or halogen, are labeled “soft white/warm white” (2,700-3,000 kelvins), “bright white/cool white” (3,500-4,100 kelvins) or “daylight” (5,000-6,500 kelvins).
Red light has become nearly synonymous with LED treatments both at home and at your doctor's office. There are even NASA studies regarding its wound-healing effects, which makes it an ideal option for anyone battling redness, rosacea, or sensitive skin.
Green light
The light energy lightens and fades over pigmentation, protects it from future discolorations, and improves the skin tone. The green light influences the melanin-producing cells in the skin.
According to Dr Sharad, “Blue LED light is most often used to treat acne. It may do this by reducing activity in the sebaceous glands, so they produce less of the oil that can plug the hair follicles, leading to acne. Blue light may also kill acne-causing bacteria known as Cutibacterium acnes.”
The purple light combines the red and blue lights. It eliminates acne-causing bacteria while reducing facial inflammation and reducing the appearance of acne-related scars. It is therefore highly recommended for people with acne and redness.
Red light is most commonly used to promote circulation. White light penetrates the deepest and works to tighten and reduce inflammation.
Most all lighting designers and interior designers agree that the most flattering light comes from lighting sources with a color temperature of 2700 Kelvins. That's a warm, soft yellow light.
In terms of minimising defects, flat, front lighting from a large source will produce the smoothest looking skin. A red colour bias to the light will also help as this will educe the appearance of small blood vessels. Light from a big window on a overcast day will do this.
Scientists have revealed that wearing the colour red will make you more attractive to the opposite sex. Studies reveal that red is the most attractive colour to both men and women but, curiously, the two genders are attracted to the same colour for different reasons.
For example, blueish LED and fluorescent lights have a very low CRI. It's factually the least flattering for your face, and really, for all things on the earth.
Red is by far the number one most attractive color to most men, but some other contenders are blue, black, pink, and green.
Natural light is – you guessed it – light from the sun. And diffused means there's no harsh dark and bright spots, just evenly-dispersed and soft light. Diffused natural light virtually erases imperfections, makes you look younger/healthier, and emphasizes your eyes.
Blue, of course. Blue connotes competence, trustworthiness, likability, and calm. As stated above, shoppers were attracted to blue-themed storefronts. You might want to wear blue, especially navy, the next time you want to appear trustworthy and likable.
Blush. The most flattering shades for everyone are colors that are neutral like millennial pink, or blush. Not only does it flatter all skin tones, but it gives you that #glow no matter who you are and pairs well with everything!
The 45-Degree Standard. One of the most common photo light placements is at 45 degrees, meaning the light is placed at a 45-degree angle from your subject. At 45 degrees, you are most closely emulating what is referred to as Rembrandt lighting, which produces a natural and generally flattering light on your subject.
For instance, red light is designed to increase circulation and stimulate collagen, making it useful for those who are looking to reduce the appearance of lines and wrinkles, she explains.
Red light penetrates the skin deeper than other visible light and stimulates the mitochondria, which has an anti-inflammatory and rejuvenating effect. Collagen is built in the dermis, the skin is calmed, and wrinkles eventually fade.
Red LED light stimulates collagen and elastin, which can help with anti-aging,” explains esthetician, makeup, and beauty expert Tiara Willis, whose work is centered around treating skin of color.
Yellow light - reduces swelling, redness and inflammation. Used to treat sunburns. Green light - creates a calming effect on skin with anti-inflammatory properties. Lightens hyper pigmentation of spots revealing a brighter complexion.
Blue light treatment is most often used as part of a treatment called photodynamic therapy. This therapy can treat some kinds of skin cancer and precancerous spots known as actinic keratoses. These reddish, scaly patches are caused by severe sun damage.
The purported benefits include an increase in the amount of collagen in the skin, which can reduce the appearance of wrinkles and other stigmata of aging. Other uses of LED light therapy include acne, dermatitis, eczema, psoriasis, rosacea, scarring and sun damage.
LED light therapy should be undertaken when the skin is clean - after removing makeup and thoroughly cleansing the skin, and before you apply any serums, moisturisers or treatments.
ORANGE LIGHT
Reds and oranges in the skin tone are reflected back strongly. This can have a flattering, warm effect on the skin that disguises small blemishes and uneven skin tone.
