What is the action of light on our body?
To talk about the action of light on our skin, we still need to know what we are talking about. While we tend to talk about light as if there is only one, there are actually many types of light. For example, natural light, that of the sun, consists of ultraviolet (UV) light and infrared light. Ultraviolet light itself includes three types of UV:
- UVC, which is blocked by the earth’s atmosphere, and therefore never comes into contact with the skin. Fortunately, because the shorter the wavelength of UV rays, the more they can represent a health risk. UVC has the shortest wavelength, at 190 to 290 nm. Their intensity would therefore cause a severe molecular alteration in humans.
- UVA rays which can cause premature skin aging. With a wavelength of 320 to 400nm, 98% of UV that reaches Earth is UVA. UVA has great power to penetrate the skin, 20 to 30% of UVA reaches the middle dermis. When these penetrate the skin, they stimulate the production of free radicals, which largely contribute to skin aging. Repeated exposure to UVA will tend to thin the epidermis, causing wrinkles and pigment spots to appear .
- UVB which allows the skin to tan, but also to produce vitamin D necessary for the proper functioning of the body. They represent only 2% of UV reaching Earth, with a wavelength of 290 to 320 nm. Exposure to UVB must be limited because it causes sunburn, but also cases of skin cancer. Indeed, with their high energetic power, UVB can cause DNA damage, following cellular disorders.
Light is essential for our body
As you will have understood, light is crucial in our lives, particularly for the production of vitamin D. A mission which should not be taken lightly since vitamin D is essential for the proper functioning of the human body. It stimulates the production of calcium and phosphorus, which gives us strong bones and teeth. It also provides energy to the body; a deficiency would cause great fatigue.
Several studies carried out from the 1980s to the present day also demonstrate that sunlight is essential to regulate the internal clock and keep morale high. It also serves as a natural stimulant to the human brain, to guarantee alertness and concentration. In some cases, sunlight can also be a very good treatment for certain skin diseases, but under very specific conditions, under the supervision of a doctor.
What are the benefits of light on our skin?
In recent years, light therapy and phototherapy have revolutionized skin care. Each with its own specificities, they make it possible to meet targeted needs.
Light therapy, or how to take advantage of natural light
Light therapy consists of exposing yourself to light, using a light therapy lamp. This includes several UV filters, which reduce the dangers for your skin compared to exposure to the sun. Light therapy can treat several ailments, depending on the intensity and duration of exposure. A practical and relatively inexpensive solution, since you just need to invest in a lamp (be careful of quality all the same).
Combined with products for problem skin, light therapy helps fight acne. Light helps reduce inflammation, kill certain bacteria that cause acne, and reduce the amount of sebum. A very effective skin care product for problem skin.
If you have stretch marks, light therapy is also ideal. It helps reduce stretch marks, lighten them, to find smooth and unified skin. Of course, it requires a certain number of sessions and perseverance, but when the treatment is combined with creams for stretch marks, the results are impressive.
Phototherapy, a revolution in skin care
If before, studies only looked at natural light, we now know that there are other types of light that we can produce artificially.
Red light, for example, causes stimulation which leads to greater production of elastin and collagen fibers , which helps provide tone to the skin. This tightens up and is less subject to relaxation. During this stimulation, the muscles of the skin, which naturally
contract over time, relax. Expression lines are then largely reduced. Phototherapy, combined with anti-aging treatments, guarantees you to find new youth!
Red light can be combined with blue light, known for its bactericidal properties. This combination is particularly indicated against rosacea, psoriasis, or even acne. Yellow light is just as interesting for its anti-inflammatory and anti-redness effects. It can be ideal in case of stretch marks, or on certain scars.
Phototherapy equipment is now on sale to individuals, be vigilant and follow the conditions of use to the letter. If in doubt, prefer sessions in a specialized office.
Light, friend or enemy of your skin?
To integrate light into your beauty routine, you must use it sparingly and follow a few precautions. If you expose yourself to sunlight, be careful not to expose yourself for too long, too often. Protect yourself from the harmful effects of UVA and UVB with sunscreen suited to your skin type.
Phototherapy, for its part, has some contraindications: it should be avoided for people suffering from epilepsy, as the light can be pulsed. Risks of photoallergic reactions or skin cancers have also been noted, although they remain rare. Of course, phototherapy should be avoided if you are undergoing treatment with photosensitive substances, just like light therapy.
If the eyes are protected during phototherapy sessions, this is not the case during light therapy sessions, because the light is less aggressive and is not dangerous for the retina. However, light therapy is not recommended for people suffering from ophthalmic
pathologies or with predispositions (cataract, glaucoma, chronic conjunctivitis).
Highlighting your skin, the right actions, the right care
Inspired by these virtues, many cosmetic companies has designed cosmetics that take advantage of natural light to enhance your skin.
