Invisible light is electromagnetic radiation that is outside of the visible spectrum. The visible spectrum is the range of light that can be seen by the human eye. It is made up of wavelengths that are between 380 and 700 nanometers. Invisible light includes radiation with wavelengths that are shorter or longer than visible light. There are two types of invisible light: ultraviolet (UV) radiation and infrared (IR) radiation.
UV radiation is a type of invisible light that has a shorter wavelength than visible light. It is responsible for causing sunburn, premature aging of the skin, and an increased risk of skin cancer. It can also cause damage to the eyes, including cataracts and other eye conditions. Beauty professionals and estheticians should be aware of the harmful effects of UV radiation on the skin and take steps to protect their clients from overexposure to the sun.
IR radiation is a type of invisible light that has a longer wavelength than visible light. It is responsible for producing heat, and is often used in beauty treatments such as infrared saunas and IPL (intense pulsed light) therapy. IR radiation can penetrate deeper into the skin than visible light, making it useful for treating conditions such as acne, rosacea, and hyperpigmentation.
UV rays, which are a component of sunlight, can harm the skin in various ways. UVB can cause skin burns, while UVA can penetrate deeply and harm collagen, elastin, and deeper skin cells, thereby compromising the skin’s integrity and potentially leading to premature aging. Both UVA and UVB are known to contribute to the development of skin cancer.
UV and IR light are both invisible, which means we could potentially be exposed to them without realizing it and suffer from any side effects associated with these invisible lights.
