Girls often think that they do not need to apply sunscreen indoors, it is really a big mistake! Even if you are sitting in the office, that does not mean that you are not exposed! UV Light can go through the windows and blinds to you. And do not be surprised that even without the sun, you are still exposed to UV light.
Do you need to apply sunscreen indoors?
The ultraviolet light is divided into UVA, UVB, UVC, and UVD. The UBA wavelength is the longest, the penetrating power is the strongest, and the carrying ability is the least. It can enter the dermis layer of the skin, causing skin aging. The UVB wavelength is short and the penetrating power is medium. It is difficult to pass through the glass. The energy carried is moderate. When it is irradiated on the skin, most of it will be absorbed by the skin epidermis and will not penetrate into the skin again. However, because of its high energy, it can produce strong photodamage to the skin. The dermal blood vessels in the irradiated area are dilated, and the skin may appear red, swollen, blisters etc.
If your desk in office is close to the window, or if you always take a rest near the window at home, then you should protect your skin from UVA, remember to apply sunscreen products, otherwise it will be easily tanned. Also, indoor protection mainly depends on the PA value, not the SPF value. Therefore, when you choose sun care products, pick the one with a PA logo.
Staying in the office will tan your skin?
In fact, fluorescent lamps, energy-saving lamps, halogen lamps, incandescent lamps, ceiling lamps, televisions, computers, mobile phones, etc., the UVA radiation from these ordinary light sources is equivalent to 1/2000 of the daylight, which is very low and therefore, no special protection is needed. However, if you have to work under strong lighting every day for a long duration such as jewelry store employees and models, then you will need to apply sunscreen to protect your skin from UV darkening and ageing. You will never know what light sources will you be in contact with daily, therefore it is best to wear sun protection skin care everywhere you go!
