Every woman desires flawless clear skin and perfect complexion. But factors such as free radicals, hormonal changes and sun exposure can damage your skin leading to patchy pigmentation and dark spots, making you look older.
Pigmentation is basically the presence of dark (hyperpigmentation) or light (hypopigmentation) patches on the skin. It is a commonly observed concern. It is not life-threatening, but it can definitely give sleepless nights to those who desire a clear and even skin tone. Before we look at how we can effectively treat pigmentation, first let us understand what causes it.
Our skin has melanocytes. These are cells that produce pigment called melanin which gives skin its color. The number of melanocytes present in our skin determines our skin colour. Melanin apart from giving skin its color, protects our skin from the damaging effects of sun radiation. The more our skin is exposed to sunrays, the more melanin is produced by melanocytes. This excess melanin is then deposited under the skin, which leads to skin tan, darker patches or pigmentation.
A question that might bother you is that how much of sun exposure is bad for the skin. Sun emits two types of rays i.e. UVA and UVB. UVB radiation burns the upper layers of skin (epidermis) leading to sunburns.
UVA radiation on the other hand can penetrate deeper into the skin (dermis) and trigger melanocytes to produce excess melanin leading to pigmentation. Dermis contains blood vessels and nerves and UVA by damaging dermis also leads to premature ageing.
So, if your lifestyle demands being out in the sun or field work, then you're disposing yourself to gradual and persistent pigmentation and ageing. Your skin might start looking dull and prematurely aged. You will be surprised to know that even indoor lighting emits UV rays. Hence make sure that you use sunscreen always whether indoors or outdoors to protect your skin. You must also note that pigmentation not only affects face but can be found in other body areas like neck, arms, back etc.
