Skin aging is an inevitable process that begins around the age of 25, with some factors being from heredity and lifestyle. During the aging process, every cell in the body slows down and an imbalance at the cell communication level occurs. This imbalance is commonly the cause for the skin’s failure to renew itself, thinning of the dermal layer, and loss of muscle tone.
Fine Lines and wrinkles are some of the first visible signs of aging to the face. Fine lines are small shallow wrinkles, that become noticeable around the eyes at the top of the cheeks; referred to as laugh-lines or crow’s feet. Wrinkles are typically deeper than fine lines, and may stay on the skin even when our face is at rest. They may first appear on the forehead as horizontal lines. And because they result from facial expressions, they will most likely become more pronounced and deeper as time goes by. Deeper wrinkles such as the nasolabial folds can form in the crease between the nose and mouth, and will also deepen over time. Wrinkles related to skin sagging result when thinning and sagging skin shifts downward on the face, and folds and creases may appear as a result. Our skin is a complex organ, and aging occurs on all three of its layers in different ways. These layers are the epidermis, dermis and subdermal or lipid layer. In the epidermal layer, slower cell turnover and reduced sebum production means roughness and dryness on the skin’s surface. The epidermal layer also becomes more sensitive to UV light as it ages, increasing the level of damage. Immune function reduction due to aging means that the skin repairs itself more slowly, making it more prone to delayed wound closure and infection. There is a 1% reduction of collagen in the skin’s dermal layer after the age of 25. Collagen and elastin are the building blocks of the skin, and their decline causes dermal tissue disorganization. When skin structure is weak, fine lines and wrinkles are more easily formed.
It is imperative that clinical skin care be part of your daily regime for anti-aging and premature aging, as well as a active SPF sunscreen of a minimum of 30 be used; even while indoors. In general we spend 4.5-5 hours of screen time in front of blue light devices causes damage to our skin DNA. Blue light, part of the spectrum of visible light, is a high-energy, short-wavelength light (not to be confused with UVA or UVB rays)
So, what exactly is the blue light doing?
Dermatologists have good evidence to show that visible light triggers certain skin conditions, such as melasma, where the skin is stimulated to produce more pigment, There's also evidence that as blue light penetrates the skin, reactive oxygen species are generated, which leads to DNA damage, thereby causing inflammation and the breakdown of healthy collagen and elastin, as well as hyperpigmentation.
Take care of your skin, focus on corrective and preventative treatments and skin care.
