UV damage is the main cause of skin collagen loss accounting for up to 80-90% of the appearance of skin aging. UV exposure causes both, less collagen to be produced, and. it also increases collagen degradation via matrix metalloproteinases (MMPs) and other proteases in the skin.
Your body begins to lose collagen when you turn 30. The effects become noticeable after several years. Even though this is a natural process, it's possible to speed it up with UV exposure, pollution, bad habits, and poor diet choices. While it's possible to accelerate collagen loss, it's also possible to slow it down.
Collagen levels decrease with age and, unfortunately, there's no way to prevent this. The good news is that there are several cosmetic treatments that can rebuild or restore collagen.
Collagen can't be absorbed by the body in its whole form. This means collagen proteins must be broken down into smaller peptides or amino acids before they can be absorbed.
Collagen loss due to increase in age
This is the reason why aging skin looks thin, pale and translucent. There may be large spots that are pigmented when some areas are exposed to sunlight. The various alterations in the connective tissue may decrease the strength of the skin and its elasticity.
Ultraviolet rays, aka sunlight, cause collagen to break down faster. With sun exposure, those UV rays damage the skin by entering the dermis (the second and thickest layer of our skin) which causes collagen to break down faster.
Eating foods rich in vitamin C and amino acids can increase the levels of hyaluronic acid and collagen in the body as both are important for skin. Foods such as oranges, red peppers, kale, Brussels sprouts, broccoli, and strawberries are all rich in vitamin C.
Collagen can be restored, because when these treatments happen, the body forms new collagen to repair damage and injuries. Alternatively, food is an excellent way to stimulate collagen production, leading to its restoration within the body.
To make collagen—or any protein—your body combines amino acids. You can get amino acids by eating and digesting protein-rich foods, like meat, beans, and dairy products, according to the Cleveland Clinic. Then your body can repurpose the amino acids into collagen.
What causes loss of skin elasticity? Young skin contains plenty of collagen and elastin, the proteins which give skin its structure and ability to stretch. As we age, these start to decline due to hormonal changes and our ability to heal also slows down, leading to decreased skin elasticity.
“UV exposure can lead to the breakdown of collagen, which can lead to the appearance of fine lines and wrinkles, so you're never too young to start wearing sunscreen regularly,” says Garshick. The American Academy of Dermatology recommends choosing a broad-spectrum sunscreen with SPF 30 or higher.
Symptoms and Causes
Some researchers think they may develop because certain bacteria, viruses or drugs lead to changes in your immune system. Some autoimmune diseases, such as lupus, tend to run in families. Inherited collagen vascular diseases occur because of gene mutations.
Besides time, three main things will lower your collagen levels: sunlight, smoking, and sugar. Too much exposure to ultraviolet light makes its fibers unravel. This can lead to sun damage, such as wrinkles.
How can I naturally rebuild collagen? You can naturally support the collagen production process by using topicals such as vitamin C and retinol, collagen peptide supplements, eating a nutrient rich diet, and avoiding habits that damage the collagen (such as poor sleep and sun exposure.)
Vitamin C (Vit C) benefits to human skin physiology notably by stimulating the biosynthesis of collagen. The main cutaneous collagens are types I and III, which are less synthesized with aging. Vit C is one of the main promotors of collagen formation but it poorly bypasses the epidermis stratum corneum barrier.
Collagen replacement therapy is a safe, non-surgical procedure that replenishes depleted collagen by injecting skin with highly purified bovine (cow) collagen. This collagen is so similar to human collagen that your body will readily accept it as its own.
Over time, continued stress can have adverse impacts on your skin and other body systems. For example, excess cortisol can accelerate loss of collagen and elastin, the proteins responsible for youthful skin texture.
Generally, collagen takes about 8 to 12 weeks to see its major results on skin health, joint pain relief and bone strengthening.
Since the loss of collagen leads to the dehydration and thinning of the skin, wrinkles and fine lines begin to appear. Hair begins to thin and stops looking as healthy as it did before. You may also notice hair loss. As the amount of collagen starts decreasing, hair could begin to split and break.
