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.
The collagen tissues support the formation of bones, tendons, and cartilage that form depending on the level of mineralization. However, an individual can lose collagen components in the body due to exposure to ultraviolet light, tobacco, excessive intake of sugar, and aging.
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.
You can do this by eating more collagen-rich foods or taking supplements. Additionally, we recommend reducing your exposure to UV rays and the amount you smoke.
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.)
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.
So what's the best way to rebuild collagen in your face? Tretinoin, a prescription-grade retinoid, is an excellent treatment for rebuilding collagen. Almost 30 years ago, a small study showed that tretinoin application increases collagen by up to 80% in the skin after 1 year of treatment.
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.
Collagen restoration results may become visible immediately. But collagen growth can take up to 12 weeks to complete. It is also important to note that the result is not permanent. It means that you need to undergo another procedure or follow-up treatment to further encourage collagen growth.
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.
“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.
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.
Vitamin C
“Like vitamin A, vitamin C supports collagen synthesis in the body, so combining collagen with vitamin C-rich foods or a vitamin C supplement is a win-win,” says Dr. Josh Axe, D.N.M., C.N.S., D.C., founder of Ancient Nutrition and member of The Vitamin Shoppe Wellness Council.
Fruits and Vegetables
Eating foods rich in this nutrient encourages the body to make its own collagen and keep you healthy and strong. Examples of foods with high amounts of vitamin C include fruits such as blueberries, papaya, or citrus, and vegetables like broccoli, leafy greens, and cauliflower.
Does collagen work? Some studies show that taking collagen supplements for several months can improve skin elasticity, (i.e., wrinkles and roughness) as well as signs of aging. Others have shown that consuming collagen can increase density in bones weakened with age and can improve joint, back and knee pain.
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. This can lead to premature wrinkling and sagging skin.
Hyaluronic Acid
One study suggests that hyaluronic acid can help boost collagen production in the human body. Hyaluronic acid is naturally found in the body, but it decreases as we age. However, without adequate levels of vitamin C, your body will not gain the full benefit of foods containing hyaluronic acid.
Exercise stimulates the production of collagen. “Studies show that collagen is in a constant cycle of creation and destruction in the body; age and environment play a factor in the breakdown,” Redpath adds.
