Unprotected sun exposure is the number one culprit for ageing, damaged skin. UV damages the skin by entering the dermis (the middle layer of skin) and breaking collagen down faster. UV also causes free radicals which break down collagen further by increasing the enzymes in the skin.
Factors which can lead to collagen degradation include ageing (this is the main cause), disease, exposure to UV radiation and smoking. A typical form of collagen degradation associated with smoking is the loss of collagen in the skin, leading to premature ageing of the epidermis (i.e. wrinkles).
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.
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.
Hot dogs, pepperoni, bacon, and sausage are all examples of processed meats that can be harmful to the skin. These meats are high in sodium, saturated fats, and sulfite, which can all dehydrate the skin and weaken collagen by causing inflammation.
“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.
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.)
"It's worth remembering that coffee doesn't destroy collagen, it inhibits its production," says nutritional therapist at the Pulse Light Clinic, Lisa Borg.
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.
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.
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.
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.
A diet full of protein-rich foods, whether from plant or animal sources, can help supply these critical amino acids. Other nutrients that aid the process of collagen production include zinc, vitamin C, and copper. So, fruits and vegetables high in vitamins and minerals are also a friend to supple skin.
There are a few ways that exercise can boost collagen levels: Exercise delivers nutrients, like vitamins and oxygen, to skin cells, helping them repair and multiply. Specifically, these nutrients feed the fibroblast cells in your skin that produce collagen.
You can consume collagen by either eating it naturally through whole foods (e.g. bone broth, organ meats, etc.) or choosing hydrolyzed peptides in supplement form. Collagen has also been linked to skincare products and injections, but neither helps your body's collagen production — collagen protein must be ingested.
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.
