Collagen is the most abundant protein in the human body, and it's responsible for providing structure and strength to our skin, bones, tendons, and ligaments. In the skin, collagen fibers form a scaffold that supports the epidermis, the outermost layer of skin. This scaffold helps to keep skin firm and elastic, and it also plays a role in wound healing.
As we age, our bodies produce less collagen, which can lead to wrinkles, sagging skin, and other signs of aging. However, there are a number of things we can do to protect our collagen and keep our skin looking its best.
In this interview, we speak to dermatologist Dr. Mamina Turegano about the benefits of collagen for skin, and how you can protect and support your collagen levels.
What is Collagen?
Collagen is a protein that is found in all connective tissues of the body, including the skin, bones, tendons, and ligaments. It is responsible for providing structure and strength to these tissues.
What Role Does Collagen Play in Skin?
In the skin, collagen fibers form a scaffold that supports the epidermis, the outermost layer of skin. This scaffold helps to keep skin firm and elastic, and it also plays a role in wound healing.
What are the Benefits of Collagen for Skin?
- Improves skin elasticity: Collagen, along with elastin, is responsible for giving skin its elasticity, or the ability to stretch and snap back into place. As we age, our collagen production decreases, which can lead to sagging skin and wrinkles.
- Reduces wrinkles and fine lines: Collagen helps to fill in wrinkles and fine lines, giving skin a smoother appearance.
- Improves skin hydration: Collagen helps to hold water in the skin, which keeps it hydrated and plump.
- Promotes wound healing: Collagen is essential for wound healing. It helps to form new tissue and repair damaged skin.
What Causes Collagen Decline?
There are a number of factors that can contribute to collagen decline, including:
- Aging: As we age, our bodies produce less collagen. This is a natural process, but it can be accelerated by certain factors, such as sun exposure, smoking, and poor diet.
- Sun exposure: UV rays from the sun can damage collagen fibers, leading to wrinkles and sagging skin.
- Smoking: Smoking damages collagen and elastin, two proteins that are essential for healthy skin.
- Poor diet: A diet that is deficient in vitamins and minerals can lead to collagen decline.
- Chronic diseases: Certain chronic diseases, such as diabetes and lupus, can also lead to collagen decline.
How Can You Protect Against Collagen Decline?
There are a number of things you can do to protect your collagen and keep your skin looking its best, including:
- Use sunscreen: Sunscreen is one of the most important things you can do to protect your skin from collagen damage. Be sure to apply sunscreen every day, even on cloudy days, with other sun protection measures.
- Avoid smoking: Smoking is one of the worst things you can do for your skin. It damages collagen and elastin, leading to wrinkles and sagging skin.
- Eat a healthy diet: A diet that is rich in vitamins and minerals is essential for healthy skin. Be sure to eat plenty of fruits, vegetables, and whole grains.
- Get enough sleep: When you don't get enough sleep, your body produces more cortisol, a hormone that can break down collagen. Aim for 7-8 hours of sleep per night.
- Manage stress: Stress can also lead to the production of cortisol. Find healthy ways to manage stress, such as exercise, yoga, or meditation.
What Ingredients Help to Skin Firmness and Elasticity?
- Vitamin C: Vitamin C is essential to maintain firm and youthful-looking skin. It helps to prevent the appearance of signs of aging caused by environmental damage.
- Retinol: Retinol is a form of vitamin A that helps to increase cellular turnover and improve the youthful apperance of skin. It also helps to improve skin texture and reduce the appearance of wrinkles.
- Peptides: Peptides are short chains of amino acids that function as essential building blocks for proteins crucial to skin structure and integrity. They can also help to improve skin elasticity and firmness.
- Proxylane™: Proxylane is a synthetic ingredient that helps strengthen skin’s extracellular matrix and increases skin elasticity and firmness.
