Collagen and healthy, smooth skin go hand-in-hand. What does collagen do for the health of your skin, and what factors influence your collagen levels as you get older? Understanding the link between collagen and the condition of your skin can help you keep it looking and feeling healthy for as long as possible.

Skin Changes Throughout Life 

Physical changes in the appearance and texture of skin tend to become more apparent with age. Some of the most common age-related skin complaints include sagging skin, wrinkles and cellulite.

Weight fluctuations can be one factor for skin changes, and we all know that weight goes up and down with age. Skin tends to stretch and relax to accommodate this change in body composition, leaving saggy areas and marks we may not love. Other common age-related skin changes are the appearance of wrinkles and cellulite.

How Collagen Impacts Skin Appearance

The root cause of many age-related skin complaints is the thinning of the dermis — the middle  layer of the skin — caused by cells dividing more slowly. As collagen fibers loosen and unravel with age, the dermis starts to form depressions seen on the surface of the skin. As you age and your collagen production decreases, your skin becomes less able to secrete its natural oils and retain moisture.

Collagen is a natural and key component of skin. In fact, it’s a main part of fibers in your lungs, blood vessels, spleen, liver, muscle and dermis. Your body is continuously producing collagen, but the process doesn’t work quite as well as you get older.

Supplemental Collagen and Skin Health

While Vitamin C can increase the synthesis of natural collagen in your body, taking supplemental collagen is another great option.

A 2019 systematic review published in the Journal of Drugs in Dermatology found that there’s promising evidence for both short- and long-term benefits of collagen supplementation for skin aging. Research has shown that supplemental collagen can improve skin elasticity, hydration and the density of collagen in the skin. This could be helpful for common age-related skin complaints.

Other studies have examined collagen supplementation and cellulite specifically. In a 2015 double-blind, placebo-controlled study, 105 women ages 24-50 years with moderate cellulite either received 2.5 grams of collagen peptides or a placebo daily for 6 months. Cellulite was evaluated at 0, three and six months. The researchers found that those women who took collagen for 6 months improved skin density and waviness due to cellulite, and had a positive impact on skin health.

The link between collagen and wrinkles has also been studied. In a 2004 study involving 20 healthy women ages 40-62 years, participants were given either a collagen-like peptide gel formula or a placebo to apply around the eye skin twice daily for 4 weeks. The researchers found that the women who applied the gel experienced a significant reduction in the total surface of wrinkles as well as total and average length of wrinkles.

Best Collagen For Healthy Skin 

Supplemental collagen comes in several forms, but the most beneficial for healthy skin is hydrolyzed collagen. This means that the collagen has been partially broken down into peptides, making it more bioavailable to your skin. Research shows that Vitamin C plus gelatin and hydrolyzed collagen help increase the body’s natural production of collagen.

INVIGOR8 collagen is hydrolyzed and paired with microencapsulated Vitamin C for the most bioavailable support. Taking the right collagen may help you achieve and maintain your healthiest skin.
