What is collagen?
Collagen is much more than just a protein; it's the main structural component of various connective tissues in the human body, including skin, tendons, ligaments and bones. In terms of volume, it constitutes almost 30% of all proteins in the human body, making it the most abundant protein. Along with elastin and hyaluronic acid, it is one of the 3 essential elements for skin, making it supple and resistant;
However, as we age, collagen production decreases and existing collagen is no longer able to maintain itself, causing collagen fibers to stretch: skin becomes less dense and plump, tissues slacken and deep wrinkles appear.
It is estimated that after the age of 25, collagen synthesis declines by 1% each year, and from the age of 60 onwards, collagen production is virtually non-existent. Collagen-based dietary supplements help to offset this loss, preserving the youthfulness of skin and joints.

The benefits of collagen for the skin
As collagen production declines with age, signs of aging begin to appear, including wrinkles, loss of skin firmness, and joint pain. In addition, increased collagen degradation can contribute to problems such as osteoarthritis and osteoporosis.
Taking collagen supplements can help compensate for this reduced production, providing the body with the amino acids needed for collagen synthesis. This can help to:
- Improve skin elasticity and hydration: studies have shown that taking collagen can improve the appearance of the skin, making it firmer and more hydrated.
- Reduce joint pain: Collagen plays a crucial role in maintaining the integrity of cartilage. By taking collagen supplements, some individuals have reported a reduction in joint pain.
- Strengthen bones: Collagen is a major component of bone tissue, and its decline with age can contribute to decreased bone density. Studies suggest that collagen supplementation may have a beneficial effect on bone health.
Collagen and Aesthetic Care
Collagen plays a key role in improving skin health and appearance, and some aesthetic treatments are specifically designed to stimulate its production. Here are a few treatments that help boost collagen production:
Radiofrequency :
Radiofrequency uses energy waves to heat the deep layers of the skin. This heat stimulates collagen production, tightening and firming the skin.
Radiofrequency is effective for treating skin laxity, reducing the appearance of wrinkles and improving facial contours.
Microneedling :
Microneedling involves the use of small needles to create micro-perforations in the skin. This superficial wound triggers the body's natural healing response: increased production of collagen and elastin;
Microneedling is beneficial for reducing acne scars and wrinkles, and improving skin texture and firmness.
Hydrodermabrasion :
Hydrodermabrasion combines exfoliation and hydrating serum infusion.
Although it doesn't directly stimulate collagen production, it prepares the skin to better absorb nutrients and products that promote collagen synthesis.
It is ideal for moisturizing, revitalizing and making the skin more receptive to anti-aging treatments.
HIFU (High Intensity Focused Ultrasound) :
HIFU is a non-invasive technique that uses ultrasound to target the deeper layers of the skin. It generates deep heat, stimulating the production of collagen and elastin;
This treatment is particularly effective for lifting the face and neck, and improving skin elasticity.
Each of these treatments offers a unique approach to stimulating collagen production, contributing to firmer, smoother, younger-looking skin. As estheticians, integrating these treatments into your services can not only improve results for your customers, but also enhance the appeal and value of your esthetic care offerings.
Collagen choice and quality
The quality of collagen is crucial to its effectiveness. Here are some tips for choosing the right product:
- Source and type: There are different types of collagen, some more effective for the skin than others. To offer your customers the best results, opt for products containing type I and III collagen derived from marine sources.
- Purity and formulation: choose products with few additives and preservatives. Good absorption is key, so look for hydrolyzed, low-molecular-weight formulas.
- Form and concentration: Drinkable collagen is the most concentrated form available on the market. On average, 1 stick represents the equivalent of 10 capsules or tablets to obtain an equivalent dose of collagen. The average recommended dose is 5 to 10mg/day.
- Certifications and Reputation: Choose brands that have a good reputation and offer transparency on the origin of their collagen and their manufacturing process.
