The duo you need for radiant skin and supple joints
Meet the dynamic duo of collagen and hyaluronic acid ! These two magical ingredients are the secrets to radiant skin and flexible joints. In this article, dive into the world of beauty and learn how these two superheroes work together to give you a youthful appearance and optimal mobility. Ready to give your well-being a boost?

What is collagen?
Collagen is like the glue that holds our tissues together! It's found in our skin, bones, tendons, hair, and even our nails. It gives our skin its firmness and our joints their flexibility.
What is hyaluronic acid?
Hyaluronic acid is a kind of gel that circulates throughout our bodies. It's present in our skin, joints, and eyes. It's a kind of lubricant that keeps our skin hydrated and supple, and our joints flexible.
What is the difference between collagen and hyaluronic acid?
Collagen is a fibrous protein found in skin, bones, muscles, tendons, and other connective tissues in the body.
Hyaluronic acid is a polysaccharide naturally present in the body, mainly in the skin, joints and connective tissues.
Collagen contributes to the skin's firmness and structure, while hyaluronic acid helps retain moisture and give skin a smooth, plump appearance. Both substances are important for the health and appearance of skin, and their combined use in skin care products can provide synergistic benefits to combat the signs of skin aging.
An essential complementarity between these two ingredients
These two superheroes work together to keep our skin, joints, and tissues healthy.
The multiple benefits of hyaluronic acid and collagen
Skin hydration :
Hyaluronic acid retains water in our skin and collagen forms a barrier so that this water does not evaporate.
Protection against external aggression :
Both substances help protect the skin from damage caused by environmental factors such as UV rays, pollution, and free radicals. Collagen works by strengthening the skin's structure, while hyaluronic acid can act as an antioxidant to neutralize free radicals that can degrade collagen proteins.
Protected joints
By strengthening the structure of cartilage, collagen helps prevent joint degradation and excessive wear. It also provides support for tendons, ligaments, and joint capsules, which helps stabilize joints and reduce the risk of injury. Hyaluronic acid acts as a lubricant and shock absorber in joints. This reduces friction and shock within the joint, decreasing inflammation and irritation that can cause pain.
Structural support
Collagen keeps our tissues firm, while hyaluronic acid keeps them well hydrated.
Promotes healing
At different levels, hyaluronic acid promotes cell migration and tissue regeneration, while collagen provides a supportive structure for new tissue formation.
In short, these two friends team up to keep our skin and joints in shape!
What about vitamin C?
To top it all off, vitamin C is like collagen and hyaluronic acid's superfriend! It helps eliminate free radicals, stimulates collagen and hyaluronic acid production, and helps keep our skin healthy.
Unfortunately, the natural production of these three elements declines with age, which can lead to skin, joint, and connective tissue problems. But don't worry, you can find all three in our Age With Grace supplement, to keep your skin, joints, and tissues in tip-top shape!

What are the best hyaluronic acids and collagens?
The effectiveness of these ingredients can vary depending on several factors, such as product formulation, concentration, manufacturing method, and individual compatibility with skin or other tissues. Therefore, there is no single "best" hyaluronic acid or collagen.
Favor marine collagen
When it comes to collagen, a distinction is made between marine collagen and bovine or porcine collagen. Indeed, marine collagen has an undeniable advantage: it is recognized for its exceptional biocompatibility. In other words, this collagen is extremely well assimilated or absorbed by our bodies. In this respect, it is much more effective than bovine or porcine collagen.
Furthermore, marine collagen is less acidifying for the body than bovine collagen, so it's better for your health! It's therefore preferable to opt for marine collagen.
For example, you can choose a marine collagen powder, such as our Age With Grace collagen supplement . Made with 10g of marine collagen, 3g of prebiotics, 200mg of hyaluronic acid, and 80mg of vitamin C, this extremely rich and comprehensive supplement will cover all your needs.
And its effects on your body are undeniable - and scientifically proven!
- -17% reduction in wrinkles after 1 month
- -25% reduction in wrinkles after 3 months
- +43% dermal density from 3 months

Face creams and food supplements with collagen and hyaluronic acid
When it comes to hyaluronic acid, an ingredient with multiple benefits, there are many facial treatments on the market, and it can be difficult to choose between them all. Choose based on your skin concerns and your preferences in terms of dosage. Also, opt for natural, organic treatments that respect the skin microbiota and are enriched with prebiotics. You'll benefit from the effectiveness of hyaluronic acid thanks to healthy and virtuous products!
Collagen cream or hyaluronic acid?
If you prefer creams to dietary supplements, you can find "pro-collagen" or "collagen booster" facial treatments. However, nothing beats dietary supplements, such as marine collagen powder, in terms of effectiveness.
What about collagen or hyaluronic acid injections?
