How does collagen affect wrinkles?
.
It's true - collagen works on wrinkles. It is, after all, the basic building block of the skin - making up around 70% of its dry weightand. When used regularly, it can visibly smooth crow's feet and fine lines. It also increases skin density and elasticity.
Collagen fibres form a scaffold-like network in the skin that holds tissues together. This helps your skin to retain its structure, not collapse or sagand. Unfortunately, as we age, the body's production of collagen declines.
After the age of 25, the natural synthesis of collagen begins to be less than the need for this protein. As a result, you lose around 1.5% of the valuable building block every yearand you start to see the first wrinkles in the mirror. Fortunately, you can replenish collagen in your body.
Collagen creams - what do they do?
.
Wanting to replenish collagen in the facial skin, it seems sensible to apply it to the complexion in the form of a cream. Collagen cosmetics tempt with promises of smoothing wrinkles and firming the skin. From the packaging and advertising they shout scalpel-free lifts and incredible rejuvenating effects.
It is important to know that creams, gels and serums mainly work on the epidermal layer. And yes, cosmetics with collagen will perfectly moisturise itand. The hydrated epidermis becomes fuller, which visually can give the impression of filling in fine lines and firming the skin.
This will be a very subtle effect, however - you have nothing to count on spectacular results. To expect them, you would have to work from the inside out.
Why is it necessary to work from the inside out?
Why won't collagen cream remove wrinkles?
.
The skin consists of three layersand:
- The epidermis -which is the outer layer. It is where most cosmetics reach.
- Dermis -this is where the network of collagen fibres, blood vessels, glands and hair follicles are located. .
- Subcutaneous tissue - consisting mainly of fat cells, which have a thermo-insulating function.
Even the best face creams with collagen are usually only able to penetrate the epidermis. The collagen molecules in cosmetics are too large to reach the dermisand.
This means that the cosmetic will not be able to affect the collagen structure of the skin. Instead, it can effectively moisturise its outer layer and strengthen its natural protective barrier.

What collagen can help you with wrinkles?
.
What can you do to make sure collagen actually has an anti-wrinkle effect? Replenish its deficiencies in the body. You can do this with the right diet, rich in collagen products. But if you're not particularly fond of pork knuckles, cold legs, giblets and cartilage, you'll find it easier to take collagen in supplement form diet.

How to choose a collagen supplement?
.
Before you start wondering whether you'd rather ingest a pill or add collagen powder to your favourite smoothie, pay attention to the composition of the product.
The ideal dietary supplement contains collagen hydrolysate, which is its best-absorbed formand. If you are not allergic to fish, choose sea collagen. According to research collagen extracted from fish it has the most similar structure to the one we have in our bodies. It is also digested better and faster, meaning it is absorbed more efficiently.
Another important aspect is the daily serving that the product provides you with. Research suggests that an effective serving is between 2,500 mg and 15,000 mg per dayand. For regular supplementation, formulations containing 5,000-10,000 mg of collagen per daily serving are best suited.
Also look out for additional active ingredients. Vitamin C supports the body's natural production of collagenand, a hyaluronic acid ensures proper hydration of tissuesand. These substances thus perfectly complement the action of collagen.
It is also worth looking at whether there are any preservatives, artificial colours, fillers or large amounts of sugar hiding in the composition of the supplement. All of these additives also affect your body, even if they have been approved for use in the food industry.
Particularly if you are taking a supplement.
