In recent years , beauty supplements have become a major trend in the skincare world. They promise to improve the appearance of skin, hair, and nails from within. But what's really behind these supplements? What do the latest scientific studies say about their effectiveness? In this blog post, we'll take a look at current research findings and explain what beauty supplements can actually do.
1. Collagen – The star among beauty supplements
Collagen is undoubtedly one of the best-known and best-selling beauty supplements. Studies show that taking hydrolyzed collagen (collagen broken down into smaller peptides) can have positive effects on the skin. A study published in the Journal of Medical Nutrition and Nutraceuticals found that taking collagen for a period of 4 to 6 weeks led to improved skin elasticity and a reduction in wrinkles.
In conclusion, hydrolyzed collagen can support skin structure by stimulating the body's own collagen production. However, it's important to understand that collagen molecules are too large to penetrate the skin directly, which is why they must be replaced by hydrolyzed peptides to achieve the desired results.
2. Hyaluronic acid – moisture from within
Hyaluronic acid is another popular beauty supplement frequently used in skincare to provide hydration. It is known for its ability to bind large amounts of water, resulting in plump, well-hydrated skin. A clinical study published in the Journal of Clinical and Aesthetic Dermatology showed that daily intake of hyaluronic acid over a period of eight weeks led to a visible improvement in skin hydration and a reduction in fine lines caused by dryness.
In conclusion, hyaluronic acid can help the skin retain moisture and reduce signs of dryness. Its effects are well supported by oral intake, as it builds up moisture levels from within.
3. Vitamin C – The Antioxidant Booster
Vitamin C is another important ingredient in many beauty supplements. As a powerful antioxidant, it protects the skin from free radicals, which are generated by UV radiation and pollution and can accelerate skin aging. A study published in the American Journal of Clinical Nutrition demonstrates that oral intake of vitamin C protects the skin from oxidative stress and stimulates collagen production. It also has a positive effect on skin brightening and can help reduce age spots.
In conclusion, vitamin C is a versatile antioxidant that not only protects the skin from damage, but also stimulates collagen production and contributes to a more even skin tone.
4. Biotin and Zinc – More Beautiful Hair and Nails
Biotin (vitamin B7) and zinc are frequently found in beauty supplements that focus on improving hair and nails. Biotin supports hair growth and promotes nail health, while zinc has anti-inflammatory properties and can stimulate hair growth. Studies, such as one published in the Journal of Dermatology , show that biotin deficiency can lead to hair loss and brittle nails, and supplementation often results in improvements.
Conclusion: Biotin and zinc can support the health of hair and nails by stimulating growth and increasing nail strength.
5. Plant extracts – Natural support for the skin
Plant extracts such as green tea, grape seed, and pomegranate extracts are becoming increasingly popular in beauty supplements due to their antioxidant and anti-inflammatory properties. A study published in the Journal of the American Academy of Dermatology found that taking green tea extract can protect the skin from UV damage and slow down the aging process.
Conclusion: Natural plant extracts offer gentle yet effective protection for the skin and support skin health at the cellular level.
Beauty Supplements – A complementary building block for your skincare
Science shows that beauty supplements can have a positive impact on skin, hair, and nails – especially when combined with good external skincare. However, they should not be considered miracle cures, but rather a complementary component of a comprehensive skincare routine that also includes a healthy diet, adequate hydration, and sun protection.
DOCTOR'S TIP
Combine peptides with collagen supplements in your skincare routine. This combination not only supports collagen production but also provides deep regeneration and a radiant complexion – from the inside out!
