Peptides represent a billion-dollar market in the pharmaceutical industry, but they can generally only be taken as injections to avoid degradation by stomach enzymes. Scientists at EPFL have now developed a method to generate peptides that resist enzymatic degradation and can be taken orally.

Peptides are short chains of amino acids that occur in our body, in plants or bacteria to control diverse functions. Several peptides are used as drugs such as insulin, which controls the metabolism of sugar, and cyclosporine, which suppresses organ rejection after transplants. More than 40 peptides are already approved as drugs, generating revenues in the billions. There are several hundreds of peptide-based medications currently in clinical trials.

But almost none of these drug-peptides can be taken orally. Since peptides are an important part of food, the stomach and intestines harbor countless enzymes that can degrade them, meaning that most peptide-based medication do not survive the passage through the gastrointestinal tract.

Benefits of Peptides for Skin Health

The benefits of using peptides in your skincare routine are numerous. Here are just a few:

• Boost collagen production: Peptides can help stimulate the production of collagen, which is crucial for maintaining skin elasticity and firmness.
• Reduce the appearance of wrinkles: By promoting collagen synthesis, peptides can help smooth out fine lines and wrinkles, giving your skin a more youthful appearance.
• Improve skin texture: Peptides can help enhance skin cell turnover, resulting in smoother, more even-textured skin.
• Enhance hydration: Some peptides have moisturizing properties, helping to improve the skin’s moisture barrier and prevent moisture loss.
• Protect against environmental damage: Certain peptides have antioxidant properties that can help protect the skin from free radicals and environmental stressors.
• Support skin repair: Peptides can assist in the repair and regeneration of damaged skin cells, helping to improve overall skin health.
• Brighten the complexion: Certain peptides have been found to have brightening properties, helping to even out skin tone and reduce the appearance of dark spots.

Potential Side Effects and Precautions

While peptides are generally safe to use, it’s essential to be aware of any potential side effects or precautions.

Understanding Possible Risks

Sensitive skin types may experience mild irritation or redness when initially using peptide products. If you have sensitive skin, perform a patch test before applying peptides to your entire face. If irritation occurs, discontinue use.

Additionally, if you have any underlying skin conditions or are using prescription skincare medications, it’s always a good idea to consult with a dermatologist before incorporating peptides into your routine.

Who Should Avoid Peptides

While peptides are generally safe for most people to use, there are a few instances where caution is advised. If you are pregnant or breastfeeding, it’s best to consult with your healthcare provider before using peptide products.

If you have any known allergies to specific peptides or ingredients commonly found in peptide products, it’s best to avoid using them to prevent any adverse reactions.

In conclusion, incorporating natural source peptides into your skincare routine can provide numerous benefits for your skin health. Whether derived from animal or plant sources, peptides offer a sustainable and effective solution for improving collagen production, reducing the signs of aging, and achieving a more radiant complexion. Remember to choose responsibly sourced peptide products and consult with a skincare professional if you have any concerns. Embrace the power of peptides and unlock the potential for healthier, more youthful-looking skin!

The Science Behind Peptides

Peptides work by penetrating the deeper layers of the skin and signaling cells to perform specific functions, such as producing more collagen or repairing damaged tissue. Different peptides have different functions, so it’s important to choose the right ones for your skincare needs.

For example, some peptides act as antioxidants, protecting the skin from free radicals and environmental damage. These peptides work tirelessly to neutralize harmful molecules that can cause premature aging and skin damage. By incorporating antioxidant peptides into your skincare routine, you can give your skin an extra layer of defense against the daily onslaught of environmental stressors.

In addition to their antioxidant properties, peptides can also help to retain moisture and improve hydration levels. Certain peptides have the ability to bind water molecules, creating a reservoir of hydration within the skin. This helps to plump up the skin, reducing the appearance of fine lines and wrinkles, and giving you a more youthful complexion.

Furthermore, peptides have been found to have a positive impact on skin texture. By promoting skin cell turnover, peptides can help slough off dead skin cells and reveal a fresher, more even-textured complexion. This can lead to smoother skin that looks and feels healthier.
