Peptides

What Are Peptides (Skincare)?

Peptides are short chains of amino acids that serve as building blocks for proteins in the body.

How Does It Work in the Body?

Peptides work by signalling to the body's cells to produce more of specific proteins. When applied to the skin, they bind to receptors on the surface of cells, activating various biological processes.

Scientific Benefits

Several studies have investigated the effects of peptides in skincare. Another study published in Dermatologic Surgery demonstrated that peptides can reduce the visibility of fine lines and wrinkles after regular use. Various types of peptides, such as signal peptides, carrier peptides, and enzyme inhibitors, have specific roles in skincare and can provide different benefits depending on their composition.

Dosage and Recommendations

There are no universal guidelines for the dosage of peptides in skincare, as they are typically included in products such as creams, serums, or masks. For best results, it is recommended to follow the manufacturer's instructions. Generally, products containing peptides should be applied to clean, dry skin before applying moisturiser. It is also important to use the products consistently to see long-term results.

Best Sources and Forms

Peptides are available in various forms in skincare products, including:

• Serums 2d concentrated formulations that quickly penetrate the skin.
• Creams 2d moisturising products that provide long-lasting effects.

Some of the most effective peptides include:

• Argireline (Acetyl Hexapeptide-8) 2d known for its wrinkle-reducing properties.
• Syn-Ake (Dipeptide Diaminobutyroyl Benzylamide Diacetate) 2d has a Botox-like effect.

Side Effects and Warnings

Peptides are generally considered safe for skincare use. However, as with all products, some individuals may experience irritation or allergic reactions. It is important to perform a patch test before using a new product containing peptides, especially if you have sensitive skin. If irritation occurs, discontinue use and consult a dermatologist.

Frequently Asked Questions

1. Can peptides really reduce wrinkles?

2. How long does it take to see results with peptides?

Results may vary, but many users report improvements within 4-12 weeks of regular use.

3. Are peptides safe for sensitive skin?

Most peptides are safe for sensitive skin, but it is always a good idea to perform a patch test first to avoid irritation.

4. Can I use peptides together with other active ingredients?

Yes, peptides can be used alongside other active ingredients such as hyaluronic acid, vitamin C, and retinol. However, it may be beneficial to alternate use to observe how your skin reacts.

5. Are there any natural sources of peptides?

Yes, certain foods like soy, milk, and eggs contain natural peptides, but they are generally more effective in concentrated forms found in skincare products.
