In the realm of skincare, the quest for ageless, radiant skin is an enduring pursuit. Many ingredients and compounds have graced the shelves of beauty stores, each promising youthful, glowing skin. Among these, peptides have gained considerable attention for their potential to transform your skin. But what exactly are peptides, and how do they affect your skin? Let's delve into the science behind these remarkable molecules and explore their role in skincare.

What are Peptides?

To understand the significance of peptides in skincare, it's essential to grasp their basic biology. Peptides are short chains of amino acids, the fundamental building blocks of proteins. Proteins, in turn, are crucial for the structure, function, and repair of skin cells. These tiny molecules serve as messengers, instructing cells to perform various functions within the skin.

Types of Peptides in Skincare

There are various types of peptides used in skincare products, each with its specific function. Some of the commonly used peptides include:

Matrixyl: Matrixyl is a popular peptide known for its wrinkle-reducing properties. It stimulates collagen synthesis and can improve skin texture.
Copper Peptides: Copper peptides promote wound healing and help with skin regeneration. They are often used in skincare products targeting scars and pigmentation.
Palmitoyl Tripeptide-1 and Palmitoyl Tetrapeptide-7: These peptides work together to reduce inflammation and improve the skin's natural repair processes.
Acetyl Hexapeptide-8 (Argireline): Argireline is often referred to as "Botox in a bottle" because it temporarily reduces muscle contractions, helping to soften expression lines.

Peptides act as messengers that transmit information between cells, ensuring that various cellular processes occur efficiently.

How Peptides Work in the Skin

Increase Skin Hydration

Some studies showed peptides to promote ceramide production for water hydration. A study was conducted using a Solanum tuberosum (potato) protein hydrolysate. The potato hydrolysate stimulated the lipid metabolism in skin keratinocytes when added to the culture medium (Popa et al., 2006), and induced a stronger increase of the long-chain fatty acid-containing glucosylceramides in aged keratinocytes than in younger ones (Popa et al., 2010). Moreover, besides the effect on glucosylceramide synthases, it was found that the amount of the neutral phospholipids and the gangliosides was significantly induced by the BP-containing potato hydrolysate, suggesting an activation of the PPARs (peroxisome proliferation activated receptors), that are known to trigger the expression of many lipid biosynthesis genes in keratinocytes (Man et al., 2006).

Improve Skin Inflammation and Wrinkles

Some skin inflammations are brought by bacteria and microorganisms. Some studies show that a class of cationic, antimicrobial peptides (AMPs), was found to be involved in the plant's innate immune response, which was one of the main mechanisms of defense against pathogens. AMPs exhibited bactericidal and fungicidal activity, thanks to their amphiphilic structure and positive charge, which facilitated the interaction and integration into the negatively charged microbial membranes.

Peptides aid in wound healing. In recent studies, the wound healing potentialities of a Glycine max (soy) lysate containing BP with amino acid sequences similar to those of ECM proteins present in the human skin, were explored (Tokudome et al., 2012). These ECM-mimetic peptides produced in soy improved wound healing by increasing dermal ECM synthesis, stimulating re-epithelialization, promoting cell adhesion, and supporting tissue regeneration (Chien et al., 2013).

Protein hydrolysates from Triticum vulgare (wheat) have also been produced and proposed as skin and hair-conditioning ingredients in personal care products (Burnett et al., 2018). The BP contained in the hydrolysate, obtained by acidic, enzymatic, or other chemical digestion procedures, has shown to be very effective in vitro in accelerating skin healing and in reducing the release of several inflammatory mediators, such as nitric oxide (NO), Interleukin 6 (IL-6), Tumor Necrosis Factor (TNF) -alpha, and ProstaGlandin E2 (PGE-2) (Sanguigno et al., 2018).

Benefits of Peptides for Skin

Collagen Boosting

Collagen is a vital protein responsible for maintaining skin's elasticity and youthful appearance. Over time, collagen production naturally declines, leading to wrinkles and sagging skin. Peptides, particularly collagen-boosting peptides like palmitoyl pentapeptide-4, stimulate collagen synthesis. Regular use of peptide-rich skincare products can help improve skin's firmness and reduce the appearance of fine lines and wrinkles.

Enhanced Hydration

Peptides play a crucial role in maintaining the skin's moisture balance. Some peptides, such as hyaluronic acid peptides, attract and retain moisture, helping to keep the skin hydrated. Proper hydration is essential for maintaining a healthy skin barrier, preventing dryness, and achieving a plump, youthful complexion.

Skin Repair and Regeneration

Peptides like copper peptides can aid in skin repair and regeneration. They promote the production of essential skin components like glycosaminoglycans and proteoglycans, which are crucial for wound healing and maintaining skin integrity. This property makes peptides a valuable asset in reducing scars and promoting even skin tone.

Reducing Inflammation

Certain peptides possess anti-inflammatory properties, making them beneficial for sensitive or irritated skin. Acetyl tetrapeptide-15, for example, helps soothe skin by modulating the inflammatory response. Peptides can alleviate redness and discomfort, making them a valuable addition to skincare routines for those with sensitive skin conditions like rosacea.

Antioxidant Protection

Peptides can also act as antioxidants, shielding the skin from harmful free radicals that accelerate the aging process. Antioxidant peptides, such as glutathione peptides, neutralize these free radicals, reducing oxidative stress and preventing premature aging. This protection helps maintain the skin's vitality and radiance.

Brightening and Even Skin Tone

Peptides like oligopeptide-68 can assist in reducing the appearance of dark spots and promoting a more even skin tone. By inhibiting melanin production, these peptides can help fade hyperpigmentation and promote a brighter complexion. They are particularly useful for addressing issues like sunspots and post-inflammatory hyperpigmentation.

Improved Absorption of Other Skincare Ingredients

Peptides can also enhance the absorption of other skincare ingredients, maximizing their effectiveness. When included in formulations, peptides can help deliver vitamins, antioxidants, and hydrating agents deeper into the skin, ensuring that your skincare products work to their full potential.

How to Use Peptide for Skin Care

Achieving healthy, youthful-looking skin often requires a well-thought-out skincare routine. Peptide creams, known for their ability to promote collagen production and reduce the signs of aging, have gained popularity in recent years. To make the most of these powerful skincare products, it's essential to understand how to incorporate them effectively into your daily routine. In this step-by-step guide, we'll walk you through the process of using peptide creams, ensuring that you get the best results for your skin.

Clean Face

Before applying any skincare product, including peptide creams, it's crucial to begin with a clean canvas. Use a gentle cleanser to remove makeup, dirt, and excess oils from your face. Cleansing not only prepares your skin for better product absorption but also helps prevent clogged pores.

Pat Your Face Dry

After cleansing, gently pat your face dry with a clean, soft towel. Avoid harsh rubbing, as it can irritate the skin, especially if you have sensitive skin. Leaving your skin slightly damp is acceptable, as it can help with the absorption of the peptide cream.

Dispense the Right Amount of Peptide

Now it's time to apply the peptide cream. Most peptide creams come in a pump or jar. Depending on the product's instructions and your skin's needs, dispense an appropriate amount onto your fingertips. Generally, a pea-sized amount is sufficient for the entire face.

Distribute Product

With the peptide cream on your fingertips, dot it evenly across your forehead, cheeks, nose, and chin. This distribution ensures that the product is spread evenly across your face, promoting consistent results.

Gently Massage into the Skin

Using your fingertips, gently massage the peptide cream into your skin using upward, circular motions. This massaging action not only aids in product absorption but also improves blood circulation, giving your skin a healthy glow.

Pay Special Attention to Problem Areas

If you have specific areas of concern, such as fine lines around your eyes or wrinkles on your forehead, take a little extra time to massage the peptide cream into these problem areas. Be gentle around the delicate eye area to prevent tugging or stretching the skin.

Don't Forget Your Neck

Your neck and décolletage are often neglected in skincare routines, but they can show signs of aging too. Extend the application of the peptide cream to these areas, using upward motions to help maintain firmness and minimize sagging.

Allow the Product to Absorb Vitamin

Give the peptide cream a few minutes to absorb into your skin fully. This waiting period allows the peptides to penetrate the skin's layers and start their work. During this time, you can move on to other steps in your skincare routine, such as applying a moisturizer or sunscreen.

Follow with Sunscreen (Morning Routine)

If you're using peptide cream in your morning routine, it's crucial to follow it up with a broad-spectrum sunscreen. Peptides can make your skin more sensitive to the sun, so protecting your skin from UV damage is essential. Choose a sunscreen with SPF 30 or higher and apply it generously.

Be Consistent

Consistency is key when using peptide creams. For best results, use your chosen peptide cream as directed by the product instructions. Typically, this means applying it once or twice a day, depending on your skin's needs.

As you continue to use the peptide cream over time, pay attention to your skin's changes. Take note of any improvements in fine lines, wrinkles, or overall skin texture. It may take several weeks or even months to see significant results, so patience is essential.
