Peptides have emerged as a crucial component in the world of skincare, and their significance is rooted in their remarkable ability to support healthy-looking skin. These small chains of amino acids might seem unassuming, but their impact on skin vitality has been well studied and scientifically validated.

Peptides start at the molecular level. At their core, peptides function as messengers, signaling various processes within the skin. Their presence encourages the production of essential proteins like collagen, elastin, and keratin, which are fundamental for maintaining skin structure, elasticity, and resilience. With age and exposure to environmental stressors, our skin's natural peptide production declines, which can be a factor contributing to signs of aging such as wrinkles, sagging, and loss of firmness.

What makes peptides particularly valuable in skincare is their specificity. Different peptides serve distinct purposes, targeting specific skin concerns. Some peptides focus on supporting key structural components, helping to reduce the look of fine lines and wrinkles in signs of aging. Others assist in improving the look of skin texture and firmness, while certain peptides possess soothing properties, calming signs of redness and irritation making them ideal for sensitive skin.

Peptides can also be optimized for delivery into the skin. Some peptides can even act as delivery molecules, helping to support the delivery of other active ingredients into the skin.

In haircare, peptides can also have a number of benefits, including helping to support healthy-looking hair, by promoting thicker, fuller-looking hair.

At The Ordinary, we believe in the power of peptides, which means we have developed an array of products featuring multi-peptides and these ingredients work concurrently to target the appearance of multiple skin concerns, as well as support hair density.

Our Recommendations for Your Peptide Journey:

Multi-Peptide + HA Serum
Our original multi-peptide serum utilizes four well-studied peptide technologies, skin-friendly amino acids, and multiple hyaluronic acid complexes. It helps significantly improve the appearance of crow's feet, as well as improving the feel of skin elasticity and firmness.

Multi-Peptide Eye Serum
This water-based formula targets multiple eye concerns in one serum. Utilizing multiple peptide technologies it helps to reduce the appearance of crow’s feet and under eye wrinkles, eye bags, puffiness, and dark circles, leaving the eye area looking brighter, smoother and less puffy.

Multi-Peptide Lash and Brow Serum
By utilizing 11 active ingredients, including four peptide complexes and a series of natural extracts, this twice-daily serum works to help nourish and protect your lashes and brows while enhancing the look of density and overall appearance in as little as four weeks.

As you look into layering skincare with peptides, we recommend focusing on your primary concern first. Our peptide serums are water-based, so should be applied after cleansing/toning before emulsions, creams, or oils, and BEFORE Retinol.

To give you a simpler breakdown, here are a few ways in which you can use target peptide solutions:

Ideal for those wanting to introduce target solutions for specific age-related concerns:

• Argireline Solution 10% (expression lines)
• Matrixyl 10% + HA (firmness)

Ideal for those targeting multiple early signs of aging at once:

• Multi-Peptide + HA Serum

Ideal for more advanced age-support:

• Multi-Peptide + Copper Peptides 1% Serum

Ideal for anyone and a good pairing with the above:

• Multi-Peptide Lash and Brow Serum
• Multi-Peptide Serum for Hair Density

Because everyone’s skin is different, everyone will have a unique response to new skincare products. The important thing is to be patient and consistent. As an example, for Multi-Peptide Lash and Brow Serum, results can be seen after 4 weeks of consistent use.

Direct Acids and L-Ascorbic Acid (Vitamin C) can increase the susceptibility of the peptides to hydrolysis (a process of breakdown) due to their low pH, as it can affect the efficacy of the peptides.. Therefore, we recommend using them in separate routines. and before introducing any new skincare products into your regimen, including The Ordinary, patch testing is always recommended. Patch testing can be a way to help ensure that your skin is compatible with the new products before fully incorporating them into your routine.

Are peptides suitable for all skin types?

• Our peptide products are suitable for all skin types.

What’s the difference between Multi-Peptide + HA Serum, Matrixyl 10% + HA, Argireline Solution 10%?

• Argireline Solution 10% is a targeted solution designed to help improve the look of fine lines that develop as a result of facial movement over time, such as those found around the eye area.
• Matrixyl focuses primarily on supporting skin firmness while targeting the look of fine lines.
• Multi-Peptide + HA is a multi-technology formula, designed to target multiple signs of aging at once, including the look of fine lines and wrinkles, firmness and elasticity. This multi-technology formula includes Argireline, Matrixyl, and a number of other peptides to help achieve these results.

How long does it take to see results from using skincare products?

• Results may vary in time, depending on the product, usage and each individual’s skin concern. The key is to remain patient and consistent with usage.

Can peptides target more than signs of aging?

• Peptides remain key ingredients for signs of aging, however, they can also target and support hair density, as well as many other skin concerns such as uneven tone and texture.

Whether you’re new to using peptides or a peptide enthusiast, layering skincare with peptides is a promising avenue for supporting overall healthy-looking skin and hair density.
