The skin has over 300 natural chemical messengers that regulate skin activity including repair processes. Advances in cosmetic science have helped discover ‘peptides’ that act as chemical messengers within the skin and promoting certain desired activity. Peptides have been generally gold dusted (in low concentrations) in products due to their high costs of production.

Peptides can regulate melanin, increase collagen, decrease inflammation depending on their molecular complex. 8 of the most well studied peptides from clinical studies are packed in this formulation in concentrations well above the recommended levels. The serum has a gel like consistency due to high concentration of hyaluronic acid. Due to high concentration of all actives as well as hyaluronic acid only 2-3 drops of this serum are required.

Tips & Suggestions by CosmeDocs

  • Can be used as an eye serum along with the face also as pH not very low
  • Great to use for dry skin or combat mild side-effects of l-ascorbic acid and/or retinols as it is a well moisturising product; despite using 2-3 drops only.

Frequently Asked Questions

Proteins like collagen, elastin, and keratin are made up of peptides, which are short chains of amino acids.

These proteins are the building blocks of your skin, determining its texture, firmness, and resiliency.

Your skin is less robust without peptides, which can result in a loss of firmness, the formation of wrinkles, a change in texture, and less’ bounce.’

When applied topically to the skin, peptides work as tiny messengers, activating skin cells to perform specific jobs such as producing collagen and elastin.

This process encourages your skin to seem and act younger. According to extensive scientific studies, peptides have been found to help your skin on so many levels, including plumping, calming, and nourishing it.

As a matter of fact, yes! You can pair up a retinoid and multi-peptide serum just before your bedtime for ultimate skin rejuvenation.

According to HSF experts, by combining these two ingredients, you not only get the retinoid’s collagen-building benefits but a better penetration of peptides.

This combo of retinoids and multi peptides enhances the firmness of your skin and is also a fantastic anti-ageing duo!

Since multi-peptide serum promotes collagen and elastin in your skin, which tends to decline with age, Stimulate MP is a saviour for ageing skin.

With regular use, your fine lines and wrinkles are plumped up, and overall, the tone and texture of your skin are enhanced. You get to experience a firmer and more taut skin.

Harley Street Formulations has created this versatile cocktail of skin perfecting peptides that can be used in the daytime or at night.

However, our cosmexperts recommend using Stimulate MP in your nighttime skincare regimen to get the most out of your product.

Before applying any other serum or moisturiser, wait 1-2 minutes to let the serum absorb into your skin cells. Avoid using AHAs or other face acids right before or after using peptide serum since this will reduce its effectiveness.

If you are using Stimulate MP regularly for at least 4 weeks, you will be able to notice considerable improvement in the tone and texture of your skin.

Also, make sure to regularly use sunscreen before you step out of your house to prevent premature ageing and wrinkles.

    Having tried several premium brands of different serums over the years and not noticed much difference i couldn’t believe the dramatic effect the Multi-Peptide Serum from Cosmedocs had on my skin. Now my skin looks noticeable more radiant, younger and just smoother. I also use the Revitalise C20 Vitamin C serum before applying the Multi-Peptide Serum. Both bottles last several month because a few drops of each are enough and due to the high concentration of both products are not too expensive but incredible effective!

    By by fine lines, hello hydrated skin with this little beauty! I’ve never had filler under my eyes, I’m 44 and yes Ive had it else where and botox, but by using this around my eyes it has worked a treat for a few years now, and I highly recommend this product. It’s also good if Ive used my retinoids for a few days, I pop a few drops over my face at night on the third night to give my skin a break and give it some hydration back. Good for inflammation. Locks moisture in over my V C 20. Or keep it in your handbag and add a drop in the afternoon if you’re under eyes look a little thirsty! It has other benefits too!
