As Americans’ life expectancy grows, so too does the demand for restorative products that can act as a “fountain of youth” for wrinkled, sagging skin. At the same time, an increasing number of consumers are aware of the carcinogens found in many cosmetics and facial products. Shoppers want to look young, but they don’t want to put their own health at risk.

Dermatologists suggest peptide-rich facial products, such as Peter Thomas Roth Un-wrinkle Turbo Face Serum, as a safe, effective route to younger-looking skin. Below is an exploration of why peptides are important and what makes the Peter Thomas Roth peptide serum so potent.

Peptides 101

At the most basic level, a peptide is a combination of amino acids, the body’s building blocks for creating proteins. Some peptides contain just two amino acids (these are called dipeptides) while others may string together dozens of amino acids. Although it’s not a firm line, the cut-off for distinguishing a peptide from a protein is generally considered to be fifty amino acids – most proteins have at least this many amino acids.

Why Peptides are Important for Healthy Skin

Dermatologists first became interested in peptides after discovering the role they play in healing wounds. The body creates its own peptides to heal broken skin. Scientists have also discovered that peptides may be combined with other substances, such as copper, to further augment wound healing. On their own or combined with other materials, peptides can spur an increase in collagen production, meaning skin blemishes are healed more quickly and new skin is created more frequently.

Additionally, peptides enhance the effectiveness of antioxidants, ingredients that can help offset wrinkles. Sun damage, smoking, pollution and extreme weather conditions can all cause dull, wrinkled skin to appear. Antioxidants found in vitamins C and E help offset these environmental and lifestyle factors; peptides can make these powerful ingredients even more effective.

Products such as Peter Thomas Roth Un-wrinkle Turbo Face Serum rejuvenate skin with a one-two punch of peptides and antioxidants. In addition to a plethora of peptides, Peter Thomas Roth’s serum contains vitamin C, vitamin E and retinol. These and the other ingredients in Peter Thomas Roth Un-wrinkle Turbo Face Serum are each attached to a palmitate (fatty acid group), which creates a gentler facial care product.

Beyond these basic facets of how peptides promote youthful skin, consider how each type of peptide listed below affects skin health.

1. Signal peptides. Some signal peptides increase collagen production by increasing the activity and number of fibroblasts in skin. Fibroblasts are special cells that connect collagen and extracellular tissue to prompt the creation of new skin. More fibroblasts means more new skin is produced, and wrinkles become less visible. One of the signal peptides included in Peter Thomas Roth Un-wrinkle Turbo Face Serum is palmitoyl pentapeptide, AKA Matrixyl-3000, which has been shown to increase the production of new collagen.

Alternatively, signal peptides can also lend skin a youthful appearance by inhibiting the degradation of collagen and elastin (which keeps the skin flexible).

2. Neurotransmitter-affecting peptides. Botox injections are the most common cosmetic operation – 4.6 million Botox injections occur every year in this country. Botox prevents the development of facial wrinkles by paralyzing underlying muscles. Neurotransmitter-affecting peptides work in a similar way; they prevent the neurotransmitters for muscle contraction from reaching the brain, thereby preventing muscle activation and decreasing the appearance of wrinkles.

Peter Thomas Roth Un-wrinkle Turbo Face Serum contains the peptide acetyl hexapeptide-3, which has been shown to reduce the depth of wrinkles by 30 percent when injected into the skin.

3. Carrier peptides. This type of peptide binds to very small amounts of trace elements required for healthy skin. For instance, the peptide GHK-Cu was originally discovered in human plasma. In the body, one of its main roles is to bind to and distribute copper, which is necessary for new collagen and elastin production.

If you do decide to begin reviving your skin with Peter Thomas Roth Un-wrinkle Turbo Face Serum or another peptide-rich face product, know that peptide-based products work best if applied regularly over a period of two to three months. You will see a noticeable difference in the texture and appearance of your skin after this time. Finally, because this Peter Thomas Roth product can feel a bit sticky directly following application, you’ll want to let it settle in for about a half hour before applying your cosmetics in the morning.
