It takes around four weeks for the new cell to reach the surface of your skin and during this time, it loses its moisture content quite dramatically. Starting with a water content of approximately 95%, this reduces to less than 1% by the time it is dead and on the surface.

Peptides in Skin Care In addition to retinoids , antioxidants and hydroxyacids such as glycolic acid , peptides show efficacy in preventing and treating premature skin aging. n essence, different peptides produce different biological effects by signaling cells to perform various functions by attaching to "receptors" found on the surface of each skin cell. Functions of peptides in skin care can include: stimulating collagen ; promoting glycosaminoglycan synthesis; stimulating capillary formation and repair; enhancing natural antioxidant defense mechanisms. You can think of peptides as keys, and your skin cell-surface receptors as locks — the wrong peptide will have no positive effect where it is not needed. A study presented at the World Congress of Dermatology in Paris demonstrated that a high-concentration peptide formulation reduced wrinkles by up to 50% and produced faster and similar (although not better) results than retinol over a short period of time. The potential for peptides to produce and enhance such specific, desirable and already natural processes without undesirable side effects are the main reason for their advancing use. Peptides can now be found in a range of skin care products across various markets (medical, spa/department store, supermarket), however cheaper peptide formulas are unlikely to realise much, if any, of their intended purpose: peptides are the most expensive raw materials currently used in cosmeceutical skincare ; skin care manufacturers include ineffective concentrations for the sole purpose of being able to claim the presence of peptides; inadequate vehicles (the base substance of a cosmetic product in which active ingredients rest) hinder absorption. 1. Peptides Signal Your Skin to Make More Collagen When we age collagen is destroyed but not replaced. As a result young, smooth becomes thin and wrinkled over time. One strategy to improve winkles and to make you look younger is to replace lost collagen. When collagen breaks down, it forms specific peptides. These peptides act as a signal to tell your skin it was damaged and to make new collagen. Applying peptides directly to your skin is a way to trick your skin into thinking that it has lost collagen recently and needs to make more. The most popular signal peptide for cosmetic use is palmitoyl pentapeptide (Matrixyl). It can be found in many peptide skin products and might be effective in improving the appearance of fine lines. Be a smart skin care consumer — you can find this active ingredient in Strivectin and many other expensive peptide creams. Yet, it can also be found in the much less expensive products like Oil of Olay’s Regenerist , which I recommend to my patients. 2. Peptides Deliver Copper into Your Skin Because peptides are small, they can penetrate the skin’s protective barriers to get to the deeper layers. When copper is attached to a peptide, the peptide can deliver copper to the living layers of the skin. There is research showing that copper is an effective agent in skin healing which is why it has been used for years to treat chronic wounds. Copper peptides seem to promote collagen production and act as antioxidants. They are needed for natural healing and regeneration of your skin and to help remove damaged collagen. Copper peptides can be found in pricey product lines such as Neova or Osmotics as well as less expensive products like Neutrogena’s Visibly Firm Night Cream . 3. Neuropeptides Might Act Like Botox Some peptides might block transmission of signals from nerves to your facial muscles. In particular, a neuropeptide called argireline has been shown in the laboratory to block the release of neurotransmitters from nerves. If argireline was absorbed all the way through the skin to the level of the muscle, then it might block contraction of the muscle, leading to smoother skin, similar to Botox. However, it would be like pouring a small glass of water onto a mattress and expecting it to soak through the underside of your box spring– it’s very unlikely. Neuropeptides are sold in products often called wrinkle-relax creams and are a big part of Dr. Perricone’s line. There are plenty of anecdotal stories of their efficacy but essentially no good published scientific data. Although they sound great, until there are good studies to show they actually work, I would skip neuropeptides for now. Peptides Might Not Do Anything There are many things that have to go right in order for peptides to actually have a benefit. Because they are break-down products of proteins, they have to be stabilized or they might continue to break down further in a topical cream, becoming useless. Also, they have to be in a cream that allows them to penetrate the skin. If a great peptide is in a thick cream that only sits on the surface, then it will never penetrate and will eventually be washed off, without any benefit. That being said, signal peptides and copper peptides seem to have the most evidence for their efficacy and can be found in products that cost less than a tank of gas. Portulacca improving the aesthetic appearance of skin, particularly, preventing, ameliorating, treating and/or reducing fine lines and/or wrinkles. More particularly, the present invention relates to the use of topical compositions containing extract from the Portulaca oleracea plant to treat signs of dermatological aging, especially facial lines and deep wrinkles, and/or improve the aesthetic appearance of the skin. Preferably, the composition is applied once daily to the skin
