I've been using Bulkactives green tea EGCG for four years. No complaints, it blends nicely my DIY anti-aging cream. I can feel a bit of toning and definitely notice the anti-inflammatory effects on my skin. Two observations that keep the rating 4 stars instead of 5: (1) A package of green tea contains significantly less weight/volume than the package of grape seed extract that I order from bulkactives. The two are combined in equal amounts in the anti-aging cream, so I find myself running o.. ...»

glycation inhibitor and repair

Glycation (AGEs) inhibitors and repair in skin care

In healthy skin, mechanisms of damage repair are functional. When these mechanisms are impaired, there is an accumulation of damages from molecular modifications, which results in ageing of the skin. The modifications occur mainly in the dermal extracellular matrix (ECM), and glycation of its structural proteins is one of the many modifications that occurs during ageing.[1] Glycation is an intrinsic ageing process where glucose binds to proteins.

The carbonyl groups on free flowing glucose can react with the amino groups on proteins without enzymes and form reversible compounds called Amadori products. These products then undergo a series of complex reactions and form irreversible protein compounds called advanced glycation end-products (AGEs).[1] Just like roasting meat marinated with sugar, glycation reaction gives the proteins a brown color and they are fluorescent under a fluorescence microscope.

AGEs are reactive and can form cross links between targeted proteins through strong covalent bonds, making them less elastic and more prone to breakage, and it also interferes with the repair mechanisms.[1] Moreover, AGEs deplete hyaluronic acids (HA) from the skin,[2] and HA is crucial for maintaining the structure and volume of the skin tissue because it can hold substantial amounts of water.[3] The glycated proteins can be destroyed through natural protein turnover: old proteins being degraded with newly synthesized proteins taking their place.[4]

Other than protein turnover, there has also been documentations of a specific AGE recognizing receptor on macrophages (a type of white blood cell), and AGE-modified proteins are selectively internalized and hence destroyed by macrophages.[5] Furthermore, when exposed with AGEs, the fibroblasts, dendrocytes, and keratinocytes can increase the production of connective tissue such as collagens, speeding up its turnover through upregulating of an AGE receptor called RAGE.[6] However, activation of RAGE also facilitates inflammation and compromises skin integrity.[7]

One of the main target proteins for glycation on ECM is collagen, and since it has a relatively slow turnover rate (about 15 years),[8] it is particularly susceptible to AGE accumulations. The rate of AGE accumulation is proportional to glucose concentration in addition to time. With the presence of fructose, the rate is ten times higher.[7] This is why diabetic patients (who have high circulating glucose and fructose) have more AGEs and abnormalities in their skin,[9][10][11][12] whereas in healthy subjects the glycation of collagen from age 20 to 85 only increases by 33%[10] or a 3.7% increase in collagen fluorescence per year.[13]

Sun exposure facilitates AGE formation, evident by more AGEs in sun-exposed area of skin compared to sun-protected ones.[14] Oxidative stress can also promote glycation,[15] and conversely glycation can produce reactive oxygen species which can further damage the skin. In addition, glycation induces other pathological pathways involved in ageing, such as inflammation.[1] Interestingly, dietary AGE consumption can also glycate target proteins,[16] and cooking methods such as grilling, frying, and roasting produce more AGEs than poaching, boiling, and steaming. Ingesting AGEs also have adverse metabolic effects through changing gut flora such as reducing the absorption of nutrients that can fight AGE formation.[16] The glycated and cross-linked protein aggregates are protease resistant,[15] meaning the protein degradation process is impeded, so prevention is really the key.

There are several ingredients that have been found that can highjack AGE formation.

Most strikingly, Centella asiatica extract has been shown to completely halt AGE formation facilitated by a glycating agent in human skin tissue in vitro.[17] Antioxidants can mitigate oxidative stress and help reduce glycation. Ellagic acid (found in pomegranate peel) has been shown to stimulate collagen synthesis and inhibit an enzyme that degrades collagen in vitro.[18] Vitamin C (also known as ascorbic acid) is required during collagen synthesis,[19] and its concentration is lower in aged skin.[20] Vitamin C treatment has been shown to stimulate collagen synthesis as well and rejuvenate aged skin in a double-blind, split-face study,[21] and a randomized, double-blind trial.[22] Carnosine has rejuvenating effects on fibroblasts and can protect the skin from glycation induced damages.[23] Last, a compound in green tea called (-)-epigallocatechin-3-gallate, also known as EGCG, has been shown to reduce oxidative stress and inflammation and protect the skin from ultraviolet light induced ageing.[24] On the other hand, HA supplementation has been shown to stimulate fibroblast proliferation in vitro,[25] which can help restore the lost volume associated with glycation and ageing.[26]

L-ascorbic acid (vitamin C) is an essential nutrient which has many cosmetic benefits. It is a remarkable antioxidant and can scavenge reactive oxygen species and other free radicals, protecting the skin from oxidative stress. It can stimulate collagen synthesis by promoting cross-linking and stabilizing collagen molecules, upregulating collagen genes, increasing the transcription of the tissue inhibitor of matrix metalloproteinase 1, and inducing fibroblast proliferation. It reduces pigmentation by suppressing tyrosinase, which is important for melanin production. It is an anti-inflammatory agent and can be used to treat inflammatory skin disease such as erythema. Together, L-ascorbic acid provides powerful anti-aging properties and has been shown to reduce wrinkles, improve elasticity, and protect against sun damage. Stability and absorption of L-ascorbic acid is a concern. While the anhydrous L-ascorbic acid might be the most stable form, adding vitamin E not only helps stabilizing L-ascorbic acid, but the two have synergistic effects on anti-aging. Used in: philosopy's turbo booster c powder and SkinCeuticals.

Ascorbyl glucoside (AA-2G) is a vitamin derivative, produced biologically by the reaction between glucose and vitamin C. This addition confers greater stability, compared to relatively unstable pure ascorbic acid, thus allowing for wide usage in pharmacy and cosmetics. AA-2G retains the antioxidant properties of the unmodified vitamin, therefore it is used to prevent radiation damage, cell senescence and skin darkening. It also promotes collagen synthesis, as well as cell proliferation – these mechanisms help improve the appearance of the skin and reduce wrinkles. Furthermore, since AA-2G does not release ascorbic acid instantly, all the listed positive effects are sustained longer and the possibility of adverse effects is reduced, compared to using pure ascorbic acid. All these qualities make AA-2G the most attractive vitamin C derivative for cosmetic use.

Ascorbyl tetraisopalmitate (Tetrahexyldecyl Ascorbate) is a molecule derived from vitamin C and isopalmitic acid. Pure vitamin C has several drawbacks for cosmeceutical use, most important of which is the low stability. Chemically modified vitamin molecules are more stable, and pure vitamin is released from the derivatives inside the body. Therefore, the effects of Tetrahexyldecyl Ascorbate are similar to those of vitamin C, most importantly it is able to act as an antioxidant. Ascorbyl tetraisopalmitate reduces the production of oxidizing agents, which contribute to cell damage after exposure to UV or chemical hazards. This effect is even stronger in the modified molecule than in pure vitamin C. Additionally, Tetrahexyldecyl Ascorbate protects against DNA damage and skin darkening caused by UV exposure. Finally, skin visual appearance is also improved by Ascorbyl tetraisopalmitate, as it promotes collagen synthesis and acts as a hydrating agent in reducing skin roughness.

Carnosine is a compound from two amino acids, produced naturally in the human brain and muscles. Most likely, it performs a protective function – carnosine neutralizes metal ions and is a powerful antioxidant. It is used in skin care to combat oxidative damage to DNA and proteins, such as that caused by UV exposure. Furthermore, carnosine can protect proteins, primarily collagen, from glycation. These qualities make it a promising molecule in the fight against ageing, as carnosine not only protects cellular components, but can improve the visual appearance, reduce roughness and fine lines. It also maintains the barrier function of the skin, both by simple hydration and complex effects in wound healing. Carnosine applications are of special importance to diabetes patients, as it helps alleviate several complications of this disease, among them xerosis, rapid AGE production, and impaired wound healing.

Centella asiatica is a tropical plant that has been used extensively in Indian medicine. It has diverse applications for skin cosmetics: firstly, it is effective in wound care, as it promotes healing of simple, infected, non-healing, or burn wounds, as well as wounds in patients with diabetes, undergoing radiotherapy or steroid medication. Centella is also used for treating scars and preventing or reducing stretch marks. The extract of this plant promotes synthesis of collagen, hydroxyproline, hyaluronic acid and cell growth factors, thus helping to maintain the elasticity, strength and general appearance of healthy skin. It also protects the skin from ageing damage, such as glycation, and UV damage, likely by activating antioxidant synthesis.

Ethyl ascorbic acid is a molecule produced by modifying ascorbic acid, commonly known as vitamin C. This modification is done to increase the molecule’s stability and enhance its transport through skin, as pure vitamin C is easily degraded. In the body, the modifying group is removed and vitamin C is restored in its natural form. Thus, ethylascorbic acid retains the benefits of vitamin C, such as antioxidant activity. Furthermore, it is even more potent in reducing skin darkening after UV exposure. It even has some additional effects, not observed in pure ascorbic acid, such as promoting nerve cell growth or reducing chemotherapy damage. Finally, the slower release also ensures that no toxic effects are observed when using this vitamin C derivative.

Green tea has numerous benefits in almost all aspects of skin care. The main active ingredient, EGCG, is a potent antioxidant, and protects skin from UV damage. This results in reduced wrinkling, increased collagen content, smoother skin, thicker and more elastic epidermis and other visual benefits. Green tea also helps to moisturize the skin and improves the long-term barrier capabilities. Among the numerous clinical benefits are antibacterial and antifungal effects, which make green tea useful in wound care. Most important health effect is the prevention of melanoma and other types of skin cancer, resulting partly from the EGCG capability to neutralize free radicals and activate DNA repair. Since the extract also reduces inflammation and sebum secretion, it is an effective treatment against acne. Finally, green tea has also been proven to reduce hair loss and follicle death. Active ingredient in Teamine™ and ReVive™ lines.

The Palmitoyl oligopeptide and palmitoyl tetrapeptide-7 peptides liposome emulsion contains the peptidespal-ghkand pal-gqp acting in synergy to repair the cutaneous damages of age. By activating the skin’s natural production of collagen, elastin and hyaluronic acid, the peptides work to reduce wrinkles and other signs of aging. Collagen, made up of long strands of amino acids, is really the main building block of skin, giving the skin its smooth, and youthful appearance. As we age, collagen is lost, and this gives way to aged, wrinkled looking skin. When the long strands of amino acids in collagen are broken down they create small chains commonly referred to as peptides. The presence of these peptides signal to the skin that it has lost collagen and the production of more is necessary. The peptides Palmitoyl oligopeptide and palmitoyl tetrapeptide-7 work to mimic the appearance of this broken down collagen, causing your skin to react by producing more collagen, as well as elastin (responsible for the skin’s elasticity, and hyaluronic acid (which plumps up the skin and gives it that healthy, full look).

Pomegranates have been used in medicine since ancient times. The extract of this plant contains many compounds acting synergistically to produce strong antioxidant and anti-inflammatory effects. It also helps maintain collagen levels, both by promoting its synthesis and inhibiting collagen-degrading enzymes. Due to these properties, pomegranate extract has a range of benefits in UV protection – it can be used both to prevent and to reduce sunlight damage (photoageing) after exposure. Furthermore, it is an effective skin whitening agent, used to treat melasma and other hyperpigmentation problems. Finally, faster wound healing is observed when using this extract. Combined with antibacterial, antifungal, anti-inflammatory properties and the ability to increase collagen synthesis, this makes pomegranate extract beneficial in many aspects of wound care.
