Ati-wrikle or ati-agig agets are extesively used i the cosmetic products, for acquirig a youthful, firm ski. Ski agig is a atural pheomeo which caot be reversed but with the help of ovel approaches i the cosmetology techiques, scietist ca delay the process of ageig. Ati-wrikle agets are used topically for the treatig wrikles ad sigs of agig. Hyaluroic acid ad botulium euro-toxis are most the extesively used ati-wrikle agets. This review article provides the cocise details about the leadig ati-wrikle agets, their mechaism of actio, uses ad adverse reactios o the body. Hyaluroic acid ad botulium euro-toxis are discussed i detail alog with cost cosideratios. The future treds i the advacemet of dermatological aesthetics ad ati-wrikles agets have also bee icluded. Keywords: Hyaluroic acid, Sodium hyaluroate, Botulium euro-toxis, Aesthetics, ijectio. 1. Itroductio The Ski For better uderstadig of the mechaism of differet dermal fillers ad ati-wrikle agets it is importat to uderstad the differet layers of the ski. The ski is cotiuous membrae alog with the mucous membraes liig the body s surface. The itegumetary system is formed by the ski ad its derivative structures (see Figure 1-1). The ski is composed of three layers: the epidermis, the dermis ad subcutaeous tissue [1]. Fig 1: Represetatio of cross-sectio of the ski Correspodece Deepika Sodh M. pharm, Departmet of Quality Assurace, Delhi Pharmaceutical Scieces Research Uiversity, (DPSRU/DIPSAR) Delhi, Idia Epidermis The peripheral level, the epidermis, comprises of a particular iterstellar groupig of cells kow as keratiocytes, which sythesizes kerati, a log, threadlike protei with a protective role. The thickess of the epidermis fluctuates i various sorts of ski; it is just 0.05 mm thick o the eyelids, ad is 1.5 mm thick o the palms ad the soles of the feet. The epidermis cotais the melaocytes (the cells i which melaoma builds up), the Lagerhas cells (ivolved i the immue system i the ski), Merkel cells ad sesory erves. The epidermis layer itself is comprised of five sublayers that cooperate to cosistetly rebuild the surface of the ski [1]. ~ 7 ~
The Pharma Iovatio Joural 1. Basal Cell Layer 2. The Squamous Cell Layer 3. The Stratum Graulosum ad the Stratum Lucidum Dermis The ceter layer, the dermis, is essetially made up of the fibrillary auxiliary protei kow as collage. The dermis is situated udereath the epidermis ad is the thickest of the three layers of the ski (1.5 to 4 mm thick), makig up roughly 90 percet of the thickess of the ski. The mai fuctios of the dermis are to regulate temperature ad to supply the epidermis with utriet-saturated blood. Much of the body's water supply is stored withi the dermis. This layer cotais the vast majority of the skis' specific cells ad structures, icludig veis, lymph vessels, hair follicles, sweat orgas, sebaceous orgas, erve edigs, collage ad elasti. [1]. The dermis layer is comprised of two sub layers: 1. The Papillary Layer- the upper, papillary layer, cotais a thi arragemet of collage fibers. The papillary layer supplies utriets to select layers of the epidermis ad regulates temperature. 2. The Reticular Layer- The lower, reticular layer, is thicker ad made of thick collage fibers that are arraged i parallel to the surface of the ski. The reticular layer is deser tha the papillary dermis, ad it stregthes the ski, providig structure ad elasticity. Hypodermis The sub cutis is the deepest layer of the ski ad comprises of a system of fat ad collage cells. The sub cutis is otherwise called the hypodermis or subcutaeous layer, ad capacities as both a separator, ratioig the body's warmth, ad as a safeguard, securig the iteral orgas. It additioally stores fat as a vitality save for the body. The veis, erves, lymph vessels, ad hair follicles likewise cross through this layer. The thickess of the sub cutis layer varies all through the body ad from idividual to idividual. Ski Agig The hallmark of the agig face is loss of subcutaeous volume over the period of time. Cliically, with this loss, oe commoly fids the sigs, most cliicias see routiely, whe cofroted with a patiet cocered with the agig face idicated by, a icrease i facial vasculature ad pigmet alteratios, as well as a icrease i the lies ad wrikles of the ski. This is associated with a thiig of the epidermis \ad with dermal atrophy ad loss of the elastic tissues preset withi the dermis ad with actiic chages with loss of [2, 3] dermal collage Fig 2: portrayig the distictive locales of the ski havig wrikles Agig is the procedure of aggregatio of molecular damages (NOVOSELTEV et.al 2001) [2, 3] i orgas ad life forms, over a time frame, causig loss of some of the prerogative characteristics of youth. Harms are oly substace alteratios of the cell DNA particles i a livig beig. Gathered molecular damages i cellular DNA are called substatial chages. As idicated by the gee, where these trasformatios happe, the physiology of the cell or of the orga chages astoudigly or drastically. Without a doubt, these harms are the oes straightforwardly coected to the obvious sig of the oset of the maturig procedure. The amassig of harms esuig to the basal metabolism prompts to divisio of agig ito two structures- 1.

Upo sythesis of the ICAM1 gee i the edothelium, circulat moocytes ad macrophages roll over ad secrete hydroge peroxide to perform diapedesis across the edothelial liig of the vascular wall. ce i the dermis, the immue cells secrete lythic ezymes ad reactive oxyge species (ROS), to fray a path i the dermis. Macrophages i the dermis ted to release collageases which lead to hydrolysis of collage. Macrophages also release ROS which damage the earby residet cells, such as fibroblasts or keratiocytes. Whe this happes, the damage ca trigger the breakdow of cascade of arachidoic acid ad secrete prostagladis ad leukotriees, which diffuse to the adjacet residet mast cells. Upo bidig these mediators o specific receptors, the residet mast cells release histamie ad TNFα, which i tur stimulate the release of p-selectis ad the eo-sythesis of ICAM-1 i edothelial cells. The cycle is the cotiued ad the micro-iflammatory status is maitaied, leadig to ski agig [2, 3]. Fig.3, (Giacomoi et al., 2000), summarizes the microiflammatory model of ski agig Fig 3: micro iflammatory model of ski agig (I-CAM 1 sythesis) (ref. a mechaistic model for the agig of huma ski by Paolo U.Giacomoi, Gle Rei) 1. Photoagig or Extrisic Agig It is associated with chages i ski structure ad appearace. The greatest source of extrisic agig is accumulatio of chemotactic factor like solar radiatio, gravitatioal attractio, ifectios, electric fields, psychological stress, cigarette smoke, aoxia ad uprotected su exposure (i.e. photo agig). This is largely cofied to the face, eck, hads. Over 80% of facial ski agig is due to low grade chroic UV exposure. Some of characteristics iclude coarse wrikles, rough texture, sallow complexio, mottled pigmetatio ad loss of ski elasticity [1,2]. Ati-Wrikle Agets The treatmets for damaged ski rage from ski care products, to eergy based therapies (lasers, light sources, ad radiofrequecy devices) to fillers ad toxis.
