The concept of nanotechnology was inspired after Richard Feynman talk "There's Plenty of Room at the Bottom" at the California Institute of Technology in 1959 (Gribbin and Gribbin 2018) where he discussed the idea in which scientists would be capable of handling individual atoms and molecules.The term "nanotechnology" was then first introduced and used by Professor Norio in 1974 . This approach makes use of blending techniques using formulations having nanoparticles that establish the original skin colour initially followed by the desired skin colour. Nano Medicine: Meaning, Advantages and Disadvantages - BioTechnology Notes Nano-hydroxyapatite is mainly used in oral care products as well as cosmetic products. These nanocapsules are stable in an aqueous medium, biodegradable and biocompatible in nature [102107]. The cosmetic industry has extensive use of nanomaterials for various benefits. The balanced UVA and UVB protection can be achieved through the ZnO dispersions of small nanosized and large microsized particles. SLN and NLC (Nanostructured Lipid Carrier) are widely used as carriers for sunscreens, anti-acne and anti-aging components [8284]. The brief outline of their methods of synthesis has been summarised in table 1. This review gives a brief outline of the advantages as well as disadvantages of nanotechnology in cosmetics. The use of hydroxyapatite nanoparticles also increases the shelf life upto 23 months due to its stable nature [140]. Charging of metallic copper powder and CCl, They improve the texture of cosmetic products, They increase the surface area of products, They infuse enhanced shelf life in the cosmetics. Age-Defence Complete Skincare Collection for Dry / Sensitive Skin, All You Need To Know About Nanoparticles in Cosmetics, The zinc oxide and the titanium dioxide we use is considered fine with particles between 1 and 2 microns. 1 Recommendation. Firstly the review gives a brief outline of the types of nanomaterials used in cosmetic formulations along with their potential benefits followed by different types of nanotechnology-based cosmetics. Moreover the study regarding the toxic effects on the health also equally matters. However, studies suggest that when nanoparticles reach the bloodstream, they may lead to extensive organ damage. The different types of components such as vitamins, antioxidants and other lipid molecules can be delivered with the help of liposomes. The field of nanotechnology is being greatly explored by cosmetic industries in order to improve the efficacy of cosmetic products. The review presents the benefits and the harmful effects of nanoparticles in cosmetics along with a brief insight into the type of nanoparticles majorly used in the cosmetic industry [5, 1214]. Scientists are primarily concerned about the toxicity, characterization and exposure pathways associated with Nano medicine that might pose a serious threat to the human beings and environment. The nanoemulsions are able to reduce the delicacy and oily nature of hair making the hair shiny. Application of JSH18 containing SLN formulations has shown effective recovery of skin coloration in hairless rats within 4 days post-exposure to UV irradiation for a time period of 7 days thus suggesting its potential applicability in skin whitening [122]. The extensive use of nanomaterials in cosmetic products has been attributed to its multi-faceted nature. Nanotechnology-based formulations have been immensely used in different beauty products, skincare products as well as sunscreens, hair care products, deodorants and perfumes in addition to dental products as a result of associated advantages like enhanced performance and high bio-availability [119]. HaCaT cell lines treated with upconversion nanoparticles coated with polyethyleneimine (PEI), polyacrylic acid (PAA) polyethylene glycol- amine (PEG) in the concentration of 250 g per ml for 24 h. Upconversion nanoparticles and nuclei are pseudo-colored in green and blue, respectively. The cosmetic companies such as Dow Chemical Company, L'Oral, Revlon, and Unilever, have registered patents on dendrimer-dependent cosmetic preparations for various applications for skin, nail, and hair care products. On that note, there are some types of nanoparticles that are used to study the penetration of nanoparticles through the skin by optical imaging, which is fluorescent in nature. The European Union Observatory for Nanomaterials (EUON) has set forth the REACH registration compliant (REACH is a Registration, Evaluation, Authorization, and Restriction of Chemicals). The integration of nanoparticles in cosmetics is gaining demand because of their high surface-to-volume ratio which helps in better penetration through the skin [37]. The presence of non-cytotoxicity, biocompatibility, and stability of gold nanoparticles make gold nanoparticles significantly useful in cosmetic formulations [25, 26]. This research explains that aggregated ZnO particles of dimension 130 nm rather than the 20 nm primary particles influence UVA-1 protection [22, 23]. To get an idea how small they are, we will tell you that they are 80,000 times smaller than the width of ahuman hair, or that they are as big as 1/5,000th the thickness of a sheet of paper. In another study, it was revealed that 10 and 50 nm citrate-coated AuNPs did not show toxicity towards embryonic fibroblast cells [28]. While latter includes vice versa as that of the divergent method in which the synthesis starts from the exterior part that ultimately becomes the outermost arm of the final dendrimer [4244]. The solid lipid nanoparticles (SLN) are of sub-micrometer in dimensions. Whenever you apply a nano-enhanced product to your skin, you are taking a risk. The free radicals generated from aluminium oxide nanoparticles were investigated for their induced concentration-dependent stem cell toxicity and produced inflammation that may lead to diseases such as atherosclerosis disrupted the blood-brain barrier and directly toxic to brain blood vessel cells [172174].
