Hydroquinone Essays

The hydroquinone metabolite purified from B. methylotrophicus MHC10 was evaluated for its antibacterial activity against a panel of several Gram-positive and Gram-negative bacterial pathogens. The zone of inhibition was used to evaluate the antagonistic activity of the metabolite. The standard antibiotics Ampicillin and Gentamycin were used as the positive control. Both antibiotics showed high antagonistic activity against all test pathogens. But in the case of P. aeruginosa, the hydroquinone treatment

Hydroquinone is a strong inhibitor of melanin production that has long been established as the most effective ingredient for reducing and potentially eliminating melasma (Source: Journal of Dermatological Science, August, 2001, Supplemental, pages 68–75). In different concentrations it inhibits or prevents skin from making the substance responsible for skin color. Hydroquinone does not bleach the skin, which is why calling it a “bleaching agent” is a misnomer; it can’t remove pigment from the skin

melasma demonstrated that isotretinoin was associated with reduction of pigmentation o Adapalene is naphthoic derivate a potent retinoid in the treatment of melasma. • Randomized double-blind study reported that azelaic acid was as effective as hydroquinone. However, combination of azelaic acid, with tretinoin or glycolic acid may be more effective in the treatment of melasma. This is may be due to combination therapy produces earlier and more pronounced skin lightening • Vitamin C inhibits melanin

wrinkles and lightens dark spots. Prescription retinoids also helps treat acne and used for the prevention of precancerous growths. C. Lighten your brown spots - also known as age spots can be lightened with a bleaching cream which contains hydroquinone. Hydroquinone helps constrain the enzyme in pigment from integrating. D. Consider an anti-wrinkle cream - these creams help stimulate the skin 's production of collagen and elastin lost through the aging and sun damage process. Some effective anti-aging

ability to heal, intense irritation, uneven bleaching, and sever itchy rashes, dryness, and burning. Use of hydroquinone for periods longer than 3 months will cause darkening and thinning the skin. A negative effect known as the "Bleach Panda Effect" can be developed; it makes the skin around the eye thinner and darker that the patient looks like a panda. The study also found that hydroquinone caused worsening or the introduction of skin diseases. Moreover, skin whitening creams contain steroids which

Experiment 4: Thin Layer and Column Chromatography. Name: Matthew Scully ID Number: 16188357 Date of the Experiment: 23rd of February 2018 Introducton: Chromatography is used to separate a mixture into its different components and although there are different types of chromatography (e.g paper, TLC, column, size-exchange, etc.) they all rely on a mobile phase (which may be a gas or liquid) and a stationary

The literature review will begin by constructing a framework defining Melasma and its interventions. According to Hurley, M.E., Guevara, I.L., Gonzales, R.M. and Pandya, A.G., (2002) Melasma is a pigmentation disorder and is common among women of Hispanic and Asian groups arising from biologically active melanocytes, associated with high vascularity in the areas and occurrence of angio-genic factor in the epidermis. At the outset, it is important to understand Melasma as a disorder and explore the

requirement. Actually vitamin K in its reduced form known as hydroquinone is oxidized to oxidized form called as vitamin K epoxide. This reaction cause the amino acid (γ-glutamylcarboxylase) to carboxylate selective glutamic acid residues that is present on vitamin K-dependent proteins. The recycling of vitamin K is carried out by two reactions that reduce vitamin K epoxide (KO) to vitamin K and then vitamin K into vitamin K hydroquinone (KH2; Figure 2). Then, the enzyme vitamin K oxidoreductase catalyzes

who are selling these products can shut down and have less people with being insecure with their own skin. "The desire to be lighter is so great that some people with dark skin knowingly use illegal creams that contain harmful ingredients such as hydroquinone, mercury, and corticosteroids because they are believed to be stronger and thus more effective” (Phoenix 100). In 2009 there was a report of a skin bleaching which made $10 billion by the year of 2020 the company will now reach to $23 billion.

Mercury compounds are readily absorbed through the skin on topical application and have the tendency to accumulate in the body. These products are often applied to large areas of the skin, left on the skin for hours at a time, and used repeatedly for weeks, months or years. Mercury-containing skin lightening cosmetics pose significant risks to users. Mercury absorbed through the skin from lightening products can damage the skin itself, the kidneys, and the nervous system. The symptoms of mercury

eye to appear lighter because the dark spotting and circles that can make one look old because of wrinkles. Most of the eye creams make the skin around the eye to be firmer because it contains ingredients such as vitamin C, vitamin K, caffeine or hydroquinone which help in anti-aging and reducing wrinkles. When applying the eye cream, care must be taken to ensure

Analyzing this two advertisements both from a very popular cereal the 1950’s, we see in the first picture that is not only prompting the cereal but also selling the idea that you need to stay in shape and in to the appealing of men, the sooner you take care of that body the better, how this interaction mother and daughter is based on body shaming. The second images it’s about body shaming now other people and we can see by her pose that she demonstrates this superiority and elegances that the other

History of Phthalocyanine: Phthalocyanine which is not found in nature is derived from the Greek term for naphtha ( rock oil) and cyanine ( dark blue) [1]. The name was first used by Prof Reginald Linstead of the Imperial College Industry. It’s used as a colorant agent in industry because it’s cheap, robust and has an intense absorption at long wavelength of the visible spectrum. The compound was accidentally discovered in 1907 by Braun and Tcherniac who recorded a highly coloured compound after

Vitiligo is a skin condition that results in the loss of pigment. Melanocytes, the melanin or pigment producing cells within the body, are destroyed; therefore, preventing the body from making pigment for both the skin and the hair. As a result, skin develops white patches throughout and hair may turn white or gray at an early age. The skin is an integral part of the human body. It is made up of two layers, the epidermis and the dermis. In addition, there are specialized cells within the integumentary

Introduction Cyclodextrins (CDs) are cyclic oligosaccharides consist of (α-1,4)-linked α-D-glucopyranose units produced by bacterial digestion of cellulose. These structurally related natural products contain a central cavity that was lined by the skeletal carbons and ethereal oxygens of the glucose residues, which gave it a lipophilic character to a certain extent while the outer surface is hydrophilic. The 3D-structure of CDs are shaped like a truncated cone rather than perfect cylinders due to
