Effects of Skin Lightening Cream Agents - Hydroquinone and Kojic Acid, on the Skin of Adult Female Experimental Rats.

ABSTRACT: Introduction:Skin bleaching is the act of using steroid- and chemical-containing products to lighten the skin. Hydroquinone and kojic acid are often used in skin bleaching creams. Hydroquinone was suspected to be harmful. This study investigated the effects of kojic acid and hydroquinone on the skin of adult female Wistar rats and the potential use of aloe vera for amelioration. Materials and Methods:Eighty [n=80] adult female Wistar rats with an average weight of 120 g were randomly divided into eight groups, marked A, B, C, D, E, F, G, and H. Group A animals served as the control group; group B was treated with 2% hydroquinone, group C was treated with 2% kojic acid, group D was treated with 4% hydroquinone, group E was treated with 4% kojic acid, group F was treated with 2% hydroquinone and 2% kojic acid, group G was treated with 4% hydroquinone and 4% kojic acid, and group H was treated with 4% hydroquinone, 4% kojic acid, and aloe vera. The preparations were applied to the tail skin and treatment lasted 28 days. Skin samples were excised and processed using H&E, Masson's trichrome, and p65 immunohistochemical assays on tissue sections. Results:Hydroquinone caused structural disruptions of the stratum corneum of the epidermis and the overlying keratin. p65 was also prominently expressed in the treated groups. Hydroquinone reduced skin thickness and caused epidermis disruption. Discussion:The prominent expression of p65 in the sections indicated deleterious effects of hydroquinone. Kojic acid was not found to have deleterious effects. Aloe vera prevented extensive disruption of stratum corneum by hydroquinone. The use of hydroquinone in skin lightening creams might raise health concerns. Aloe vera could be protective against hydroquinone.

Project description:BackgroundSkin-lightening (SL) products are common, especially in Africa. Adverse effects from these products represent a public health concern. Use of these products in Somaliland is unknown.ObjectiveThis study aimed to determine the prevalence of use of SL products among female health science students, beliefs about these products and practices, and adverse effects experienced.MethodsThis was a cross-sectional survey of a convenience sample of female health science students at Amoud University in Borama, Somaliland.ResultsOf the 400 students who were invited to participate, 265 completed the survey (response rate: 66%). Mean participant age was 21.1 years (standard deviation: 2.0 years). The majority of students were single (91.2%) with a Fitzpatrick skin type of 3 or darker (94.2%). Past or present use of SL products was reported by 25.6% of participants, and 52.2% admitted to current use. Compared with non-users, more SL product users agreed that lighter skin color gives a woman more confidence, helps a woman have better job opportunities, and increases chances of getting married. They also agreed that advertisements on television for SL products influence a women's preference for a lighter skin tone (p < .05). More than 60% of participants were unsure what active ingredients were in their SL products. Only 9% denied any undesirable adverse effects, and the remainder reported an array of local and systemic adverse effects. The vast majority realize that SL products may cause undesirable local (92%) and systemic (89%) adverse effects.LimitationsGeneralizability is limited because a nonrandomized convenience sample from one university was studied. Response bias also may have skewed results.ConclusionUse of SL products among female health science students in Somaliland is common, and causes cutaneous and systemic adverse reactions. Use appears influenced by beliefs about the benefits of lighter skin color. Education is needed on the proper use of these products, how to avoid harmful products, and how to prevent complications.
