Alpha-hydroxy acid(AHA) are used in cosmetic products as a pH adjuster, mild exfoliant and humectant-skin conditioner. Cosmetics containing higher concentration (30%) and lower pH (3.0) of AHA can cause side effects if it is applied without the prescription. For providing information on the safety of AHA and on human risk assessments we studied skin irritation effect of glycolic acid, one of the most commonly used AHA in guinea pigs. The skin irritation by glycolic acid was increased in a dose(10% to 70%), acidity (pH 2.5 to 5.5.) and length of exposure dependent manner (for up to 14 days), respectively. The combination treatment with UVB (0.4 or 3.0 J/$cm^2$) increased glycolic acid-induced skin irritation. Histological examination showed that hyperplasia of non-inflammatory cells in the epidermis of skin treated with high dose of glycolic acid (pH 3.0). There results show that glycolic acid increased skin irritation in a dose, length of exposure and pH dependent manner, respectively, in guinea pig, and the combination with UVB increased glycolic acid-induced skin irritation. The cell proliferation of non-inflammatory cell may be involved in high doses of glycolic acid-induced skin irritation. Long-term application of more than 30% of glycolic acid (pH 3.0) may cause skin irritation.

Lymphangiomas are benign tumors of the lymphatic system characterized by congenital lymphatic malformation such as anastomosis or obstruction of the lymphatic channels. They are most frequently diagnosed in children younger than 2 years, and the lymphangiomas in head and neck represent about 50-75% of all lymphangiomas. Spontaneous regression is rare, and rapid enlargement occurs secondary to infection or trauma. Enlargement may cause serious sequence such as airway obstruction, feeding difficulties, and cosmetic problems. Treatments previously used for lymphangiomas include surgical excision and intralesional injection of sclerosing agents. Problems associated with surgical excision include the risk of scarring, damage to surrounding vital structure and the high risk of incomplete excision. The sclerosing agents previously used have numerous local and systemic side effects as their problems. We present a case of lymphangioma occured in tongue that was treated by surgical excision and sclerotherapy with OK-432.

In clinical dentistry, botulinum toxin is generally used to treat the square jaw, bruxism, and temporomandibular joint diseases. Recently, this procedure has been expanded and applied for cosmetic purposes, and it is becoming a key task to be aware of the precise anatomical structure of the target muscles to be cautious during treatment and how to prevent side effects. Therefore, the purpose of this study is to observe the anatomical structure of the superficial layer of masseter muscle and to provide a most effective botulinum toxin injection method through clinical anatomical consideration. It was observed that the muscle belly of superficial part of the superficial layer was originated from the deep to the aponeurosis of masseter muscle and descend, then changed gradually into the tendon structure attaching to the inferior border of the mandible. In this study, we named this structure deep inferior tendon. This structure was observed in all specimens. We conclude that the use of superficial layer and deep layer injection should be considered to prevent paradoxical masseteric bulging in consideration of the deep inferior tendon of superficial part of superficial layer of masseter muscle.

Parotid deep lobe tumors usually has been treated by total parotidectomy. But there is functional and aesthetic side effects such as post parotidectomy depressions, variable aesthetic deformities, facial nerve injury and Frey's syndrome. Conservative limited deep parotidectomy may result in fewer side effect. Preservation of the superficial lobe for deep lobe tumors could decrease the incidence of complications without any problems in the treatment effect. Additionally, the parotid function preservation and cosmetic appearance after operation also satisfy both the patients and surgeons. We report a case of pleomorphic adenoma of the deep lobe which has been successfully treated by conservative deep parotidectomy.

Sensory irritation is one of the important side effects of cosmetics and it is required to develop new products that are more tolerable to the consumers. There are lots of cosmetic ingredients known to induce sensory irritation such as lactic acid, glycolic acid, ethanol, preservatives, fragrances and menthol etc. It is also known that sensory irritation increases by change of pH as well as additional occlusive conditions. The aim of this study is to know various factors affecting sensory irritation due to preservatives (methylparaben, propylparaben, phenoxyethanol and chlorophenecin). We also wanted to investigate the effect of preservatives to sensory irritation according to change of formulations. Our results showed that sensory irritation increased with the conditions of increasing absorption such as packs. We have also found that sensory irritation increased synergistically when to apply two different preservatives together. For example, phenoxyethanol and chlorphenesin themselves have weak sensory irritation potentials, but we observed phenoxyethanol combined with chlorpenesin synergistically increase of sensory irritation potentials. In conclusion, formulation and combination of different preservatives should be considered to reduce the unwanted sensory irritation of preservatives.

Cosmeceuticals products we not the products simply for moisturizing and protecting skin but the ones for encouraging to make improvements on wrinkles and helping to whiten, tan, and protect skin against ultraviolet light. In a broader sense, they refer to products with aiming to maintain healthy condition of skin such that skin troubles could be improved or aging of skin could be delayed. However, cosmeceuticals should not have any side effects because they are applied to the whole body for a long period of time differing from medical products which are used on specific areas for a short time. The number of such cosmeceuticals has increased from 500 in 2001 to 2300 in 2003. In order to develop and broaden the scope of cosmeceuticals, the concept of cosmetics needs to be changed from caring skin to delaying aging of the skin and reviving cells. For this purpose, high-valued materials should be developed through basic researches related to the biological function of skin, in vivo experiment and reaction of skin in response to various stimuli using biotechnologies and bioengineering methods. At the same time, it should be proceeded to develop new nano materials for overcoming skin barriers and transfer matericals for helping to absorb effective substances and maintaining stability.

There is a growing interest in breast augmentation surgery, which can most effectively maximize femininity, among modern women around the world. However, breast augmentation surgery is considered one of the most terrifying surgeries many women are afraid of, as many cases of its side effects have been reported. As a way to provide a complementary method to deal with it, this study investigated the effects of a non-surgical breast enhancement program by stretching soft tissue of the breast. According to the results, there was no change in body weight and breast elasticity, but there were marked increases in breast cup size, breast diameter and volume of the women who used this program. The external soft tissue expansion system was found to be effective in Korean women's change of breast shape. On the other hand, users should use this system regularly for some period of time, and this would limit their social activities. Therefore, for the effective use of this system, its users should make individual efforts.

Steroid hormone, glucocorticoid (GC) has strong anti-inflammatory effects by binding to glucocorticoid receptor (GR) inhibiting the expression of inflammatory genes. Therefore, agents that activate the GR have been used for the treatment of dermatitis. However, the agents have side effects such as skin barrier dysfunction and dermal atrophy, inducing skin damage as well as skin aging. It has been reported that GC is activated by 11 beta-hydroxysteroid dehydrogenase type 1 ($11{\beta}$-HSD1) to increase the activity of the GR. This study aimed to identify natural materials that can effectively inhibit dexamethasone. We found that alpinetin isolated from Alpinia katsumadai extract has a significant effect on this. Alpinetin not only inhibited $11{\beta}$-HSD1 expression, but also suppressed the increase of phosphorylated GR and cortisol concentration. Alpinetin also recovered collagen expression in dexamethasone-treated dermal fibroblasts, and the reduction of dermal thickness in dexamethasnone-treated 3D skin model. These results suggest that alpinetin prevents skin aging induced by the increase of $11{\beta}$-HSD1 expression.

Purpose: Dramatic improvement of hemangioma to propranolol has been recently reported; however, details on dose and duration of treatment, potential risks, and monitoring have not been determined. The objective of this study is to describe and analyze the use of propranolol as a first-line treatment or as a single therapy in management of complicated hemangioma. Methods: A retrospective chart review of eight patients diagnosed with hemangioma and treated with propranolol in Kangbuk Samsung Hospital from February 2010 to April 2011 was performed. Results: Eight patients with hemangioma with functional impairment, cosmetic disfigurement, or rapid growth were treated with propranolol. Five patients had solitary facial hemangioma. The mean age of symptoms at onset was 5 weeks. The median age for starting propranolol treatment was 5.5 months. Propranolol at 2 mg/kg/day was finally administered in divided doses with a gradual increase. Significant regression was observed in seven patients, and shrinkage in size, softening in consistency, and decrease in redness were evident within 4 weeks. Among them, six patients were still taking propranolol, and one patient had stopped after 12 months. Other one patient did not show significant improvement with satisfactory result after 3 months of propranolol use. Treatment with propranolol was well tolerated and had few side effects. No rebound growth was observed in any of the patients. Conclusion: We observed that use of propranolol was very effective in treatment of hemangioma without obvious adverse effects or relapse.
