Background: With aging, the facial folds, grooves, and sagging tissue become more prominent. It is haracterized by loss of the collagen mass in the dermis and an increased array of elastin whirls in the deeper dermis. The aim of this study was to determine whether correction of nasolabial folds could be achieved using an allogeneic collagen product. Methods: Nine healthy volunteers participated in this beforeafter, pilot clinical trial. Human allogeneic collagen (Collagel, Kimia Teb Rahavard Co., Tehran, Iran) was injected in both nasolabial folds of the volunteers. Skin hydration was measured using the Corneometer® 580 device (CK GmbH, Cologne, Germany). Ultrasonic dermal changes were measured using an ultrasonography device (22 MHz, TPM, Germany) before and 24 weeks after the injection. One independent investigator assessed the efficacy using standardized photographs before and 24 weeks after injections. The patients’ satisfaction rate was also evaluated.Results: All patients showed improvement in wrinkles and the mean satisfaction rate on a 0-10 VAS was 7.4±0.5. The hydration of the stratum corneum increased from 32.32±13.54 to 52.61±12.55 and the echo-density of the dermis increased from 8.05±3.18 to 9.55±3.36 μm 24 weeks after the injection (P≤0.05). No treatmentrelated adverse events were reported.Conclusion: Collagel is an effective filler that can provide a safe and effective correction of the nasolabial folds. This correction lasts for at least 24 weeks on ultrasound evaluations. Further larger blind-randomized controlled clinical trials are required to pave the way for suggesting it as a possible therapeutic option.

Background: Sulfur mustard gas is a chemical agent that has been used in many wars, especially in Iran-Iraq war. This chemical agent affects many organs including lungs, eyes and skin, causing numerous acute and chronic lesions including erythema and hyperpigmentation, respectively. This study was conducted to evaluate erythema and melanin in subjects with a history of exposure to sulfur mustard.Methods: This case-control study was done on 309 subjects. They were divided into four groups: sulfur mustard-exposed patients with skin lesions (n=87), sulfur mustard-exposed cases without current skin lesions (n=71), non sulfur mustard-exposed patients with dermatitis (n=78) and normal controls (n=74). Erythema and melanin were measured in 4 areas (forehead, suprasternal, palm and back of hands) by Mexameter MX18 (Courage-Khazaka, Germany).Results: Erythema was significantly lower in suprasternal and palmar aspect of hands in sulfur mustard-exposed patients with dermatitis (P<0.05) while there was no significant difference in other areas. In terms of melanin, there was a significant difference in the dorsal aspect of hands in all four groups (P<0.05), where patients with dermatitis (both sulfur mustard exposed and normal population) had higher levels of melanin, probably due to pruritus in such areas. Forehead melanin of the normal population was also significantly lower than other three groups (P<0.05) while there was no significant difference between the melanin level of sulfur mustard exposed subjects (with or without dermatitis) and patients with dermatitis.Conclusion: Sulfur mustard contact can affect erythema and melanin content of the skin.
