• Methods for treatment of sundamaged human skin with retinoids
  申请人：Kligman, Albert M.

  公开号：EP0253393A2

  公开（公告）日：1988-01-20

  Various effects of photoaging or sundamage of skin including impairment of differentiation of epidermal epithelial cells and loss of collagen fibers, abnormal changes in elastic fibers and deterioration of small blood vessels in the dermis of the skin are retarded by applying topically to the epidermis in a maintenance therapy program effective amounts of retinoids including retinoid derivatives and stereoisomers thereof such that epithelial growths are substantially reduced and prevented and the skin substantially regains and maintains its firmness, turgor and elasticity. Moreover, with persistent treatment dermal blood cells and vessels increase and the epidermis and dermis thicken, resulting in improved ability of the skin to sense, resist and recover from irritation or injury. Further, hyperpigmentation, lines and wrinkles due to aging are reduced and prevented. The treatment is particularly useful for human facial skin and preferably applied in amounts insufficient to cause excessive irritation.

  通过在维持治疗方案中向表皮局部施用有效量的维甲酸（包括维甲酸衍生物及其立体异构体），可延缓皮肤光老化或日晒损伤的各种影响，包括表皮上皮细胞分化障碍和胶原纤维的丧失、弹性纤维的异常变化以及皮肤真皮层小血管的退化，从而大大减少和防止上皮增生，并使皮肤大大恢复和保持其紧致度、韧性和弹性。此外，在坚持治疗的情况下，真皮血细胞和血管会增加，表皮和真皮会变厚，从而提高皮肤对刺激或损伤的感知、抵抗和恢复能力。此外，还能减少和预防色素沉着、细纹和因衰老产生的皱纹。这种疗法尤其适用于人的面部皮肤，其用量最好不足以造成过度刺激。

• Use of retinoids for preventing and reducing the size of striae distensae lesions
  申请人：Kligman, Albert M.

  公开号：EP0415458A2

  公开（公告）日：1991-03-06

  Striae distensae lesions may be prevented and/or reduced in size by topically applying to the skin affected with the lesions an effective amount of a retinoid, preferably retinoic acid, preferably by daily application in a dermatologically acceptable vehicle, such as a cream base, at a concentration of about 0.025 to 0.1 weight percent retinoic acid. When applied during the striae rubrae stage, the retinoid may be effective to prevent the formation of striae albae lesions, and when applied in either stage, the retinoid may be effective to reduce the width and depth of the lesions, with improved texture and softness.

  可通过在受皮损影响的皮肤上局部施用有效量的维甲酸（最好是维甲酸）来防止和/或缩小红斑皮损，维甲酸的浓度最好为 0.025 至 0.1 重量百分比。在红斑期施用时，维甲酸可有效防止白斑的形成；在任何一个阶段施用时，维甲酸可有效减少皮损的宽度和深度，并改善质地和柔软度。
