Acne vulgaris (or cystic acne) is a common disease, characterized by areas of skin with scaly red skin, blackheads and whiteheads, pinheads, pimples, nodules and possibly scarring. Acne affects mostly skin with the densest population of sebaceous follicles; these areas include the face, the upper part of the chest, and the back. Severe acne is inflammatory, but acne can also manifest in noninflammatory forms.2 The lesions are caused by changes in pilosebaceous units, skin structures consisting of a hair follicle and its associated sebaceous gland, changes that require androgen stimulation. Acne occurs most commonly during adolescence, and often continues into adulthood. In adolescence, acne is usually caused by an increase in testosterone, which people of both genders accrue during puberty.

基底膜带
embrane
( besement zone ,BMZ )
表皮与真皮之间分为四个不同的结构区
1)胞膜层(lamina)
2)透明层
( 1amina lucida )
3)致密层(lamina densa) 4)致密下层也称网板(
reticular lamina )
连接区相邻两细胞膜平行,细胞间隙宽约20—30nm。
中央层: 间隙中央电子密度较高的致密层。 间 线:中央层的中间一条更深染的线。 附着板:桥粒的相邻细胞膜内侧各有一个盘状。
29
桥粒构造
由两类蛋白质构成: 跨膜蛋白,位于桥粒芯 (桥粒芯糖蛋白、桥粒芯胶蛋白) 桥粒斑蛋白,附着板的组成成分 (桥粒斑蛋白、桥粒斑珠蛋白)

第一编 总 论
第一节 表 皮(
epidermis
)
表皮 由外胚层 分化而来,属 复
层鳞状上皮,主要由 角质形成细胞( keratinocyte ) 黑素细胞( melanocyte ) 朗格汉斯细胞(1angerhans) 梅克尔细胞(Merkel)
构成。

表 皮 (epidermis)
(一)角质形成细胞
(2)光镜下角质层与颗粒层之间见 2—3层扁平、境界
不清、无核、嗜酸性、紧密相连的细胞。
(3) 胞浆中有较多疏水的蛋白结合磷脂并与张力细
丝融合在一起,有防止水及电解质通过的 屏障作
用。

5.角质层( stratum
corneum
)
(1) 表皮最上层,由 5—20 层 死亡的扁平 、无核的 细胞组成。 (2) 胞内细胞器结构消失。胞浆内充满由张力细 丝和均质状物质结合形成的角蛋白(keratin)。

皮肤护理英文演讲ppt课件
•
Facial Steam • Two to three times a month, after you cleanse and/or exfoliate, treat your skin to a steam bath to deep cleanse the pores and stimulate circulation. People with oily skin can steam more regularly than people with dry or sensitive skin. This should become an important part of your routine if you want beautiful, clear, healthy looking skin.
• •
Moisturize Moisturizing the skin is the final basic step. Use a product containing moisturizing oils, distillates, antioxidants, nutrients and essential oils to prevent moisture loss. Choose a moisturizer that suits your skin type and one that has as many, if not all, natural ingredients as possible. Remember your skin absorbs everything put on it even if it's not natural. • 滋润 • 滋润皮肤是基础护肤的最后一个步骤。推荐使用含有 滋润油、精华素、抗氧化剂、肌肤所需营养以及防止水分 流失成分的产品。同样要选择一款适合自己肌肤的产品, 并尽量使用含有天然元素的。记住你的皮肤会吸收任何涂 抹上的东西,包括那些非天然的元素。

如何解决皮肤暗沉等问题
足部去角质使用方法说明
1.脚步容易堆积大量死皮,趁洗澡之后脚部死皮变软时,多用手指 打圈按摩,可以加强去死皮的效果.
2.想磨砂效果更好而又不想磨损肌肤,平时可以先用浸了热水的 毛巾来包住脚,约5分钟后死皮会软化,去死皮就更容易啦!
3.再用温水冲洗干净即可,可以按摩促吸收,持续使用效果更佳
小贴士:全身去角质时间 每个地方约3-5次,共约15分钟 去 角质次数:2次/1个月
