To determine the respective weights of certain facial signs on the assessment of perceived age and plumpness on Korean women of different ages.
Photographs were taken of the faces of 112 Korean women of different ages (18-80 years) under standardized conditions. These photographs allowed to focus and define 19 facial signs, which were then graded by 15 experts and dermatologists, using standardized scales provided by a reference Skin Aging Atlas. The facial signs were dispatched into 5 clusters, namely Wrinkles/Texture, Ptosis/Sagging, Pigmentation disorders, Vascular disorders, and Cheek skin pores. A naïve panel, composed of 92 Korean women, of similar age range were asked, when viewing full-face photographs, to: (a) attribute on a 0-10 scale their perception of the skin plumpness (ie supple/hydrated/nourished) and (b) estimate the age of the subject.
With the exception of Vascular disorders, the severity of all 4 clusters increased with age, although at different rates. The Wrinkles/Texture or Ptosis/Sagging showed a rather regular progression. Although perceived ages and real ages were found highly correlated, half of the subjects were judged older by 2-12 years. The facial signs/clusters were significantly correlated with perceived age, with the exceptions of vascular disorders, size of pigmentary spots and cheek skin pores. The weights in perceived ages of Wrinkles/Texture and Ptosis/Sagging represent 37% each and Pigmentation disorders at 26%. Skin plumpness was logically found significantly anti-correlated with perceived age. If, surprisingly, Vascular disorders were found not impacting the plumpness aspect, Cheek skin pores presented a clear influence.
Within facial clinical clusters, Wrinkles/Texture, Ptosis/Sagging, and Pigmentation disorders are major factors in the assessment of perceived age in Korean women. The perception of a decreased skin plumpness is significantly associated with increased perceived age.
确定某些面部特征在评估不同年龄韩国女性的感知年龄和丰满度方面各自的权重。
在标准化条件下,对112名不同年龄(18 - 80岁)的韩国女性面部进行拍照。这些照片有助于聚焦和界定19种面部特征,然后由15名专家和皮肤科医生使用参考皮肤老化图谱提供的标准化量表对其进行分级。面部特征被分为5组,即皱纹/纹理、上睑下垂/松弛、色素沉着紊乱、血管紊乱和脸颊皮肤毛孔。一个由92名年龄范围相似的韩国女性组成的普通小组,在观看全脸照片时被要求:(a)在0 - 10分的量表上对她们对皮肤丰满度(即柔软/水润/有营养)的感知进行评分,以及(b)估计受试者的年龄。
除血管紊乱外,所有4组的严重程度均随年龄增长,尽管速度不同。皱纹/纹理或上睑下垂/松弛呈现出较为规律的进展。虽然发现感知年龄与实际年龄高度相关,但一半的受试者被判定年龄比实际年龄大2 - 12岁。面部特征/组与感知年龄显著相关,但血管紊乱、色素沉着斑大小和脸颊皮肤毛孔除外。皱纹/纹理和上睑下垂/松弛在感知年龄中的权重各占37%,色素沉着紊乱占26%。逻辑上发现皮肤丰满度与感知年龄呈显著负相关。令人惊讶的是,虽然发现血管紊乱不影响丰满度方面,但脸颊皮肤毛孔有明显影响。
在面部临床分组中,皱纹/纹理、上睑下垂/松弛和色素沉着紊乱是评估韩国女性感知年龄的主要因素。皮肤丰满度下降的感知与感知年龄增加显著相关。
