The Antera 3D demonstrated its relevance for cosmetic product evaluation. We also provide recommendations for the analysis based on our findings.

Pore measurements with the Antera 3D represent a reliable tool for efficacy and field studies, with an emphasis of the small filter for analysis for the mean pore volume/mean pore area parameters.

Background The use of a skin care routine is commonly promoted by the cosmetic industry, yet there is a lack of clinical evidence to support this practice over the use of a single skin care product. Aims In the present study, we aimed at showing the clinical benefits of using a comprehensive skin care routine vs a simple one. Methods Skin micro‐/macro‐topographic, skin color, and superficial/deep hydration were collected at baseline and after 4 weeks of use, on forty‐nine women randomly allocated to two groups. The first one followed the use of an advanced routine (AR: Cleanser/Toner/Eye cream/Serum/Day & Night cream), while the other group was instructed to use a simple routine (SR: Cleanser & Day cream). Results Hemoglobin heterogeneity was found to be significantly reduced only in the SR group. However, the AR outperformed the SR when it comes to improving superficial hydration, deep hydration, skin roughness, mean pore area, melanin heterogeneity, and crow's feet wrinkle depth. A significant increase in skin brightness from baseline was only recorded when using the AR while both routines significantly improved the nasolabial wrinkles. Conclusion These findings advocate for using a relevant daily routine as it demonstrates the visible skin benefits over a short period, while driving the creation of habits for the prevention of aging signs.

Background As the eye contour ages, the skin on the lid becomes lax often causing a voluminous protrusion where the superior palpebral sulcus begins to sag onto the upper eyelid. This sagging feature may present a novel anti‐ageing target for cosmetic products when treating the eye area. A quantitative method to evaluate the volume of this sagging feature has not been previously established. We investigate the use of the DermaTOP fringe projector and Antera 3D Camera to this end. Methods Eyelid topographic measurements were collected on 20 female volunteers aged 50‐75 years with the DermaTOP and Antera 3D. The DermaTOP and Antera 3D measurements were assessed for reproducibility and product effect detection capabilities. Results The DermaTOP and Antera 3D successfully measured sagging feature volume, demonstrated reproducibility of measurement and furthermore were suitably sensitive to allow for detection of sagging feature volume reduction after a single application of aqueous tightening serum. DermaTOP parameters were found to moderately correlated with the Antera 3D parameters. Conclusion Both the DermaTOP and Antera 3D allow for quantitative measurement of eyelid sagging feature volume and in‐turn permit evaluation of anti‐ageing cosmetic preparations targeting the eyelid.

Background & Aims Previous investigations have aimed at investigating parameters affecting age perception on several ethnicities. Perceived health has been a newer focus on Caucasian skin, yet little is known on the skin features used to estimate the health status of Chinese women and we aimed to investigate whether these cues are the same as those used for age perception. Methods Age and health appearance of 276 Chinese female volunteers were estimated from their photographs by 1025 female naïve Chinese graders 20–69 years old. Models were built to predict perceived age and health from topographic, colour and biophysical measured variables, in two subsets of the studied volunteers: below and above 50 years. Machine learning‐based predictive models for age and health perception were built on the collected data, and the interpretability of the models was established by measuring feature importance. Results Age perception was mostly driven by topographic features, particularly eye bags and eyelid sagging in the group below 50 years old. Wrinkles, notably from the lower part of the face and oval of the lower face, were found to be more relevant in the group above 50 years. Health appearance was primarily signalled by skin imperfections and global pigmentation in the subset below 50 years, whereas colour‐related parameters and skin hydration acted as health cues for the subset above 50 years. Conclusion Distinct skin features were acting as cues for age perception and/or health perception and varied per age subset. Their contribution should be borne in mind when designing products for ‘younger looking skin’ and ‘healthier looking skin’.
