Background: Facial skin redness can have a negative impact on the quality of life. In this study, we investigated the skin biophysical parameters associated with facial skin redness as a function of aging.

Methods: Our aims were as follows: (1) to understand the impact of non-pathological facial skin redness on the quality of life of Korean women through a survey; and (2) compare skin biophysical properties between women with and without facial skin redness.

Results: Women aged between 20 and 39 years perceived their own facial skin redness at a higher rate than those aged ≥40 years. In addition, in redness-prone women, the intensity of skin redness and skin surface perfusion were higher, while skin hydration was lower regardless of age. In redness-prone women aged ≥40 years, the values for transepidermal water loss, elasticity, and skin thickness were lower, and the mean pore depth was greater. Facial redness intensity was higher, and the distribution was wider in redness-prone younger women, while only redness intensity increased in the older age group.

Conclusions: Overall, redness-prone women aged ≥40 years had weaker skin properties. Our study indicated the age-related biophysical characteristics of non-pathological facial skin redness. We believe that our findings will help improve its negative effects.

The effect of Baby-Friendly Hospital Initiative compliance on the association between mode of birth and breastfeeding initiation in Sri Lanka.

BMC Pregnancy Childbirth

Background: In Sri Lanka, there is some evidence that the likelihood of breastfeeding initiation varies by exposure to Baby-Friendly Hospital Initiative [BFHI]-compliant care and mode of birth. Globally, there is some evidence that exposure to mother-baby skin-to-skin contact (BFHI Step 4) is lower in caesarean section births. Therefore, we aimed to determine how breastfeeding initiation varies by mode of birth in Sri Lanka, and the extent to which women's exposure to BFHI practices explains any associations found.

Characterizing biomarkers of ageing in Singaporeans: the ABIOS observational study protocol.

Ageing is the primary driver of age-associated chronic diseases and conditions. Asian populations have traditionally been underrepresented in studies understanding age-related diseases. Thus, the Ageing BIOmarker Study in Singaporeans (ABIOS) aims to characterise biomarkers of ageing in Singaporeans, exploring associations between molecular, physiological, and digital biomarkers of ageing.

The demand for aesthetic surgery continues to increase, and it is therefore essential to ensure that the next generation of plastic surgeons are adequately trained. We propose a safe method in aesthetic training in abdominoplasty and facelift, utilizing free deep inferior epigastric perforator (DIEP) flap and parotidectomy for training aesthetic procedures. The trainees' focus differed between the 2 procedures.
