For the assessment, a prospective randomized controlled study was conducted on postmenopausal women with Fitzpatrick skin types I or II. One group of women consumed 20% of their daily energy from almonds and the control group consumed a snack with the same number of calories. To analyze the photoaging effects of almonds, a facial photograph and image analysis system was used to provide high-detailed information on facial wrinkle width and severity at 0, 8, 16, and 24 weeks. The aforementioned indicators of skin were also analyzed at each point.
Researchers found that the average wrinkle severity and the facial pigment intensity were both significantly decreased starting at week 16 and continuing through to week 24. The group that consumed almonds saw wrinkle severity drop 15% at week 16 and 16% by week 24. The facial pigment intensity dropped 20% at week 16 and was constant through week 24. All other indicators lacked significant changes. In conclusion, consuming almonds may lead to the improvement of facial wrinkles and facial pigmentation for postmenopausal women with Fitzpatrick skin types I and II.
