Shedding Light on the Effects of Calorie Restriction and Its Mimetics on Skin Biology
May 2020
in “Nutrients”
TLDR Eating fewer calories may slow skin aging and improve skin health through various biological changes.
The document from May 2020 discussed the effects of calorie restriction and its mimetics on skin biology. It revealed that calorie restriction can promote structural and metabolic changes in the skin, potentially slowing the aging process. The role of sirtuins, specifically SIRT1, in regulating inflammation, cell migration, and wound healing in the skin was highlighted. The compound resveratrol, known to activate SIRT1, was discussed for its potential in skin care applications, including antioxidant properties, skin lightening efficacy, and potential in melanoma chemoprevention. The document also mentioned the use of nanocarriers for targeted topical skin delivery of resveratrol. The role of metformin in promoting lifespan and healthspan in various organisms by altering microbial folate and methionine metabolism was discussed, as well as its potential in alleviating endotoxemia-induced acute lung injury and inducing a dietary restriction-like state. The role of mTOR in skin aging and psoriasis, and the potential of rapamycin, an mTOR inhibitor, in reducing markers of senescence and aging in human skin were also discussed. Lastly, the role of peroxisome proliferator-activated receptors (PPARs) in skin biology and pathology, and their potential modulation by calorie restriction were discussed.

Aging in hair follicle stem cells leads to hair graying, thinning, and loss.
research Beyond acne: Current aspects of sebaceous gland biology and function
The sebaceous gland has more roles than just producing sebum and contributing to acne, and new research could lead to better skin disease treatments.
research Hair follicle aging is driven by transepidermal elimination of stem cells via COL17A1 proteolysis

research Regenerative Hair Waves in Aging Mice and Extra-Follicular Modulators Follistatin, Dkk1, and Sfrp4
Aging mice have slower hair regeneration due to changes in signal balance, but the environment, not stem cell loss, controls this, suggesting treatments could focus on environmental factors.
research Emerging interactions between skin stem cells and their niches
Skin stem cells interacting with their environment is crucial for maintaining and regenerating skin and hair, and understanding this can help develop new treatments for skin and hair disorders.

research How real is senescent alopecia? A histopathologic approach
Aging alone rarely causes significant hair loss; hormones are a bigger factor.
research The lack of significant changes in scalp hair follicle density with advancing age
Aging alone barely affects the number of hair follicles, meaning hair loss is minimal without other conditions like androgenetic alopecia.
