“…Similar to other molecular components of the extracellular matrix such as collagen, fibrillin, fibulin, fibrinogen, fibronectin, laminin, tenascin and thrombospondin, elastin is a protein that is present in several connective tissues and confers a unique physiological elasticity [33][34][35][36]. Synthesized by fibroblasts and keratinocytes, elastin provides support to the blood vessels, lungs and skin [30,37,38].…”

Skin aging is a complex process that may be caused by factors that are intrinsic and extrinsic to the body. Ultraviolet (UV) radiation represents one of the main sources of skin damage over the years and characterizes a process known as photoaging. Among the changes that affect cutaneous tissue with age, the loss of elastic properties caused by changes in elastin production, increased degradation and/or processing produces a substantial impact on tissue esthetics and health. The occurrence of solar elastosis is one of the main markers of cutaneous photoaging and is characterized by disorganized and non-functional deposition of elastic fibers. The occurrence of UV radiation-induced alternative splicing of the elastin gene, which leads to inadequate synthesis of the proteins required for the correct assembly of elastic fibers, is a potential explanation for this phenomenon. Innovative studies have been fundamental for the elucidation of rarely explored photoaging mechanisms and have enabled the identification of effective therapeutic alternatives such as cosmetic products. This review addresses cutaneous photoaging and the changes that affect elastin in this process.R esum e Le vieillissement de la peau est un processus complexe qui peutêtre caus e par des facteurs intrins eques et extrins eques du corps. Les rayons ultraviolets (UV) repr esentent l'une des principales sources de dommages de la peau au fil des ans et caract erise un processus connu sous le nom de photo-vieillissement. Parmi les changements qui affectent le tissu cutan e avec l'âge, la perte des propri et es elastiques caus ees par des changements dans la production d' elastine, augmentation de la d egradation et / ou le traitement, produit un impact important sur l'esth etique et la sant e des tissus. La survenue d'une elastose solaire est l'un des principaux marqueurs de photo-vieillissement cutan e et se caract erise par un d epôt d esordonn e et non-fonctionnel des fibres elastiques. L'apparition d'un epissage alternatif du g ene de l' elastine induit par le rayonnement UV, ce qui conduit a une synth ese insuffisante des prot eines n ecessaires a l'assemblage correct des fibres elastiques, est une explication possible de ce ph enom ene.

Cette revue porte sur le photo-vieillissement cutan e et les changements qui affectent l' elastine dans ce processus.

Background/Aims: Our previous study confirmed that Aloe sterol stimulates collagen and hyaluronic acid production in human dermal fibroblasts. This study aims to investigate whether Aloe sterol intake affects skin conditions. Methods: We performed a 12-week, randomized, double-blind, placebo-controlled study to evaluate the effects of oral Aloe sterol supplementation on skin elasticity, hydration, and the collagen score in 64 healthy women (age range 30-59 years; average 44.3 years) who were randomly assigned to receive either a placebo or an Aloe sterol-supplemented yogurt. Skin parameters were measured and ultrasound analysis of the forearm was performed. Results: ANCOVA revealed statistical differences in skin moisture, transepidermal water loss, skin elasticity, and collagen score between the Aloe sterol and placebo groups. The gross elasticity (R2), net elasticity (R5), and biological elasticity (R7) scores of the Aloe sterol group significantly increased with time. In addition, skin fatigue area F3, which is known to decrease with age and fatigue, also increased with Aloe sterol intake. Ultrasound echogenicity revealed that the collagen content in the dermis increased with Aloe sterol intake. Conclusion: The results suggest that continued Aloe sterol ingestion contributes to maintaining healthy skin.

“…Skin aging is associated with a progressive increase in extensibility and a reduction in elasticity. With increasing age, the skin also becomes more fragile and susceptible to trauma, and this leads to more lacerations and bruising [3].…”
