Aloe vera, the natural remedy against eczema.

Aloe vera is a plant from the Asphodelaceae family. It is easily recognisable by its thick and fleshy leaves, reminiscent of the structure of a lotus flower. The aesthetics of aloe vera make it a popular indoor plant among decoration enthusiasts. However, this plant is not only beautiful, it is also beneficial for skin suffering from eczema due to its numerous properties.

• Aloe vera gel is hydrating. This characteristic stems from its composition. Rich in amino acids and hygroscopic polysaccharides, it moisturises the epidermis and leaves no oily film on the skin's surface. The skin prone to atopy particularly requires good hydration due to the fragility of their hydrolipidic film.

• Aloe vera gel is also healing. The acemannan molecule, found in aloe vera gel, stimulates the production of collagen and glycosaminoglycans. These extracellular matrix compounds contribute to maintaining the structure of the skin. Moreover, the glucomannan also present in this gel acts on the fibroblast growth factor, TGF-β1, thereby increasing their activity. The secretion of elastin and collagen by the fibroblasts is thus amplified. Topical application of aloe vera gel on skin suffering from eczema can therefore help to reduce the presence of lesions and red patches.

• The anti-inflammatory action of this botanical extract also allows it to alleviate redness and itching caused by eczema. Aloe vera gel soothes the skin by limiting the production of pro-inflammatory cytokines such as TNF-α and interleukin 6. TNF-α is targeted by certain flavonoids (quercetin and kaempferol) contained in aloe vera gel and its activity is inhibited.

The topical application of aloe vera gel on red patches is thus a way to alleviate an eczema flare-up. Moreover, the gel derived from this plant provides a feeling of freshness, soothing itchiness and irritations.

Please note : while aloe vera gel can help to soothe the symptoms of eczema, it is not a miracle cure and will not be able to heal it.

This ingredient is suitable for sensitive skin and its topical application does not presumably have any contraindications. However, it may be prudent to perform a tolerance test before using it regularly on atopic skin. To do this, apply a few drops in the crook of your elbow or behind the ear, and wait 24 hours. If no adverse reaction is observed, you can use it to combat eczema.

However, it is important to note that the studies referenced were not conducted on individuals suffering from eczema, but on skin with various wounds and injuries. Therefore, the properties of aloe vera gel presented here have not been directly demonstrated to alleviate eczema.
