Dry Feet: What are the Causes?

The skin on the feet is similar to that of the hands and does not contain sebaceous glands, which are responsible for the production of sebum. This substance contributes to the hydration and protection of the skin and scalp against external aggressions. The absence of sebaceous glands on the feet thus makes it a vulnerable area, prone to dryness. This is due to a water imbalance between the different layers of the skin. The evaporation of water from the skin's surface is faster than its transfer between the dermis and the epidermis.

There are several causes of dry feet. They can occur due to a lack of hydration. For instance, a day at the beach combining water, sand, and salt can amplify this phenomenon. This is also the case with the use of certain degreasing soaps. Excessive sweating, caused by certain synthetic materials, can also promote foot dryness.

Furthermore, wearing ill-fitting shoes (too narrow, high heels, etc.) subjects the skin to a great deal of friction. In defense, the skin will thicken and harden. This hyperkeratosis contributes to the drying of the feet. Lastly, temperature fluctuations can cause skin dehydration. As the cold approaches, the blood vessels that supply the skin contract, leading to a decrease in nutrient supply. The sebum production by the sebaceous glands drops, which promotes skin dryness.

To prevent this, it is recommended to regularly hydrate them. Dry feet can cause heel cracking, which can lead to the formation of fissures. When these reach the dermis, they can cause bleeding and pain.

Does aloe vera work on dry feet?

A dry foot suffers from skin dehydration. The application of aloe vera gel, with its moisturizing and soothing properties, can mitigate this phenomenon. The presence of hygroscopic compounds in aloe vera gel allows it to limit the evaporation of water on the skin's surface, so that the skin remains supple and elastic. Suitable for all skin types, it leaves no residue after use.

Furthermore, its healing and regenerative properties promote the disappearance of cracks present on the heel of a dry foot. A recent study indeed showed that acemannan, a polysaccharide found in aloe vera gel, accelerates wound closure by activating the ATK/mTOR signaling pathway, which is notably involved in the development of new capillary vessels (angiogenesis). In addition, aloe vera gel also contains glucomannan, another polysaccharide essential for healing. This molecule acts on the fibroblast growth factor, TGF-β1, thereby increasing their activity. The secretion of elastin and collagen is thus amplified.

Dry feet: what is the right approach?

Therefore, to combat dry feet, it is possible to apply a moisturizing treatment based on aloe vera. We have developed a gelified liquid galenic formulation containing this ingredient and fulfilling this function.

Enriched with aloe vera (INCI name: Aloe Barbadensis Leaf Juice) and orange blossom hydrosol (INCI name: Citrus Aurantium Amara Flower Extract), our hydrating gel reduces the feelings of tightness characteristic of dry skin and hydrates it, leaving a sensation of freshness.
