Psoriasis: How to exfoliate your skin?

The psoriasis is a chronic inflammatory disease that primarily manifests in the skin and joints. It presents as red, thick plaques that shed. Psoriasis is characterised by an excessive renewal and accumulation of epidermal cells, leading to a local inflammation. About 30% of psoriasis cases are considered familial forms that manifest in adolescence. If psoriasis develops after the age of 40, it is referred to as isolated or sporadic forms. It is important to note that psoriasis affects both sexes equally.

Histological analyses reveal an increase in the thickness of the epidermis (acanthosis) and incomplete differentiation of keratinocytes (parakeratosis). Psoriasis is triggered by a combination of risk factors including the immune system, genetic predisposition, and environmental factors.

Exfoliation can be beneficial for individuals affected by psoriasis. Indeed, it aids in the removal of dead cells and reduces the patches of scales found on the skin. As psoriasis causes itching and skin irritation, it is crucial to exfoliate the skin gently. Indeed, in the case of psoriasis, it is not recommended to scratch the skin, because the epidermis perceives scratching as an attack, which leads to an overproduction of scales and patches, exacerbating the flare-up. Therefore, exfoliation must be carried out gently.

For this, you can use a loofah which is a natural sponge derived from the fibres of the fruit of the Luffa aegyptiaca, a climbing plant from the cucumber family. Resembling a courgette or cucumber, this fruit is harvested when ripe and then dried. Its skin and seeds are removed, leaving only the fibres. The result: a plant-based sponge that can be used like a washcloth. The loofah is ideal for gently exfoliating the skin. It should be moistened and your shower gel or soap, preferably of neutral pH, applied before rubbing it on your skin. Pat to create a lather and make circular movements during cleansing to exfoliate psoriasis.

Be gentle in your movements to remove dead skin cells. Indeed, vigorous exfoliation can make the skin more sensitive and may risk drying it out. During cleansing, you'll know you're applying the right level of pressure if you don't feel as though you're being scratched.

After each exfoliation, remember to moisturise your skin. In case of psoriasis, opt for a skin care treatment with soothing and repairing action to alleviate itching.

Furthermore, it is important to avoid excessively hot water, as it can be harsh on the skin. A shower with lukewarm water is preferable. Regarding drying, vigorous actions should also be avoided, as the epidermis perceives them as an assault and will react accordingly. Pat dry instead.
