What are the side effects of shea butter?
Moisturising, regenerating, softening, and antioxidant, the shea butter nourishes the skin and hair fibres. Indeed, it deeply hydrates the skin and strengthens the skin barrier against external aggressions. Therefore, it is an ally for dry, mature, and atopic-prone skin. It is also present in various types of treatments, whether in the form of lotion, cream, or mask.
There are no knowndangers associated withthe normal cosmetic use of shea butter. It can be used by pregnant women and young children. It is considered by the international committee of experts as a safe cosmetic ingredient that can be usedup to a concentration of 60% in the finished product, without any particular toxic risk.
Despite its numerous virtues, shea butter contains an allergenic agent: latex. This substance can cause adverse effects in individuals suffering from skin and respiratory allergies. The effects can vary depending on the degree of tolerance, the amount applied, and the duration of application. Often, latex intolerance presents as skin irritation, leading to the appearance of redness, swelling, or itching. In cases of severe intolerance, the topical use of a product containing latex can cause contact dermatitis.
What precautions should be taken?
It should be noted that there is currently no treatment to eradicate allergies. In the event of adverse effects, stop using the product and rinse thoroughly with water. To determine whether you are tolerant to shea butter or not, apply a small amount of the product in the crook of your elbow 48 hours in advance. If you notice irritations, tingling or itching, this means that you are not tolerating the product well. Otherwise, it is always necessary to follow the instructions provided by the manufacturer to avoid adverse reactions.
Furthermore, it is advisable to favour pure shea butter over refined, given that this process utilises substances that can irritate the skin. Refining can also alter the constituents of shea butter and affect its benefits. Additionally, shea butter protects you against UV rays, but does not replace the action of sun creams. Therefore, apply an SPF30 type sun cream for any prolonged exposure to the sun.
Ingredients not to be combined with shea butter.
Even though the shea butter is non-comedogenic, it remains oily. Combining shea butter with a comedogenic oil should be avoided, as it risks clogging the pores. This is particularly the case with the coconut oil and wheat germ oil.
