Why use prickly pear seed oil?

The prickly pear seed oil is prized for its richness in fatty acids, notably linoleic acid, an omega-6 that helps strengthen the skin barrier and limit dehydration. Thanks to its vitamin E content, it also helps neutralise free radicals that accelerate skin ageing. Beyond its nourishing and protective virtues, the prickly pear seed oil stands out for its reparative and soothing potential. Studies have shown that it possesses anti-inflammatory properties, reducing signs of irritation and supporting the healing processes. Prickly pear seed oil also promotes cellular regeneration by stimulating collagen synthesis and improving cutaneous microcirculation.

Prickly pear seed oil is recommended for dry skin, mature or compromised following sun exposure or irritation.

Are there any contraindications to the use of prickly pear seed oil?

Prickly pear seed oil is a versatile plant oil suitable for all the skin types and can be used undiluted.

Indeed, prickly pear seed oil can be used by both dry and oily skin types, as it has a lightweight texture and is non-comedogenic. It also poses no risk during pregnancy : pregnant and/or breastfeeding women can use it to care for their skin, for example to enhance its suppleness with the aim of preventing stretch marks.

Nonetheless, although prickly pear seed oil has few contraindications, certain precautions remain necessary. As a precautionary measure, some healthcare professionals advise against its use in individuals with a known allergy to prickly pears, even if a food allergy does not necessarily result in a cutaneous reaction. If in doubt, do not hesitate to seek advice from your GP. It is also important to recall that prickly pear seed oil is not a tanning oil, contrary to some common misconceptions. When applied prior to sun exposure, it offers no protection against the UV rays.

Prickly pear seed oil: what precautions should be taken?

Prickly pear oil is well tolerated by most skin types but, like any skincare product, it can, in rare cases, cause a skin reaction, such as redness, itching or irritation. To minimise this risk, it is advisable to perform a test the first time you use it: apply a small amount of oil to the hollow of your wrist or the crook of your elbow, then wait for 24 hours. If no reaction occurs within this period, your skin is not sensitive to prickly pear oil and you may begin incorporating it into your skincare routine. This precaution is particularly important for sensitive or reactive skin, although every skin type will benefit from this practice.

Prickly pear seed oil is also highly susceptible to oxidation, which can impair its properties and increase the risk of allergic reactions if it becomes rancid. It should therefore be stored in an airtight amber glass bottle, shielded from air, light and heat. Before each use, it is advisable to check its texture and odour: a quality oil should feel light, absorb rapidly and leave no greasy residue on the skin. If it becomes thick, sticky or emits an unusual odour, it should no longer be used and must be replaced.
