Everything you need to know about apricot kernel oil.

The apricot oil has an interesting biochemical composition that explains its cosmetic benefits.

Apricot oil can be used in its pure form as a topical application or hair treatment or it can be used to formulate creams, masks, or serums. Its wide range of cosmetic uses is due to its interesting biological activity for the skin and hair.

• Hydrate and soften the skin.

  The numerous fatty acids found in apricot oil enable it to strengthen the skin's lipid barrier. Indeed, some of these fatty acids influence the production of ceramides, molecules found in the intercellular cement of the epidermis that greatly contribute to its flexibility and protection. Additionally, apricot oil contains phytosterols that capture and retain moisture. They support the hydrolipidic film present on the skin's surface and help to limit water loss.

• Protecting the skin from oxidative stress and slowing down skin aging.

  The antioxidants found in apricot oil allow it to neutralize free radicals, which are primarily responsible for the premature degeneration of cells and environmental damage (pollution, sun exposure, tobacco...). This activity helps to prevent skin aging and the pigmentation disorders that oxidative stress can cause. Studies in vitro have also shown that apricot oil can inhibit the activities of collagenase and elastase, enzymes responsible for the degradation of collagen and elastin. Thus, it could protect these essential proteins that maintain skin firmness.

• Alleviate and soothe irritations.

  Apricot oil can also act on certain signs and symptoms of the inflammatory response. Studies have shown that it induces apoptosis in HaCaT cells through certain receptors involved in mitochondrial pathways. This leads to the inhibition of the NF-κB pathway and prevents the synthesis of pro-inflammatory cytokines. The apricot oil is thus a good option for relieving irritations due to minor burns and/or sunburns. It is also credited with the ability to alleviate the symptoms of eczema, although more studies on this subject are still needed.

• Maintaining the quality of hair fibers.

  Apricot oil can also be used to protect and nourish hair fibers. Whether used as a hair oil treatment or incorporated into a hair care product, it makes the hair shiny and soft while preventing the formation of split ends. Similar to its application on the skin, apricot oil strengthens the hydrolipidic film that coats the hair. Additionally, it contributes to the cohesion of the cuticle scales, the outer part of the hair fibers, which provides shine and impermeability to the hair.

Apricot oil is a gentle vegetable oil suitable for application on sensitive skin. However, its use by breastfeeding women or those who have recently given birth should be approached with certain caution. Indeed, it is not recommended to apply apricot oil on the nipples or any body areas that may come into contact with the baby. This precaution is due to the potential traces of amygdalin it may contain: this molecule found in the apricot kernel converts into cyanide upon ingestion, a deadly poison. Similarly, the use of apricot oil on baby's skin is not advised. Instead, opt for calendula oil macerate or camelina oil, which are more suitable.

Furthermore, if you have oily or acne-prone skin, apricot oil may not necessarily suit you as it is slightly comedogenic, meaning it promotes the appearance of comedones in predisposed individuals. If this is your case, it is better to use argan oil, jojoba oil, camellia oil, hazelnut oil, prickly pear oil or avocado oil, all vegetable oils that have a comedogenicity index of 0.

Lastly, remember to check the quality of your apricot oil before using it. Vegetable oils rich in omega-3s are often sensitive to degradation due to the double bonds present in the chemical structure of these compounds. To maintain the quality and safety of your apricot oil, make sure to tightly seal the bottle after each use and store it in a cool place, away from direct sunlight. If in doubt, do not hesitate to perform a tolerance test in the crook of your wrist or elbow to observe any potential skin reactions.
