Mecca Cosmetica Everyday Face Oil

Unlike other plant oils, jojoba wax doesn't easily penetrate skin. It mostly works in the uppermost layers as an emollient. This just means it forms a light barrier on the skin to help retain moisture.

Formulations with jojoba esters up to 90% reduced transepidermal water loss (TEWL) and increased barrier recovery by 81% (outperforming bisabolol at 47%).

Besides barrier support, the science also suggests jojoba to have anti-inflammatory effects and potential applications for skin infections, aging, and wound healing.

Fun fact: Indigenous cultures have used jojoba as a moisturizer and to help treat burns for centuries.

Fungal acne: The Malassezia yeast is known to metabolize fatty acids in the C11-24 range and jojoba's dominant fatty acid components fall into this range. This ingredient may not be fungal acne safe.

Two clinical studies in postmenopausal women found that applying argan oil for 60 days significantly improved skin elasticity and moisturization (reduced transepidermal water loss and increased epidermal water content).

Since it is high in oleic and linoleic acid, this ingredient may not be fungal acne safe. Both of these fall in the C11-C24 range that Malassezia yeast can metabolize.

This ingredient may help soothe your skin by reducing inflammation. Emerging studies show it inhibits nitrous oxide production safely, therefore reducing inflammation.

Marigolds have been used in traditional medicine throughout Asia and Europe.

This oil is rich in fatty acids, including: two types of linoleic acid (~30-34%), oleic acid (17%), and palmiteic acid (35%). Note these numbers are averages, and different parts of the plant will vary.

Palmitoleic acid has been shown to help soothe inflammation and promote wound healing. It is also naturally found in the fat of our skin.

Overall, seabuckthorn oil is great for nourishing, hydrating, and soothing skin. While it shows UV protecting properties, it should not replace sunscreen.

Due to the rich fatty acid content, this ingredient may not be Malassezia folliculitis, or fungal acne, safe.

Seabuckthorn berries are little orange fruits. This plant is native to Asia.

Rosa Damascena Extract is a tonic. Tonics are used to remove soap residues. They also help moisturize the skin.

This ingredient is not known to sensitize or irritate skin (unlike Vanilla Tahitensis). Vanilla tahitensis has shown to irritate skin in low amounts.

In cosmetics, its job is mostly sensory: it has a sweet, floral scent often used in perfume.

Chemically, it's complex mix of fragrant molecules: geraniol, limonene, linalool and benzyl benzoate.

Several of these components are on the EU's list of recognized fragrance allergens; this means they have to be labeled when present above 0.001% in leave-on products and 0.01% in rinse-off products.

This ingredient is a known contact sensitizer for a small amount of people so it's definitely worth patch-testing if your skin is reactive.

Lab studies have found the oils does have real antioxidant and antibacterial activity, but keep in mind these are in-vitro findings rather than proven skincare benefits.
