Ingredients Explained
This oil comes from the shea tree.
It has emollient properties - meaning when applied, it creates a thin film to trap moisture within. This helps keep your skin smooth and hydrated.
Lavandula Angustifolia Extract comes from the lavender flower. It's also known as English Lavender and is famous for creating purple fields in Provence, France.
This ingredient anti-inflammatory properties due to its prostanoids and histamine content. Lavender also contains flavonoids and phenolic acids (such as ferulic acid), potent antioxidants.
Lavender extract may have a scent. It contains linalool, a known allergen. However, lavender extract contains less linalool than lavender essential oil.

Rosehip seed oil is one of the more polyunsaturated plant oils in cosmetics; it's loaded with fatty acids like linoleic acid (~44%), alpha-linoleic acid (~34%), and oleic acid (~14).
Another interesting compound that makes it stand out from other oils is the trace amount of all-trans retinoic acid (the same molecule as prescription tretinoin), along with some carotenoids and tocopherols.
The linoleic acid is a precursor to ceramide 1, one of the essential lipids in the stratum corneum. Topical linoleic acid application has been shown to improve barrier function and reduce comedone size in clinical studies.
One study found that linoleic acid and alpha-linoleic acid lighten UV-induced hyperpigmentation. A 2015 study found that participants who used rosehip twice daily for eight weeks saw improvements in crow's feet, skin moisture, and skin elasticity compared to the placebo.
If you're hoping to get tretinoin benefits from this ingredient, it's worth noting the trans-retinoid acid is trace-level and minimal compared to the amount of retinol or tretinoin found in formulas.
A 2024 review highlighted the fatty acid composition in rosehip-based dermatological products for:
Typical usage rates range from 1-100% with 5-10% being the most common in moisturizers.
Since the oil is high in polyunsaturated fatty acids, it's prone to oxidation. Look for formulations stabilized with ingredients like vitamin E and be sure to store away from light/heat.
Fungal acne: This oil is not considered fungal acne safe because dominant fatty acids fall into the C11-24 range that Malassezia can metabolize.

You'll find this ingredient in the vast majority of skincare (for good reason). It works to neutralize free radicals, or unstable molecules generated by UV exposure, pollution, and other environmental stressors, before they can cause oxidative damage to your skin cells.
Topically applied tocopherol has been shown to protect against UV damage by ramping up the skin's own natural defense enzymes.
It also acts as a skin conditioning agent; some studies show that regular topical use can improve the skin's water-binding capacity over 2-4 weeks.
This ingredient is especially loved for being a team player. When combined with Vitamin C, the photoprotective effect of both ingredients roughly doubles and the combo also helps reduce UV-induced DNA damage.
This ingredient has some brightening potential but it's more of a prevention ingredient than spot-fader. Cell studies show it can slow down melanin production but it's worth noting that it's not the most powerful brightener out there.
In formulations, it also serves as a stabilizer that helps protect other oxidation-prone ingredients from degrading.
Concentrations usually range from 0.1-1% in most leave-on products.
