Prunus Cerasus (Bitter Cherry) Seed Oil is a plant-derived lipid obtained by cold-pressing the seeds of Prunus cerasus, a species within the Rosaceae family. From a cosmetic formulation perspective, this oil is characterized by a high content of unsaturated fatty acids, particularly oleic acid (omega-9) and linoleic acid (omega-6), along with smaller fractions of palmitic and stearic acids. This lipid profile contributes to its ability to reinforce the stratum corneum lipid matrix, reducing transepidermal water loss (TEWL) and improving skin flexibility. In addition, Bitter Cherry Seed Oil naturally contains tocopherols and phenolic compounds, which provide antioxidant activity capable of mitigating oxidative stress induced by UV radiation and environmental pollutants. These properties make it suitable for formulations targeting skin barrier recovery, dehydration, and premature aging.

In haircare applications, Prunus Cerasus Seed Oil functions primarily as a lightweight emollient and conditioning oil. Its relatively low viscosity and favorable spreadability allow it to coat the hair fiber evenly without excessive buildup, improving cuticle smoothness, shine, and mechanical resistance. The presence of linoleic acid supports scalp barrier integrity, which can be beneficial in formulations aimed at dry, sensitive, or stressed scalps. When incorporated into conditioners, masks, or leave-in treatments, Bitter Cherry Seed Oil contributes to improved combability, reduced frictional damage, and enhanced hair softness, while maintaining a non-occlusive sensory profile suitable for fine to medium hair types.
