Abstract
The photoprotective skincare products are in high demand to meet the
consumer market with concern on skin health. Seed oils are commonly used
as ingredients in many cosmetic products due to their natural
antioxidants and now being increasingly recognised for their effects on
skin health and photoprotection. This article briefly reviews the
application of seed oils in sunscreen development focusing on the
antioxidants that contribute to photoprotection, thus preventing
UV-induced erythema and photoaging. The addition of seed oils that
contain specific natural bioactive compounds were discussed in the
review. Besides that, seed oils acting in molecular pathways that
benefit in photoprotection were also summarized. Seed oils (pomegranate
seed oil, castor oil, cocoa butter, jojoba oil, rosehip oil, grapeseed
oil, kenaf seed oil and pumpkin seed oil) utilization have high
potential to act as natural UV filters and at the same time help in skin
repairing. The seed oils contributed beneficial properties to the
sunscreen formulation by their synergistic effect with antioxidants,
antiaging properties, anti-inflammatory effect, and potential hormetic
effect. The finding of specific bioactive compound from seed oils
provide better understanding on the contribution of seed oils in
sunscreen formulation.
