Key ingredients

Ricinus Communis (Castor) Seed Oil
Castor oil, derived from Ricinus communis seeds, is an occlusive ingredient rich in unsaturated fatty acids, with about 90% being ricinoleic acid, which provides potent anti-inflammatory and soothing effects. It also contains oleic, linoleic, and palmitic acids, contributing to its emollient, moisturizing, and mildly comedogenic properties. Castor oil has antioxidant and antimicrobial abilities, making it popular in acne treatments, though its mild comedogenicity may clog pores if not used properly in your skin care routine. It can increase the penetration of other skin care ingredients in the skin care routine.

Helianthus Annuus (sunflower) Sprout Extract
Helianthus Annuus (Sunflower) Sprout Extract boosts cellular energy with ATP, defends against oxidative stress, and reduces glycation damage. Rich in antioxidants and omega-3s, it enhances firmness, smooths texture, and strengthens the skin barrier for visibly healthier, more resilient skin.
