CITRUS GRANDIS PEEL OIL, derived from grapefruit peel, is a multifaceted ingredient known for its aromatic properties and significant skin benefits.

Science

Mechanism of Action

This ingredient functions as an antimicrobial agent, protecting the skin barrier from bacterial and fungal proliferation, which is particularly beneficial for acne-prone skin. Rich in Vitamin C, it serves as a potent antioxidant, neutralizing free radicals to mitigate premature skin aging. Its sebum-balancing and astringent properties help regulate oil production and visibly tighten pores. Furthermore, the presence of alpha hydroxy acids (AHAs) and natural enzymes facilitates gentle exfoliation and cell renewal, contributing to a smoother, more radiant complexion, reduction in hyperpigmentation, and support for collagen synthesis, promoting firmer-looking skin.

Sensitization risk Moderate

Finished products (excluding rinse-off formulations) must not exceed 0.0015% (15 ppm) 5-methoxypsoralen (5-MOP) due to photosensitivity concerns. The presence of furanocoumarins may increase sensitivity to sunlight, elevating the risk of sunburn or irritation; evening application is highly recommended, or rigorous sun protection during the day. Individuals with sensitive skin or known citrus allergies may experience adverse reactions such as redness, itching, or irritation, necessitating a prior patch test.
