System Verdict
This is a straightforward cleansing oil with a decent solvent-emollient base, but it is not a treatment product and the fragrance plus Isopropyl Myristate keep it from being exceptional. The efficacy score is driven by its ability to dissolve makeup, sunscreen, and excess sebum through a high-oil, ester-rich formula with emulsifiers that should rinse cleanly; it is not boosted by vitamin E because that is a minor support ingredient in a rinse-off cleanser, and the added fragrance slightly lowers the safety score.
