The science
Two things are worth knowing about this product's science, and they pull in opposite directions. The first is that oil cleansing is genuinely the best way to get sunscreen off. A 2020 study in the Journal of Cosmetic Dermatology photographed twenty volunteers with VISIA imaging after applying non-waterproof and waterproof sunscreens and then washing with water alone, a foaming cleanser or a cleansing oil. For the waterproof sunscreen, water left 59 percent of the product behind and the foaming cleanser 37 percent, while the cleansing oil left under 6 percent — statistically indistinguishable from clean skin — and the oil group reported less post-wash dryness. That is the mechanism this Goodal formula relies on: a corn germ oil and light-ester base that dissolves lipophilic UV filters, and a sorbeth-30 tetraoleate emulsifier that lets the loaded oil rinse away as a milk. Nothing in the fifty other ingredients improves on that basic chemistry, and nothing needs to.
The second is that essential oils are not a neutral addition. A 2021 review in the International Journal of Women's Dermatology summarised the growing case literature on allergic contact dermatitis from essential oils, noting that their composition is more complex than assumed and that clinicians evaluating suspected contact dermatitis should now ask about them routinely. This oil carries nine: fir, rosemary, clary sage, geranium, clove leaf, patchouli, German and Roman chamomile and juniper. Clove contributes eugenol and geranium contributes geraniol and citronellol — all regulated fragrance allergens — while the conifer and herb oils contribute limonene, linalool and pinene, terpenes that oxidise in an open bottle into more potent sensitizers. Rinse-off exposure is shorter and lower-risk than leave-on, which is why most users will never react, but it does not make a sensitised person safe.
The ingredients the marketing leads with — ten hyaluronate species, five ceramides with cholesterol, panthenol, succinic acid — are all listed after water and are disclosed by the brand at parts-per-million levels. Even if they were dosed generously, the contact time of a first cleanse is too short and the rinse too complete for humectants or barrier lipids to deposit meaningfully. The heartleaf extract that names the product sits twelfth, behind the emulsifiers and fruit extracts and ahead of the essential oils; its anti-inflammatory record in laboratory studies is modest and irrelevant to a rinse-off. The formula's real evidence base is the emulsifying oil cleanser itself, which is solid, and its real risk is the fragrance load, which is real.
