For your skin
A wax film former that quietly does what petrolatum does (slows water loss and shields chapped skin) without feeling slick. Most evidence comes from honey/beeswax/olive-oil cerates that beat vehicle in eczema and psoriasis trials. CIR-affirmed safe.

Long-chain fatty-acid ester wax (palmitate, palmitoleate, oleate esters of C30-C32 alcohols) that forms a semi-occlusive surface film, reduces transepidermal water loss, and stabilises emulsions; in combination with honey and olive oil shows clinical improvement in atopic dermatitis and psoriasis.
Why we tier this moderate
3 cited papers across 2 countries. The mechanism is well-described and there's at least one controlled trial in the literature, but we tier this Moderate rather than Strong to stay honest about how many specific papers we cite directly.
