Unseen Sunscreen SPF 40

Shares the same avobenzone/homosalate/octisalate/octocrylene chemical sunscreen base as Unseen, but adds oxybenzone and swaps the silky silicone-gel texture for a milk lotion.

Overlaps on homosalate, octisalate and octocrylene but replaces avobenzone with drometrizole trisiloxane and ethylhexyl triazone, so UVA protection chemistry differs, plus it's a spray mist not a gel.

Only octocrylene and octisalate overlap; this French formula relies on avobenzone-free triazine/benzotriazole filters instead, so the UV filter profile is quite different.

Shares homosalate, octisalate and octocrylene but has no avobenzone at all, using drometrizole trisiloxane instead for UVA coverage, and comes as a mist.

Only ethylhexyl salicylate overlaps loosely with Unseen's octisalate; this uses an entirely different filter system (triazone, bis-ethylhexyloxyphenol triazine, cinnamate) with no avobenzone, homosalate or octocrylene.
