Anthelios Ka SPF50+

Shares titanium dioxide, avobenzone (butyl methoxydibenzoylmethane), octocrylene and the bis-ethylhexyloxyphenol methoxyphenyl triazine filter with the Anthelios, giving a very similar broad-spectrum UVA/UVB profile, but it lacks the ethylhexyl triazone/drometrizole trisiloxane combo and the extra Mexoryl-type filter that make the original's UVA protection more robust.

Shares titanium dioxide, avobenzone, octocrylene, bis-ethylhexyloxyphenol methoxyphenyl triazine and terephthalylidene dicamphor sulfonic acid, hitting most of the same UV filters as the original, but lacks ethylhexyl triazone and drometrizole trisiloxane for full UVA coverage parity.

Overlaps on titanium dioxide, avobenzone, bis-ethylhexyloxyphenol methoxyphenyl triazine and drometrizole trisiloxane, covering most of the same filter chemistry, but it swaps octocrylene's role and uses diethylhexyl butamido triazone instead of ethylhexyl triazone, so the exact filter blend isn't identical.

Shares titanium dioxide, avobenzone, octocrylene and terephthalylidene dicamphor sulfonic acid, but adds homosalate (not in the original) and is a spray format missing ethylhexyl triazone, so the filter system diverges more than the lotion versions.

Shares titanium dioxide, avobenzone and octocrylene, but relies heavily on Mexoryl SX/XL instead of the original's ethylhexyl triazone, bis-ethylhexyloxyphenol methoxyphenyl triazine and drometrizole trisiloxane, meaning the core UVA filter technology is genuinely different despite some overlap.
