Whether each product contains ingredients some prefer to avoid. A check means it does not contain them — a preference, not a safety verdict.
Watch-outs
Fragrance, parabens, etc. that some prefer to avoid. Products within labeled limits are generally fine.
Biotherm
La Roche-Posay
Compared by full ingredient list. It does not mean concentration or texture are identical, and prices are as of the listed time.
What the ingredients show
The two products share a couple of core actives. One is a mineral UV filter that reflects sunlight, listed by the KFDA; the other is an organic UVB filter.
Across the full lists, both focus on moisture and uv. They don't share every ingredient, but the payoff lands in a similar place.
Neither product lists paraben and mineral oil. The Biotherm side does include fragrance, so if fragrance or preservatives are a concern, the La Roche-Posay option may sit easier.
A close ingredient list doesn't mean the strength or the texture matches. The same ingredient can feel different depending on how much is used and how it's made, so treat the shared ingredients as a starting point rather than a promise.
The price gap is about 53%, or roughly ₩42,430. If you want a similar ingredient makeup at a lighter price, this is a sunscreen worth trying first.

This comparison is based on full-ingredient (INCI) data published under cosmetics law.
Shared ingredients mean the full-ingredient lists overlap, not that blend concentrations match; how a product feels can differ by formulation and origin.
Prices are market-verified against Naver and Coupang and may differ from official store prices; discounts and temporary changes may not be reflected, so check the seller before buying.
