See all 8 Yves Saint Laurent dupes →As of Jul 18 · Prices reflect public listings on stores such as Coupang and may vary by store or promotion.
Why this dupe
The proof is in the ingredients, not the price
Ethylhexyl Methoxycinnamate, Titanium Dioxide,CI 77891, Drometrizole Trisiloxane, Terephthalylidene Dicamphor Sulfonic Acid and other key ingredients appear in both full ingredient lists.
In the full lists, 40 ingredients overlap.
Who it's for
La Roche-Posay UVIdea Anthelios Tone-Up Light Cream mirrors the UV filter lineup of YSL Top Secrets Instant Tone-Up UV almost item for item. For tone-up sun protection, both are aiming at the same job.
Shea butter and a wrinkle-care active belong only to the YSL cream. The La Roche-Posay cream carries preservatives with regulated usage limits, so check them if your skin reacts easily.
At about 79% cheaper, wearing it generously every day is a much easier habit to keep.
What works and what to weigh
- Moisture on par with the original
- Free of paraben and mineral oil
- About 74% cheaper
- –The original adds ingredients for firmness and exfoliation.

We compare the full ingredient lists and only pair products that share core actives. Prices are checked against market listings, and ingredients with Korea MFDS usage standards are flagged on the page.
Disclaimer
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 and performs can differ by formulation and ingredient grade.
Prices are market-verified against stores such as Coupang and may differ from official store prices; discounts and temporary changes may not be reflected, so check the seller before buying.
For sensitive skin, eczema, pregnancy or other special cases, please do not decide on this analysis alone and consult a dermatologist.
