Why this dupe
The proof is in the ingredients, not the price
Niacinamide, Lactic Acid and other key ingredients appear in both full ingredient lists.
In the full lists, 6 ingredients overlap.
Who it's for
La Roche-Posay Effaclar Ultra Concentrated Serum shares a tone-evening vitamin B3 and a mild exfoliating acid with YSL Pure Shots Stability Reboot Bi-Essence. Hydration, brightening and gentle exfoliation show up on both lists.
A soothing agent and a wrinkle-care active sit only in the YSL essence, so anti-aging depth stays on the luxury side.
The La Roche-Posay serum also skips the fragrance and limit-regulated preservatives noted in the YSL formula. At about 50% cheaper, starting with the shared actives is the easier move.
What works and what to weigh
- Moisture on par with the original
- Free of paraben, silicone and mineral oil
- About 66% cheaper
- –The original adds ingredients for firmness and soothing.

Key shared ingredients · 2 (1 uncommon)
The key ingredients both products share — the basis for the match.
A Korea MFDS-notified brightening vitamin B3, also widely used for hydration and barrier support.
An AHA that gently clears away dead surface cells.
The lists are long, so the reference line lands late and the reading becomes unreliable. So we cannot tell how much of each shared ingredient these two products actually contain, and we would rather say that than guess.
Full ingredient comparison
Both full ingredient lists compared. More shared ingredients means a closer match.
Ingredients are listed by amount. Below 1%, brands may list them in any order, so ranking there means little.
Compared by full ingredient list. It does not mean concentration or texture are identical, and prices are as of the listed time.

Before you reach for this dupe
- It contains exfoliating acids, so daytime sunscreen is a good idea.

How we pick a dupe
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.
