Questions

Common questions

Is the La Roche-Posay Retinol B3 Serum or the The Ordinary Retinol 1% in Squalane better?
Neither is universally better — they share 70% active-ingredient overlap, so for the actives that drive results they're close. The The Ordinary Retinol 1% in Squalane is the more budget-friendly option, while the other may differ on texture, finish and supporting ingredients. Pick based on your skin's priorities rather than a single 'winner'.
What's the difference between the La Roche-Posay Retinol B3 Serum and the The Ordinary Retinol 1% in Squalane?
Both are serums that share Retinol. Where they differ: they sit in different price tiers (Premium vs Budget); the La Roche-Posay targets Fine Lines, Photoaging Prevention; the The Ordinary targets Aging, Dark Spots.
Are the La Roche-Posay Retinol B3 Serum and The Ordinary Retinol 1% in Squalane dupes for each other?
They share 70% active-ingredient overlap based on published INCI lists, so one can stand in for the other on the actives that matter — chiefly Retinol. A dupe matches the hero actives, not the full sensory experience, so expect differences in texture, fragrance and exact concentrations.
Can I use the La Roche-Posay Retinol B3 Serum and The Ordinary Retinol 1% in Squalane together?
They both fill the serum slot in a routine, so you'd normally pick one rather than layer both. If you want to use both, treat one as your daytime option and the other for evening, and patch-test when introducing anything new.
