Common questions

Is La Roche-Posay MelaB3 Serum Intense Anti-Dark Spot Serum fragrance-free?

No. Fragrance (listed as "Parfum") is the 32nd of 32 ingredients.

Does La Roche-Posay MelaB3 Serum Intense Anti-Dark Spot Serum contain alcohol?

No drying alcohol (alcohol denat. or ethanol) is listed.

Is La Roche-Posay MelaB3 Serum Intense Anti-Dark Spot Serum safe for fungal acne?

It contains 2 ingredients that fungal-acne (Malassezia) guides usually avoid: fatty-acid esters & glycerides (peg-20 methyl glucose sesquistearate, retinyl palmitate). How much they matter depends on the amount and the rest of the formula. The evidence comes mainly from lab studies of yeast growth, and fungal acne needs a diagnosis from a GP or dermatologist.
