Paula’s Choice 1% Retinol Booster vs Cos De BAHA Niacinamide 10 Serum

The Paula’s Choice 1% Retinol Booster and Cos De BAHA Niacinamide 10 Serum make for good, if unremarkable, Facial Serums at their respective budgets.

With that said, while they both should serve reasonably well, you might want to look into other options at the $50 and $12 price points - it's likely that there are some better alternatives available.

If you want to learn more about the Paula’s Choice 1% Retinol Booster and the Cos De BAHA Niacinamide 10 Serum, however, we prepared a summary of the information that we have:

The Paula’s Choice 1% Retinol Booster hasn't managed to get enough recognition from sources that do high-quality hands-on testing and therefore didn't make it into any relevant roundups. That, by itself, makes it difficult to recommend.

Moving on to the Cos De BAHA Niacinamide 10 Serum: no sources that perform reliable and objective hands-on testing have included it in their Facial Serum roundups, which usually means that a product doesn't make for a good purchase.

As a last step, we wanted to do a head-to-head Paula’s Choice 1% Retinol Booster vs. Cos De BAHA Niacinamide 10 Serum comparison of their review performance but, unfortunately, weren't able to find any review ratings on either product.
