What buyers actually say
We read a sample of the Amazon reviews for this product and describe the pattern in our own words. It is a sample, not a survey of all 1,014 ratings, and we do not reproduce customer reviews.
An overnight product with a fairly settled reputation in our sample: reviewers apply it before bed and report smoother, softer skin and less obvious pores by morning, several within the first week or two. Repeat purchase is common, and a few pair it with the brand's pore pads. No one in the sample reports breakouts. The reservations are measured rather than angry. Two three-star reviewers liked how their skin felt but were not convinced their pores had actually changed size. One reviewer had pilling when layering it with other products and adjusted their routine. Another sensibly notes the exfoliating acids leave skin sun-sensitive and rinses it off in the morning.
Praised for
- Pores look smaller and skin smoother by morning
- Noticeable results within a week or two for many
- No breakouts reported in the sample
- Frequent repeat purchases, pairs well with the pore pads
Criticised for
- Some unconvinced pores genuinely shrink
- Can pill when layered with other products
- Acids increase sun sensitivity, so daytime care is needed

What is niacinamide?
