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 834 ratings, and we do not reproduce customer reviews.
The reviews we read split fairly clearly. The recurring praise is gradual brightening: several people describe uneven patches looking lighter after a few weeks of steady use, and a glow that turns up well before any change in tone does. Complaints tend to be sensory rather than functional. The scent puts people off, the texture is thicker and less even than expected, and more than one buyer opened a bottle that had already darkened to deep yellow or orange, which then left a tint on the skin. A few noticed nothing beyond greasiness. With roughly a tenth of all ratings at one or two stars, the sceptics are a genuine minority rather than a stray voice.
Praised for
- gradual fading of dark patches with consistent use
- visible glow and brightness after about a month
- no stinging or sensitivity reported, even by retinoid and acid users
- absorbs without much fuss
Criticised for
- unpleasant smell, mentioned repeatedly
- thick or uneven texture that shaking does not fix
- bottles arriving already darkened, leaving a yellow-orange cast
- some saw no change at all, and a few found it drying
