Pros
- My tretinoin redness and inflammation was significantly reduced and my skin no longer looked angry when using this serum
- Gentle and hydrating
- Sinks into skin well
- Mildly hydrating
- Very affordable
- Contains skin lightening and brightening ingredients such as tranexamic acid and niacinamide
- Did reduce the activity of melanocytes such that on (for example) warmer days my skin and hyperpigmentation did not darken

Cons
- Does not lighten sun spots or melasma
- Low dose niacinamide and tranexamic acid dose is below recommended guidelines for lightening melasma on its own, but appropriate when used in conjunction with hydroquinone
- There is a lot of product and a little goes a long way, however the formula will go off before you can use it all
- Not in a UV protective bottle

Should you buy it?
Yes If you want to reduce redness, PIE/PIH and as a supportive treatment when on a course of tretinoin and/or hydroquinone

No If you want to use this to reduce sun spots and melasma. This product alone will not be effective enough to treat these conditions but will help in calming down melanocytes.
