IREN - rebeczema review for Star Light Brightening Serum

- brightening serum aimed at reducing and preventing hyperpigmentation - yuzu extract, 2% alpha arbutin, 5% niacinamide - ideal for dark spots or dull skin - thoughts: I prefer ascorbic acid (pure vitamin C) as my go-to brightening ingredient; however it can be a bit irritating at times. This serum is ideal for days when my skin is more sensitive since it’s so gentle.
