So here's the deal with this Spirulina Radiance Boosting Serum – it's basically like a power-up for your face. You've got spirulina in there (yeah, that superfood stuff), and it genuinely works wonders on pretty much any skin type. What it does is lock in moisture and give you that glow everyone's always trying to achieve with filters. The blue micro-algae thing sounds fancy, but really it just means your skin cells get moving faster, which translates to better tone and that fresh, awake look we're all after.If you're tired of looking tired, this is your answer. It comes in this gorgeous deep purple bottle – only 30ml, but a little goes a long way. Just work it into your routine after cleansing, and you'll actually see a difference. It's one of those products that feels luxe but actually delivers on what it promises, which is rare these days.
