Known for creating gentle-yet-effective formulas that won't irritate sensitive skin, First Aid Beauty has channeled its efforts into create a formula to help fade the appearance of dark spots, sun spots, hyperpigmentation, post-acne marks, you name it. The First Aid Beauty Facial Radiance Niacinamide Dark Spot Serum (£38) features niacinamide (hence the name), a gold-standard skin-care ingredient lauded for its ability to improve skin tone and texture. And in lieu of ascorbic acid, which can often cause irritation in sensitive types, the brand has added licorice root (to soothe and brighten), golden kiwifruit (a fruit that contains a ton of vitamin C), and something called undecylenoyl phenylalanine, which helps reduce the appearance of hyperpigmentation.
