Alpyn Beauty Wild Nettle & Niacinamide Firming Serum: This silky serum hydrates and soothes, and it really improves the appearance of both fine lines and wrinkles as it firms. It’s made with nettle, which is counterintuitively calming for skin and plays a role in activating vitamin C, as well as rambutan, a plant-based alternative to retinol that’s packed with skin-glowifying niacinamide. Use it mornings and evenings for baby-soft skin that’s firm and luminous.1 fl oz / 30 ml.
