First Aid Beauty's Ultra Repair Hydrating Serum is a genuinely good offering by the brand because it has the potential to live up to most of its claims. A sheer water-based gel, this lightweight formula is fragrance-free and contains a soothing mix of anti-irritants, antioxidants, and reparative ingredients. Given its gel texture, it is suitable for any skin type, but especially for oily skin, including the acne-prone.
