If there's anyone who knows a thing or two about achieving radiant skin, it's Dr. Howard Murad, and his product line includes something for everyone to attain just that. For those who count dull, flat skin as their nemesis, reach for Murad Environmental Shield Advanced Active Radiance Serum (£99.50). This serum, which is creamy in consistency, works to smooth out discoloration and help reverse damage; it's vitamin C that works its skin-brightening magic. Not only does this powerful antioxidant boost collagen production, but also it improves the clarity and tone of skin. Watch it soak right into your skin, and kiss that blah-looking complexion goodbye.
