I've been trying out the odd facial serum here and there since they're meant to be so effective and I have the worst dry skin ever. I haven't been impressed with many of them, especially since the first one I tried was by La Mer - it was totally amazing, but very expensive!
Kiehl's Ultra Facial Micro Serum is the first reasonably priced serum I've tried that I truly love! It's light in texture and doesn't leave skin feeling oily or greasy like some of its competitors. It feels good on the skin and is easy to apply. I really like this product a lot!
What serums are you using at the moment? I am always looking for a great skincare recommendation!
