1. Living Proof Prime Style Extender - If Jennifer Aniston is the co-owner of a company that specializes in hair products, you know it's going be an EXCELLENT product! You can use the hair primer alone or with other products. It holds other products longer so your hair style lasts and doesn't fall out- AND IT WORKS!
2. bareMinerals Mineral Veil - I don't like wearing foundation everyday so I use this mineral veil instead. It's meant to use after you've applied all your makeup, and you simply brush the powder over your face. I buy the tinted powder, which gives me a little more colour (since I'm extremely porcelain).
3. Benefit They're Real Mascara - The. Best. Mascara. Ever. Enough said.
4. Clarisonic Mia - This is an expensive product, so I bought it for myself for Christmas! Since I've started using it my skin is less oily, has less breakouts, and stays smooth (amoung other things). It's by far my favourite product, the only downside is the spin brushes are expensive, but they're cheaper when you order them online- see here.
Splurging is not necessary, but now that I've tried my four favourite splurge items I'll likely keep them in my daily routine. And, since it's ONLY four products it doesn't "break the bank" too much.
