Smell is an incredible sense. It can transport you to your childhood garden or grandmother's kitchen -- and it can completely change your mood. Take a whiff of lavender, and suddenly you're in Provence -- and totally relaxed.

The French brand L'Occitane has been using Aromatherapeutic oils in its products for more than 40 years, and their latest launch, Aromachologie, is the culmination of decades of research. There are two lines within the Aromachologie collection: relaxing and revitalizing. The relaxing products contain a blend of lavender, bergamot, mandarin, sweet orange and geranium. The result is subtly floral with a hint of soapy-ness. The revitalizing products are made with orange, grapefruit, mint, lemon and rosemary -- a seriously zesty blend.

Whether you need help decompressing after a stressful day or you could use a mid-afternoon pick-me-up that doesn't come in a Styrofoam cup, these products are just the ticket.

The base of the L'Occitane Aromachologie Relaxing Massage Body Oil, $34, is sweet almond oil from Provence. It's incredibly luxurious and nourishing. Add to that the blend of relaxing essential oils, and you've got the makings of a truly spectacular massage -- even if you have to DIY.

Sachets are one of those magical products you don't realize you need until you have them. And when you do have them, you want to put them everywhere -- sock drawer, closet, under your pillow, next to the toilet … the list goes on. The L'Occitane Aromachologie Relaxing Perfumed Sachets, $12, have the added benefit of being -- you guessed it -- relaxing. Every time you catch a whiff, your stress level drops a few notches.

A bath is the consummate way to unwind at the end of a long day. A bath with L'Occitane Aromachologie Relaxing Bath Salts, $24, is pure transcendence.

If you prefer an end-of-day shower to life your spirits, you'll love the L'Occitane Aromachologie Relaxing Shower Gel, $20. It creates a creamy foam and leaves skin moisturized.
