Three-Ingredient Coffee Sugar Scrub

• 1 part coffee grounds • 1 part coconut oil • 1 part brown sugar

Combine all ingredients in a bowl to form a gritty paste. Smooth over your skin in the shower when you need an invigorating, all-over exfoliation. The caffeine in the coffee has a natural plumping and tightening effect. Store excess in an airtight container.

Oil-Reducing Cucumber Face Mask

• 1/2 cucumber • 2 tablespoons ground oatmeal • 2 teaspoons lemon juice • 1 tablespoon honey

Cut the cucumber into cubes and combine with the rest of the ingredients in a blender. Blend until smooth. Apply to a clean, dry face and let it sit for 15 minutes. When you rinse, scrub in circular motions to reap the exfoliating benefits of the oatmeal.

Soothing Pumpkin Face Mask

• 1/4 cup pumpkin puree • 1 egg • 1 tablespoon honey • 1 tablespoon milk

Mix all ingredients in a bowl and apply to the face with a mask brush -- a clean paintbrush also works. Leave on for 20 minutes or until mask starts to crack. Wash off with warm water. Chock-full of skin savers like vitamin A (for smoothing wrinkles) and vitamin C (for lightening dark spots), the pumpkin will leave your skin glowy and refreshed.

Scalp-Clarifying Clay Hair Mask

• 1/2 cup bentonite clay (find it for cheap on Amazon) • 1 tablespoon coconut oil • 1 tablespoon castor oil • 1 tablespoon sweet almond oil • 6 tablespoons apple cider vinegar • 3 tablespoons water

Start by adding clay to a clean bowl. Mix in the oils, followed by the apple cider vinegar and let the mixture sit for 15 minutes. (This will cause a foamy reaction.) Finally, add the water and blend the ingredients to a yogurt-like consistency. Apply to hair and let sit for 30 minutes before washing and conditioning.
