Our skincare/carrier oils are the best value on the market. Utilizing both our essential oils (EOs) and carrier oils, you can make your own skin and body care products for a fraction of the price of luxury brands (with the same or better quality!).

Topical Dilution Guidelines:


  • When mixing different scents, make sure to stick to the drop ratio in the chart above. For instance, if you need 8 drops for a mixture and you want to use 2 different oils, you would use 4 drops of one oil and 4 drops of the other (or whatever scent ratio you like as long as the total drops don’t exceed 8).
  • Always start small with the number of essential oil drops and increase to the dilution ratio as desired.
  • These recommended dilutions are for adults 18 and older. Please talk to your health practitioner before using essential oils with children and teens, or when pregnant or nursing.
  • We do not recommend using dilutions above 5% in topical applications. Ten percent is typical of a perfume but not recommended for all-over skin application.
  • Percentages may vary based on the essential oil and application. Essential oils require dilution for topical usage. Do not use undiluted essential oils on your skin.
  • For facial applications such as masks or oils, a 1% or less dilution is recommended. For massages oils and other leave-on body products, we recommend a 2% dilution, and for other rinse-off bath and body products, we recommend 3%.
  • When using essential oils with children, there are more precautions to consider. Please refer to our Essential Oil Safety for Kids Infographic.

NOW® essential oils should never be ingested. Please consult an essential oil book or other professional reference source for suggested dilution ratios. When in doubt, approve by a licensed practitioner before use. See more on essential oil safety.
