  • cucumber hydrosol
    • deeply hydrating, calming, and conditioning
    • fresh and earthy smelling
    • gentle enough for all skin types
  • xanthan gum
    • gelling agent; used in miniscule quantities
    • found in your local grocery baking aisle
  • aspen bark powdered extract
    • water-soluble preservative
    • skin-conditioning
    • high in salicin
  • optional – a lightweight carrier oil
    • suggested: prickly pear seed oil or amaranth seed oil, both great for all-things-“eye”
    • note: xanthan gum can hold about 1% oil without needing an emulsifier, but it can separate over time
  • optional – water-soluble colorant



  1. in your bottle of cucumber hydrosol, sprinkle in your aspen bark powder and shake well.
  2. in the same bottle, gently and evenly sprinkle the xanthan gum across the top of the hydrosol. let sit for a few hours until the gum is fully swelled/hydrated. you can shake it after a few hours to make sure, but not before (or else you will get clumps called “fish eyes”)
  3. add up to 1% of your oil. shake well.

apply to clean skin before any creams or oils. store in a cool, dry area, away from sunlight. toss if the smell or color turns.

BONUS: you can easily turn this into a hyaluronic acid serum, since it’s mostly hydrosol. if you opt for that, omit the xanthan gum.




top 5 / bottom 5 face oils commonly used

the green beauty world is saturated with oil blends right now (pun kind of intended). to help try and guide you, i’ve compiled a list of the top 5 and bottom 5 most commonly used oils, – – NOT of all time. that can be another post, heehee. if i was including the top 5 of all time, you already know i’d be including what i use in The Botanical Dew 😉

with less than 2 months left before this blog’s hiatus, i’m trying to arm you to be a more educated consumer as best as i can. it’s why i started this blog, after all!

skincare is incredibly personal, so what really works for one person could be disastrous for the next. let’s keep in mind this is all relative and meant to serve as a loose guide to understanding oils and their components. and plus – i think all of these are great for body and hair.

to rank these, i’m using what i’ve found to be the best way to cross-check if an oil would do well on your face – 1. comedogenic rating; and 2. oleic acid percentage.

comedogenic rating is how likely the oil is to clog your pores, on a scale of 0 (not likely) to 5 (very likely).

i use oleic acid as an indicator because i like to work off the norm, not the exception*. oleic acid is the naturally occurring omega-9 fatty acid, that your body produces. it commonly disagrees with oily, or sensitive, or acne-prone skin. linoleic acid, omega-6, is the better, and lighter, fatty acid that your body does not produce. it reduces clogged pores. this is not to be confused with linolenic acid, omega-3, which commonly clogs most people’s pores and should be avoided for use on your face.

here’s my take on the bottom and top oils most commonly used in face oils (not of all time).


5. camellia seed oil

  • comedogenic rating – 2 to 3
  • oleic acid – 60-80%

4. macadamia nut oil

  • comedogenic rating – 3
  • oleic acid – 65%

3. avocado oil

  • comedogenic rating – 3
  • oleic acid – 70%

2. marula oil

  • comedogenic rating – 3 to 4
  • oleic acid – 70-75%

1. coconut oil

  • comedogenic rating – 4
  • oleic acid – 10%


5. grapeseed oil

  • comedogenic rating – 1
  • oleic acid – 20%
  • linoleic acid – 70%

4. argan oil

  • comedogenic rating – 0
  • oleic acid – 45%
  • linoleic acid – 40%

3. squalene (plant-derived or in whole plant form like amaranth oil)

  • comedogenic rating – 0
  • oleic acid – n/a (ex: amaranth – 25%)
  • linoleic acid – n/a (ex: amaranth – 55%)

2. hemp seed oil

  • comedogenic rating – 0
  • oleic acid – 10%
  • linoleic acid – 60%

1. prickly pear seed oil

  • comedogenic rating – 1
  • oleic acid – 20%
  • linoleic acid – 60%
  • palmitic acid – 20%
