INGREDIENTS

  • 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

FORMULA

HOW TO

  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.

enjoy!

diy formulation educational series: luxury face oil

hello friends! i’m back again with another DIY face oil formula, taking inspiration from a $225 / 0.67 fl ounce night serum. picking apart ingredient lists is a fun hobby for me, however weird that sounds.

it has really great ingredients, but can be DIY’ed because – 1. it’s completely anhydrous; and 2. doesn’t need to extract from whole plant materials.

please note the upfront costs are high (still lower than the price of the finished 0.67 fl oz product), but will yield multiple batches.

here are the original ingredients:

Opuntia ficus-indica (Prickly Pear) Seed oil*, Supercritical Rosa Mosqueta (Rosehip) fruit oil extract*, Sclerocarya birrea (Marula) seed oil*, Supercritical Borago Officialis (Borage) Seed oil extract*, Adansonia digitate (Baobab) seed oil*, Caulophyllum Inophyllum (Foraha) oil*, Argania spinosa (Argan) nut oil*, Curcubita pepo (Pumpkin) Seed oil*, Camelina sativa (Camelina) oil*, Nigella sativa (Black Cumin) oil*, Ubiquinone (Coenzyme Q10), Supercritical Hippophae Rhamnoides (Sea Buckthorn) Berries extract*, Supercritical Hippophae Rhamnoides (Sea Buckthorn) seed extract*, Caprylic/Capric Triglyceride and Pheonix Dactylifera (Date) Seed Extract, Supercritical Rosmarinus officinalis (Rosemary) extract*, essential oils of: Boswellia Carterii*, Helychrisum italicum*, Daucus carota*, Commiphora myrrha*, Pelargonium x asperum*, Cananga odorata*, Jasminum grandiflorum L. extract*, Elettaria cardamomum L*, Rosa centifolia extract*

aren’t the ingredients great? my personal favorite oil for skincare is prickly pear seed oil. it’s pretty pricey but oh-so-worth-it. it’s nice to see it at the top of the list!

formulation notes:

ingredients have to legally be listed by % contribution in descending order. knowing that, when creating a diy dupe we want to look for the “1% line.”

one “1% line” we sort of could use is the ubiquinone, aka co-q10. this is a bright orange powder and is typically used at 0.3-3%…  a bigger range than is helpful to us.

however, next in the formula is sea buckthorn berry oil. we know that SBO can be used up to 1% topically without staining, so normally we could cut it there. since co-q10 is also bright orange, let’s call the SBO at 0.5%. if you’re still following, anything above that is >0.5% contribution, and anything below is less.

black cumin seed oil is very near and dear to my heart, but it is quite a strong smelling little guy… very medicinal. i will assume, due to the strong scent, it’s also lower on the lower side of the formula % contribution.

do you see where instead of the individual ingredients being separated by a comma they’re instead connected with an “and”? that means it’s a pre-blended product. hint: it’s “caprylic/capric triglyceride and pheonix dactylifera (date) seed extract.” in this case, the product is known as d’orientine s. it’s typically used at 1-2.5% concentration, but i think it’s used less here, given that SBO is listed ahead of it.

and lastly, the rosemary extract used here is an antioxidant (not a preservative), and is typically used at up to 0.5%.

for the rest of the oils: prickly pear seed oil is super pricey, so let’s assume it’s no more than 20%. that being said, the blend of the main carrier oils could be anything from an equal split to being mostly prickly pear seed oil. this is where your personal preference and skin type would come into play. regardless, tamanu oil can be a little thick and greasy, so let’s assume it’s not a huge part to the overall formula, even though it’s listed towards the top.

formulation adjustments: 

let’s make the EOs optional, due to high upfront costs, as well as a safety precaution. if you’re an aromatherapist – first of all, you’re cool; second of all, blend EOs to your heart’s content. either way, if you choose to add these EOs, please do not use more than a total contribution of 1%.

the original formula is NOT suitable for blemish-prone skin, but this DIY will be as close to the original as i can get. if you want something for blemish-prone skin, try  this post for the best and worst facial oils and this post for an overview on different oils and their comedogenic ratings. 

diy formula:

NONE of the links provided benefit me in any way. they’re here to save you time and energy searching for them.

total cost: $141.55

total possible 1 fl ounce batches*: 2.5

*if using 15 mL prickly pear seed oil as your constraining factor… if you repurchase that, you will have many more batches from the other oils
**minimum amount saved… assuming only 2 purchased bottles, not 3 to fully cover the 2.5 oz of dupe you can make

 

what do you think? do you think this would be a luxurious gifting idea?
