hi crunchies! let’s keep this to the point 🙂 i’ve never posted a DIY hyaluronic acid serum before, so here i am.
for this DIY, you will need something that blends on your behalf for the hyaluronic acid powder, a water-soluble preservative, and patience. this might cost more upfront in bulk ingredients than it would to purchase, but you can make multiple bottles and i think it’s fun to play and mix. it’s also fun to learn, as it can further help you read labels and understand what you’re actually paying for.
since we’re only making 2 ounces, let’s use a sturdy, more powerful milk frother. it won’t “froth” water, so it’s fine. since i’m sure other formulators will read this and scream in horror, please note i’m aware that a high-powered immersion blender is the best option, but we’re only working with 60 mL of liquid, so i provided a realistic option to a $350 hand blender.
hyaluronic acid serums will only ever have a 0.1% to 2% concentration of hyaluronic acid, because it swells in water and turns into a gel. you can’t add more, or it won’t dissolve. the low concentration doesn’t mean it’s not an active ingredient, but i do think the aqueous base it’s dissolved in is important. let’s opt for a skin-supporting hydrosol instead of plain water.
the molecular weight of hyaluronic acid is also important. we want HIGH molecular weight (HMW-HA). here’s an article i like for explaining things in an easy-to-understand and no-frills format.

- 2 ounces favorite hydrosol
- i had cucumber at the time, but rose or tulsi would be lovely; choose based on what your skin needs
- 1/8 teaspoon hyaluronic acid powder
- plant-based colorant, if desired
- i’m a huge fan of cold-infusing butterfly pea flowers to give a beautiful indigo shade to the final product. it is rich in the antioxidant anthocyanin, briefly mentioned here. many companies are starting to include butterfly pea flowers in their formulations… 😉
- water-soluble preservative
- add your water-soluble preservative to your hydrosol base and stir well, ensuring it’s completely dissolved
- add your plant-based colorant, if any. if using butterfly pea flowers, this will be like making a room temperature ‘tea’ and then straining the flowers back out
- completely submerge your frother and SLOWLY sprinkle in the HA as little at a time as you can. it will gel up.
- bottle in air-tight container. a pump or dropper bottle might be good options.
STORAGE: store in cool, dry area away from direct sunlight. toss after 3 to 6 months, always monitoring for changes in smell, appearance, or texture.
USE: use daily before creams, oils, and butters.
