Hyaluronic Acid Serum: 3 vs. 5 vs. 8 ingredients

In this post I’m going to teach you how to make three different hyaluronic acid serums; one with 3 ingredients, one with 5, and one with 8. Each formulation builds on the one before it so you can see how to modify and expand on (or, if done in reverse, simplify!) a serum formulation.

I’ve packed this post full of helpful links, so for the best learning experience please click through and read the ‘bonus’ material as well. Happy making!


5% Lactic Acid + Hyaluronic Acid Exfoliating Serum

Reveal even, smoother, glowing skin with this 5% Lactic Acid + Hyaluronic Acid Exfoliating Serum formulation. Gentle AHA lactic acid offers mild chemical exfoliation, backed up with a blend of skin-soothing and hydrating actives to reduce inflammation potential and keep your skin hydrated and happy. I’ve had a ton of requests for AHA (alpha hydroxy acid) formulations over the years, and today I’m finally sharing one—I hope you like it!


Brighten & Boost Facial Serum

This cold-processed face serum does a whole lot of awesome things: it hydrates, brightens, reduces fine lines, evens out skin tone, boosts barrier function, soothes, softens, and might also know exactly which mango in that display at the grocery store will taste the best (no promises about that last one, though 😝). If you watched my recent ingredient deep-dive into niacinamide and have been thinking you should make something awesome with it, I think this Brighten & Boost Facial Serum is a fabulous choice!

Goji & Açaí Superfood Face Cream

As winter drags on, my skin needs all the hydration and love I can send its way. This formulation pairs two superfood ingredients with a couple fabulously hydrating ingredients and some potent antioxidants to help my skin stay soft and moisturized in the face of dry, wintery weather.
