- The "base" or "solvent" you use can range from incredibly simple to quite complex. Your choice impacts the serum's texture, hydration properties, and potentially its stability. There's no single "best" option—it depends on your goals.
- Our team has worked with numerous formulation bases. Here's a breakdown of the most common choices.
- Distilled Water
- Inexpensive, readily available, excellent solvent for GHK-Cu. Creates a very thin, watery serum.
- Offers no additional skincare benefits (e.g., hydration). Can evaporate quickly from the skin.
- This is the purest, most straightforward approach. It's perfect for researchers or DIYers who want to isolate the effects of GHK-Cu without confounding variables. It's also great for use with microcurrent devices.
- Hyaluronic Acid (HA) Serum
- Provides intense hydration, gives the serum a more viscous, pleasing texture. Can be purchased as a pre-made base.
- You must use a preservative-free HA base, as some preservatives can interact with peptides. The quality of the HA matters.
- A fantastic choice for cosmetic use. The combination of HA's plumping hydration and GHK-Cu's regenerative signals is a powerful duo. We recommend a base with multiple molecular weights of HA for multi-level hydration.
- Glycerin & Distilled Water Mix
- Glycerin is a powerful humectant, drawing moisture into the skin. It's inexpensive and creates a slightly thicker serum than water alone.
- Can feel sticky if the concentration of glycerin is too high (we recommend no more than 5-10%). Requires precise mixing.
- This is a classic, cost-effective way to add humectant properties. It's a solid middle-ground between plain distilled water and a more complex hyaluronic acid serum. Just be mindful of the texture.
- For those just starting out, a high-quality, pre-made Hyaluronic Acid serum base is often the easiest and most rewarding option. It removes the guesswork of creating a cosmetically elegant texture from scratch.
