Suggested final pH

pH guide coming soon

Check the finished mixture

Measure after all ingredients, preservative and final water have been incorporated and the HA is fully hydrated. Use a calibrated pH meter suitable for the serum or cream, at room temperature.

If adjustment is needed, use a formula-compatible diluted pH adjuster in small, measured additions; mix and remeasure. Recheck after 24 hours at the same temperature. There is no fixed number of drops that works for every batch.

The target must fit every ingredient and the preservative. Reaching it does not establish safety or shelf life.

Confirm the target and adjuster compatibility before following the guide.

Before preparing this formula

  • Use free-base L-arginine, not arginine hydrochloride or a supplement blend.
  • Mixing aid only. Do not apply directly to skin. Stay within the complete formula’s ingredient limits.
  • Wear splash goggles and gloves. Keep away from children.
  • Make fresh for the current mixing session and discard the remainder; no preservative or stored shelf life is established.
