How to Use

1. Measure the desired amount of lactic acid powder using a precise scale.
2. Dissolve in distilled water, aloe vera gel, or your preferred carrier base.
3. Adjust pH to between 3.5–4.0 for optimal skin compatibility using a pH meter and a neutralizer (e.g. sodium hydroxide solution).
4. Perform a patch test on a small area before full application.
5. Always follow with a broad-spectrum SPF moisturizer during the day, as AHAs can increase sun sensitivity.

Tip: Start with a lower concentration (5–10%) in your formulation and gradually increase as your skin builds tolerance.
