Anti-acne exfoliating serum, AHA & BHA

Formula: AP35410

Phase Ingredients for ~100 ml % Quantity
A flat mineral water 54 54 gr
A witch hazel water 30 30 gr
A glycerin 2,2 2,2 gr
A xanthan gum 0,2 0,2 gr
B natural salicylic acid, BHA 10 10 gr
B AHA fruit acids 3 3 gr
B cosgard 0,6 20 drops

Sanitize the dedicated containers and utensils you will work with, details in the general safety guidelines.

Preparation method:
Add the liquid ingredients from phase A to a beaker and mix. Sprinkle with xanthan gum, stirring vigorously until completely dispersed. Leave to rest for approximately 10 minutes, then mix well.

Over the composition of phase A, the ingredients of phase B are added one at a time, thoroughly mixing after each one. The resulting solution is transferred to the dedicated container. Shake the container before use.
Optimal pH level: ~3,5. Given that the pH may vary depending on the batch for fruit acids, salicylic acid but also for floral waters, at the end it may be necessary to add lactic acid to obtain the optimal acidity for this serum.

The result is a fluid serum, suitable for acne-prone skin or skin affected by blackheads. Apply on clean skin, preferably in the evening, once a day or 2-3 times a week depending on skin tolerance. The serum can be applied either by spraying and spreading on the skin with clean fingers, or with a cotton pad. It can also be used on the body.
After finishing a container, depending on the results obtained, you can pause for a few weeks or continue the treatment.
During a chemical exfoliation treatment, UV protection of the skin is recommended, especially during summer. It is recommended that people with sensitive skin perform a tolerance test before using products containing AHA and BHA.
