Toner Formula for Clogged Acne and Oily Skin: Review and pH

Here is the analysis of your toner formula:

Suitability of the Formula:
The formula uses key ingredients suitable for clogged acne and oily skin, namely Salicylic Acid, a BHA that helps exfoliate within pores and reduce clogging, and Witch Hazel, which helps with astringency and oil control.

However, the concentration of Complex Salicylic Acid at 5% is considered quite high for a toner, which typically uses 0.5% - 2%. This 5% concentration is highly effective for exfoliation and treating acne but also has a higher chance of causing irritation, dryness, or peeling, especially for those with sensitive skin or new to Salicylic Acid products.

pH Value:
Salicylic Acid is most effective for exfoliation when the formula has an acidic pH, generally between 3 and 4. Since this formula contains Salicylic Acid at a 5% concentration, the pH of the formula is expected to be quite acidic.

It is crucial to measure the final pH of the mixed formula and adjust it to the 3-4 range to ensure Salicylic Acid works most effectively and safely. Additionally, the preservative Mild Preserved Eco also has an optimal pH range for its function.

Additional Recommendations:

• You should measure the pH of the finished formula and adjust it to the 3-4 range if necessary. You can use pH adjusters like Lactic Acid or Sodium Hydroxide (use very small amounts at a time).
• Due to the high concentration of Salicylic Acid (5%), it is recommended to patch test the product on a small area of skin before applying it to the entire face. If significant irritation occurs, you might consider reducing the concentration of Salicylic Acid or using this product 2-3 times a week initially and gradually increasing frequency as your skin adapts.
• Using products with Salicylic Acid can make your skin more sensitive to sunlight. Always use sunscreen during the day.
