FastRelief™ 1609 Usage and Properties

Here is information regarding your questions about FastRelief™ 1609:

1. Is FastRelief™ 1609 similar to a numbing agent?
   Yes, it is similar in that it helps to suppress skin irritation, allergic reactions, or adverse skin responses. It works by reducing the sensation of irritation, heat, swelling, and redness, making it suitable for formulas that may cause unavoidable irritation, such as those containing high concentrations of AHA or Vitamin C.

2. Can FastRelief™ 1609 be used separately, for example, applying AHA first and then FastRelief™ 1609 when irritation occurs?
   The manufacturer recommends using FastRelief™ 1609 in the same formula as the irritating ingredient for optimal effectiveness. Alternatively, it should be applied before the irritating product, not after.

3. Does increasing the concentration of FastRelief™ 1609 affect the duration and amount of irritation reduction? For example, if 1% reduces tingling for 3 minutes, would 2% reduce it for 5 minutes?
   Using a higher concentration of FastRelief™ 1609 (within the manufacturer's recommended range of 1-3%) can provide greater efficacy. The mention of reducing sensation within 3-5 minutes refers to the onset of action, meaning it starts working within that time frame. The effect is not limited to just a few minutes but can last for several hours.

4. If doing a 30% AHA treatment which is very irritating for about 5 minutes, would applying FastRelief™ 1609 afterwards completely and immediately stop the burning sensation, or just reduce it?
   Applying FastRelief™ 1609 can help reduce the burning sensation to a certain extent, and it is designed to immediately reduce the feeling of irritation. However, the degree of relief can vary depending on individual skin sensitivity, especially with a high concentration like 30% AHA. It may not completely eliminate the sensation for everyone, but it should help reduce it. For best results, it is recommended to incorporate FastRelief™ 1609 into the AHA formula or apply it before the AHA treatment, rather than afterwards.

5. Can FastRelief™ 1609 be added to a water-based formula containing Pro Polymer™ at the final step?
   Yes, FastRelief™ 1609 can be added to a water-based formula containing Pro Polymer™. FastRelief™ 1609 is an oil, and Pro Polymer™ can help emulsify it within the water base to create a stable gel texture. FastRelief™ 1609 should be mixed in oil first and added without heat. The final formula pH should be between 3.0 and 6.5, which is compatible with FastRelief™ 1609 and within the functional range for Pro Polymer™ (though Pro Polymer™ is resistant to electrolytes, high amounts might require adjusting its concentration).
