The AGE-R Booster Pro can be used with a variety of skincare products, including those containing acids like AHA or BHA. However, it's important to be cautious when using it with acidic products. Here are some key points to consider: **Pros:** - Enhanced Absorption: The device can help acidic products penetrate deeper into the skin, potentially enhancing their effectiveness. - Convenience: It allows for a more efficient skincare routine by ensuring better product absorption. **Cons:** - Sensitivity: Acidic products can increase skin sensitivity. Using the device with such products might cause irritation or discomfort, especially if the intensity is set too high. - Consistency: It's crucial to use the device consistently to see results, which might be challenging if you experience irritation. **Tips:** - Start Low: Begin with the lowest intensity setting when using the device with acidic products to avoid irritation. - Patch Test: Perform a patch test to ensure your skin doesn't react adversely to the combination of the device and acidic products. - Monitor Skin: Pay close attention to your skin's reaction and adjust the intensity or frequency of use accordingly. Overall, while the AGE-R Booster Pro can be used with acids, it's essential to proceed with caution and monitor your skin's response.
