Stinging Sensation with Stabilized Vitamin C Serum

Thank you for your feedback on the Stabilized Vitamin C (Natural-C Glycol™) Serum. It's good to hear you like the product overall.

The stinging sensation you feel on your cheeks when applying the serum can sometimes occur with vitamin C products, especially those containing L-Ascorbic Acid at a low pH.

The Stabilized Vitamin C (Natural-C Glycol™) Serum has a pH in the range of 2-3. This low pH is necessary for L-Ascorbic Acid to be effective, but it can also cause a tingling or stinging feeling, particularly on sensitive areas like the cheeks or if your skin barrier is compromised.

This sensation is often a sign of skin sensitivity or mild irritation. It's not necessarily "normal" in the sense of being harmless or comfortable for everyone, but it is a known potential side effect of acidic vitamin C formulations.

Recommendations:

• Monitor your skin: Pay attention to whether the stinging is accompanied by other signs of irritation like redness, dryness, or peeling. If irritation worsens, consider reducing the frequency of use or discontinuing the product.
• Skin Barrier: Ensure your skin barrier is healthy. Using hydrating and soothing products in your routine can help.
• Alternative Vitamin C: If the stinging persists and is bothersome, you might consider trying a product with a lower concentration of vitamin C or a different, less acidic form of vitamin C in the future.

While some people tolerate this sensation, it's important to listen to your skin and adjust usage as needed.
