Using Vitamin C Serums and Sulphur Products Together

Thank you for your question regarding the use of Vitamin C serums (Perfect C or Natural-C Glycol) and Sulphur-containing products (like BioSulphur) in your routine.

Based on the information available for BioSulphur, it is advised to avoid using it with all types of Vitamin C (Ascorbic Acid) because they can react with each other and potentially cause the Vitamin C to deteriorate.

• Natural-C Glycol contains L-Ascorbic Acid, which is a form of Vitamin C that can react with Sulphur.
• Perfect C contains Ascorbyl Tetraisopalmitate, which is a stable, oil-soluble derivative of Vitamin C. While it is more stable than L-Ascorbic Acid, the general caution regarding Sulphur and Vitamin C suggests potential incompatibility.

Using these products in close proximity in time, even if applied to different areas like your scalp and face, could potentially lead to some degradation of the Vitamin C, particularly the Natural-C Glycol. This is because there might be residual contact or interaction.

To minimize the risk of ingredient degradation, it is recommended to avoid using your Sulphur shampoo/soap and your Vitamin C serums at the exact same time. You could consider using the Sulphur product at a different time of day than when you apply your Vitamin C serum, or on alternate days if possible.

Following this approach should help maintain the effectiveness of both your Vitamin C serums and your Sulphur product.
