Yes! Parallel’s phage serums are safe to use with other products. In fact, phages are known to augment the effects of several active skincare agents, such as Vitamin C, Retinol, and Niacinamide.
However, we recommend to not concurrently apply our phage serums with benzoyl peroxide, tea tree oil, colloidal silver, or denatured alcohol. These products are known to deactivate phages. If you are unsure about the compatibility of your product, please write to us at hello@parallelhealth.io.
