My RESIST C15 Super Booster is a different colour than I'm used to. Is it okay to use?
You may notice from time to time that the shade can vary on your C15, especially after use. It can vary from clear to a light yellowish colour. One of the challenges of having an irritant-free line is that we cannot use colouring agents or dyes to ensure a precise, consistent colour from batch to batch. Because of this, there can be colour variations with some of our products.
If your C15 has been open past the 3 month PAO (Period After Opening) time frame, and the color and texture have changed to a dark brown with a thick texture, it is best to replace the product in that case. For more information regarding product expiration dates, please click here.
