Confidence in a Gel Cream Oil-Free Moisturizer has not been tested for use with products containing vitamin C or retinol. We recommended that you gradually introduce one product at a time into your skincare routine and that you patch test potent formulas or product combinations before first use.
You can conduct a patch test by placing a small amount of product onto clean skin on the inside of your forearm. Allow product to fully absorb before layering and monitor reaction on skin, if any. If sensitivity such as redness, burning, or itching occurs, do not use the product or product combination patch tested. Should you have any concerns about mixing or layering new formulas into your skincare routine, please consult your dermatologist prior to use.
