It is generally acceptable to utilise a skincare product after it has passed its expiration date. According to Skinacea.com, whether it’s safe depends on a number of factors, including how much time has elapsed, the temperature it was stored at, and the product’s contents.
Do not use the product if it was stored at an unsuitable temperature. The product will be less effective if it contains vitamin C or is a sunscreen. If you distributed the product with your fingers rather than a pump, bacteria may have accumulated; in that case, toss it out. According to Skinacea.com, you should check to see whether the product appears to be suspect, read the packaging labels, or call your dermatologist for further information.
