Please Do Not Use Day Creams With Retinol
Retinol should never be used during the day according to WebMD and what I learned in studying for my Cosmetology degree. Web MD says "Retinol causes skin turnover and the new skin is delicate and should NOT (emphasis addded) be exposed to the sun. That is why Retinol should only be found in products intended for night use. They break down when exposed to the sun and air. That's why Retinol-containing products should always come in a pump or tube with a tight fitting cap. Once opened, these products do not keep well and should be used. ...in daytime products, Retinol will have the OPPOSITE (emphasis added) effect and actually make skin age faster because it (the skin) is more susceptible to the sun no matter the amount of SPF protection promised on the product. A good rule of thumb is never buy a product with SPF and retinol in its list of ingredients. To learn more about this, Google should Retinol be used during the day.
