Have you heard of the "sandwich method" for applying the hot ingredient retinol without side effects?

We all know retinol is good for improving wrinkles, but some people give up on it because of its characteristic stinging sensation and the appearance of flaky skin. I use the sandwich method: moisturizer - retinol (a grain-sized amount) - moisturizer. This method is much less irritating than applying it directly to the skin, while still achieving significant results. Just remember to apply retinol only at night, and be sure to follow up with sunscreen the next morning!
