Are you checking the expiration dates of your cosmetics? I am leaving a record of my skin.

Recently, I've been getting persistent breakouts for no apparent reason. After looking into the cause, it seems an old essence sitting in the corner of my vanity was the culprit. This experience has made me realize once again that no matter how expensive a product is, its ingredients can change and bacteria can multiply if it has been open for a long time. Please make sure to check the expiration date, everyone.

I have now made it a habit to write the opening date on the outside of my cosmetics whenever I open them. I've heard that it is generally safest to use up toners or lotions within 6 months to a year. I think the best way to protect your skin is to boldly throw them away, even if it feels wasteful, if they feel even slightly off or the scent has changed.

Today, to soothe my skin, I am resting with just a light hydrating gel applied, without using anything else. Seeing how much the redness has subsided, it seems that cleansing is necessary from time to time. Going forward, rather than indiscriminately adding more products, I plan to maintain a healthy skin condition by using only fresh and clean products.
