This is SOME BY MI's daily retinol mask pack, 30 sheets packaged in a jar with 350ml total essence. Daily retinol use from sheet masks is a Korean innovation that enables consistent active exposure without requiring application technique decisions each night. The low-concentration daily formulation delivers retinol in a buffered environment that most users tolerate well. At $56.16 for 30 masks ($1.87 per mask), this is remarkable value for daily retinol application, well below the per-night cost of a retinol serum.
The "daily" positioning is critical to understand. This isn't the same formulation as treatment-tier retinol masks; those are weekly. Daily retinol is calibrated for everyday use at gentle concentration, which means slower but more consistent results with less irritation risk. For users who've struggled with retinol serum tolerance, the daily mask format often works where direct serum application doesn't.
Retinol at daily-use concentration (typically 0.05 to 0.1% encapsulated) accelerates cellular turnover and stimulates collagen production. Supporting ingredients (hydration, niacinamide, centella typically) buffer irritation risk. The daily sheet mask format delivers consistent exposure without the application variability of serum routines. Over 8 to 16 weeks of daily use, expect smoother texture, fading fine lines, more even tone, and improved overall skin quality.
Use PM only (retinol creates photosensitivity). After cleansing and toner, remove one mask from the jar. Apply to face, press for full contact. Leave 10 to 15 minutes. Remove and pat remaining essence into skin. Don't rinse. Follow with moisturizer.
Use daily if tolerated. Start with 3 to 4 times weekly for the first 1 to 2 weeks to establish tolerance. Always apply SPF diligently the following morning.
At this concentration, no. The formulation is calibrated for daily use. More concentrated retinol serums should still be used at most every other day. The daily mask approach is a deliberate low-and-slow strategy.
Not on the same evening. Choose one: the mask, or a retinol serum. Stacking retinol doesn't accelerate results proportional to the irritation it causes. Pick your format and use only one.
