([International Journal of Cosmetic Science, 2020](https://pubmed.ncbi.nlm.nih.gov/32812663/))

## How to apply

- Use your creamy mask PM routine once a week to start, then increase frequency if your normal skin feels good. Always remember to wear SPF during the day to protect your skin.
- Apply the creamy mask after cleansing and toning, and before your usual moisturizer. This helps lock in all the good ingredients for your skin.
- Smooth an even layer of the creamy mask over your face while avoiding the eye area. Do not rub it in harshly.
- Apply the creamy mask on dry skin since your skin is not sensitive and can handle active ingredients well. Let it sit for the recommended time before rinsing or patting in.
- Always do a patch test before your first use to check for any allergic reactions. Avoid mixing this mask with strong acids in the exact same routine.
