## What reviewers say

This serum is widely praised as a "skin savior" for dehydrated, dull, and sensitive complexions, with users frequently reporting a "glass skin" glow and improved texture. While it excels at soothing redness and providing lightweight hydration for most, a small minority of users with very dry or reactive skin found it insufficiently moisturizing or experienced breakouts.

## How to apply

- Use your moisturizer twice a day in your AM and PM routines. Apply it daily to help keep breakouts under control.
- Apply after your cleanser and toner, and make sure to use your SPF right after in the morning.
- Gently spread a small amount of moisturizer over your face using soft motions. Let it absorb into the skin for a minute before getting dressed or applying makeup.
- Apply on slightly damp skin to help lock in extra moisture. This keeps your combination skin balanced without feeling heavy.
- Avoid the eye area and do a patch test before your first use. Stop using if you feel any irritation.
