How it works
An ampoule sits at a specific point in a layered Korean routine, and its texture is built for that placement: Micro-Active Brightening Ampoule 15ml is formulated with a brightening focus, which decides both how it feels going on and which step it follows. Applying it while the previous step is still slightly damp helps a water-forward ampoule absorb rather than sit on the surface, while a richer ampoule is meant to follow once lighter layers have already sunk in. Used consistently at the same point in the routine, rather than skipped some days and doubled up on others, is what lets a brightening formula do its job the way it is designed to. Patting rather than rubbing it in reduces friction on skin and helps the formula settle evenly before the next step goes on. Waiting a short moment between layers, rather than piling every step on at once, gives each one time to absorb on its own.
Key benefits
- Ampoule formulated with a clear brightening focus rather than a vague all-purpose claim
- Texture matched to its place in a layered Korean routine
- Absorbs into the layer before it rather than sitting on top unabsorbed
- Sized for consistent daily use rather than an occasional treatment
- Part of su:m37's wider routine, built to layer with the brand's other steps
Where does this ampoule go in my routine?
Apply Micro-Active Brightening Ampoule 15ml after cleansing and toning, then follow with the next layer in your routine from thinnest texture to thickest. A brightening-focused ampoule generally sits earlier in the lineup so lighter ingredients can absorb before a heavier moisturizer seals everything in.
How much should I use per application?
A small amount, enough to cover the face and neck in a thin, even layer, is enough for most people. Using more than that does not speed up how the formula works, it just uses the 15ml bottle faster.
Can I use this both morning and night?
Yes, Micro-Active Brightening Ampoule 15ml is formulated for twice-daily use, though anyone with reactive or sensitive skin can start once daily and build up to twice as their skin adjusts.
How long before I notice a difference?
Consistent use at the same step in your routine over several weeks is what lets a brightening formula show up in how skin looks and feels, rather than a single application.
How do I confirm this bottle is the authentic Korean-market formula?
Check the batch code and Korean-language text on the packaging against su:m37's own listings. This is sourced and warehoused specifically as the Korean-market formula, and never a US-shelf substitute.

How to use
- Apply after cleansing and toning, patting or smoothing a small amount evenly over the face and neck. Follow with the next step in your routine, layering thinnest to thickest. Use morning and night unless your skin runs sensitive, in which case start with once daily.
Worth knowing
- Introduce gradually if your skin is reactive, starting once daily before moving to twice
- Patch test on the inner arm first if you have known sensitivities
