Dull isn’t a skin type. It’s a reading.
Skin can look flat for several reasons. A slow surface, low water, or a barrier that’s been pushed too hard. Each one calls for something different.

Skin concerns · Dullness
Skin can look flat for several reasons. A slow surface, low water, or a barrier that’s been pushed too hard. Each one calls for something different.
In short
Skin looks dull when old surface cells linger, water is low, or the barrier is stressed. A Vernier reading works out which applies to you. The plan then prepares the surface without stripping it.
The science
The surface of your skin renews in a cycle of roughly four to six weeks. When old cells linger, light scatters and skin looks flat.
Low water does the same. So does a stressed barrier, even when it briefly looks bright.
A flush from strong acids photographs as glow. It isn’t. It’s irritation, and it needs another hit to keep the look.
For the surface of your skin to renew.1

Your reading
Photos show what’s visible. Questions fill in what a camera can’t see. For dullness, these matter most.

What usually waits
Acid cleansers wait if your skin stings or flushes. In our sample reading, the lactic cleanser was held back for exactly that reason.
What to expect
Questions
Because a flush isn’t a result. Over-exfoliating opens the barrier, raises water loss and leaves skin reactive. Your plan prepares without stripping.
We won’t promise one. Early change is usually comfort first. The surface takes four to six weeks to turn over.
