The why

Those sudden "where did that come from?" dark spots, sunspots, and hormonal melasma happen because oestrogen dips can make our skin cells sluggish. Cell turnover slows right down—often stretching from a healthy 28 days to nearly 60 days. This means pigmented, dry cells linger on the surface much longer, making your complexion look dull and uneven. Even worse, it means every active serum you apply is sitting on a layer of dead cells instead of reaching live skin. We selected The Go-Between formulation to act as the ultimate supportive bridge between your cleanse and treatment steps. Its 5% Glycolic Acid gently dissolves dead surface bonds, coaxing fresh, bright skin to the surface so your active serums actually land where they can perform.

The How

When: PM (or AM if your skin is well-adjusted to AHAs, always followed by SPF).

Order: Step 02 / The Bridge Step. Apply immediately after your Cleanser (Step 01) and right before your custom Serum (Step 03).

Application: Sweep over clean, dry face and neck using a cotton pad, or press a few drops directly into your skin with your hands. Avoid the immediate eye area. Let it absorb for a moment before applying your serum step so it can actively guide the ingredients deeper.
