01 · The buyer decision
One serum for every colour of mark
A shopper with healed breakouts rarely has one kind of mark. Some are still red, some have turned brown, and some look yellow and dull. At a pharmacy counter in Poland or the wider Central and Eastern European market, she wants one serum that covers all of them, and she wants it gentle enough for daily use.[1]
By Wishtrend Mandelic Acid Dark Spot Glow Serum is built for exactly that question. It pairs mandelic acid with Clear Bubble Capsules of glutathione and vitamin C derivatives to correct all three colours of dark spots.[1]
02 · Proof
One mandelic acid serum for red, yellow and brown dark spots, tested on 22 adults
The brand ran a clinical study at Global Medical Research Center in 2025 with 22 subjects aged 20 to 39 who had dark spots, post-inflammatory marks and problematic skin. The study covered both inner and surface hyperpigmentation and troubled-skin soothing.[1]
Mandelic acid is a larger alpha hydroxy acid, which is why the line is positioned for daily turnover care rather than a weekly peel. The capsules add the brightening step in the same serum.[1]
03 · Early shopper response
Shoppers describe what your staff can sell
Shoppers who buy the serum alongside the mandelic acid patches describe a gentle feel and a matte finish, the two points a pharmacist can repeat at the counter.[5]
- “Absorbs quickly, and leaves it radiant yet matte.” “The serum feels gentle on the skin, absorbs quickly, and leaves it radiant yet matte, no greasy finish at all.” and**** · Jolse, September 2025 [5]

06 · Display and training
How to sell it in one line
Shelve the serum in the blemish and dark spot bay, next to spot patches. The counter line is simple: "One serum for red, yellow and brown marks."[1]
Train staff to ask one question: is the mark still red, or has it turned brown? Either answer leads to the same serum, which keeps the recommendation short.[1]
