BY WISHTREND FAQ
Everything you need to know about expert K-beauty by Wishtrend.
Which BY WISHTREND product should I start with?
If you are new to actives, start with Mandelic Acid 5% Skin Prep Water: a gentle exfoliation, well tolerated. For more experienced skin seeking radiance and anti-mark effects, Vitamin C 21.5% Advanced Serum is the reference.
Who is mandelic acid for?
Mandelic acid is a large-molecule AHA, so it’s gentler than glycolic acid. It’s suitable for sensitive skin wanting a mild exfoliation, skin with imperfections, and skin new to actives.
Is Vitamin C 21.5% too concentrated?
It’s a high concentration, reserved for experienced users. If you’ve never used vitamin C, start with a 5-10% product before moving up to 21.5%. Introduce it gradually (once every two days, then daily).
What is the connection with Klairs?
Wishtrend, the Korean group behind BY WISHTREND, is the same one that launched Klairs. BY WISHTREND focuses on more expert formulas, with higher concentrations. Klairs remains the minimalist and accessible entry point.
Can mandelic acid and vitamin C be combined?
Yes, but not at the same time. Instead, use mandelic acid in the evening and vitamin C in the morning, alternating. And don’t forget SPF during the day, essential with these two actives.
Are BY WISHTREND products on Ma Petite Corée authentic?
Yes, 100%. Ma Petite Corée has been based in Seoul since 2017 and sources directly. Every product is new, sealed, and shipped from Korea, with no customs fees charged to you in the EU.
