SEOUL, SOUTH KOREA, November 12, 2026 /EINPresswire.com/ -- EQQUALBERRY, the K-beauty longevity skincare brand, today announced its Black Friday and Cyber Monday (BFCM) campaign on Amazon US, offering up to 65% off seven bestsellers spanning serums, creams, a toner and toner pads. The event runs from Nov. 19 through Nov. 30, 2026.

Leading the lineup is the NAD+ Peptide Boosting Serum, 40% off at $14.99. The serum is formulated with NAD+ and 14 peptides to support visibly firmer, more resilient-looking skin.

The Vitamin Illuminating Serum, a #1 Amazon Best Seller in Facial Serums, is also 40% off at $14.99. The brightening serum combines 40% acerola fruit water with niacinamide and arbutin to visibly fade dark spots and boost radiance. Rounding out the serum trio, the Bakuchiol Plumping Serum, a gentle retinol alternative for sensitive skin, pairs 0.5% plant-derived bakuchiol with 13 types of peptides and ceramides to refine the look of pores and smooth fine lines and is also 40% off at $14.99.
