Best PDRN Serums, Eye Balm Sticks, and Manual Facial Tools (2026): Firming, Eye Care, and Contouring Tested

KAHI Blemish Ampoule and Eye Balm Stick occupy different places in a skincare routine. Choose between them by the step you want to add: a liquid serum treatment or a portable balm for selected areas. This comparison uses KAHI’s published product information; it does not report independent testing.

Blemish Ampoule: a serum-step option

KAHI positions its Blemish Ampoule for hydration and the appearance of uneven tone. The brand highlights niacinamide, idebenone, a salmon complex and several forms of hyaluronic acid. Its ingredient list includes sodium DNA.

The listing’s 200,000 ppm figure refers to vitamin water, not PDRN concentration. KAHI directs shoppers to use the ampoule at the serum step and permits two or three layers on dry areas, while advising against excessive application.

Eye Balm Stick: a portable, targeted format

The Eye Balm Stick offers a solid format for the skin around the eyes and other selected areas. KAHI highlights licorice extract, rice germ oil, hydrolyzed collagen and adenosine, and describes cosmetic benefits for hydration, radiance and the appearance of fine lines.

The brand recommends a thin layer around the under-eye area and says the stick can be reapplied during the day, including over makeup. Keep it on external skin and avoid direct contact with the eyes. Both product listings advise a patch test for sensitive or reactive skin.

Which fits your routine?

Choose the ampoule if your priority is a serum step. Choose the balm if your priority is a compact applicator for selected dry areas and daytime touch-ups. You do not need both simply because their ingredient stories overlap.

Check current listings and packaging for directions, ingredients and availability before ordering. Manufacturer benefit claims do not establish how either product will perform on your skin, and neither format is universally better.
