WellaWhite vs PearliPen: which one fits you?
Both promise brighter teeth at home without peroxide, according to their brands, but they fit very different routines. WellaWhite is a sit-down session with a light mouthpiece and molded trays, while PearliPen is a pocket pen you paint on and leave for a few minutes.

Our verdict
WellaWhite is a complete kit: a cordless mouthpiece with blue and red LEDs, moldable trays you shape in hot water, whitening gel in pen applicators and a printed shade guide. You load the tray, bite down, switch on the light and wait 15 to 30 minutes, once a day. The brand says the gel is peroxide-free and promises up to 9 shades whiter teeth, though it doesn't publish the gel's ingredients. Prices start at $59.00 a kit on the five-pack.
PearliPen keeps it small: three 3 ml twist-up pens per pack, each with a brush tip. You paint a thin layer on each tooth, wait 30 seconds before closing your mouth and skip food and drinks for 15 to 20 minutes, twice a day for one to two weeks. Its listed ingredients, silica, sodium phytate and mint leaf extract, polish and loosen surface stains rather than bleach, which makes it a good fit for keeping coffee and tea stains in check. Prices start at $25.50 a pack on the four-pack.
Neither has independent buyer reviews yet, and neither brand has published a trial of its own product, so choose the routine you'll actually keep. Research on whitening points to the gel, not the light, doing most of the work, so WellaWhite's real appeal is a timed, hands-free session, and PearliPen's is a quick touch-up you can carry in a bag. Neither is meant for crowns or veneers. Both sell one-time orders with shipping added at checkout. Returns: WellaWhite, 30-day returns (unused); PearliPen, 30-day returns (unopened), so keep spare kits or pens sealed until you know you like the routine.
If you like the idea of a timed session on the couch, with a shade guide to track progress, start with WellaWhite. If you want a small, inexpensive touch-up between dental cleanings, PearliPen is the one to look at.
