44% Carbamide Peroxide Whitening Pen — Professional Take-Home
The LaserGlow 44% CP Whitening Pen is the recommended take-home maintenance product for clients between professional whitening sessions. Carbamide peroxide's gradual hydrogen peroxide release makes it well-suited for home use — effective maintenance without the session intensity of chairside HP gels.
What the 44% CP Pen Is Designed For
The 44% CP Whitening Pen is a take-home whitening maintenance tool — not a replacement for chairside professional whitening. Its job is to slow shade relapse between professional sessions and give clients a convenient, effective maintenance habit that extends the time between full re-whitening treatments.
Carbamide peroxide releases hydrogen peroxide over an extended period as it contacts moisture and breaks down. At 44% CP, approximately 14–15% active HP is released — gradually, over the contact period. This slower release makes CP more appropriate for extended home application than HP gel at professional concentrations. It's tolerable for regular home use in a way that 25%+ HP isn't.
44% CP Pen vs Professional HP Gels — Key Differences
| Factor | 44% CP Pen (This Product) | Professional HP Gels (Chairside) |
|---|---|---|
| Active whitening agent | ~14% active HP (released gradually) | 16%–44% HP (directly active) |
| Speed | Gradual — maintenance/prevention oriented | Fast — visible results in single session |
| Setting | Home use, self-applied | Chairside, provider-administered |
| Gingival barrier | Not required for home maintenance use | Required for 35%+; strongly recommended for 25% |
| Use frequency | 2–3 times per week ongoing | Per appointment schedule |
| Primary purpose | Shade maintenance between professional visits | Active whitening — shade improvement |

How Clients Should Use the 44% CP Pen
- Frequency: 2–3 times per week for ongoing shade maintenance. Not daily — this is a maintenance protocol, not an intensive whitening course.
- Application: Twist the pen to dispense gel onto the brush tip. Apply a thin layer to the facial surfaces of the upper and lower teeth. Do not rinse for 20–30 minutes after application.
- Timing: Apply after brushing, before bed or during a period where eating or drinking can be avoided for 30 minutes.
- Duration: Use consistently as a long-term maintenance habit between professional whitening sessions. Most clients use it for several weeks to months between professional treatments.
- Sensitivity: At 44% CP (~14% active HP), sensitivity is lower than professional chairside HP whitening. If sensitivity is experienced, reduce frequency to once per week.
The CP Pen as a Retail Product for Whitening Businesses
The 44% CP Pen is a natural point-of-sale after every professional whitening session. Positioning it as part of the whitening service — "here's your maintenance pen to keep your results between visits" — frames it as an extension of the service, not an upsell. This approach:
- Increases per-visit revenue with a product the client actually needs
- Reduces the frequency at which clients need full re-whitening sessions (and the corresponding chair time)
- Gives clients a take-home habit that makes them more satisfied with their whitening results long-term
- Creates a recurring product relationship between the client and your practice
44% CP Pen FAQ
Is the 44% CP pen the same strength as the 44% HP dual-barrel gel?
No. These are two different products for two different purposes. The 44% HP dual-barrel gel is a professional chairside whitening gel that delivers 44% active hydrogen peroxide directly at the moment of application. The 44% CP pen contains 44% carbamide peroxide, which releases approximately 14–15% active HP gradually over the application period. Very different whitening intensities, different use settings, and different purposes.
How many uses does the 44% CP pen provide?
This depends on application amount per use. With controlled application — a thin layer on tooth surfaces — the pen provides multiple weeks of 2–3x weekly use. Clients who apply more than needed per session will exhaust the pen faster. The pen is designed for consistent, ongoing maintenance use rather than a one-time intensive course.
Does the CP pen require gingival barrier?
No. The 44% CP pen is designed for home use with self-application. At 44% CP (~14% active HP with gradual release), home application without gingival barrier is the intended use case. This is different from professional HP whitening gels at 25%+ concentration, where gingival barrier is part of the protocol.
When should clients start using the CP pen after professional whitening?
Clients can begin using the CP pen the day after a professional whitening session — after the immediate 24–48 hour post-whitening stain avoidance window. The desensitizing remineralizing gel is the immediate post-treatment product; the CP pen is for ongoing maintenance starting the next day or the following week.
