Enlighten Evolution guarantees a Vita B1 shade (the lightest natural shade) for every patient — no other system makes that promise. Philips Zoom is the fastest, with results in 90 minutes. Boutique is the most affordable, fully take-home option. The right choice depends on your starting shade, sensitivity tolerance, budget and timeline.
Boutique Whitening is a take-home system using custom-fitted trays loaded with carbamide peroxide gel (10–16% strength). You wear the trays at night for 2–3 weeks. It is the gentlest and most affordable option. It is not the fastest.
Philips Zoom is an in-clinic light-activated system using 25% hydrogen peroxide gel and a blue LED to accelerate whitening. Three 15-minute applications in a single 90-minute visit. It is the fastest single-visit treatment available. It is not the system with the lowest sensitivity rates.
Enlighten Evolution is a hybrid system: 2 weeks of take-home gel followed by a 1-hour in-clinic “power” appointment. Developed by Enlighten Smiles, it’s the only system in the UK that guarantees the result.
| System | Average shade improvement | Final shade guarantee | Treatment duration |
|---|---|---|---|
| Boutique take-home | 5–8 Vita shades lighter | None | 2–3 weeks |
| Philips Zoom in-clinic | 4–6 Vita shades lighter | None | 90 minutes single visit |
| Enlighten Evolution | Vita B1 (lightest natural shade) | Yes — money-back if not B1 | 2 weeks + 1 hour in-clinic |
According to Enlighten’s published clinical data, 95%+ of treated patients reach B1 shade. The remaining 5% are typically tetracycline-stained or have heavy intrinsic discolouration that no peroxide system can fully address.

Enlighten is the most expensive but it’s the only system that guarantees a specific final shade. Boutique and Zoom are not inferior — they’re priced honestly without that guarantee.
According to a 2024 systematic review in the British Dental Journal:
Enlighten’s lower sensitivity rate reflects the gel’s lower peroxide concentration and longer treatment time, which gives the tooth time to remineralise between applications.
For sensitive patients, see teeth whitening for sensitive teeth for a tailored approach.
| Patient profile | Best system | Why |

| Budget-conscious, mild discolouration | Boutique | Most affordable; good results |
