When Science Meets Smile Care

A brighter smile has become one of the most sought-after aspects of modern oral care. While many teeth whitening products promise instant results, very few are backed by clinical research. At Purexa, we believe every product should be supported by science—not just marketing.

Our Purple Teeth Whitening Serum and V34 Whitening Strips have undergone a clinical evaluation to assess their effectiveness in improving tooth shade while maintaining healthy gums. The findings provide reassuring evidence that both products deliver visible whitening safely when used as directed.

Why Clinical Studies Matter

Choosing an oral care product should never be based solely on advertising claims. Clinical studies help determine whether a product:

• Delivers measurable results

• Is safe for everyday use

• Maintains oral health while improving appearance

• Performs consistently across different users

The clinical assessment of Purexa Whitening Serum and Purexa V34 Whitening Strips was conducted to objectively evaluate these important factors.

About the Clinical Study

The prospective clinical study evaluated 40 healthy volunteers aged between 18 and 25 years.

Participants were randomly divided into two groups:

Group A

• Used Purexa Purple Teeth Whitening Serum

Group B

• Used Purexa V34 Whitening Strips

Researchers evaluated:

• Tooth shade improvement using the Vita Classical Shade Guide

• Gingival (gum) health using the Löe & Silness Gingival Index

• Results at baseline, during treatment, and after completion of treatment

The study was conducted under ethical approval with informed consent from all participants.

Key Findings

1. Both Products Produced Visible Whitening

The study demonstrated that both whitening systems successfully improved tooth colour.

Results showed:

• Approximately 65% of participants using the Whitening Serum achieved a 1–2 shade improvement

• Approximately 80% of participants using the Whitening Strips achieved a 1–2 shade improvement

These findings indicate that both products effectively brighten teeth, while the whitening strips showed slightly greater whitening performance.

2. Healthy Gums Were Maintained

Whitening should never come at the expense of gum health.

Throughout the study:

• Gingival health remained stable

• Slight improvement in gingival scores was observed

• No significant differences were found between the two treatment groups

• No adverse gingival reactions were reported

This suggests that both Purexa whitening products can be used safely when following the recommended instructions.

3. Safe and Comfortable Whitening

One of the biggest concerns consumers have about whitening products is sensitivity or gum irritation.

The clinical assessment reported:

• No major adverse reactions

• Good patient tolerance

• Safe application throughout the treatment period

This reinforces Purexa's commitment to developing whitening solutions that combine cosmetic improvement with oral health.
