Frequently asked questions
Everything you need to know about Sparkl: how the products work, what's in them, and how to get the best from your routine.
What is the difference between the two products?
Stain Removal Polish helps refine everyday surface stains over time. Glow Serum uses violet colour-correcting pigments to temporarily balance the appearance of yellow tones. Use either product alone or pair them together for both refinement and colour correction.
Can I use both products together?
Yes. Use Stain Removal Polish first to refine surface stains, then use Glow Serum to give your smile a brighter-looking, colour-corrected finish.
How often should I use Stain Removal Polish?
Use as directed on the product packaging. It is designed to fit into a regular oral care routine and deliver progressive results with consistent use.
How often should I use Glow Serum?
Use Glow Serum whenever your smile needs a brightness boost, including before photos, meetings, nights out or special occasions. Follow the directions on the packaging.
Will these products cause sensitivity?
Both products are peroxide-free and designed with comfort in mind. Individual experiences can vary, so stop using the product if irritation occurs.
Can I use them on veneers, crowns or composites?
Glow Serum may change how yellow tones appear but cannot permanently whiten dental restorations. Product suitability can vary, so follow the packaging directions and speak to a dental professional if you are unsure.
