Episode notes
How Nail Polish Is Engineered
- Nail polish is built from polymers, plasticizers, pigments and solvents to form a flexible glossy film on the nail.
- The solvent evaporates after application, leaving a balanced film whose properties depend on polymer ratios and additives.
Always Use Base And Top Coats
- Use a base coat to improve adhesion and smooth ridges, then a top coat to add hardness and UV protection.
- Applying base and top coats properly helps polish last longer and prevents colour transfer to the nail.
Ingredients List Hides The Real Story
- You generally cannot judge a polish's performance from the ingredient list because ingredient ratios are not disclosed.
- Brand reputation, application technique and brush quality often determine real-world results more than ingredient names alone.
