Why repeated exposure matters

In product safety, dose and frequency matter more than a single contact.

Repeated exposure means the skin and immune system are contacted again and again, often in small amounts that seem insignificant on their own. Over time, this repeated contact increases the likelihood of the body recognising certain substances as a threat.

In professional nail services, exposure is rarely accidental or one-off. It is:

• frequent
• cumulative
• part of daily work

This makes repeated exposure a real risk factor, not a theoretical one.

How this applies in practice: 

Repeated exposure can come from:

• uncured or under-cured product contact
• residue on tools, brushes, or gloves
• product transfer to surrounding skin
• long-term handling over months and years

Each contact adds to the overall exposure load.

Why this matters professionally

Once the immune system becomes sensitised, reactions can occur at much lower levels than before. What was once tolerated may no longer be.

This is why professionals focus on risk reduction, not just reaction management.
