What can stale cuticle removers cause to the nails?

Stale cuticle removers can lead to corrosion and damage to the nails. These products often contain active chemicals that, when left unused for extended periods, can break down and become less effective or even harmful. When applied to the nails or the surrounding skin, stale products may not only fail to effectively remove the cuticle but can also cause irritation or chemical burns, leading to weakened nails and compromised skin integrity. This damage can manifest as brittleness, splits, or peeling of the nails, emphasizing the necessity of using fresh and appropriately stored cuticle removers for both nail health and safety.

The other options do not represent the effects of using stale cuticle removers accurately. Strengthening of the nail or improvement in growth rate are outcomes that generally result from proper care and nutrition, rather than from the use of degraded products. Similarly, while cuticle moisturization is beneficial, stale products are less likely to provide moisture and can actually lead to dryness or irritation instead.
