Question

I am using a skin cream that contains Bismuth Subnitrate and Salicylic Acid. I have a few questions about its effects:

  • Does this cream cause skin thinning, especially with long-term use?
  • Is the whitening effect from Bismuth Subnitrate permanent, or will my skin revert to its original color if I stop using it?
  • Are there other potential long-term side effects or precautions I should be aware of, such as increased sun sensitivity?

Answer

Based on the information provided:

  1. Regarding skin thinning: Yes, both Bismuth Subnitrate and Salicylic Acid can potentially cause skin thinning when used regularly, especially at high concentrations or with long-term use. Bismuth Subnitrate is a bleaching agent that can irritate the skin, and Salicylic Acid is an exfoliant. Using a cream with both ingredients regularly is likely to have negative long-term effects, including skin thinning and increased sun sensitivity.
  2. Regarding Bismuth Subnitrate and skin whitening: Yes, Bismuth Subnitrate is a "bleaching" or whitening agent. It can make the skin appear whiter quickly, but this effect is temporary and the skin will return to its original state after stopping use.

It's important to be cautious, particularly with unreliable brands, as concentrations might exceed safety limits. If you continue using such a cream, high SPF sunscreen is essential daily, as your skin will be thinner and more susceptible to sun damage.
