  retinaldehyde cost and concentration

  Posted by hectic000 on March 29, 2023 at 12:34 am

  I’ve been using a retinaldehyde serum that’s stronger than my retinol cream. I like the results so far but it is on the expensive side. I noticed that other retinaldehyde creams and serums online are on the more expensive end as well.

  Has anyone here ever worked on a retinaldehyde product?

  If so, is it in fact a more expensive ingredient to incorporate?

  Also, what concentration is best?

  Thank you 🙂
