@CaptainFlintlockFinn are those resin support marks? If so you could try reorienting your model to reduce the number of supports needed. Possibly experimenting with the number, spacing and thickness may get better results. I’m no expert but have found it helps sometimes.
@Piecemakers3Dprints @CaptainFlintlockFinn as a one time chemist I’d agree that there is a real possibility some trace materials in the resin causing some harm in prolonged contact. The resin may be set but could potentially leach some of the other materials such as unreacted ingredients, catalysts etc. In the same way that cheap jewellery can release alloying metals that cause irritation. A dermatologically safe varnish seems a sensible call.
