Whatever floats your boat...
after having a rash from the first face mask ever used, took 2 weeks to heal ..so gentle facial with 0.25 cosmetic microneedle and no reaction, nothing on face but homemade serum. still only using Peptides and HA. fearful of niacinamide or Vitamin C for face yet. after a lifetime of avoiding ANYthing on the face, this process has to go slow because of my CT defect effecting the skin and my recent reminder of my allergic tendencies.
