The Net Sponge Is Not a Bleach. Over-Scrubbing Is How Bodies Collect PIH.

A sapo on wet skin a few times a week can lift scale. Daily grinding under SA sun is how shoulders and thighs pick up brown lattice marks.

Key takeaways

• The net is a physical exfoliant, not a pigment treatment.
• Skip the face, active eczema, inflamed acne and fresh bites.
• Two or three gentle wet passes a week plus cream beat a daily sanding.
• Sun on freshly abraded shoulders is how PIH sets for a season.
