Quick Answer: Full-grain leather should be conditioned once or twice a year at most, or whenever it looks noticeably dry.
Full-grain leather doesn’t need much conditioning—its strength and beauty come from the natural oils already preserved during tanning. For most climates, once or twice a year is more than enough, and many customers find they never need to apply anything at all. The best conditioner is regular use: the oils from your hands gradually enrich the leather and build a deep patina. If your leather looks noticeably dry, you can apply a thin layer of leather balm or Venetian cream with a soft cloth, let it absorb overnight, and buff lightly. Avoid saddle soap or heavy waxes, which can over-condition or change the texture.
