Type 1 rosacea is a vascular condition causing persistent redness and visible thread veins, not dirt or bacteria, and needs calming care.

Key takeaways

  • Type 1 rosacea is caused by overreactive facial blood vessels, not bacteria or poor hygiene.
  • Heat, alcohol, spicy food, sun and stress are the most common flare triggers.
  • Gentle, barrier-supportive skincare and daily mineral SPF matter more than active ingredients here.
  • Visible thread veins respond best to in-clinic treatments like IPL or pulsed dye laser, not topical products.
