Best Derma Roller Needle Length for Acne Scars in Canada

Excerpt: Not all derma roller needles are created equal. Canadians dealing with acne scars often ask: which size works best? Here’s your complete guide to choosing the right needle length.

Why Needle Length Matters for Acne Scars

Shallow needles (0.25 mm) help with product absorption but won’t improve scars. For collagen stimulation, longer sizes like 0.5 mm–1.0 mm are needed.

Recommended Sizes

• 0.5 mm: Best for mild acne scars and skin rejuvenation.
• 1.0 mm: More effective for moderate to deep acne scarring.
• 1.5 mm: Only recommended in a clinic setting, not at home.

How Often Should You Roll?

Frequency depends on the needle size:

• 0.5 mm: every 2 weeks
• 1.0 mm: every 4 weeks

Safety First

Always sterilize your roller, avoid active acne, and never share devices. Read safety tips here.
