Will SMP Fade Blue? Pigments, Skin Types & Sun Myths
Scalp micropigmentation (SMP) used to get a bad reputation for “turning blue,” but that outcome is mainly linked to outdated inks and poor technique. Modern SMP pigments are engineered to stay true-to-tone. In this article, we explain why colour changes happened in the past, how your skin tone influences perception, and what you can do to keep your SMP looking natural.
Why old SMP and tattoos turned blue
- Inferior pigments: Early practitioners often used tattoo ink or cheap pigments with heavy metals that oxidised to a blue/green hue over time.
- Depth of placement: If pigments are implanted too deep, they sit in the dermis and get filtered by collagen, making them appear bluish. Proper SMP is placed in the upper dermis to avoid this.
- Sun exposure: UV light can break down certain pigments and make underlying tones more visible. Without sun protection, fading and colour shifts happen faster.
Modern SMP pigments stay colour-true
- Reputable clinics use carbon-based, cosmetic-grade pigments designed specifically for SMP. These pigments are organic and stable; they heal to a soft charcoal tone that mimics stubble.
- Pigments are diluted and layered to match your skin tone and existing hair colour. A practitioner blends shades for a natural look.
Skin tone & perception
- On lighter skin, any pigment will contrast more, so it’s crucial to choose the correct shade and density.
- On darker skin, under-depositing can make dots look grey; correct dot size and layering help avoid this.
- Your skin undertone (cool vs. warm) also affects how SMP appears. Experienced artists adjust pigments accordingly.
How to keep your SMP looking sharp
- Follow aftercare – avoid heavy sweating, swimming and sun for 7 days and don’t pick scabs. Use fragrance-free moisturiser to aid healing.
- Wear SPF daily – apply broad-spectrum SPF 30+ on your scalp whenever it’s exposed. UV damage is the biggest cause of premature fading.
- Schedule top-ups – most clients need a refresh every 2–5 years to maintain density and tone.
Myth-busting: Will the sun turn my SMP blue?
No. If SMP is done correctly with modern pigments, sun exposure will fade the pigment but won’t change its colour to blue. However, UV rays do break down pigment faster, so always protect your scalp.
