Tattooing directly over moles is strongly discouraged. Raised moles create an uneven surface, which can affect how ink sits in the skin and lead to patchy results. More importantly, covering a mole can make it difficult for your client to notice any changes in its shape or color, which are important signs for monitoring skin cancer and skin health.
Stretch marks are a type of scar tissue formed when the skin stretches quickly due to growth, pregnancy, weight changes and are a natural bodily change. They appear as streaks with a different texture from surrounding skin, which can influence how the ink settles.
Stretch-marked skin is thinner and often more sensitive, tattooing over it requires extra care. Avoid working on fresh stretch marks, but healed ones can be tattooed successfully with the right approach:
-
Ink and Shading: Stretch marks may absorb pigment unevenly. Shading techniques can soften this effect and create a smoother appearance.
-
Styles That Work Best: Watercolor, abstract, and illustrative designs are especially effective since they are more forgiving of textural variations.
Scars come in many forms and each needs to be treated differently:
-
Keloid: Raised, expanding scars. Risky to tattoo, as additional trauma may worsen them.
-
Hypertrophic: Raised but confined to the original wound area.
-
Atrophic: Sunken scars such as acne or chickenpox marks.
-
Surgical or Burn Scars: Larger areas with altered sensitivity and texture.
-
How old is the scar or stretch mark?
-
How has it healed from past injuries or tattoos?
-
Are there ongoing skin sensitivities?
-
Monitor Carefully: Advise them to watch for signs of inflammation, infection, or blowouts.
-
Tailored Aftercare: Suggest gentle healing products and make sure your customer is extra careful when healing.
-
Plan for Follow-ups: Be clear that some areas may need touch-ups due to pigment rejection or uneven absorption.
-
Avoid tattooing over moles that are changing in shape or color.
-
Wait until scars are fully healed, flat, and stable.
-
Postpone work if the client has active skin conditions like eczema, psoriasis, or rashes.
Tattooing over moles, scars, and stretch marks is more than just technical skill, it’s about respecting the personal stories behind each client’s skin. By asking the right questions, practicing patience, and adjusting your techniques, you can create tattoos that not only look incredible but also empower your clients in meaningful ways.
