Bio-Oil Skincare Oil (Original) 60ml 7 / 10

The full breakdown

A fragranced mineral-oil scar and stretch-mark oil best confined to dry, non-acne skin. A brand-commissioned proDERM Institute RCT reported 66% of subjects showing significant scar improvement after 2 weeks, rising to 92% at 8 weeks.

Ingredient breakdown

• Paraffinum Liquidum
  Limited evidence

  Commonly used as an occlusive emollient to reduce transepidermal water loss. Clinical studies of petrolatum (the closely related semisolid mineral-oil derivative) show real, measurable skin barrier and hydration effects, and it remains a benchmark comparator in dermatology research for occlusive moisturizers — evidence specific to the liquid form (paraffinum liquidum) itself is more limited.

• Retinyl Palmitate
  Moderate evidence

  Commonly used as a milder retinoid option, often combined with in-office procedures like microneedling for enhanced results. A preliminary split-face placebo-controlled study found 5% retinyl palmitate oleogel combined with microneedling improved acne scar appearance and patient quality of life versus microneedling with placebo alone.

• Calendula Oil
  Moderate evidence

  Wound-healing and skin-soothing botanical -- randomized clinical trials show Calendula-based preparations can speed epithelialization of acute hand wounds and, combined with low-level laser therapy, support diabetic foot ulcer healing and pain relief. Irritancy and allergic contact dermatitis have been reported in sensitized individuals, particularly with medicinal-strength use.
