One of the lesser-known side effects of liposuction is that temporary acne, folliculitis, or skin dryness may occur after surgery, especially on the face, upper arms, and back.

This is usually not a complication, but a temporary inflammatory reaction based on normal skin anatomy.

1. Hair Follicle Stem Cells Exist in the Superficial Fat Layer

Hair follicle stem cells are present not only in the dermis but also in the superficial subcutaneous fat layer.

During liposuction, this layer is mechanically stimulated by the cannula, which can trigger:

• Micro-inflammation
• Temporary follicular irritation

This reaction may appear as acne or folliculitis on the skin surface.

2. Postoperative Inflammation and Blood Flow Changes Affect Sebum Balance

After liposuction:

• Blood flow and lymphatic circulation temporarily change
• Sebum production becomes unstable
• Keratin turnover is disturbed

This creates an environment where acne-causing bacteria can proliferate, leading to postoperative breakouts.

3. Why Hair May Reappear or Look Darker After Hair Removal

• Dormant hair follicles may shift into the growth phase due to inflammation
• Temporary hyper-perfusion can make hair appear thicker

These changes are usually temporary and reversible.

4. Most Cases Resolve Naturally Within 3–6 Months

As postoperative fibrosis (induration) and inflammation improve, skin conditions usually normalize within 3–6 months without permanent damage.

5. Effective Medical Treatment: Benzoyl Peroxide (Bepio Gel)

When inflammatory acne appears, benzoyl peroxide gel with antibacterial and keratin-normalizing effects is highly effective.

We routinely recommend this medication as part of postoperative skin care when needed.

Conclusion

Post-liposuction acne and skin irritation are usually caused by:

• Mechanical follicular stimulation
• Temporary inflammation
• Transient changes in blood flow and sebum production

These are medically explainable and temporary reactions, and most cases recover naturally with proper care.
