Which hair-removal service is contraindicated for clients using Differin or Renova?

• A. Shaving
• B. Sugaring
• C. Laser hair removal
• D. Waxing

Answer: (D)

Retinoids like Differin and Renova thin the outer skin layer and increase skin sensitivity. When the skin is in this state, procedures that aggressively remove or irritate the surface are risky. Waxing pulls on the surface skin as it removes hair, which can lead to irritation, micro-tears, or burns on retinoid-treated skin—so it’s contraindicated. Shaving doesn’t remove skin layers, so it’s generally safe. Laser hair removal uses heat and light and carries a higher risk of burns or pigment changes on sensitive, retinoid-treated skin, and sugaring is also exfoliating but typically less intense than waxing; however, waxing remains the clearly contraindicated option here.
