Which device constricts pores, calms irritation, reduces edema, and also dilates pores, soothes nerves and relaxes muscles?

• A. Hot and Cold Hammer
• B. Lucas Spray Pulverizer
• C. Indirect High Frequency
• D. Iontophoresis

Answer: (A)

Pore size, irritation, edema, nerves, and muscle tension respond to temperature changes. A device that alternates hot and cold uses those effects to address multiple skin concerns. Cold helps tighten the skin, reduce swelling and irritation, and calm nerves. Heat increases circulation, relaxes muscles, and can soften tissue, which can help with overall relaxation of the area. By switching between hot and cold, this tool can constrict pores during the cold phase and then dilate them a bit during the hot phase, while also delivering both anti-irritant and soothing benefits. The other options don’t provide this dual temperature action: a spray pulverizer delivers a mist without temperature modulation; indirect high frequency mainly stimulates nerves and provides warming sensations but isn’t focused on pore contraction/dilation and edema reduction; iontophoresis drives ions into the skin for product delivery and isn’t about dual pore size control or relaxation in the same way.
