The Royal Balls, are simply a cooling tool on the skin that is meant to be stored in the freezer before use and then apply to the face.
Applying a cold surface to the skin can help the epidermis (the first layer of the skin) tighten, shrink pores, and soothe skin after procedures like chemical peels, waxing, and microdermabrasion. Both Shah and Camkrihan mention that the chilled globes are great for relieving redness and calming inflammation.
The Ice balls also claim to help with migraine pain, but Dr. Shah is skeptical. "Aside from the temporary aid of a cold material, any aid that these orbs could give in relieving migraines would be temporary and not as effective as medication or other FDA-approved treatments for that condition," explains Dr. Shah.
