Essential oils like eucalyptus, lavender, or tea tree are commonly added to boiling water during facial steaming.
They release aromatic vapors that can help open pores, cleanse skin, and provide relaxation.
These oils also offer antibacterial or calming effects depending on the type used.
Coconut, sesame, and olive oils are carrier oils better suited for direct application or massage but are not used in steaming water.
Adding these thicker oils to steam may not provide any therapeutic benefit for inhalation or facial pores.
Therefore, essential oils are the best choice for steaming.
