My skin is sensitive and sometimes reacts to new cleansers — how can I test if this soap is suitable for me?

Because sulphur has a keratolytic (surface-exfoliating) action, even the olive oil buffer may not prevent irritation on very reactive or compromised barriers. Before using it on larger areas, do a patch test: wet the bar, create a small amount of foam, apply it to a discreet spot (jawline, behind the ear, or inner forearm), leave for 15–20 seconds, then rinse. Repeat once daily for three to four consecutive days. Watch for persistent tightness, visible flaking, itching, or redness that lasts more than an hour after rinsing — these signal the product is too strong for your current skin state. If the test area stays comfortable, you can begin the gradual introduction described in the usage FAQ. People with diagnosed eczema, rosacea, or very dry skin should consult a dermatologist before adding a sulphur cleanser, as it may worsen barrier dysfunction.
