Condition finder
Browse guides for eczema and dermatitis, fungal and yeast infections, dry or cracked skin, nail and foot problems, red-light use cases and other home-care decisions.
Use this library when you know what you are dealing with (or the symptom pattern you are trying to understand) and want the shortest route to sensible next steps, treatment classes, safety limits and relevant products.
Some problems need clinical assessment rather than home care. The guides highlight escalation points for severe, recurrent, spreading or painful symptoms, eye or genital involvement, and symptoms that are not responding as expected.
Common starting points
These routes begin with the symptom pattern or body site, then connect to the treatment options and safety guidance that apply.
Separate barrier care, anti-inflammatory treatment, trigger control and look-alikes.

Open the Candida guide → 04Match fissure depth and dryness to moisturizers, keratolytics, occlusion and reasons to seek care.
Open the heel guide →Skin barrier & dermatitis
