Why olive-oil soap is the starting point
Olive oil is unusually high in oleic acid and squalene - two molecules also produced by human sebaceous glands. Saponified into soap, it produces a lather that's slow to come up but unusually emollient: it retains some of the oil's lipid-rebuilding character even after the alkaline cook. Customers with very dry skin often keep returning to plain olive-oil soap when other cleansers have stripped them. The trade-off is that olive-oil soap is mildly alkaline (pH around 8-9, like most cold-process bars), which suits most skin types but not everyone - if your skin tightens noticeably even after a brief plain-olive-oil wash, you may do better with a syndet (synthetic detergent) cleanser at skin-neutral pH.
What to add after cleansing
Body oil while the skin is still damp from the shower. The water content of the skin is highest in the first thirty seconds out of the bath; oil applied immediately traps that water under a thin lipid layer, which is the entire mechanism of feeling moisturised. Plain olive oil works; so does our Damascus rose body oil if you want a scent. For face and neck, a richer water-and-oil cream - wild honey, calendula - tends to outlast a pure oil. What to avoid: very long hot showers, harsh exfoliants, alcohol-based toners, and the temptation to apply anything to skin that's been dry-towel-rubbed for several minutes. The order matters.
