Discover the benefits of Aleppo soap, one of the oldest natural skincare products. Learn about its ingredients, uses, and why it’s a low-impact alternative to conventional soap.
You know that moment when you pick up a bar of soap, flip it over, and count fifteen ingredients you cannot pronounce? Sodium lauryl sulfate. Methylisothiazolinone. Parfum. You put it back.
Now imagine a soap with three ingredients. Olive oil. Laurel berry oil. Water. That is Aleppo soap — and it has been doing the job for roughly two thousand years without adding a single synthetic compound to the formula.
For eco-conscious shoppers who are genuinely trying to reduce the chemical load on their skin and in their bathrooms, Aleppo soap is not a trend to investigate. It is a return to something that was already right.

What Is Aleppo Soap?
Aleppo soap takes its name from Aleppo, the ancient Syrian city where it has been produced since at least the early medieval period — and likely much earlier. Made from Syrian olive oil and laurel berry oil (pressed from the fruit of Laurus nobilis), it is considered by many historians to be one of the oldest manufactured soap formulas in the world.
The production process is traditional: the oils are cooked together in large copper vats over several days using the hot-process method, poured onto a warehouse floor to set, then cut into bars and stored underground for up to a year to cure and mature. During curing, the green bars develop their signature golden-brown exterior — a layer of oxidised chlorophyll that is one of the most immediate signs of authentic Aleppo soap.
Cut a bar open and you find the vivid green interior intact beneath the aged crust. That green is preserved laurel oil. That is where the benefits live.
In December 2024, UNESCO formally inscribed the craftsmanship of Aleppo soap on its Representative List of Intangible Cultural Heritage — recognising not just the product, but the entire tradition of knowledge, skill, and practice that the Sabonji (master soap-makers) carry.
Aleppo Soap: The Two Ingredients That Make It Work
Olive oil is the nourishing base of every Aleppo bar. Rich in oleic acid — a fatty acid structurally similar to human skin’s own sebum — it supports the skin barrier, retains moisture, and does not strip the acid mantle the way sulfate surfactants do. It also produces natural glycerin during saponification, which most industrial soap manufacturers extract and sell separately. Authentic Aleppo bars retain this glycerin, making the soap inherently more moisturising than commercial alternatives.
Laurel berry oil is the active, medicinal ingredient that makes Aleppo soap genuinely different from any other natural bar. It contains lauric acid (antibacterial, directly effective against acne-causing Cutibacterium acnes), linalool (anti-inflammatory, antifungal), 1,8-cineole or eucalyptol (antimicrobial, penetration-enhancing), and beta-pinene (antiseptic). These are not incidental compounds — they are the reason Levantine households have been using this soap to manage acne, dandruff, eczema, and skin infections for centuries before dermatology existed to explain the mechanisms.
The percentage of laurel oil in a bar determines its character. A 5% bar is gentle enough for baby skin and rosacea-prone faces. A 40% bar is a serious tool for persistent dandruff or moderate acne. A 75% bar is the most potent formulation in the traditional range. If you are looking to explore the full spectrum, Avlia’s Aleppo soap collection covers every percentage from 5% to 75%, each made by Syrian Sabonji artisans who relocated to Turkey after the conflict disrupted Aleppo’s production.
Why It Matters for Eco-Conscious Skin Care
The sustainability argument for Aleppo soap is not marketing. It is physics.
A solid bar contains no water — liquid body washes and shampoos are up to 80% water, shipped in plastic bottles around the world. A solid bar needs no preservatives because without water in the formula, there is no medium for bacterial growth. No parabens, no isothiazolinones, no synthetic stabilisers. The formula is inherently stable.
The packaging is cardboard or nothing. The ingredients — olive oil and laurel berry oil — come from perennial trees that have grown in Mediterranean and Levantine soil for millennia with minimal agricultural intervention. What rinses off the bar and goes down the drain is, essentially, a dilute solution of saponified plant oils. Fully biodegradable. Nothing that persists in waterways.
One bar typically replaces three to four liquid products: body wash, face wash, shampoo, and in some cases shaving gel. For anyone genuinely trying to reduce plastic in the bathroom without compromising on skin results, Aleppo soap is the most practical single swap available.
Who Should Try Aleppo Soap
Aleppo soap is not exclusively for people with skin conditions, but it does help with most of them. Here is how the different percentages map to different needs:
Dry, sensitive, or eczema-prone skin — start with a 5% or 10% bar. The formula is predominantly olive oil, gentle enough for the most reactive skin, and free of every common synthetic trigger. The anti-inflammatory compounds in even a small amount of laurel oil can help calm chronically irritated skin without aggravating it.
Combination or normal skin — a 16% bar is the ideal everyday option. This is the balance point: enough laurel oil for real antibacterial and antifungal cleansing, enough olive oil to keep the bar nourishing rather than stripping.
Oily skin, acne, or scalp conditions — move toward 30% to 50% laurel. These bars are where the antibacterial and antifungal properties are most therapeutically meaningful. For dandruff specifically, a high-laurel bar applied directly to the scalp with a two-minute contact time targets the Malassezia yeast responsible for flaking more directly than most conventional medicated shampoos.
The key technique that applies to every use: build lather between wet palms first, then apply the foam to skin. Never rub the bar directly on the face or body. This protects delicate skin and produces a better, more evenly distributed lather.
What Real Aleppo Soap Looks Like (So You Can Spot the Fakes)
Since the Syrian conflict after 2011 reduced Aleppo’s production dramatically — from over 120 factories to fewer than 20 — counterfeit and imitation bars have flooded the market. Many are palm oil bases with synthetic laurel fragrance. They look similar. They deliver none of the genuine benefits.
Authentic Aleppo soap has three to four ingredients on the INCI label: Sodium Olivate, Sodium Laurus Nobilate, Aqua, and optionally Laurus Nobilis Fruit Oil. No parfum. No sodium palmate. No more than four items on the list. The bar has a golden-brown exterior and a green interior when cut. The scent is earthy, herbal, and slightly resinous — not floral, not sweet, not chemical.
Brands like Avlia work directly with Syrian Sabonji artisans who resettled in Turkey, preserving the same hot-process technique, the same ingredient ratios, and the same hand-stamping tradition. Full ingredient transparency, authentic provenance, and a range broad enough to serve every skin type.
The Bathroom Swap Worth Making
Most sustainable bathroom swaps ask you to sacrifice something — lather, performance, convenience, or scent. Aleppo soap asks for none of these compromises. It lathers differently from sulfate soap (creamier, denser, more skin-adhesive), but it lathers well. It performs measurably better than commercial soap for most skin conditions. It lasts four to eight weeks in daily use on a draining soap dish. And it smells, authentically, of two thousand years of craft.
The eco-conscious bathroom does not need to look like a sacrifice. It just needs the right bar.
