Honey has been applied to skin for at least 4,000 years. Ancient Egyptians used it to treat wounds and skin conditions. Ayurvedic medicine prescribed honey-based formulas for the look of redness and infection. Greek physicians recommended it for burns and ulcers.
Modern science has caught up — and it turns out, they were all right. Honey is one of the most comprehensively studied natural skin ingredients in existence. Here's what we know about how it works, and why raw honey belongs in your soap bar.
What Makes Honey Unique for Skin?
Honey isn't a single compound — it's a complex biological mixture with multiple mechanisms of action working simultaneously on skin:
1. Natural Antimicrobial Activity
Honey's antimicrobial properties come from several sources working together:
- Hydrogen peroxide — produced enzymatically by glucose oxidase when honey contacts moisture; creates a slow-release antimicrobial environment
- Bee defensins (defensin-1) — antimicrobial peptides produced by bees that inhibit bacterial growth even in hydrogen peroxide-free honeys
- Low pH (3.2–4.5) — most bacteria cannot thrive in honey's acidic environment
- Low water activity — honey's high sugar concentration draws water out of bacterial cells via osmosis, preventing their growth
- Methylglyoxal (MGO) — particularly high in Manuka honey; potent non-peroxide antimicrobial activity
A comprehensive 2012 review in the Asian Pacific Journal of Tropical Biomedicine confirmed honey's antibacterial activity against a wide range of organisms including Staphylococcus aureus, E. coli, and Pseudomonas aeruginosa.
2. Humectant (Moisture-Attracting) Properties
Honey is hygroscopic — it naturally draws moisture from the surrounding environment and holds it. This makes it an exceptional humectant in skincare: a substance that attracts water vapor from the air and binds it to the skin surface.
This is why skin washed with honey-containing soap often feels noticeably more hydrated than skin washed with plain soap. The honey residue left after rinsing actively pulls moisture toward the skin surface.
3. Soothing-feel Effects
Multiple studies have documented honey's ability to reduce skin the look of redness:
- Honey contains flavonoids and phenolic acids (kaempferol, quercetin, caffeic acid) with demonstrated soothing-feel activity
- A 2014 study in the International Journal of Molecular Sciences showed honey extract inhibited NF-κB — a key regulator of inflammatory response in skin
- Topical honey application has been shown to reduce erythema (redness) and swelling in multiple clinical trials
4. Antioxidant Protection
Honey is rich in antioxidants including flavonoids, phenolic acids, vitamins C and E, and carotenoids. These compounds neutralize free radicals — unstable molecules generated by UV exposure, pollution, and normal metabolic processes that damage skin cells and accelerate aging.
A 2009 study in Food Chemistry documented significant antioxidant activity in raw honey, with darker varieties (buckwheat, Manuka) showing higher antioxidant capacity than lighter ones.
5. Wound Comforting and Skin Repair
Perhaps honey's best-documented skin benefit is wound comforting. Clinical research has shown:
- Honey stimulates the proliferation of keratinocytes (skin cells responsible for barrier repair)
- It promotes angiogenesis (formation of new blood vessels that supply comforting tissue)
- It reduces scarring by modulating collagen deposition
- Thoughtfully made Manuka honey (Medihoney) is FDA-cleared for wound care and is used widely for burns, diabetic ulcers, and surgical wounds
Why Raw Honey vs. Processed Honey Matters
Commercial honey is often ultra-filtered and heated to prevent crystallization. This processing degrades many of honey's most beneficial compounds:
- High heat destroys glucose oxidase (eliminating hydrogen peroxide production)
- Fine filtration removes pollen, bee defensins, and other bioactive compounds
- Ultra-processing strips flavonoids and phenolic acids that contribute antioxidant and soothing-feel activity
Raw honey retains all of these compounds intact. At NoOSky, we use raw honey specifically to preserve the full spectrum of its skin-beneficial properties.
How Honey Works in Cold Process Soap
Adding honey to cold process soap is a delicate art. A few important things happen:
- The sugars in honey (fructose and glucose) cause an acceleration in saponification — they interact with lye to generate heat, which must be controlled carefully to prevent "volcanoing" (overheating)
- Honey sugars contribute to a more luxurious, bubbly lather — the monosaccharides boost the foaming action of the soap
- The humectant properties are largely preserved through the saponification process, meaning honey soap genuinely conditions skin more than plain soap
- A mild natural honey scent remains in the finished bar from raw honey's volatile aromatic compounds
Which Skin Types Benefit from Honey Soap?
- Dry or dehydrated skin — the humectant action pulls moisture to the skin surface
- Blemish-prone skin — the antimicrobial properties help control blemish-prone skin-causing bacteria without harsh chemical antibacterials
- Sensitive or reactive skin — honey's soothing-feel flavonoids soothes the look of redness
- Aging skin — antioxidants protect against environmental damage; wound-comforting properties support cellular turnover
- Combination skin — honey balances without over-drying or over-conditioning
Frequently Asked Questions
Will honey in soap make my skin sticky?
No. The concentrations of honey used in soap are low enough that any residue rinses clean. What remains is a very thin humectant film — imperceptible to touch but effective at holding moisture.
Is honey soap suitable for oily skin?
Yes. Despite being a humectant, honey is non-comedogenic and its antimicrobial properties can help with the bacterial component of blemish-prone skin. Its moisture-attracting properties don't add oil — they add water-based hydration.
Does the honey's antibacterial activity survive saponification?
The antimicrobial properties are partially reduced during saponification due to the alkaline pH. However, the humectant, antioxidant, and soothing-feel properties are largely preserved in the finished bar.
Can I use honey soap on my face?
Yes — honey soap is particularly well-suited to facial use. Its gentle, balanced action makes it appropriate for all facial skin types, including sensitive and blemish-prone.
The Bottom Line
Honey in soap isn't a gimmick — it's a millennia-old ingredient with modern scientific validation. Its combination of antimicrobial, humectant, soothing-feel, and antioxidant properties makes it genuinely effective in a well-formulated natural soap bar.
