"Fragrance-free" tells you what's been left out. It says nothing about what's been put in. A good fragrance-free moisturiser needs humectants to draw in water, emollients to soften the skin surface, and barrier-supporting ingredients to hold everything together — here's how to read a label and know what you're actually getting.
Fragrance-Free vs Unscented: Why the Difference Matters
These two terms are frequently used interchangeably on packaging, but they mean different things. Fragrance-free means no fragrance compounds have been added — no parfum, no synthetic perfume, no essential oils used for scent. Unscented, by contrast, often means masking fragrances have been added to neutralise the natural smell of other ingredients. An unscented product can still cause fragrance reactions.
For anyone with rosacea, eczema, contact dermatitis, or Multiple Chemical Sensitivity (MCS), this distinction is significant. Fragrance is the leading cause of allergic contact dermatitis in cosmetics — identified as a problem ingredient in the EU's Cosmetics Regulation and listed as one of the 26 mandatory allergen disclosures. An unscented product that uses masking fragrance provides no meaningful protection.
Label check
Fragrance can hide in ingredient lists under several names: parfum, fragrance, essential oil names (lavender oil, rose flower oil, citrus extract), and compounds like linalool, limonene, or geraniol — all of which are naturally occurring fragrance chemicals that must be declared separately in the EU when above threshold concentrations. If any of these appear in a product marketed as "unscented", it still contains fragrance.
The Three Categories of Moisturising Ingredients
A moisturiser does not work through a single mechanism — it works through three complementary ones. Understanding these categories makes it far easier to evaluate whether a product will actually perform for your skin type.
| Ingredient | Type | What it does |
|---|---|---|
| GlycerinGlycerin (from non-GMO Soy Oil in Boë products) | Humectant | Naturally present in healthy skin as part of the NMF (Natural Moisturising Factor). A hygroscopic ingredient — it attracts moisture from the surrounding air and retains it in the outer skin layers. Strengthens the skin barrier, improves penetration of other actives, and helps maintain the moisture balance that keeps skin soft and elastic. |
| Shea ButterButyrospermum Parkii Butter | Emollient | Rich in stearic and linoleic fatty acids, plus antioxidants including quercetin. Its fatty acid composition closely resembles the skin's own lipid makeup, allowing it to integrate with the barrier rather than simply coat it. Mild anti-inflammatory properties make it well-suited for dry or eczema-prone skin. Boë sources refined shea butter directly from Burkina Faso, West Africa. |
| Sweet Almond OilPrunus Armeniaca Kernel Oil | Emollient | A lightweight, fast-absorbing oil rich in oleic acid and omega-6 and omega-9 fatty acids, plus vitamin E. Soothes and softens without occlusive heaviness or greasy residue. Leaves a velvety finish and is well tolerated by most sensitive skin types (note: patch test advised for those with nut allergies). |
| Sodium PCASodium PCA (from L-Glutamic acid) | Humectant | A salt of pyrrolidone carboxylic acid, naturally abundant in skin as part of the NMF. Highly effective at drawing and binding water to the skin — more so than glycerin alone. For rosacea and eczema skin, it helps maintain hydration without any occlusive weight, reducing the barrier disruption that triggers flares. |
| Hydrogenated Ethylhexyl OlivateOlive oil-derived ester | Emollient Barrier | A biocompatible emollient derived from olive oil. Unlike many plant oils, it integrates with the skin's own lipid structure, filling the intercellular gaps rather than sitting on top. Reduces transepidermal water loss without clogging pores — a key property for eczema and acne-prone skin. |
| Glyceryl GlucosidePlant-derived aquaporin activator | Humectant Barrier | Activates aquaporins — the skin's own water-transport channels — promoting deep hydration at a cellular level rather than just on the surface. This mechanism is particularly valuable for chronically dehydrated skin, including rosacea and mature skin where aquaporin expression is reduced. |
| Stearic AcidFatty acid | Occlusive Barrier | A saturated fatty acid that forms part of the skin's natural lipid matrix. In a moisturiser, it acts as an emulsifier and mild occlusive, helping to seal in the humectants and emollients applied with it. Non-irritating and well tolerated by all skin types including sensitised skin. |
| UreaCarbamide | Humectant | Naturally present in the skin's NMF. At low concentrations (2–5%), urea is a powerful humectant and mild keratolytic — it softens the outermost skin layer, improving water retention and the absorption of other actives. At higher concentrations it becomes an exfoliant, but in standard moisturisers it functions purely as a hydration ingredient. |
Ingredients to Avoid in a Moisturiser for Sensitive Skin
Knowing what a good fragrance-free moisturiser contains is only half the picture. Equally important — especially for rosacea, eczema, or reactive skin — is knowing what to avoid:
| Ingredient | Why to avoid it | Risk level |
|---|---|---|
| Fragrance / Parfum | Leading cause of contact dermatitis. Triggers flushing and vascular reactivity in rosacea. Declared allergen under EU Cosmetics Regulation. | High |
| Essential oils (lavender, rose, citrus) | Natural does not mean hypoallergenic. Essential oils contain linalool, limonene, and geraniol — all EU-declared fragrance allergens. A common source of reactions in "natural" skincare. | High |
| Denatured alcohol (SD Alcohol) | Rapidly strips the skin's lipid barrier, accelerating transepidermal water loss. Worsens both eczema dryness and rosacea flushing. | High |
| Parabens | Potential sensitisers over long-term use. May disrupt the skin's microbiome and increase reactivity. Absent from all Boë products. | Medium |
| Methylisothiazolinone (MIT) | A preservative classified as a top contact allergen by dermatologists. Banned in leave-on cosmetics in the EU since 2016. Still appears in some products sold outside the EU. | High |
| Endocrine disruptors | Certain synthetic ingredients (e.g. some UV filters, preservatives) interfere with hormonal signalling. May worsen hormonally-triggered rosacea subtypes and are generally avoided in clean formulations. | Medium |
| Witch hazel (high alcohol forms) | Often marketed as a soothing botanical, but many witch hazel extracts are formulated with alcohol and tannins that are drying and irritating for rosacea skin. | Medium |

Frequently Asked Questions
What does fragrance-free actually mean on a moisturiser label?
Fragrance-free means no fragrance compounds have been added — no parfum, no synthetic perfume, and no essential oils used for scent. It differs from "unscented", which can still contain masking fragrances to neutralise the smell of other ingredients. A truly fragrance-free product should contain no entry for "parfum", "fragrance", or named essential oils like lavender oil or rose oil in its ingredient list.
What is the difference between a humectant, an emollient and an occlusive?
Humectants (glycerin, hyaluronic acid, sodium PCA) draw water into the skin and retain it. Emollients (shea butter, plant oils, squalane) fill gaps between skin cells and smooth the surface. Occlusives (plant waxes, stearic acid, beeswax) form a seal on the skin surface to prevent water evaporation. A well-formulated moisturiser includes all three — using only one category produces incomplete results.
Why is glycerin so important in a fragrance-free moisturiser?
Glycerin is a humectant naturally found in the skin's Natural Moisturising Factor (NMF). It is hygroscopic — attracting water from the air and retaining it in the outer skin layers. It also strengthens the skin barrier and improves the penetration of other actives. Plant-derived glycerin from non-GMO soy oil is 100% natural and vegan.
What makes shea butter good for dry and sensitive skin?
Shea butter (Butyrospermum Parkii Butter) contains stearic and linoleic fatty acids that closely mirror the skin's own lipid composition, allowing it to integrate with and reinforce the skin barrier. Its antioxidant content (including quercetin) gives mild anti-inflammatory protection. It is non-greasy, non-comedogenic at standard use concentrations, and well tolerated by most sensitive skin types.
What should I avoid in a moisturiser if I have rosacea or eczema?
Avoid fragrance (parfum), essential oils (even "natural" ones), denatured alcohol, parabens, methylisothiazolinone (MIT), and endocrine-disrupting ingredients. For rosacea specifically, also avoid menthol and witch hazel — both commonly marketed as soothing but often irritating. The safest moisturisers for reactive skin are those formulated with no fragrance, no alcohol, and no allergens as a baseline standard.
Is sweet almond oil good for sensitive skin?
Sweet almond oil (Prunus Armeniaca Kernel Oil) is a lightweight emollient rich in oleic acid, omega-6 and omega-9 fatty acids, and vitamin E. It absorbs quickly, leaves no greasy residue, and is generally well tolerated by sensitive skin. Those with nut allergies should patch test before use. It is non-comedogenic at concentrations typically found in leave-on moisturisers.
Can I use a fragrance-free moisturiser under self-tanner?
Yes — and for reactive skin, it's recommended. Applying a fragrance-free moisturiser to drier areas before self-tanner smooths the surface so colour develops more evenly. After tanning, daily moisturising with a fragrance-free formula prolongs the result and prevents the dryness that can trigger eczema flares or rosacea irritation. Products like Boë's No.3 Tan Lotion function as both — a moisturiser and a gradual self-tanner in one formula.
