Is an unscented facial serum for right for your sensitive skin?

By Dr. Natacha Bonjout, Pharm.D. in Physiology of Skin Complexion, trained at the Chanel research labs in Paris.

Fragrance makes a serum smell lovely. It does nothing to make it work.

It is also one of the most common causes of allergic reactions to cosmetics. Not everyone needs to avoid it. But if your skin is sensitive or reactive, fragrance is often the first thing worth removing.

The tricky part: "unscented" and "fragrance-free" do not mean the same thing. This fragrance-free skincare guide explains the difference, and the real benefits of fragrance-free skincare.

Why Use Unscented Serums?

Fragrance is a common allergen. It is one of the frequent causes of allergic contact dermatitis, a red, itchy reaction where a product touches the skin.

An allergy can appear later. You can use a fragrance for years before your skin reacts to it. Not everyone becomes allergic, but it happens.

"Fragrance" can hide many ingredients. In the US, a scent made of dozens of components can be listed as one word: "fragrance" or "parfum." That makes it hard to know what you are reacting to.

Natural is not gentler. Essential oils contain allergens too, such as limonene and linalool. Natural describes where an ingredient comes from, not how your skin will react.

A serum stays on your skin. A cleanser rinses off in seconds. A serum, a cream, or a balm stays on for hours. That is why unscented skincare serums matter more than an unscented cleanser.

Skincare for Reactive Skin: Who Benefits Most

• Fragrance-allergic or very reactive skin, especially if you get repeated irritation where you apply your products.

• Eczema- or rosacea-prone skin, which reacts more easily.

• Skin after a procedure, such as a peel or a laser treatment. Follow your practitioner's aftercare, and keep products gentle and fragrance-free.

• Acne-prone skin. Fragrance does not cause acne, but it can irritate skin that is already inflamed.

  Unscented vs. Fragrance-Free Skincare Differences

  Fragrance-free means no ingredients were added to give the product a scent. In the US, there is no official definition, so it is still worth reading the label.

  Unscented only means the product has little or no smell. It can still contain fragrance ingredients, added to mask the natural smell of the formula.

  That is the whole debate of fragrance-free vs unscented serums. So when choosing serums for sensitive skin, trust the ingredient list, not the front of the box.

  What to Check on the Label

  • "Fragrance" or "parfum."

  • Essential oils, such as lavender, rose, citrus, tea tree, or peppermint.

  • Fragrance allergens listed by name: limonene, linalool, geraniol, citronellol, eugenol, or coumarin.

  If you have a known fragrance allergy, a dermatologist can run a patch test to tell you exactly which ingredients to avoid.

  Why We Made Le Balm Unscented

  Le Balm Unscented is the same 68-active, waterless solid serum as Le Balm, without the fragrance. And despite its name, it is fully fragrance-free: none of the fragrance allergens above appear in its ingredient list.

  It is dermatologist tested, hypoallergenic, and non-comedogenic, and was designed for sensitive, reactive, redness-prone, and allergen-prone skin. It helps repair a damaged skin barrier, including after a laser treatment or retinol. That makes it one of the best serums for sensitive skin in our range, because there is nothing in it your skin does not need.

  The Bonjout Take

  Fragrance is a pleasure, not a performance ingredient. For sensitive skin, removing it is one of the simplest ways of reducing skin irritation with fragrance-free products.

  Luxury does not need a scent. It is in how carefully a formula is built, and in every ingredient earning its place.
