Sensitive or reactive skin: Few products, no fragrance, and patience

What it is

Sensitive skin reacts with itching, stinging or redness to products or conditions other skins tolerate: cosmetics, cold, heat, wind. Often it is not skin that was "born" sensitive but skin whose barrier has been damaged by too many products, over-exfoliation or actives that add up.

That is why the first step is almost always to take away, not add: cut the routine to the minimum, with no fragrance or alcohol, and let the barrier recover before introducing anything new.

What it needs

Three things:

Fewer products: the fewer ingredients, the fewer chances to react
Fragrance-free and alcohol-free formulas with soothing, repairing ingredients (ceramides, glycerin, panthenol, colloidal oatmeal, centella)
Well-tolerated sun protection: on very reactive skin, mineral filters tend to irritate less

At the counter

When to recommend it

Itching, stinging or tightness with many cosmetics
Passing redness with cold, heat or after applying a product
After irritation from actives (retinol, acids)
As a recovery routine before reintroducing actives

When not to

Persistent redness with bumps on the cheeks and nose: may be rosacea, refer
A reaction with significant swelling, blisters or one that spreads: refer
Trying several new products at once
Exfoliants and retinol while the skin stings

What to say at the counter. Let us give your skin less work: a gentle cleanser, a fragrance-free soothing cream and sunscreen. Nothing else for a few weeks. Once the stinging stops, we try whatever is needed, one at a time.

Warnings

Important Significant swelling, blisters or a spreading reaction after a product: stop it and refer.
Important Persistent redness with bumps on the central face may be rosacea: it needs a medical diagnosis.
Caution Fragrance is one of the most common causes of contact dermatitis from cosmetics.
Caution Before using a new product on the whole face, try it for a few days on a small area.
Worth knowing "Hypoallergenic" does not guarantee no reaction. In pregnancy this routine, without actives, can be kept up.

The routine, step by step

Morning

Cleanse. Lukewarm water or a very gentle fragrance-free cleanserThe less the skin is handled in the morning, the better.
Moisturise. Fragrance-free soothing cream with ceramides or panthenolRepairs the barrier, which is what reduces reactivity.
Sunscreen. SPF 30 or higher, fragrance-free; mineral if chemical filters stingProtect without adding irritation.

Evening

Cleanse. Fragrance-free milk or micellar cleanser, rinsed off with waterRemoves sunscreen without rubbing.
Moisturise. The same soothing creamConsistency: the barrier recovers over weeks.
Actives. None at first; later, one at a time and patch-tested on a small areaThat way you know what it tolerates and what it does not.

Mineral vs chemical filter on sensitive skin

Aspect	Mineral	Chemical (organic)
How it protects	Reflects and absorbs with zinc oxide or titanium dioxide	Absorbs radiation
Tolerability on reactive skin	Usually better	Some filters can sting
Texture	May leave a white cast	Lighter and clearer
Protection	Good if the SPF is adequate	Good if the SPF is adequate
When to choose it	If chemical filters sting	If well tolerated

Neither is always better: the one the skin tolerates and that gets used every day is the right one.

Self-assessment

Three questions. When you check your answers you will see the explanation for each one.

What is the first step with skin that has become reactive? Exfoliate to renew it Cut the routine to the minimum, fragrance-free Add a new soothing serum every week
Which ingredient is a common cause of reactions to cosmetics? Water Fragrance Glycerin
What should be done with a new product on sensitive skin? Apply it to the whole face from day one Try it for a few days on a small area first Mix it with another to dilute it
