There is a pattern in how sensitised skin settles, whether the cause was a microneedling session, a chemical peel, a winter of over-exfoliating or a product that simply did not agree with you. The people whose skin settles soonest are rarely the ones who buy the most. They are the ones who stop, strip the routine back to a cleanser and a cream, and let three unglamorous ingredient families do their work.
Panthenol, centella asiatica and the barrier lipids (ceramides, cholesterol, fatty acids) are those families. None of them is new, none of them is exciting on a label, and between them they cover most of what red, tight, reactive skin actually needs. This article explains what each does, what the evidence says, and why they work better with fewer companions.
- Every product is twenty to forty ingredients. A ten-product routine means a few hundred exposures a day on skin that is already reacting, and no way to tell which one is the problem.
- Panthenol (provitamin B5) is a humectant with decades of research behind it; in a moisturizer it helps skin feel hydrated and comfortable.
- Centella asiatica's four triterpenes (madecassoside, asiaticoside, asiatic and madecassic acid) are the "cica" in cica creams, used for a soothing feel; most of the research on them comes from laboratory and small clinical studies.
- Ceramides, cholesterol and fatty acids are what the barrier is made of. Moisturizers for dry and sensitised skin usually combine all three, and laboratory research suggests the combination matters.
Why a simpler routine can be easier on sensitised skin
Start with arithmetic. A typical moisturizer lists twenty to forty ingredients; a serum, fifteen to thirty; a cleanser, twenty or more. A routine of eight to ten products, twice a day, puts a few hundred separate ingredients on your face every day. Our count, not a study, but the logic is hard to argue with: when skin is sensitised, every one of those is a candidate for the sting, and if something flares you cannot tell which.
The second reason is tolerance. Sensitised skin can be more reactive and less tolerant of multiple products, including ingredients that are fine on calm skin and not fine now: fragrance, exfoliating acids, retinoids, vitamin C, alcohol denat. Each extra product is another chance to include one of them. The third reason is friction: more products means more rubbing, more rinsing and more time with wet skin.
So the goal is not "fewer products" as a lifestyle statement. It is fewer products for a few weeks, chosen so that the two you keep are built around ingredients with a real record on sensitised skin. Here are the three families that record belongs to.
Panthenol: the humectant with the longest record
Panthenol is the alcohol form of pantothenic acid, vitamin B5; in the skin it converts to the vitamin, which is why it is called provitamin B5. On the label it reads "panthenol" or "D-panthenol"; the pharmaceutical name is dexpanthenol. Concentrations in cosmetics run from under 1% to about 5%, with 5% at the top of the usual range.
As a humectant it draws and holds water in the outer layer, like glycerin, and it has an unusually long research record. A 2017 review marking seventy years of topical dexpanthenol use, published in the Journal of Dermatological Treatment, summarises the studies on skin hydration and transepidermal water loss; an earlier review in the American Journal of Clinical Dermatology covered the same ground and noted a very low rate of reactions. Those are studies of dexpanthenol preparations, not of any particular cosmetic. In a moisturizer, panthenol's job is the cosmetic one: helping skin feel hydrated, soft and comfortable. That, together with its tolerance record, is why it is such a familiar ingredient in creams for sensitive skin.
Centella asiatica: what the four triterpenes do
Centella asiatica, also called gotu kola or tiger grass, is the plant behind every "cica" product. Its activity comes from four triterpene compounds: asiaticoside, madecassoside, asiatic acid and madecassic acid. On a label they may appear as the extract (Centella asiatica extract or leaf water) or as the named molecules.
Two reviews by Bylka and colleagues, one in Postępy Dermatologii i Alergologii on cosmetology and one in Phytotherapy Research on dermatology, lay out what is known. The reviews describe laboratory research on the triterpenes and a long history of traditional and pharmaceutical use in Europe and Asia; in cosmetics, centella is used for a soothing, comforting feel on skin that looks red or feels reactive. The honest caveat from the same reviews: most of the strongest data is from cell and animal studies and small clinical trials, so centella is best understood as a well-tolerated soother with plausible mechanisms, not a drug. That is still more than most "calming" ingredients can say, and it is why centella sits next to panthenol in almost every post-procedure cream we have looked at.
Ceramides, cholesterol and fatty acids: the 3:1:1 logic
The skin barrier is a wall of flattened cells held in a mortar of lipids, and that mortar has a recipe: roughly half ceramides, a quarter cholesterol, and a smaller share of free fatty acids. When skin feels dry and tight, after a treatment, after over-cleansing, in cold weather, these are the lipids a moisturizer is trying to supplement.
The classic laboratory studies were done by Man, Feingold and Elias in the 1990s. Published in the Journal of Investigative Dermatology, they investigated topical lipid mixtures in relation to the skin barrier and reported that the three lipid classes behaved differently together, in roughly the skin's own proportions (usually summarised as 3:1:1), than one or two of them did alone. That work is why formulators tend to combine them. In cosmetic terms: ceramides, cholesterol and fatty acids are commonly used together in moisturizers for dry and sensitised skin, where they soften the skin and help reduce moisture loss. A 2018 clinical study of a cream built along these lines found a significant increase in skin hydration.
On a label the complete set looks like this: a ceramide (ceramide NP, AP, EOP; "ceramide 3" is ceramide NP), cholesterol, and a fatty acid or its precursor (linoleic acid, phytosphingosine, or a plant oil rich in fatty acids). Squalane and phospholipids are frequent, well-tolerated companions. If you want the longer comparison with humectants, it is in ceramides vs hyaluronic acid: which is better for dry skin?, and the formulator's view of lipid ratios is in biomimetic moisturizers: how to read a label like a formulator.
How the three work together
They are not three versions of the same thing; they are three layers of one job.
Panthenol and glycerin are humectants: they help the outer layer hold water. Centella is there for comfort. The lipids soften the skin and help reduce moisture loss. A cream that has all three covers hydration, comfort and moisture retention; a cream that has one of them plus eight "actives" covers a third of that and adds risk. The rest of the routine's contribution is simply to leave them alone: no exfoliants, no retinoids, no fragrance, no essential oils. If you need the label-reading version of that list, it is in how to read a skincare ingredient list when your skin is sensitised.
A two-product routine built on them
This is a simple routine that may be suitable after a professional procedure, once your provider says gentle skincare can resume, and at any time skin feels sensitised. It is deliberately dull.
- Cleanse, morning and evening: a pH-balanced, fragrance-free foam or cream built on mild surfactants, ideally with panthenol and centella in it so even the wash step is on the right side. Lukewarm water, fingertips, pat dry.
- Moisturize, morning and evening: a cream with panthenol high on the list, a complete lipid set (ceramide, cholesterol, fatty acid or phytosphingosine), humectants, and centella or allantoin. Nothing else.
- Protect, every morning once your provider says to start: a fragrance-free mineral sunscreen.
Then wait. Skin that feels sensitised needs time, not more products, and how long varies from person to person. If it is getting worse rather than better, or not improving after a few weeks, that is a dermatologist's question, not a product question.
The pair we put together for this routine reads exactly like the list above, which is not a coincidence: we chose the products by their ingredient lists, in the way described in microneedling post care: how to choose a cleanser and moisturizer.
Sensitised skin does not need more help. It needs less interference and the three things it is made of.

Panthenol, centella and ceramides FAQ
Is panthenol the same as dexpanthenol?
Yes. Dexpanthenol is the pharmaceutical name for D-panthenol, the active form; "panthenol" on a cosmetic label is the same molecule. It converts to pantothenic acid, vitamin B5, in the skin.
Is centella safe for very sensitive skin?
It is one of the better-tolerated botanicals and is used in post-procedure creams for that reason. Allergy to it is rare but has been reported, as with any plant extract, so patch-test a new centella product on the forearm first if your skin reacts easily.
Do ceramides in a cream actually get into the skin?
In a moisturizer they work where they are applied, in the outermost layer, softening the skin and helping to reduce moisture loss. That is a cosmetic effect and does not depend on deep penetration. What does matter is the company they keep: ceramides with cholesterol and fatty acids, not ceramides alone.
How long until sensitised skin calms down?
It varies from person to person and with the cause, so there is no honest single number. After a procedure, follow your provider's timeline. If things are getting worse, or there is no improvement after a few weeks, see a dermatologist rather than trying another product.
