Skin Guide
A clinic guide to sensitive skin.
Sensitive skin is one of the most common concerns people bring to the clinic. A large worldwide study found that around 71 per cent of adults have sensitive skin, and around 40 per cent describe it as moderate to severe. If your skin stings, itches, flushes or reacts to almost everything, you are far from alone.
Every skin plan at Plumerian Aesthetics Bentleigh begins with a complimentary thirty-minute consultation with an AHPRA-registered nurse. What follows is educational context, not a personal treatment plan.
Quick answer: Sensitive skin is skin that reacts more easily than average to products, temperature, weather or emotional stress. It affects around 71 per cent of adults. Symptoms include stinging, itching, redness, tightness and flushing. Sensitive skin is manageable with a stripped-back routine focused on barrier repair, gentle cleansing, mineral SPF and avoiding known irritants.
What is sensitive skin?
Sensitive skin (sometimes called reactive skin) is defined as a syndrome where unpleasant sensations (stinging, burning, itch, tingling) show up in response to things that would not affect non-sensitive skin. It can sit alongside acne, rosacea, psoriasis or eczema, or it can appear on its own with skin that looks completely normal or just slightly red.
The most sensitive part of the face is the nasolabial fold (from the nostril to the outer corner of the mouth), then the cheekbones, chin, forehead and upper lip.
What are the symptoms of sensitive skin?
- Itch
- Dryness and flakiness
- Roughness
- Flushing, blushing or redness
Why does sensitive skin happen?
Reduced hydration
Studies show sensitive skin is more dehydrated, has a thinner outer layer, and often has fewer ceramides. The result is more water loss and easier absorption of things that irritate.
Low-grade inflammation
Biopsies of sensitive skin usually show some baseline inflammation. Inflammation causes itch and dryness, and quietly accelerates skin ageing.
An altered skin microbiome
Sensitive skin tends to have less diversity in the community of bacteria and fungi living on it. Like the gut, a less diverse skin microbiome is linked to a less resilient immune response.
Nerve changes
Sensitive skin has higher levels of a chemical called nerve growth factor, which means more sensory nerves in the skin, and often more sensitive nerves. Very sensitive skin has been shown to be twice as common in people with irritable bowel syndrome, and nerve hypersensitivity is thought to be a shared thread.
Stress
Stress ramps up abnormal immune responses in the skin, which fuels inflammation. Sensitive skin often flares in step with life.
Other contributors
- Genetics, especially a family history of eczema
- Being female (sensitive skin is more common in women)
- Smoking
- The nocebo effect (expecting something to sting or itch often makes it happen)
What triggers sensitive skin?
- Chemical: cosmetics (the biggest single trigger), soaps, hair dyes, pollutants
- Environmental: UV, heat, cold, low humidity, wind
- Mechanical: friction, pressure, mask wear
- Hormonal: menstrual cycle, perimenopause and menopause
If you have not identified your triggers, keep a simple diary for two to four weeks. You will start to see the pattern.
What is the best skincare routine for sensitive skin?
Sensitive skin has been under-researched, so guidelines are still evolving. The four principles that consistently show up: cleanse gently, hydrate, strengthen the barrier, and avoid known irritants. Everything below is stocked at Plumerian Aesthetics Bentleigh.
A gentle, low-pH cleanser (twice daily)
Soap and high-pH cleansers strip the barrier and make sensitive skin worse. A creamy, low-pH cleanser lifts oil and grime without leaving skin feeling tight or squeaky.
Niacinamide, for calm and barrier repair
Niacinamide is one of the best-evidenced ingredients for sensitive, inflammation-prone skin. It reduces redness, calms inflammation, strengthens the barrier, and is safe up to 10 per cent in humans without irritation. It is the first serum most sensitive skin should try.
Hyaluronic acid, for hydration without irritation
Hyaluronic acid holds water in the skin without any active ingredients that could sting. The best formulations combine molecular weights above and below 300 kDa, so some sits on the surface as a moisture barrier while the rest gently hydrates deeper down.
Ceramides, for the skin barrier
Ceramides are structural fats that keep the skin barrier intact and hold water in. Adding them back into the routine reduces inflammation and transepidermal water loss over a few weeks.
Daily zinc oxide sunscreen
UV is one of the most common sensitive-skin triggers. Mineral (zinc oxide, titanium dioxide) sunscreens are far better tolerated on sensitive skin than chemical filters. Zinc oxide is also naturally anti-inflammatory.
Yes, you can still do anti-ageing skincare
Sensitive skin does not mean giving up on evidence-based anti-ageing ingredients. It just means choosing the well-tolerated ones and introducing them slowly.
Retinal (the gentle form of vitamin A)
Vitamin A has more evidence than any other cosmeceutical ingredient for smoothing, evening tone and supporting collagen. Retinaldehyde (retinal) is around 20 times stronger than retinol and is extremely well tolerated, even on sensitive skin. Start with a lower strength two or three times a week and build from there.
Peptides, for firmness without irritation
Small proteins that support collagen and skin structure. Palmitoyl tripeptide-1 has been compared to vitamin A minus the irritation. A good option for sensitive skin that cannot tolerate active nights.
4-n-butyl resorcinol (4NB), for pigmentation without redness
The most potent tyrosinase inhibitor available in cosmeceutical skincare and one of the best tolerated. Very well suited to sensitive skin dealing with sun spots or melasma, without the irritation risk of hydroquinone.
An overnight hydrating mask, once or twice a week
Deep barrier support overnight. Reinforces water content and reduces stinginess over a few weeks.
Tread with caution
- Alpha hydroxy acids (AHAs). Chemical exfoliators that are well-known sensitive-skin triggers. Introduce only if your barrier is healthy, and start slowly.
- Vitamin C. Anti-inflammatory in theory, but the acidic form (L-ascorbic acid) can sting sensitive skin. Patch test first.
- Chemical (organic) sunscreens. Higher irritation risk than mineral sunscreens.
Avoid altogether
- Soaps and cleansers with a pH at or above 7
- Fragranced skincare, including essential oils
- Anything you have had a previous reaction to
Top skincare hacks for sensitive skin
- Cleanse with a creamy, low-pH cleanser, not a foaming one
- Pat skin dry after cleansing, do not rub
- Apply moisturisers to damp skin (studies show this reduces itch and improves hydration)
- Use a mineral zinc oxide sunscreen daily
- Retinal is the best-tolerated vitamin A. Start low, go slow
- Patch test new products on the inside of the wrist or behind the ear before using on the face
Perimenopause and menopause make skin more sensitive
Falling oestrogen means less hyaluronic acid, less oil, and a more fragile barrier. A Dutch study found 32 per cent of peri- and postmenopausal women describe their skin as sensitive, often with bumps, dryness, itching and redness. If this is you, our perimenopause guide and menopausal skin guide go deeper on the hormonal side.
What in-clinic treatments help?
Sensitive skin is not a barrier to in-clinic care, but the right treatments matter more than usual. These are options we can talk through at your complimentary thirty-minute consultation with an AHPRA-registered nurse.
Skin hydration therapy
Injectable hyaluronic acid delivered directly into the skin. Reinforces water content and skin quality in a way no topical can match. Well suited to skin that runs dehydrated and reactive.

Rejuran
A polynucleotide skin-healing treatment that supports the skin’s own repair processes. For sensitive skin where the barrier and inflammatory tone need calming, treatments that support skin healing are worth considering.
All of these are conversations for your consultation, not decisions from a website.
Frequently asked questions
What is sensitive skin?
Sensitive skin is a state where the skin barrier is compromised and reacts more easily than average to skincare, weather, hot water, alcohol or stress. Around 71 per cent of adults describe having some degree of sensitive skin, and about 40 per cent describe it as moderate to severe.
What causes sensitive skin?
Common causes include a genetically thinner or compromised skin barrier, over-exfoliation, harsh cleansers, fragrance, alcohol-based products, environmental exposure (sun, wind, cold), certain medical conditions (rosacea, eczema, dermatitis), and hormonal changes such as perimenopause.
What ingredients should sensitive skin avoid?
Avoid or minimise fragrance, essential oils, denatured alcohol, physical scrubs, high-concentration acids (glycolic above 10 per cent), and starting multiple actives at once. Chemical sunscreens can also trigger reactive skin in some people; mineral SPF is generally better tolerated.
What is the best skincare routine for sensitive skin?
Twice-daily gentle pH-balanced cleanser, a barrier-supporting moisturiser with ceramides, niacinamide and cholesterol, and daily mineral SPF. Introduce actives one at a time and slowly. If the barrier is currently damaged, spend two to four weeks on barrier repair before adding anything else.
Is sensitive skin permanent?
Not usually. Most sensitive-skin episodes are caused by a damaged barrier from over-exfoliation or harsh products. With four to eight weeks of gentle barrier-repair care, most people see substantial improvement. Chronic sensitivity from rosacea, eczema or hormonal change may need ongoing management.
Can sensitive skin use retinal or retinoids?
Often yes, but slowly. Start with the lowest strength retinal (0.05 per cent) two nights a week, buffered by moisturiser, and build tolerance over two to three months. If your barrier is currently damaged, repair it first before introducing any retinoid.
What SPF is best for sensitive skin?
Broad-spectrum mineral sunscreens using zinc oxide (and sometimes titanium dioxide) are best tolerated by sensitive skin. They sit on the surface rather than being absorbed, cause less stinging, and are calming rather than inflammatory. Reapply every two to three hours when outdoors.
