Most skincare advice tells you what products to buy. It rarely tells you how to figure out what your skin actually needs before you buy anything. The result: bathroom shelves full of half-used moisturisers that were either too heavy, too light, or just not right — because they were chosen based on a general category (“dry skin”) rather than on what’s actually happening to a specific person’s skin in a specific climate at a specific time of year. This guide changes that.
Why Skin Type Is Not a Fixed Category
The dermatological concept of skin types — dry, oily, combination, sensitive, normal — is a useful starting framework, but it’s a simplification. Your skin’s actual behaviour is determined by a combination of your genetics (your baseline sebum production and skin barrier genetics), your environment (humidity, wind, temperature, UV exposure), your current health and hormonal state, the products you’re currently using, and what you ate, drank, and how you slept this week. This is why the same person can have oily skin in July and dry, flaky skin in January without anything fundamentally changing about their skin.
The American Academy of Dermatology describes the Baumann Skin Type classification system — a more nuanced 16-category system that accounts for the four dimensions of dryness/oiliness, sensitivity/resistance, pigmentation, and wrinkling — as a more clinically accurate way to categorise skin than the traditional five-type model. For practical purposes, understanding that your skin type is dynamic rather than fixed is the most useful thing you can take from this.
The Bare-Face Test: Starting From Your Actual Skin
The most reliable way to understand what your skin needs right now is to observe it without any products for 30 minutes after cleansing. Wash your face with a gentle, non-stripping cleanser (or just warm water). Pat dry. Wait 30 minutes without applying anything. Then observe:
- Tight, rough, or pulling sensation — your skin is dry and your barrier needs lipid replenishment. Look for a richer cream with ceramides, fatty acids, and occlusive plant butters. If it feels tight even after applying moisturiser, you may need an oil layer underneath.
- Shiny all over, particularly forehead, nose, and cheeks — your skin is producing more sebum than it needs. Look for a gel or lightweight lotion with good humectants (hyaluronic acid, glycerin) and consider whether your cleanser might be over-stripping, which triggers compensatory oil production.
- Shiny across forehead and nose but tight or comfortable on cheeks — combination skin. A medium-weight lotion applied more generously to the cheeks and lightly to the T-zone usually works better than separate products for each zone.
- Flushed, reactive, or itchy after cleansing — sensitivity is present. This is a separate dimension from dry/oily and needs to be factored in alongside texture. Look for a fragrance-free, short-INCI-list formula regardless of the texture you need.
- Comfortable and balanced — your skin is broadly in equilibrium. A medium-weight moisturiser with balanced actives is probably your best match; this is the skin type most marketed to but most underserved by heavy creams and aggressive serums.
Understanding What’s Actually Happening vs. What You Perceive
There’s an important distinction between skin that is genuinely dry (lacking in lipids, with a compromised barrier and elevated TEWL) and skin that is dehydrated (lacking water content but with a potentially intact oil layer). These feel similar but have different causes and different solutions.
Genuinely dry skin has insufficient sebum and lipid content. The skin looks dull, feels rough, and may have visible flaking. It needs emollient and occlusive ingredients — plant oils, fatty acids, ceramides, plant butters. A water-heavy lotion with primarily humectant ingredients will not solve it.
Dehydrated skin is a temporary state even oily skin can experience. It feels tight and looks dull, but may also produce shine (because the sebaceous glands are working normally). It responds well to humectants like hyaluronic acid, glycerin, and panthenol without the need for heavy occlusion.
Many people with oily skin think they can’t use a moisturiser. Research in the Journal of Cosmetic Dermatology confirms that even seborrhoeic (oily) skin benefits from hydration — particularly in the form of lightweight humectant serums — and that properly hydrated oily skin often produces less sebum over time, not more.
Matching Texture to the Irish Climate and Your Season
For Irish skin, the time of year is almost as important as skin type when choosing a moisturiser texture. The principles:
- Autumn/Winter (September–February): Go richer. Atlantic wind and indoor heating both increase TEWL. Even combination skin may benefit from a cream in these months. Dry skin almost certainly needs either a rich cream or a lighter cream plus a face oil.
- Spring/Summer (March–August): Go lighter. If your skin is combination or normal, a lotion or gel-cream may be more comfortable and sit better under SPF. Dry skin can usually step down from its richest winter formula to a medium-weight cream.
The Nordic skincare principle of “adapt to your climate” — built into the brand philosophy of Nordic skincare houses because Finnish and Scandinavian winters make it non-negotiable — is exactly the right mental model for Irish skincare. See Why Nordic Skincare Suits Irish Skin for a detailed exploration of this principle.
Reading the Ingredient List for Your Skin Type
Once you know what your skin needs, you can match an ingredient list to it. The first five to seven ingredients in any cosmetic formula make up the majority of the formula by weight. For a moisturiser, these should contain the active humectants, emollients, and occlusives relevant to your skin type:
- Dry skin: look for plant oils (sea buckthorn, rosehip, cloudberry seed), plant butters (shea, kokum), ceramides, glycerin high in the list.
- Dehydrated/oily skin: look for glycerin, hyaluronic acid (sodium hyaluronate), aloe vera, niacinamide. Avoid mineral oil and heavy silicones.
- Sensitive skin: look for allantoin, bisabolol, centella asiatica extract, oat extract. Avoid fragrance (parfum), alcohol denat, essential oils high on the list.
- Mature skin: look for peptides (palmitoyl tripeptide-1, palmitoyl tetrapeptide-7), bakuchiol, vitamin C derivatives, antioxidant-rich plant oils. See our guide to the Best Anti-Ageing Serums for the complementary serum step.

Frequently Asked Questions
How do I know what skin type I am?
The bare-face test is the most reliable starting point: cleanse your face, wait 30 minutes without applying anything, then observe how your skin looks and feels. Tight or rough — dry. Shiny all over — oily. Shiny T-zone with comfortable cheeks — combination. Reactive or flushed — sensitive. Comfortable — normal or balanced. Remember that this can change with the season.
Can your skin type change over time?
Yes. Hormonal changes (puberty, pregnancy, menopause), ageing, medication, diet, climate, and changes in your skincare routine all influence how your skin behaves. Many people find their skin becomes drier and more sensitive in their 40s as sebum production naturally slows. Reassessing your skin type annually and adjusting your routine accordingly is good skincare practice.
Is combination skin a real skin type?
Yes. Combination skin reflects the fact that sebaceous gland density is not uniform across the face — it is higher in the T-zone (forehead, nose, chin) and lower on the cheeks and jaw. This means different areas of the face produce different amounts of oil, which is a normal anatomical variation, not a malfunction.
Should I use different products for different areas of my face?
You can, but it’s rarely necessary. Most people with combination skin find that a single balanced moisturiser applied more generously on drier areas and more lightly on oilier areas gives good results. A targeted serum (like a niacinamide serum on the T-zone) can address local concerns without requiring entirely separate moisturisers.
My skin feels fine but looks dull — what does my skin need?
Dullness without tightness or oiliness is typically a sign of dehydration (lack of water in the skin) or a buildup of dead skin cells on the surface. A hyaluronic acid serum plus a light exfoliating treatment once or twice a week (a low-concentration AHA or a gentle enzyme exfoliant) usually improves radiance significantly within a few weeks.
