Have you ever purchased a highly-recommended skincare product only to find it made your skin worse? The culprit isn’t necessarily the product itself—it’s likely a mismatch with your unique skin profile. The first step of the CLEAR Skin Framework, “Characterise Your Skin,” establishes the foundation for all your skincare decisions.
Why “characterise Your skin” Matters
Skincare isn’t one-size-fits-all. Research published in the International Journal of Cosmetic Science reveals that up to 72% of skincare disappointments stem from product-skin type mismatches. Your skin has unique characteristics shaped by genetics, environment, hormones, and lifestyle—understanding these factors is crucial before selecting any products.
Think of skin characterisation as creating a personalised map. Without it, you’re navigating blindfolded, wasting time and money while potentially causing harm.
Understanding Skin Types
Skin types are determined by how much oil (sebum) your skin naturally produces. While simplified into five main categories, remember that skin exists on a spectrum and can change over time.
Oily Skin
Characteristics: Excess sebum production, visible shine within hours of cleansing, enlarged pores, tendency toward acne and blackheads
Scientific indicators: Higher sebum measurements (>1.5μg/cm²), faster sebum replacement rate
Needs: Oil control, non-comedogenic formulations, gentle exfoliation
Dry Skin
Characteristics: Tight feeling after cleansing, flakiness, fine lines, potential for irritation
Scientific indicators: Lower sebum measurements (<0.5μg/cm²), higher transepidermal water loss (TEWL)
Needs: Lipid replenishment, humectants, minimal cleansing
Combination Skin
Characteristics: Oiliness in T-zone (forehead, nose, chin), dryness on cheeks and perimeter
Scientific indicators: Variable sebum measurements across facial regions
Needs: Balanced approach, potentially different products for different areas
Normal Skin
Characteristics: Balanced sebum production, minimal pores, smooth texture, no sensitivity
Scientific indicators: Optimal sebum levels (0.5-1.5μg/cm²), intact barrier function
Needs: Maintenance, hydration, broad-spectrum sun protection
Sensitive Skin (also consider as skin concern)
Characteristics: Reactivity to products/environment, redness, stinging sensations
Scientific indicators: Compromised barrier function, higher inflammatory markers
Needs: Barrier repair, minimal ingredients, anti-inflammatory components
How to Identify Your Skin Type at Home
While professional analysis provides the most accurate assessment, these scientific methods can help you determine your skin type at home:
The Bare-Face Method
- Cleanse with a gentle, pH-balanced cleanser
- Wait an hour without applying any products
- Observe your skin:
- Shiny all over = Oily
- Tight, flaky = Dry
- Shiny T-zone, normal/dry elsewhere = Combination
- Redness, discomfort = Potentially sensitive
The Blotting Paper Test
- Gently press blotting papers on different facial areas midday (there are brands offer free Blotting Paper Test, e.g. Kiehl’s; so that you don’t need to buy one)
- Hold papers against light to assess oil absorption:
- Heavy oil on all papers = Oily
- Minimal oil = Dry
- Oil from T-zone only = Combination
The Sensitivity Assessment
- Apply a small amount of new product behind your ear (the skin here is very similar to the face)
- Monitor for 24 hours for reactions
- If reaction occurs, note which ingredients were present
Recognising When Skin Type Changes
Your skin type isn’t static—it evolves with age, seasons, hormonal fluctuations, and lifestyle changes. Research shows that 82% of people experience skin type shifts throughout their lives.
Common Triggers for Skin Type Changes:
- Seasonal shifts: Humidity and temperature fluctuations
- Hormonal changes: Menstrual cycle, pregnancy, menopause
- Age progression: Sebum production typically decreases with age
- Medication effects: Particularly hormonal treatments and retinoids
- Geographical relocation: Different climate and pollution levels
- Stress levels: Cortisol can increase sebum production
Signs Your Skin Type Has Changed:
- Products that once worked now cause issues
- New skin concerns emerging
- Different areas becoming problematic
- Changed response to environmental factors
The Skin Quality Assessment Scale: Identifying Your Concerns
Once you’ve identified your skin type, the next step in truly characterising your skin is to assess your specific concerns. This is where the Skin Quality Assessment Scale (SQS) comes in—a practical, science-backed tool that helps you evaluate the key aspects of your skin’s health and appearance.
What Is the Skin Quality Assessment Scale?
The SQS is designed to give you a clear, objective picture of your skin’s current condition. Instead of guessing or relying on vague impressions, the SQS breaks down your skin’s quality into four main domains, each with its own set of concerns. By using a simple 4-point grading system, you can pinpoint which areas need the most attention and track your progress over time.
The Four Domains of Skin Quality
- Texture
This domain looks at the surface of your skin—how smooth or uneven it feels and appears. It includes:- Pores: Are they barely visible, or do they appear enlarged?
- Fine lines and wrinkles: Are there early signs of aging, or deeper creases?
- Scars or roughness: Is the skin surface smooth, or do you notice bumps and irregularities?
- Discolouration
Here, you assess the evenness of your skin tone and the presence of any unwanted colour changes, such as:- Redness: Persistent flushing or visible blood vessels.
- Pigmentation: Dark spots, melasma, or post-inflammatory marks.
- Dullness: Lack of radiance or an overall uneven tone.
- Firmness
This domain measures how taut and resilient your skin feels:- Laxity: Is your skin firm, or do you notice sagging, especially around the jawline or cheeks?
- Volume loss: Are there hollow areas, such as under the eyes or in the cheeks?
- Hydro-Lipid Balance
This assesses your skin’s moisture and oil levels:- Dryness: Does your skin feel tight, flaky, or rough?
- Oiliness: Is there excess shine or a greasy feel, especially in the T-zone?
- Dehydration: Does your skin lack water, feeling papery or looking dull?
How to Use the 4-Point Grading System
For each aspect within the four domains, rate your skin on a scale from 0 to 3:
- 0 (None): No noticeable issue or very mild.
- 1 (Mild): A slight, but noticeable issue.
- 2 (Moderate): A significant, clearly visible issue.
- 3 (Severe): A very noticeable or severe issue that affects your overall skin quality.
Example:
If you have a few fine lines around your eyes but they’re only visible when you smile, you might rate this as a 1 (Mild). If you have persistent redness on your cheeks that’s visible even without makeup, you might rate this as a 2 (Moderate).
Why the SQS Matters
By breaking down your skin’s quality into these specific, measurable categories, you gain a much clearer understanding of your unique skin profile. This approach helps you:
Track Progress: See real, measurable improvements over time, which keeps you motivated and on track.
Prioritise: Focus on the concerns that matter most to you, rather than feeling overwhelmed by everything at once.
Personalise: Choose products and routines that target your specific needs, rather than following generic advice.
Building Your Complete Skin Profile
A comprehensive skin profile considers factors beyond basic type and concerns:
Age Considerations
Skin physiology changes dramatically throughout life:
- Teens/20s: Often oilier, focus on prevention and acne management
- 30s: Early signs of aging, decreased cell turnover
- 40s+: Significant collagen decline, hormonal shifts affecting hydration
Environmental Factors
- Climate impact: Humidity levels affect hydration needs
- Pollution exposure: Increases free radical damage and barrier stress
- UV index: Determines sun protection requirements
- Indoor environments: Heating/cooling systems affect skin hydration
Lifestyle Influences
- Sleep patterns: Poor sleep increases cortisol, affecting barrier function
- Stress levels: Triggers inflammatory responses and disrupts barrier
- Diet quality: Nutritional deficiencies manifest in skin health
- Exercise habits: Affects circulation and detoxification
- Skincare history: Previous treatments may have long-term effects
Putting It All Together
Characterising your skin isn’t a one-time assessment but an ongoing process of observation and adaptation. Document your findings in a skin journal, noting:
- Your primary skin type
- Top 1-2 skin concerns ranked by priority
- Environmental and lifestyle factors that affect your skin
- Seasonal patterns you’ve observed
- Products/ingredients that have caused reactions
This comprehensive profile becomes your skincare compass, guiding all future decisions in the CLEAR Skin Framework. Rather than following trends or generic advice, you’ll make informed choices based on your skin’s unique needs.

FAQs about characterise your skin
Can I have more than one skin type?
Yes. Many people have combination skin with different characteristics in different facial areas. Additionally, your skin type can fluctuate seasonally or with hormonal changes.
How often should I reassess my skin type ?
Perform a full reassessment seasonally (every 3-4 months) and after any significant lifestyle changes, medication adjustments, or geographical moves.
Can skincare products change my skin type?
Products cannot change your genetically-determined skin type, but they can temporarily alter your skin’s behaviour and appearance. Consistent use of appropriate products can help manage your skin type’s challenges.
What if my skin doesn’t clearly fit into any type?
This is common! Skin exists on a spectrum. Focus on identifying your primary characteristics and concerns rather than forcing yourself into a category.
Should I see a professional for skin typing?
While home assessment is valuable, dermatologists and aestheticians can provide more precise analysis using tools like sebum measurements and moisture analysers. Consider professional assessment if you’re struggling with persistent issues.
