Understanding Your Skin Type
A question that deserves more than a checkbox
Three online questionnaires, three different answers, and products purchased for three profiles that have nothing to do with each other. What's missing is never information — beauty magazines publish it every month — but a reproducible observation method. Here's one: a timed protocol, a numerical grid, and a table that translates each result into actions. Materials: a gentle cleanser, blotting paper, a mirror, a watch. Cosmetic observation, never medical diagnosis.
What the concept precisely means
The four classic types are based on one observable parameter: the amount of sebum deposited on the surface. Everything else — temporary redness, January tightness, cyclical imperfections, fine lines due to heating — falls under skin condition, which changes in days while the type changes over years.
- Normal skin — stable complexion from morning to evening, no tightness or noticeable shine, discreet pores except on the nose.
- Dry skin — discomfort returns quickly after cleansing, the texture appears fine and matte to the touch.
- Combination skin — forehead, nose, and chin shine during the day while the cheeks remain normal or slightly uncomfortable.
- Oily skin — shine returns everywhere, including the cheeks, with dilated pores on the sides of the nose and recurrent blackheads.
Two qualifiers are added without replacing them: sensitive (reactivity to contact, temperature, certain active ingredients) and mature (signs of aging, including wrinkles). One can have combination and sensitive skin, or dry and mature skin — hence the multi-faceted profile advocated by our brand.
Type, phototype, condition: three different concepts
The most common confusion is between skin type and phototype. The latter describes the reaction to the sun — skin tone, ease of tanning, sun-induced redness — on the Fitzpatrick scale, from I to VI. This has no relation to sebum production: a very fair phototype II can be associated with a marked oily tendency. The division of roles is simple: phototype determines sun strategy, type determines textures, and condition determines what needs adjusting this month.
The blotting paper protocol
Here is the method used to build the Academy's profiles: thirty minutes, repeated identically from one season to another.
| Material | Specification |
|---|---|
| Cleanser | gentle, fragrance-free, pH close to that of the epidermis |
| Blotting paper | 5 mattifying squares of approximately 2 × 2 cm |
| Rinsing water | lukewarm, 20-25 °C, never hot |
| Lighting | natural light, watch and mirror within reach |
Timed procedure
- T = 0. Cleanse face for a maximum of 30 seconds, rinse with lukewarm water, pat dry. Do not apply any skincare product afterward.
- T + 10 min. Note a sensation, from 0 to 3: 0 = no discomfort, 3 = distinct tightness that makes smiling uncomfortable.
- T + 30 min. Press a blotting paper square for 20 seconds on each of the 5 zones: forehead, nose, chin, right cheek, left cheek. Do not rub.
- Count. Place the squares on a white sheet. A square is "marked" when a translucent stain appears against the light.
- T + 120 min (optional). The gap between 30 and 120 minutes differentiates an oily tendency from a normal profile, which is slower to reconstitute its surface film.
NOPAL LIFE Reading Grid
| Squares marked at T+30 | Affected areas | Discomfort at T+10 | Reading |
|---|---|---|---|
| 0 out of 5 | none | 2 to 3 | Dry tendency |
| 0 or 1 out of 5 | nose only | 0 to 1 | Normal profile |
| 2 or 3 out of 5 | forehead, nose, chin — cheeks untouched | 0 to 2 | Combination profile |
| 4 or 5 out of 5 | T-zone and cheeks | 0 to 1 | Oily tendency |
| 2 to 5 out of 5 | variable | 3, with tingling | Restart — see false positives |
Observation benchmark established by the brand, not a standardized instrument: its merit is its consistency, which allows for assessing seasonal evolution. Conditions: in the morning; no exfoliation or mask within 48 hours; same phase of the cycle if comparing two measurements; room at a stable temperature, because 26°C and 17°C do not yield the same blotting paper results.
The six false positives that can skew results
This is the part that questionnaires omit, and it explains most contradictory results. Check that none of these factors were present on the day of the test.
| Situation | Skewed reading | Correction |
|---|---|---|
| Harsh cleanser used for 2 weeks | "dry" — 0 marked square, discomfort 3 | Switch to a gentle formula for 10 days, then retest |
| Hot rinse water | "sensitive" — diffuse redness at T+10 | Rinse with lukewarm water, 20-25°C |
| Hard water, face not properly dried | "dry," with a rough film to the touch | Pat dry thoroughly, or finish with filtered water |
| Heated or air-conditioned air for several days | "dry" when it's dehydration | Add the cheek pinch described below |
| Exfoliation or clay mask the day before | "normal" for an oily profile | Wait 48 hours after any exfoliation or mask |
| Measurement taken in summer, conclusion applied all year | "oily" from January to December | Retest twice a year, in February and July |
The two axes not measured by blotting paper
Dehydration is not dryness
Dry skin lacks oil; dehydrated skin lacks hydration. They feel similar to the touch but are addressed in opposite ways. Oily skin can also be dehydrated, especially in those who frequently use mattifying products. Cheek pinch, 10 seconds: pinch between thumb and index finger and observe against the light. If fine lines appear in the fold and take more than a second to disappear, the hydration axis requires your attention.
| Characteristics | Dry (type) | Dehydrated (condition) |
|---|---|---|
| What's missing | surface lipids | water in the superficial layers |
| Duration | constant, over years | transient, a few days to a few weeks |
| Blotting paper at T+30 | 0 marked square | 0 to 5 — independent |
| Cheek pinch | few lines, fine and matte texture | fine lines that persist for 1 to 2 s |
This point is developed in the next chapter: Skin type vs. skin condition.
Sensitivity and the skin barrier
The skin barrier is the most superficial layer of the epidermis: corneous cells bound by lipids, which limit water loss and filter what enters. If comfortable, it makes treatments well-tolerated; if weakened — by overly strong cleansers, too frequent exfoliation, cold weather, or too many active ingredients — it can make the same routine uncomfortable overnight.
Sensitivity is therefore not a fifth skin type, but a level of reactivity that overlays the others. Signs to look for include: tingling when rinsing, diffuse redness lasting more than 15 minutes, or an unexplained sensation of heat. If these recur with each measurement, note them next to the result: they will influence your choices more than the category itself. Redness that lasts several days, a lesion, or pain are not related to any cosmetic reading — consult a healthcare professional.
Factors that influence the result
| Factor | Observed effect | What to do |
|---|---|---|
| Season | more pronounced lipid deposits in hot and humid weather | a mixed profile in February can appear oily in July: measure twice |
| Age | skin texture changes over decades | many mixed profiles shift to normal then dry; it's the measurement that decides, not age |
| Hormonal cycle | sebum production varies from week to week, cyclic imperfections | always compare at the same phase |
| Cleanser | too harsh, it creates tightness compensated by rich creams, which weigh down the skin | the cycle is broken by changing cleansers, not creams |
| Environment | rinsing, water hardness, heating, air conditioning, wind, sun | affects the condition in a few days, never the type |
Translating your profile into actions
A result that makes no difference in the bathroom is useless. The frequencies below are starting points.
| Profile | Morning cleansing | Moisturising texture | Exfoliation or mask | Prickly pear seed oil | Sign to watch for |
|---|---|---|---|---|---|
| Normal | lukewarm rinse only | light emulsion | 1 × / week | 2 drops in the evening, 2 to 3 evenings / week | shine appearing in the T-zone |
| Dry | milk or balm, no harsh rinsing | rich cream, on still damp face | 1 × / 10 days maximum | 3 to 4 drops in the evening, every evening | tightness still present at T+10 |
| Combination | gentle gel in the T-zone, lukewarm rinse on the cheeks | fluid in the T-zone, cream on the cheeks | 1 × / week, T-zone | 2 drops in the evening, cheeks only | uncomfortable cheeks |
| Oily | gentle non-stripping gel, 30s maximum | gel-cream or fluid — never "nothing" | 1 to 2 × / week | 1 drop, 1 to 2 evenings / week, localised test | more blackheads after a change |
| Sensitive (all types) | fragrance-free, no scalding rinse | short formula, no strong active ingredients | suspended as long as discomfort returns | test in the crook of the elbow 48 h before | redness beyond 15 min |
| Mature (all types) | gentle, never foaming twice a day | nourishing cream + antioxidant serum | 1 × / week, enhanced sun protection | 3 drops in the evening, as a finishing touch | morning comfort, more reliable than evening appearance |
One constant runs through all lines: daily sun protection, as soon as your routines touch on radiance, spots or wrinkles. In the evening, the order remains the same for everyone: makeup removal if necessary, a single targeted active ingredient, comfort cream, vegetable oil as a finishing touch.
Where to place prickly pear seed oil
It's the brand's signature active ingredient, and that's precisely why we refuse to make it a universal answer. Its role is precise, as a finishing touch in the evening: nourishment, suppleness and visible radiance where they are lacking. It replaces neither a moisturiser nor sun protection. It makes perfect sense for dry, mature or tired skin types, and for combination skin applied to the cheeks only. For oily skin, it should be evaluated: one drop, two evenings a week, observing imperfections for two weeks before extending use. The application method matters as much as the dose – warm the drops between your palms and press rather than spread. Detailed composition in the Reference Guide: Prickly pear fact sheet.
Case study: the mistake of four new products
Salima is looking for radiance, a more even skin texture, and comfort. In three weeks, she introduces four products: exfoliating serum, vitamin C, vegetable oil, and a cream rich in active ingredients. Five days later, her skin feels tight in the morning and red when rinsing; she concludes "I'm sensitive" and stops everything. None of these products are bad: what's missing is the method. With four variables introduced together, it's impossible to know which one is causing the problem – and the conclusion is probably wrong, the barrier simply being weakened by the accumulation.
- Days 1 to 14. Minimal foundation: gentle cleanser, hydration, cream, sun protection. No active ingredients.
- Day 15. Blotting paper protocol: the reading is most reliable, as no active ingredients interfere with it.
- Days 15 to 28. Only one active ingredient reintroduced – the one that addresses her priority concern.
- Day 28. Evaluate comfort, radiance, and reactivity. If all is well, prickly pear oil is introduced as a finishing touch in the evening.
- Days 29 to 42. Second active ingredient – or status quo, a perfectly valid decision.
Six weeks seems long compared to promises of results in seven days. However, it is the only rhythm that isolates variables one by one, and therefore the only one that produces actionable information.
Common mistakes
| Mistake | Instead, do this |
|---|---|
| Buying because an active ingredient is trending | check which skin profiles it targets |
| Depriving oily skin of hydration | a light gel-cream: shine and hydration needs are distinct |
| Confusing hydration and nourishment | hydration in the morning, fatty substances in the evening |
| Using oil as sun protection | a dedicated SPF, oil as an evening finish |
| Following generic advice | compare it with your own measured characteristics |
| Prioritising theory over tolerance | when the two contradict, your face is right |

Frequently Asked Questions
How long does the blotting paper test take?
30 minutes after a gentle cleanse, without applying any skincare in between. You press 5 2x2 cm squares for 20 seconds on your forehead, nose, chin and both cheeks.
How to distinguish a combination profile from an oily profile?
By zones, not by intensity. For combination skin, 2 to 3 out of 5 squares are marked and correspond to the forehead, nose and chin. For oily skin, 4 to 5 are marked, including the cheeks: if your cheeks mark the blotting paper, the reading shifts.
Are skin type and phototype the same thing?
No. Phototype describes the skin's reaction to the sun on the Fitzpatrick scale, from I to VI, and guides the sun protection strategy. Skin type describes sebum deposition and guides texture choice. The two are independent.
Can skin be oily and dehydrated at the same time?
Yes, and it's common. The lipid deposit on the surface and the water content of the superficial layers are two independent parameters. Pinching the cheek for 10 seconds can verify this.
How often should the measurement be repeated?
Twice a year, in February and July, to capture seasonal variation. Also after any lasting change in cleanser or climate — but never within 10 days.
Is sensitivity a separate skin type?
No: it's a level of reactivity that overlays the four types. One can be oily and sensitive, or normal and sensitive.
Should the test be redone after changing cleanser?
Yes, but not immediately: allow 10 days of regular use before re-measuring. This is the time after which the blotting paper no longer reflects the old formula rather than the new one.
Key Takeaways
Identifying your skin's tendency requires neither equipment nor budget: five squares of blotting paper, thirty minutes, and a little rigor. What the protocol provides is not a label, but a basis for comparison — one that will tell you, in six months, if something has truly changed or if it's simply winter.

The protocol in brief
Gentle cleansing, 30 minutes wait without skincare, 5 blotting paper squares on key areas, then a grid that translates the count into four profiles — normal, dry, combination, oily — or a resume instruction. Two complementary axes — dehydration and sensitivity — clarify what the measurement doesn't say.
Quick glossary
| Skin Type | Underlying tendency, stable over years, characterized by the amount of sebum deposited on the surface. |
| Phototype | Reaction to the sun, from I to VI on the Fitzpatrick scale; guides sun protection, not textures. |
| Sebum | Naturally produced lipid substance; its production varies from season to season. |
| Blotting paper | Mattifying sheet that reveals by transparency the lipid deposit of a facial area. |
| Skin barrier | The outermost layer of the epidermis; its comfort determines tolerance to skincare products. |
| Dehydration | Transient lack of water, independent of type; checked by pinching. |
| Hydration | Hydrating agents that attract moisture, fatty substances that retain it. |
To remember
- Two figures are enough: the marked squares out of 5 at 30 minutes, and the discomfort from 0 to 3 noted at 10 minutes.
- It's the zones that differentiate combination and oily: if the cheeks mark the blotting paper, the reading shifts.
- Six false positives are enough to reverse a result: check them before concluding.
