Skin type is not a fixed characteristic; it fluctuates with age, season, hormonal phases, climate and changes in routine. A single label such as oily or dry therefore often tells only part of the story. Klaris's four-axis approach was designed to reflect this complexity.
Three Main Axes: Oil, Hydration and Sensitivity
When assessing your skin profile, it helps to observe three independent axes:
- Oil production (sebum): How many hours after washing does your T-zone begin to look shiny?
- Hydration balance: Does your skin feel tight after washing?
- Reactivity (sensitivity): Do you notice redness after trying new products or a change in your surroundings?
The combination of these three axes describes far more profiles than the traditional oily, dry or combination categories.
The Traditional 4 + 1 Profiles
- Oily skin: Shine in the T-zone and often the cheeks, noticeable pores and a quick return of shine after washing.
- Dry skin: Tightness soon after washing, more noticeable flaking during seasonal changes and little shine.
- Combination skin: An oily T-zone with normal or dry cheeks; more visible pores in the central area.
- Normal skin: No marked shine or tightness, and minimal reactivity; a purely normal profile is rarely experienced.
- Sensitive skin: Can occur alongside any of the three types above; reactivity is an additional characteristic rather than one of those types.
Dehydrated Does Not Mean Dry
A common source of confusion is that dehydrated skin is not the same as dry skin. Dry skin describes limited oil production, whereas dehydrated skin describes a lack of moisture (water). Oily skin can also be dehydrated, with oiliness and water shortage occurring together.
Profiles Fluctuate: Seasons and Life Stages
Your skin may feel drier in winter and oilier in summer. Hormonal phases (pregnancy, menopause or oral contraceptive use) can change reactivity and sebum levels. Stress, sleep patterns and diet also affect the signs of a profile.
Rather than saying you have determined your skin type once and for all, asking what your skin's current context is may be a more accurate approach.
Three Practical Observations
- Keep daily notes for a week. Tightness after washing, midday shine and evening reactivity observations can form a simple table.
- Review during seasonal changes. Your profile may have changed, and your routine can adapt with it.
- Distinguish clinical conditions. Medical diagnoses such as acne, eczema, rosacea and atopic dermatitis require assessment by a clinician; a label-reading guide does not replace that.
