How Do I Know What My Skin Type Is?

If you’ve ever asked yourself, “Which is my skin type?” — you’re not alone.

Understanding your skin type is one of the most important steps in building an effective skincare routine. Using products that don’t match your skin’s biological needs can disrupt your barrier, worsen breakouts, or increase dryness.

Why Skin Type Matters

Your skin type is largely determined by:

Sebum (oil) production
Barrier function
Water retention capacity
Sensitivity level

The outermost layer of your skin — the stratum corneum — plays a key role in regulating hydration and protecting against environmental stressors (Proksch et al., 2008).

When the barrier is balanced, skin looks smooth and resilient. When it’s disrupted, you may notice dryness, oiliness, irritation, or breakouts.

To accurately assess your skin type, go makeup-free and avoid heavy skincare products for a full day so you can observe your skin’s natural behavior.

What Are the Types of Skin?

1. Oily Skin

Oily skin is characterized by overactive sebaceous glands, which produce excess sebum.

Signs of oily skin:

Visible shine (especially in the T-zone)
Enlarged pores
Skin feels greasy to the touch
Shine returns within 30–60 minutes of washing
Frequent blackheads or acne

Excess sebum production is one of the key contributors to acne development (Dreno et al., 2018).

If you have oily skin, lightweight, non-comedogenic formulations are essential.

Recommended Support:
Rejuvaskin Anti-Pollution Cleanser and Mineral Facial Sunscreen help gently cleanse without over-stripping the barrier.

2. Dry Skin

Dry skin produces insufficient sebum and often has a compromised barrier.

Common signs:

Tightness
Flaking
Redness
Burning sensation
Rough texture

Dry skin is associated with increased transepidermal water loss (TEWL), meaning moisture escapes more easily (Proksch et al., 2008).

If you have dry skin, barrier repair and hydration are critical.

Recommended Support:
Rejuvaskin Skin Recovery Cream is designed to support hydration and barrier integrity.

3. Combination Skin

Combination skin includes both oily and dry areas — typically:

Oily T-zone (forehead, nose, chin)
Dry or normal cheeks

This skin type may fluctuate with:

Weather
Hormones
Product use

Targeted skincare — using different products in different areas — often works best.

Recommended Support:
Rejuvaskin Facial Moisturizer provides balanced hydration without excess heaviness.

4. Sensitive Skin

Sensitive skin is defined by heightened reactivity.

Triggers may include:

Retinol
Salicylic acid
Benzoyl peroxide
Fragrance
Sun exposure
Mechanical friction

Symptoms include:

Redness
Itching
Stinging
Burning

Sensitive skin often reflects a compromised barrier (Proksch et al., 2008).

Gentle, fragrance-free, barrier-supportive products are key.

Recommended Support:
Rejuvaskin’s gentle Anti-Pollution Cleanser helps cleanse without irritation.

5. Acne-Prone Skin

Acne-prone skin is not strictly a “skin type,” but rather a condition influenced by:

Excess sebum
Follicular hyperkeratinization
Bacterial imbalance
Inflammation (Dreno et al., 2018)

You may have oily, combination, or even dry skin and still be acne-prone.

Understanding the underlying cause — hormonal, bacterial, or oil-related — helps guide treatment.

Recommended Support:
Rejuvaskin Anti-Pollution Cleanser helps maintain balance without over-stripping.

6. Normal Skin

Normal skin has:

Balanced oil production
Minimal sensitivity
Rare breakouts
Smooth texture

The barrier functions efficiently, and hydration levels are stable.

At-Home Skin Type Test

To determine your skin type:

Wash your face with a gentle cleanser.
Pat dry.
Do not apply any products.
Wait 6–8 hours.
Observe your skin.

Ask Yourself:

1. Is your skin shiny or greasy?
Yes → Oily or combination
No → Normal or dry

2. Is only your T-zone shiny?
Yes → Combination
No → Oily

3. Does your skin feel tight or uncomfortable?
Yes → Dry or combination
No → Oily or normal

4. Do you see flaky or “ashy” patches?
Yes → Dry or combination
No → Oily or normal

5. Do products easily irritate your skin?
Yes → Sensitive
No → Non-sensitive

6. Do you consistently experience breakouts?
Yes → Acne-prone
No → Not acne-prone

Important: Skin Type vs Skin Condition

Your skin type is generally stable over time.
Your skin condition can change.

For example:

Dehydration can affect oily skin
Hormones can temporarily increase oil production
Climate can impact barrier function

Building a routine that supports barrier health helps maintain long-term balance (Proksch et al., 2008).

Knowing your skin type allows you to choose products that support — rather than fight — your skin’s natural biology.

Oily skin requires balance.
Dry skin requires barrier repair.
Combination skin requires targeted care.
Sensitive skin requires gentleness.
Acne-prone skin requires thoughtful management.

Understanding your skin is the foundation of effective skincare.
