Skincare is not a one-size-fits-all process. Understanding your skin type is crucial for developing a skincare routine that is both effective and safe. Each skin type—normal, oily, dry, combination, and sensitive—has unique characteristics and needs. Using products that are not suited for your skin type can disrupt the skin's natural balance, leading to irritation, breakouts, or excessive dryness (Bergfeld, 2021).

One of the most critical and often overlooked factors in skincare is skin pH. The normal pH range of human skin is between 4.5 and 5.5, making it slightly acidic. This acidic environment, known as the acid mantle, plays a vital role in protecting the skin from pathogens, maintaining moisture, and supporting the skin's barrier function (Lambers et al., 2006; Fluhr, Darlenski, & Angelova-Fischer, 2014).

Disruption of this pH balance—often due to the use of alkaline products like soap with high pH or certain aggressive treatments—can lead to increased transepidermal water loss (TEWL), dryness, and susceptibility to bacterial infections and inflammation (Ali, Yosipovitch, & Maibach, 2019; Rippke, Schreiner, & Doering, 2004). Therefore, preserving the skin’s natural pH through appropriate skincare products is essential for all skin types.

For example:

·         Oily skin may benefit from pH-balanced cleansers that control excess oil without stripping the acid mantle (Del Rosso, 2013).

·         Dry skin, which often has a higher pH, requires acidic, hydrating products to help restore the optimal balance (Egawa & Tagami, 2008; Rawlings & Matts, 2020).

·         Sensitive skin may react negatively to pH-disruptive products, increasing the likelihood of irritation (Denda, Hosoi, & Asida, 2017; Kim, Leung, & Boguniewicz, 2022).

Hence, selecting skincare products with a pH close to the natural range (4.5–5.5) is fundamental to maintaining skin health and tailoring routines to individual skin types.

Our skin is a living organ that interacts with the environment and responds to both external and internal stimuli. Skincare routines should aim to support the skin’s barrier function, maintain its pH balance, and promote regeneration (Proksch, Brandner, & Jensen, 2020). For example, applying heavy creams on oily skin may clog pores, while using harsh exfoliants on sensitive skin may cause inflammation (Zlotogorski, 2020). Therefore, knowing your skin type helps you select suitable ingredients and avoid harmful practices.

How to Identify Your Skin Type

Identifying your skin type is the foundation for any effective skincare routine. Here's how to distinguish the different types:

·         Normal skin: Balanced oil and moisture; few imperfections; minimal sensitivity. Appears smooth and radiant with small pores and rarely experiences breakouts or flaking (Draelos, 2018).

·         Oily skin: Excess sebum production; enlarged pores; prone to acne. Tends to look shiny, especially in the T-zone (forehead, nose, chin), and may feel greasy throughout the day (Del Rosso, 2013).

·         Dry skin: Flaky or rough texture; dull complexion; tightness. Often caused by a weakened lipid barrier, leading to increased transepidermal water loss (TEWL) (Rawlings & Matts, 2020).

·         Combination skin: Oily in the T-zone; dry or normal elsewhere. Requires targeted treatment depending on the area (Draelos, 2018).

·         Sensitive skin: Easily irritated; redness and burning sensations; may react to certain ingredients or environmental factors like temperature changes (Kim, Leung, & Boguniewicz, 2022).

A simple way to identify your skin type is the blotting sheet method. After washing your face and waiting a few hours, press a blotting paper on different parts of your face. If it shows oil from the T-zone only, you likely have combination skin; if the whole sheet is oily, your skin is oily; and if it’s mostly dry, you have dry skin (Draelos, 2018).

Skincare Routine for Normal Skin

Normal skin is the most balanced and low-maintenance of all skin types. However, that does not mean it should be neglected. Maintenance is key.

·         Cleanser: Use a gentle, pH-balanced cleanser to remove dirt and oil without stripping natural moisture (Ananthapadmanabhan et al., 2004).

·         Moisturizer: Lightweight, non-comedogenic moisturizers help maintain hydration without greasiness (Loden, 2020).

·         Sunscreen: Daily SPF 30+ sunscreen protects against UV-induced premature aging and hyperpigmentation (Proksch et al., 2020).

·         Tip: Use antioxidants like vitamin C to prevent oxidative stress and maintain a radiant complexion (O'Neill et al., 2021).

Skincare Routine for Oily Skin

Excess oil can clog pores and lead to breakouts, but over-stripping the skin can make oil production worse.

·         Cleanser: Choose foaming or gel cleansers with salicylic acid to gently exfoliate and control sebum (Del Rosso, 2013).

·         Toner: Use an alcohol-free toner with niacinamide or witch hazel to tighten pores and reduce shine (Bergfeld, 2021).

·         Moisturizer: Opt for oil-free or gel-based moisturizers containing hyaluronic acid (Loden, 2020).

·         Sunscreen: Lightweight, matte-finish sunscreens work well to prevent additional greasiness (Proksch et al., 2020).

·         Tip: Clay masks once a week can absorb excess oil and purify pores (Draelos, 2018).

Skincare Routine for Dry Skin

Dry skin is prone to flaking, irritation, and a compromised barrier. The goal is to hydrate and protect.

·         Cleanser: Use creamy, non-foaming cleansers with hydrating ingredients like glycerin or ceramides (Rawlings & Matts, 2020).

·         Moisturizer: Look for thick creams or ointments containing shea butter, ceramides, or squalane (Loden, 2020).

·         Serum: Incorporate hyaluronic acid and panthenol for deep hydration (Kaur, Kapila, & Agrawal, 2021).

·         Sunscreen: Moisturizing SPF formulas prevent further dryness and sun damage (Proksch et al., 2020).

·         Tip: Avoid hot water and alcohol-based products, which strip moisture (Denda et al., 2017).

Skincare Routine for Combination Skin

Combination skin needs tailored care for both oily and dry areas.

·         Cleanser: Use a gentle cleanser that balances oil without over-drying (Draelos, 2018).

·         Moisturizer: Apply a lightweight lotion all over, and add richer cream to drier areas (Loden, 2020).

·         Exfoliant: Use BHA (Beta Hydroxy Acid) in the T-zone and a gentle AHA (Alpha Hydroxy Acid) on drier patches (Del Rosso, 2013).

·         Sunscreen: Choose non-comedogenic, broad-spectrum SPF (Proksch et al., 2020).

·         Tip: Multi-masking (different masks for different areas) can address both oily and dry zones simultaneously (Draelos, 2018).

Skincare Routine for Sensitive Skin

Sensitive skin requires minimal, soothing, and fragrance-free formulations.

·         Cleanser: Choose mild, pH-balanced, non-foaming cleansers with calming agents like allantoin or chamomile (Kim, Leung, & Boguniewicz, 2022).

·         Moisturizer: Use barrier-repair creams with ceramides and niacinamide (Loden, 2020).

·         Serum: Apply calming serums with ingredients like green tea or Centella asiatica (Kim & Kim, 2022).

·         Sunscreen: Physical (mineral) sunscreens with zinc oxide or titanium dioxide are less irritating (Kim, Leung, & Boguniewicz, 2022).

·         Tip: Patch-test new products before full application and avoid known irritants (Draelos, 2018).

Importance of Routine Order

The sequence of product application affects their absorption and efficacy. Follow this order:

1.     Cleanser

2.     Toner (optional)

3.     Serum

4.     Eye cream (optional)

5.     Moisturizer

6.     Sunscreen (AM) or retinoid (PM)

Apply from the thinnest to the thickest consistency to optimize benefits (Draelos, 2018).

  Ingredients to Embrace and Avoid by Skin Type

Skin Type	Embrace	Avoid
Oily	Salicylic acid, niacinamide	Heavy oils
Dry	Ceramides, hyaluronic acid	Alcohol
Sensitive	Allantoin, panthenol	Fragrance, essential oils

Sasonal Adjustments

Skin changes with the weather. In winter, use thicker creams and gentler exfoliants. In summer, switch to lightweight moisturizers and prioritize sun protection (Draelos, 2018).

Common Mistakes to Avoid

·         Over-exfoliating

·         Skipping sunscreen

·         Using too many active ingredients at once

·         Not adjusting routine by season or age (Bergfeld, 2021)
