However, have you ever considered the pH level of your skin? Much like the need for balance in life, maintaining the right pH balance in your skin is essential for healthy and happy skin.
Feeling perplexed? Curious about what this means or how to take care of your skin’s pH level? Continue reading to discover why understanding and caring for your skin’s pH balance is crucial.
What Is Skin pH Level?
Your skin thrives when it maintains a delicate equilibrium. You may have come across the term ‘pH balance’ in skincare brand advertisements and dismissed it as a marketing tactic. However, this is an aspect you should pay attention to.
The abbreviation ‘pH’ stands for ‘potential of hydrogen.’ Essentially, it measures the concentration of hydrogen ions in any substance. Developed in the early 1900s by Danish chemist S.P.L. Sorensen, the pH scale quantifies acidity and alkalinity, ranging from 0 (most acidic) to 14 (most alkaline).
Your skin boasts an acid mantle, a protective barrier formed as your skin produces sebum and breaks down fatty acids. This acid mantle plays a vital role in maintaining the health and moisture of your skin by warding off harmful germs and toxins.
Did You Know?
In 1892, Heuss discovered the skin’s surface’s acidic composition. In 1928, Schade and Marchionini coined the term “Säuremantel,” or “acid mantle,” to describe the natural acidic composition of the stratum corneum (the outermost layer of the skin).
Your skin is at its best when its acidity and alkalinity are balanced. Disturbing this balance can lead to skin issues. So, let’s explore why you should be mindful of your skin’s delicate pH balance
Why Should You Care About Your Skin pH?
When the acid mantle of your skin becomes too alkaline, your skin can become sensitive and dry. You might experience inflammation and even signs of aging due to certain enzymes that can degrade your collagen levels. This often occurs when you frequently change your skincare products.
Using products with a high pH (alkaline) can impact the permeability of your skin, making it susceptible to skin issues, irritants, and microorganisms. Elevated skin pH levels may contribute to skin problems such as ichthyosis vulgaris, atopic dermatitis (eczema), candidal intertrigo (a skin infection caused by the yeast Candida albicans), tinea pedis (Athlete’s foot), and acne (P. acnes thrives when skin pH is between 6 and 6.5). High pH levels can also accelerate the skin’s aging process.
Quick Tip
Opt for skincare products with a pH of 5.5, as they are ideal for your skin. Products with a high pH (8 to 14) may strip away natural oils, while those with extremely low pH (below 4.5) may irritate your skin.
But what is the ideal pH level for your skin, and how can you determine if it’s balanced? Let’s delve into these questions.
pH levels of various skin types
| Skin Type | pH Range |
|---|---|
| Normal Skin | 4.5 to 5.5 |
| Combination Skin | Varies (different areas may have different pH levels) |
| Oily Skin | 4.0 to 5.5 |
| Sensitive Skin | 4.0 to 7.0 (more sensitive to pH fluctuations) |
| Neutral pH | 7.0 (e.g., Pure Water) |
|---|---|
| Healthy Skin | Can vary between acidic and neutral based on individual factors |
| Alkaline pH | pH Range |
|---|---|
| Dry Skin | 6.0 to 7.0 |
| Aging Skin | 6.0 to 7.0 (tends to increase in pH due to reduced acidity) |
What Is The Ideal Skin pH? How Can You Find Out Your Skin’s pH?
Ideally, your skin should be slightly acidic, with a pH level of 5.5. However, a range between 4.8 and 6 is also acceptable. This range ensures that your skin’s barrier function remains active, protecting you from toxins, bacteria, and external factors.
Measuring your skin and hair’s pH directly can be challenging. However, a dermatologist can assist you in this regard by using a pH meter to thoroughly analyze your skin’s surface, detect any pH level shifts, and evaluate your skin’s condition and any ongoing skin issues.
Nonetheless, your skin often provides signs when its pH levels are imbalanced. Look out for signs like excessive oiliness, dry patches, redness, rashes, eczema, psoriasis, acne, or visible signs of aging such as fine lines, wrinkles, and sagging skin.
This study emphasizes the importance of pH in nature and human physiology, with different organs having pH ranges from 1 to 8. The stratum corneum, with a physiological pH of 4.1-5.8, is influenced by various factors. Initially recognized for its antimicrobial properties, pH also affects skin barrier function, lipid synthesis, epidermal differentiation, and desquamation. pH regulation impacts enzymes and proteases involved in ceramide metabolism and epidermal differentiation. Disruptions in the skin barrier lead to increased pH, observed in inflammatory and epidermal-related skin conditions. Restoring pH through topical acidification promotes a healthy microbiota, repairs the skin barrier, induces epidermal differentiation, and reduces inflammation.
All these signs are indicative of damage to your skin’s acid mantle. How did it become compromised? Several factors and habits can disrupt your skin’s pH levels. Continue reading to discover more about these factors.
Factors Affecting Your Skin pH Levels
Age: As you age, your skin becomes more alkaline, leading to issues like wrinkles, fine lines, and pigmentation. The pH of the epidermis increases from 5 to 5.5-6 as you grow older. This shift can harm your skin’s protective function and reduce hydration, affecting the natural skin microbiome.
Excessive Sun Exposure: Prolonged exposure to harmful UV rays weakens your skin’s acid mantle, making it more alkaline. This can result in problems such as pigmentation, dullness, and acne. Even sun exposure during your teenage years can initiate this process, with UVA light penetrating the skin to reach the dermis.
Using Bar Soap On Your Face: Bar soaps are major culprits behind disrupting your skin’s pH balance. Their pH level is typically around 9, significantly higher than the normal pH of skin. Applying bar soap on your face leaves an alkaline residue that makes your skin susceptible to issues and damage.
Dietary Habits: Your diet directly impacts your skin’s pH level. Excessive acidity in your system, caused by too much caffeine, sugar, yeast (found in bread and baked goods), processed grains, and alcohol, can affect your skin.
Other Skin Care Habits: Certain skin care habits can disturb your skin’s pH level. These include using hot water for cleansing, excessive scrubbing, using harsh cleansers, and taking long showers. These practices strip away your skin’s protective acid mantle.
How To Keep Your Skin pH Level Balanced
Restoring your skin’s pH level involves repairing its barrier function, maintaining skin hydration, and ensuring radiance. Here are steps you can take:
Eliminate Soaps And Harsh Cleansers: Avoid using bar soap on your face and opt for gentle, pH-balanced skin care products. Always choose products that list their ingredients on the packaging and use lukewarm or room temperature water for cleansing.
Use Apple Cider Vinegar: Apple cider vinegar is effective in regulating skin pH levels. Dilute it with water before application. Mix half a cup of apple cider vinegar with four cups of water, store it in a spray bottle, and use it as a toner.
Use Good Oils And Moisturizers: Aging reduces your skin’s ability to produce natural oils and sebum, damaging the acid mantle and pH balance. Use gentle moisturizers and oils like jojoba, argan, coconut, and olive oils to keep your skin hydrated and rebuild its moisture barrier.
Use Acids Carefully: Ingredients such as retinoic acid, alpha and beta hydroxy acids, and amino fruit acids are beneficial but must be used properly to avoid damaging your skin’s defense. Over-the-counter products containing these acids are typically safe, but discontinue use if your skin becomes dry, red, or sensitive.
Use Sun Protection: Regular sunscreen application is crucial for maintaining skin pH and protecting it from further damage. Opt for a broad-spectrum SPF sunscreen and apply it daily to shield your skin from the sun’s harmful effects.
Use Topical Antioxidants: Topical antioxidants strengthen skin cells, protect against environmental damage, and promote proper functioning. Vitamin C, available as L-ascorbic acid, is known for balancing skin pH and can be safely used on the skin, provided it’s not used alongside other acidic products.
Change Your Diet: Incorporate antioxidant-rich foods such as leafy vegetables (especially spinach) and low-sugar fruits (like berries, bananas, and watermelon) into your daily diet. Avoid processed foods, which increase body acidity and can affect skin pH. Include salads and reduce sugar intake for healthier skin.
