Your skin pH balance could be one reason why your face suddenly feels tight or stings when you apply products that never bothered you before.
Really? The pH balance?
It’s true. Your skin has its own chemistry, and habits that may feel healthy to you right now may actually be messing up that chemistry, throwing your skin off. And that can lead to redness, irritation, dryness, and reactions you never expected.
Below, we share the five most common pH-disrupting things you may be doing right now, and what to do instead to be sure your skin stays healthy and youthful-looking.
What Is Skin pH Balance?
The pH scale measures tiny charged particles called hydrogen ions. They are far too small to see.
When something has a lot of hydrogen ions, it is called acidic. Lemon juice and vinegar are acidic.
When something has about the same balance of hydrogen ions as pure water, it is neutral.
When something has fewer hydrogen ions than pure water, it is called alkaline. Soap and baking soda fit in this category.
The pH scale runs from 0 to 14. Acidic things fall below 7. Neutral is 7. And alkaline things fall above 7.
Your skin is naturally a little acidic, usually having a pH around 4.5 to 5.5, though the number varies by person and body area. This slightly acidic environment helps it hold in moisture and protect itself from germs. It’s called the “acid mantle” and is made up of natural oils and fatty acids.
A 2024 scientific review of the skin acid mantle found that skin pH affects barrier function, inflammation, and the skin microbiome. Another study on natural skin-surface pH found that skin with a pH below 5 had better moisture, less scaling, and stronger barrier measurements than skin with a pH above 5.
Researchers have also found higher average skin pH in groups of people with acne and atopic eczema. This doesn’t mean pH alone causes these conditions, but it does show that pH is connected to barrier health.
Of course, you can’t be perfect with your skin every day and it usually recovers easily from temporary changes. The trouble occurs when your regular skin care routine disturbs the surface on a consistent basis, throwing off the pH and causing repeated stress.
Why does pH matter in skincare products?
The pH of skincare products affects the barrier function.
Products that are balanced with skin’s natural pH help prevent trans epidermal water loss (TEWL), and help maintain the skin’s microbiome balance, inhibiting harmful bacterial and supporting beneficial flora.
pH balanced products also help avoid sensitivity and risk of irritation.
CV Skinlabs products are formulated to restore and maintain your skin’s natural pH level to promote a healthy and radiant complexion. Our pH-balanced skincare products ensure optimal barrier function and microbiome health, minimizing dryness, irritation, redness, inflammation, and damage, while maintaining skin health and glow!
Skin pH Balance Mistake #1: Using Harsh Soap
This is one of the most common errors people make that messes up the skin’s pH level. Traditional soap is usually alkaline, which means it can raise the skin’s surface pH while removing oils that help protect the barrier.
If your face feels tight, dry, or itchy after washing, your cleanser may be stripping more than dirt and makeup.
One review of pH and cleansing found that soaps and cleansers can change skin-surface pH and affect the barrier and skin microflora.
Instead: Use a mild facial cleanser instead of body soap on your face. A cream or gentle, low-foaming formula is usually better for dry or sensitive skin.
Skin pH Balance Mistake #2: Washing Too Often
Even water can temporarily change the pH at the skin’s surface. One study found that plain tap water, which was generally alkaline at the European study sites, raised skin pH for up to six hours before it returned to its usual level.
Water measures differently depending on where you get it, so this effect will vary, but in general, it helps to understand that even plain water can disrupt the skin’s pH level temporarily.
That means you have to be balanced in how much you wash your skin. An even bigger concern is washing a lot with hot water or a strong cleanser. Each wash requires the skin to recover again.
Instead: You may not have to wash your face more than twice a day. Twice a day is normal, and most people won’t need to wash more than that unless they’re working out or sweating a lot outside. Use lukewarm water, make gentle movements with your fingers or a soft cloth, and skip rough cloths and cleansing brushes if your skin is sensitive.
Skin pH Balance Mistake #3: Overdoing Acids
Glycolic, lactic, and salicylic acids can remove dull surface cells and clear clogged pores. They are naturally acidic, which is why they work for exfoliation.
But the type of acid, its concentration, the full formula, and how often you use it can all play into how it affects your skin. Research shows that both pH and concentration can affect how acids may impact your skin.
You can make it worse when you stack an acid cleanser, exfoliating toner, peel, and retinoid all in the same day or even the same week, depending on how your skin reacts.
Instead: Start with one exfoliating product once or twice a week. Cut back if your skin burns, flakes, or reacts with redness and hives.
Skin pH Balance Mistake #4: Using DIY Remedies
You might be a fan of natural ingredients and DIY solutions, but just be careful, because every natural ingredient isn’t good for your face, and some may actually hurt it.
Baking soda, for example—which is often recommended as a home remedy—is alkaline and will disturb your pH balance. Lemon juice, which is also recommended in social media beauty videos, is strongly acidic, as is vinegar. These ingredients can push skin far outside its normal range and may cause irritation, redness, and reactions.
In a small study of diluted apple cider vinegar soaks, for instance, researchers found that the treatment didn’t improve the skin barrier and irritated most participants.
Instead: Skip TikTok and other social media remedies that promise to “detox” or reset skin overnight, as they are risky and may harm your skin.
Stick with professionally formulated products that are pH-balanced for skin, like those from CV Skinlabs. Our products are all formulated to match the skin’s natural pH to balance and maintain barrier health and achieve a beautifully balanced complexion.
Skin pH Balance Mistake #5: Trusting the Label Alone
Speaking of pH-balanced products, be careful. A product that is labeled as pH-balanced can still irritate your skin, particularly if it has other harsh or irritating ingredients in it.
Cleansers at a skin-friendly pH can still cause dryness when they contain harsh cleansing agents. So you have to look at the entire formula, which means turning the product over and reading the ingredient list.
Instead: Choose gentle formulas that are fragrance-free and make sure they don’t have any harsh ingredients. (Check out our list of ingredients to avoid here.) Then use it in a small area and see how your skin feels. If you notice burning, itching, or tightness, think about changing that product.
How to Support Skin pH Balance Every Day
To avoid these mistakes and keep your skin’s pH level more consistent, try these tips:
- Check the skin after cleansing: How does it feel? Dryness, redness, flaking, or sensitivity means you need a gentler cleanser.
- Simplify your routine: Particularly if your skin is already irritated, try simplifying your routine for a couple of weeks. Use a gentle cleanser, tone, and moisturize, and pause any scrubs, peels, acids, and other strong active ingredients until your skin calms down.
- After cleansing, cool: Mist on our Rescue + Relief Spray to cool, hydrate, and soothe sensitive skin, restoring balance and comfort.
- Moisturize with a nourishing product: After toning, apply our Calming Moisture to replenish moisture and help support your skin barrier, calming sensitivity and irritation.
- For the body, apply our Body Repair Lotion after bathing while skin is still damp.
- Dab our Restorative Skin Balm onto rough or cracked areas to help seal in moisture and maintain a healthy skin barrier.
When your skin recovers, you can add back in a little exfoliation, maybe an anti-aging serum here and there, etc. Go slow and allow your skin to adapt. If you notice stress, back off.
Skin pH balance is only one part of healthy skin, but it helps the barrier do its job. Treat that delicate surface with care, and your skin has a better chance to stay soft, calm, comfortable, and naturally radiant.
