pH in skincare has become a popular topic in recent years for good reason. People are becoming mindful that the health and look of their skin can be significantly affected by the low pH cleanser they use, or if they use them at all. Using the wrong cleanser might make your skin dry, irritated, and break out, which can make it harder for your skin to protect itself. But do acidic products work better? Let's look at what science has found!
What is pH & Why Does It Matter for Your Skin?
The pH scale, which goes from 0 (most acidic) to 14 (most alkaline), with 7 representing neutrality (water), indicates how acidic or alkaline a substance is. The pH of your skin is naturally slightly acidic, at about 5.5. This level of acidity is important for keeping your skin healthy.
The acid mantle is the thin coating of oils, sweat, and dead skin cells that protects this acidic environment. The acid mantle is the first line of defence for your skin. It keeps harmful germs, pollutants, and moisture from getting in.
Using a pH-balanced cleanser keeps this barrier intact instead of hurting it. When you protect your acid mantle, your skin stays strong, moisturised, and less likely to get irritated.

Acidic vs Alkaline: What’s the Difference in Skincare Products?
Most regular soaps and cleansers have a high pH, usually between 9 and 11. These alkaline products can hurt your acid mantle, which can make your skin feel tight, dry, and even inflamed, which can cause breakouts.
On the other hand, low-pH cleansers, which usually have a pH between 4.5 and 6, gently balance and keep your skin's natural acidity. These cleansers help keep your skin from being dry, soothe inflammation, and help keep your barrier strong.
Benefits of Low pH Cleansers (Backed by Research)
-
Keep your microbiome in good health: The healthy bacteria on the skin thrive in a slightly acidic environment, which helps to keep bad bacteria at bay.
- Reduce acne & inflammation: Acidic skin levels stop germs that cause acne from growing, which calms redness and breakouts.
- Prevent drying and dehydration: Low pH cleansers don't strip away natural oils, so your skin stays smooth and supple.
- Prevent premature aging: A balanced skin barrier protects against harm from the environment that causes wrinkles.
- Promote better absorption of serums: When the skin barrier is strong, exfoliants and actives can easily penetrate skin.
The Lumiere Low pH Diamond Essence Cleanser is a gentle but effective cleanser that is balanced in pH. It is a gentle cleanser that gently removes impurities from your skin while hydrating and restoring its natural pH balance.
Are Acidic Products Better for All Skin Types?
Low-pH products are usually beneficial for people with sensitive, oily, or acne-prone skin. The acidity of the products helps control extra oil on sensitive skin, decreases inflammation, and stops irritation.
However, specific highly acidic actives, such as AHAs and BHAs, which have a lower pH of about 3-4, must be used with caution. They are excellent for brightening and exfoliating, but if used excessively or in combination with other harsh products, they may be too strong and can irritate or make your skin overreact.
It's a good idea to seek labels that state "pH balanced" or "low pH" to make sure your products won't disrupt the acid mantle on your skin.
How to Build a Low pH Skincare Routine (Step-by-Step)
You can't simply pick low-pH products to make a balanced skincare routine. You must layer the right ingredients on top of each other in the right order:
-
Step 1: Gentle Low pH Cleanser
Start your routine with a cleanser like the ACELABS Lumiere Low pH Diamond Essence Cleanser. It cleans your skin and keeps its pH level stable without stripping it, which gets it ready for the next steps.

Step 2: Toner
Pick toners that don't have alcohol in them and will balance your skin's pH while relaxing and moisturising it.
-
Step 3: Serums
Use serums that are made to help the skin barrier and add moisture. Hyaluronic acid and niacinamide are two ingredients that are great for skin health.
-
Step 4: Moisturizer and SPF
Use a moisturising cream to seal everything in. Always put on sunscreen last to protect your skin from UV damage.
The goal is not only to maintain optimal skin pH but also to create a gentle, effective skincare routine.
Expert Tips to Choose the Right pH for Your Skin Products
- Choose cleansers that have a pH of 4.5 to 5.5, which is very close to the natural level of your skin.
- Avoid cleansers that are alkaline or contain soap, as these usually have a pH level above 9.
- Use pH strips to test your products at home, just for fun or to understand your products better.
- Find acidic ingredients in the list, including citric or lactic acid, which help with exfoliation while maintaining a low pH.
Conclusion
Using a cleanser with a lower pH is better for your skin, and science backs this up. By using products that protect your acid mantle, you can keep your skin barrier strong and moisturised, which will help prevent it from irritants and early ageing.
