What pH Level is Your Sunscreen, and Why Should You Care? – KINeSYS Performance Sunscreen Australia


What pH Level is Your Sunscreen, and Why Should You Care?

Have you ever wondered what the pH level of your sunscreen is? Or why you should care? PH levels are often mentioned in relation to skincare and beauty products, but when it comes to sunscreen, this factor is often overlooked. In this article, we take a closer look at pH levels and what they mean for you when it comes to wearing sunscreen (or when it comes to your skincare routine).

What is pH?

PH is a pretty fascinating subject, although it’s mired in confusion and misinformation. ‘Potential hydrogen’ or pH, refers to the acid-alkaline ratio of a substance. Anything from the soil in the ground to the food you eat, to the water you drink, has a pH level. The pH scale, from 0 to 14 refers to how acidic or alkaline a substance is, where 0 is the most acidic, 14 is the most alkaline, and 7 is neutral. When it comes to the pH level of your own skin, this generally sits anywhere between 4.5 and 5.5, meaning it’s slightly acidic.

When we are born, or skin has a naturally neutral pH level. After a couple of weeks, this moves to the acidic side of the scale. As we grow older, the pH level of our skin tends to rise, although it will always remain slightly acidic. That’s why the pH level of our skincare grows even more important with age.

Which pH levels are safe for your skin?

Your skin is slightly acidic due to its need to protect you against the elements. The skin’s natural protective membrane is acidic, as this is better for fighting off infections, pollutants, and other damaging factors. Therefore, when skin is exposed to alkaline products, or its pH is affected by environmental factors such as the sun, water, or pollution, it tends to become dry, irritated or flaky.

When choosing beauty products, the pH levels will affect the way that your skin reacts. A beauty product – whether it’s makeup, moisturiser, or sunscreen – with an alkaline pH level will not only be uncomfortable to wear, it will potentially cause irritation or long-term damage to your skin.

Continuous use of non-suitable skincare products which are too alkaline can also affect the enzymes in your skin. The enzymes responsible for breaking down collagen, for example, are activated by alkaline environments and therefore thrive when skin is exposed to alkaline products. This breakdown of collagen can cause premature ageing and wrinkles, loss of plumpness, and can even go on to cause eczema! Using products with suitable pH levels is therefore a powerful tool in preventing premature ageing, and in taking care of your skin’s health and natural defences.

What are the pH levels of sunscreen?

As pH levels are not often discussed when it comes to sunscreens, knowing their levels can be tricky. Choosing a sunscreen with a pH level in the safe range for skin is incredibly important for maintaining healthy, radiant skin, especially as we get older. Many brands aren’t transparent about their products’ pH levels, so be sure to choose a brand whose pH information is available.

At KINeSYS, we’re not just concerned with helping you protect your skin against the sun’s harmful rays. We’re also dedicated to developing products which are great for your skin’s health and fit easily into your daily routine. Our spray sunscreens are oil-free and suitable for use under or over your makeup, making them the perfect addition to your skincare and beauty routine.

What’s more, all KINeSYS sunscreens have pH levels of between 4.9 and 5.10, meaning they won’t affect the natural pH levels of your skin.

Our spray sunscreens are also safe for use with sensitive skin and are free from common irritants such as colorants, fragrance (fragrance-free products) and sulphites. For more detailed information about the pH levels of your favourite KINeSYS sunscreen, see the table below.

Why are KINeSYS sunscreens so great for your skin?
