"Alkaline products strip away natural oils and disrupt the skin barrier, increasing transepidermal water loss," said Dr. King.
"The key concept here is the importance of the skin barrier function, which is influenced by pH, as well as other factors," said Hadley C. King, MD, FAAD.
"The microbiota on the skin play an important role in the barrier function," said Dr. King.
This is why you should be careful when using acids like alpha hydroxy, retinoic, beta hydroxy, and amino fruit — they can weaken the skin’s natural defenses if overused.
As you probably guessed, when your skin barrier function is disrupted or the pH is thrown off, it can leave to skin problems like irritation and breakouts.
"Products that support healthy and diverse skin microbiota are also beneficial to the skin barrier".
"The acid mantle is made up of sebum (free fatty acids), which mixes with lactic and amino acids from sweat to create the skin’s pH".
A lot of factors can influence the barrier function of the skin.
"The microbes on the skin impact the way it looks and feels, and its ability to serve as a barrier between your body and the outside world".
It applies to more than just experiments; keeping your skin’s natural pH level in check is important for maintaining healthy and happy skin.
Healthy microbiomes can fight against external and environmental factors, as well as keep inflammation in check and promote healthy skin healing.
If you suspect your skin barrier function is compromised, Dr.
"Soothing agents to reduce skin irritation and inflammation can also be helpful, such as sea whip extract," said Dr. King.
Your skin barrier acts as a shield for your skin and keeps moisture in and bacteria out.
"The outermost protective layer of the skin is referred to as the acid mantle," said Dr. King.
In addition to microbiomes, sweat, oil, and skin-care products can all disrupt your skin’s pH level.
King recommended using humectants like glycerin and hyaluronic acid to hydrate and barrier restoring lipids like ceramides and petrolatum to lock in moisture and restore the barrier.
When stocking your skin-care routine, she recommended sticking to gentle moisturizers, like the GoodJanes H2O My God Water Cream that don’t contain actives like alpha or beta hydroxy acids or fruit acids or retinol — leave those to your serums and topical treatments to ensure you don’t overdo it.
Your skin is more complex than you may realize — consider how easy it is for a breakout to come on if you touch your face, or for your skin to get irritated if you add a new product into your routine, or for the weather to make your face dry.
