BHA and panthenol make an unusual pair. BHA, which is salicylic acid, is an exfoliant that loosens the dead skin and oil sitting on the surface and inside pores, so the skin looks smoother. Panthenol, which is provitamin B5, follows it and keeps the freshly cleared surface feeling comfortable. In short, the BHA does the sweeping and the panthenol does the soothing.
What is BHA, and how is it different from AHA?
Salicylic acid is a beta hydroxy acid, or BHA. Glycolic acid and other AHAs dissolve in water, so they work mainly on the surface. Salicylic acid is oil-soluble, which means it can move into the oily lining of a pore. A 2015 review in Clinical, Cosmetic and Investigational Dermatology describes it as a peeling agent that loosens the connections between skin cells, so the outer layer sheds more easily.
That oil-friendly action is why it's often used on oily skin with visible pores.
If you've already tried AHAs for texture, our glycolic acid texture guide explains where they fit, and why BHA is the one to reach for when oil is the bigger part of the problem.
What does panthenol add?
Panthenol is vitamin B5 in a form your skin can use. It draws water into the surface and leaves the skin feeling soft instead of tight. That matters after an exfoliant.
You're not trying to strip more buildup at that point, you're trying to make the skin feel settled. Reviews of topical dexpanthenol point to its moisturising and barrier-supporting role, which is why it suits this job.

How to layer BHA and panthenol
The order matters more than the products. Here is a simple routine:
- Cleanse, then pat your face dry.
- Apply a BHA toner or serum to the whole face, avoiding the eye area.
- Wait until the skin feels dry, usually a minute or two.
- Apply panthenol, or a moisturiser that contains it.
- In the morning, finish with sunscreen. Exfoliating acids can make skin more sensitive to the sun.
Start with two or three nights a week and build up only if your skin stays calm. If your skin feels tight after cleansing before you even get to the BHA, our guide to why skin feels tight after washing is worth reading first.
Will it sting?
A light tingle on first use is common with BHA. Stinging that keeps going, or skin that turns hot and red, means stop and go back to panthenol alone for a while. Don't use BHA on the same night as a strong retinol while you're getting used to it. Our guide to why skincare stings and leaves skin red covers the usual causes.
What results look like
The changes you can expect are about appearance. Over several weeks, the surface may look smoother and more even, and pores may look less noticeable. BHA won't change how big your pores are, so it helps to keep expectations realistic. Our guide to making pores look smaller explains what changes the look and what doesn't.
Who this pairing suits
BHA with panthenol suits oily skin with visible pores that doesn't get irritated easily. If your skin is dry or reactive, start with panthenol alone and skip BHA for now. Dry, tight skin usually needs water first, as our dehydrated vs dry skin guide explains.
FAQ
Can I use BHA and panthenol every day?
Most people start with two or three nights a week and increase only if their skin stays calm. Panthenol can be used every day.
Does BHA make skin more sensitive to the sun?
Exfoliating acids can make skin more sensitive to sunlight, so use a broad-spectrum sunscreen every morning when you use BHA.
Should I apply BHA before or after panthenol?
Apply BHA first, let the skin dry, then apply panthenol. The BHA works on the surface and the panthenol comes in afterwards to keep it comfortable.
