Effects of Benzoyl Peroxide on Pores What You Need to Know 

Benzoyl Peroxide is a topical OTC BHA treatment that is FDA-approved for the treatment of acne vulgaris. It has antibacterial properties and mild sebostatic and keratolytic effects.

This means that it helps to slow down oil production in the skin and it mildly exfoliated dead skin cells.

However, since acne-prone skin tends to have bigger pores, a common question I get is what does benzoyl peroxide do to your pores themselves? 

What Does Benzoyl Peroxide Do To Pores

Benzoyl Peroxide helps to unclog pores and return them to their normal size. 

Benzoyl peroxide will not directly shrink your regular pores and make them smaller. However, in people with oily or acne-prone skin, pores are generally bigger and open. The bigger the pores are, the more oil and become trapped, and the bigger clogs can get. 

Sometimes, dermatologists and skin care professionals can refer to clogged skin as “congested skin”. This usually refers to bumpy skin with clogged pores that can lead to acne.

How Do Pores Get Clogged

Our pores end up being blocked up by not only oil (sebum), but also bacteria, inflammation, and dead skin cells. These results in blackheads, whiteheads, open/closed comedones, and even folliculitis (infected hair follicles) in some areas.

How Does Benzoyl Peroxide Work

When benzoyl peroxide is applied to the skin, it:

  • Kills bacteria,
  • Reduces inflammation,
  • And unclogs the pores by breaking up and lifting the oil and dead skin cells out of them. 

As the pores are no longer clogged and inflamed, they eventually start to shrink back to their normal size. Constant use of benzoyl peroxide helps to control the amount of oil being produced and secreted through the pores and prevents any more clogs. This helps the pores to retain their normal size.

How To Use Benzoyl Peroxide For Clogged Pores

The easiest way to use benzoyl peroxide on your skin for pores is as a wash or soap. However, it can also be used as a topical gel, cream, lotion, serum, pad, mask, peel, etc. 

Since you have pores EVERYWHERE, it is much easier to spread around and use a wash or soap than to use a gel, cream, or serum. You can cover more surface area. The product is also absorbed faster and easier into the skin.

Each kind of formula will have specific instructions on how often you can use it to provide the most benefits and least side effects. However, remember that all skin is different so you may need to adjust your routine based on your skin’s reaction until you get it right.

Salicylic Acid Or Benzoyl Peroxide: Which Is Better For Pores

Both salicylic acid and benzoyl peroxide are BHAs that unclog pores and reduce oil production on the skin. However, the best one for you will ultimately depend on your skin. 

Since clogged pores lead to acne, how well either of these treatments works will depend on the kind of acne you have.  

Generally, salicylic acid is best if you have whiteheads and blackheads. However, benzoyl peroxide is better if you have inflammatory acne (pus-filled, bacterial). The condition of your pores will depend on your treatment’s ability to keep your pores clear and acne-free.

Side Effects Of Using Benzoyl Peroxide

Benzoyl peroxide can cause skin purging, irritation, and allergic reactions. 

If you have never used benzoyl peroxide before I recommend seeing a dermatologist first. If used incorrectly (too often or in too high concentrations) your skin can become too dry and irritated. 

Benzoyl peroxide allergies are also possible so you should do a patch test to see how your skin will react before using the treatment on your face and other large surface areas.

Skin purging is also a regular, expected reaction for people who are using benzoyl peroxide for the first time or after a long time.
