For skincare noobs who may wonder what benzoyl peroxide is – it’s like an antiseptic that kills bacteria and is often used as a topical medication to treat acne and rosacea. In fact, benzoyl peroxide for skin can be used to bleach skin, remove dark spots and if approved by your dermatologist, it’s good for the skin. Inside the intriguing world of skin science, are our daily skincare products that are made up of certain active acids and ingredients that tackle one or more skin concerns. One such ingredient is benzoyl peroxide.

What Does Benzoyl Peroxide Do to Skin?

This anti-inflammatory fix opens up clogged pores and releases oxygen, thereby killing acne-causing bacteria on the skin. Skincare experts swear by this ingredient and recommend it for treating a number of common skin concerns. As the potent component found in most acne fighting products in the market, benzoyl peroxide should be in every skincare junkie’s vanity. However, with benzoyl peroxide you may want to take things slow by using the lowest percentage and applying it on alternate days. A good practice can be to first wear your moisturiser and then go with your BP spot treatment to avoid any irritation. Having said that, here are 4 common skin concerns that can be treated using benzoyl peroxide.

1. Clears Acne & Prevents Breakouts

Clears Acne & Prevents Breakouts

Benzoyl peroxide helps banish acne and pimples as its notoriously famous for drying out the skin. Due to its ability to reduce inflammation, this ingredient is also recommended to those with cystic acne. It can be found in cleansers, lotions, gels, creams and toners. It can also be used for spot treatment. Try it for yourself with Dermalogica’s Breakout Clearing Emergency Spot Fix that will reduce redness and calm the skin. Just dab it onto individual breakouts and see the difference.

2. Fades Dark spots & Acne Scars

No matter how much you try, it is difficult to keep your hands off your face when a huge pimple is sitting on it. But constantly touching the zit can leave behind a stubborn dark spot or scar that can take weeks if not months to fade. Can benzoyl peroxide remove dark spots? Yes, it can! Benzoyl peroxide is that magic ingredient that can help you get rid of these dark spots in no time. With its ability to slough off dead skin cells, dark spots and scars appear less prominent over time.

3. Evens Skin Tone & Lightens Pigmentation

Environmental stressors can cause the skin to look uneven and pigmented. Using benzoyl peroxide topically will give you an even-looking skin tone due to its bleaching properties. Does benzoyl peroxide bleach skin? Yes, benzoyl peroxide has mild bleaching effects, which can help lighten dark spots and hyperpigmentation over time. With regular use, it might also make your skin appear brighter. You can also try Novology Bi-Phasic Hyper Pigmentation Serum. It’s an easy-to-use serum that features Novology patented HNR3 technology with 3.7% Hexylresorcinol, Niacinamide, and Retinyl Propionate – all of which work to tackle dark spots and post-inflammatory marks.

4. Clears Blackheads And Whiteheads

Fun fact: Did you know blackheads and whiteheads are considered non-inflammatory acne? After all, acne breakouts and pimples stem from them. Since benzoyl peroxide has the ability to kill germs and bacteria by unclogging your pores and removing dead skin cells. Applying it on blackheads and whiteheads may in turn prevent acne.

 

Please note: While over-the-counter benzoyl peroxide products can be used to treat mild acne, for moderate and severe acne we suggest visiting a dermatologist who will recommend the right concentration based on your needs.

Possible Side Effects of Benzoyl Peroxide

Possible Side Effects of Benzoyl Peroxide

As a chemical compound, benzoyl peroxide may cause dryness, peeling, redness, or irritation. If you’re someone who has sensitive skin, it’s best to consult your dermatologist before reaching out for it. It increases sun sensitivity as well, so skipping sunscreen after its application is a big no.

Here are the potential side effects of using benzoyl peroxide:

1. Skin Dryness & Peeling

Benzoyl peroxide can dry out the skin, causing flakiness and peeling, especially when first introduced to your skincare routine. It's important to moisturize regularly to counteract this effect.

2. Redness & Irritation

Some people may experience redness, stinging, or irritation, particularly when using benzoyl peroxide on sensitive or broken skin. Start with a lower concentration to minimize discomfort.

3. Increased Sun Sensitivity

Benzoyl peroxide can make your skin more sensitive to the sun, leading to an increased risk of sunburn. Always apply sunscreen during the day when using products with benzoyl peroxide.

4. Risk of Skin Bleaching

Benzoyl peroxide has mild bleaching properties, which can inadvertently lighten hair or fabrics. Be cautious when applying it near your hairline or on clothing to avoid discoloration.

5. Allergic Reactions

In rare cases, benzoyl peroxide can cause allergic reactions, such as swelling, hives, or difficulty breathing. If this occurs, discontinue use immediately and consult a healthcare professional.
