Can You Use Benzoyl Peroxide With Retinol?

Retinol and Benzoyl Peroxide are two heavy-duty heavy-hitters, with noticeable impact. You may find that these two skincare ingredients are often recommended for acne: benzoyl peroxide has strong anti-bacterial properties, whilst retinol is great at renewing the skin. But with great power comes great responsibility—these two are not for the faint of heart.

Can You Use Benzoyl Peroxide With Retinol?

Yes—but not at the same time, and not for every skin type. Only with a proper strategy and lots of skin barrier support.

Benzoyl peroxide and retinol are two of the most powerful over-the-counter acne treatments available. Each works in different ways—benzoyl peroxide is antibacterial and targets surface acne, while retinol increases cell turnover and treats breakouts from within. Used together, they can form a powerful combination against stubborn acne, clogged pores, and uneven texture.

However, there’s a catch: both ingredients can be harsh and drying, especially when used incorrectly.

The issue lies in how these ingredients interact. Benzoyl peroxide is known to oxidise retinol, which can reduce its effectiveness. On top of that, both are drying and potentially irritating—especially during initial use.

Still, dermatologists often prescribe both—just not simultaneously. By spacing them out in your routine, you can get the benefits of both without overwhelming your skin.

Key concerns:

• Irritation risk: Redness, flaking, stinging, and peeling can occur.
  
  
• Retinol degradation: Benzoyl peroxide can reduce the efficacy of retinol if layered.
  
  
• Compromised skin barrier: Using both too often may weaken the skin’s protective layer.
  

Without a thoughtful routine, combining them can lead to irritation, flaking, and inflammation that does more harm than good. That doesn’t mean you can’t use both—but you need to be strategic about when and how.

What Does Benzoyl Peroxide Do For Skin?

Benzoyl peroxide (BPO) is a powerful acne-fighting ingredient that kills acne-causing bacteria (Cutibacterium acnes) on the skin. It also has mild exfoliating properties and helps remove excess oil and dead skin cells from the surface, reducing the likelihood of clogged pores and breakouts.

It’s often used in spot treatments, cleansers, and creams and is especially effective at treating inflammatory acne like pustules, cysts, and nodules.

Key benefits of benzoyl peroxide:

• Kills acne-causing bacteria: Reduces inflammation and stops acne at its root.
  
  
• Unclogs pores: Prevents blackheads and whiteheads by removing dead skin.
  
  
• Controls excess oil: Helps reduce sebum production over time.
  
  
• Minimises new breakouts: Keeps skin consistently clear with continued use.
  
  
• Works quickly: Can show visible improvements in a few days.
  
  

Best for:

• Oily or acne-prone skin
  
  
• Inflammatory acne (red, swollen pimples)
  
  
• Body acne (chest, back, shoulders)
  
  
• Teens and young adults with hormonal acne
  
  

Common concentrations range from 2.5% to 10%, but higher percentages aren't always more effective and can be more irritating.

What Does Retinol Do For Skin?

Retinol is a vitamin A derivative that works deeper in the skin to stimulate cell turnover, fade post-acne marks, and boost collagen. It doesn’t directly kill acne bacteria but clears clogged pores and supports healthier skin regeneration, making it ideal for both active acne and long-term skin repair.

While retinol is often used for anti-ageing, it’s also incredibly effective for preventing acne and improving overall skin tone and texture.

Key benefits of retinol:

• Boosts cell turnover: Removes dead skin and unclogs pores.
  
  
• Fades acne scars and pigmentation: Helps with post-inflammatory hyperpigmentation.
  
  
• Smooths texture: Reduces rough patches and bumpy skin.
  
  
• Minimises fine lines: Stimulates collagen for firmer skin.
  
  
• Improves tone: Brightens dullness and reduces blotchiness.
  
  
• Prevents future breakouts: Keeps pores clear when used consistently.
  
  

Best for:

• Mature skin with breakouts
  
  
• Acne-prone skin with lingering marks
  
  
• Dull or rough complexions
  
  
• Post-acne pigmentation or scarring
  
  

Retinol should be introduced gradually—start with a low-strength formula (0.25–0.5%) and use it 2–3 times per week before increasing frequency.

How to use benzoyl peroxide and retinol safely

1. Alternate use (best for most people)

Use benzoyl peroxide in the morning and retinol at night. This separation reduces irritation and prevents the ingredients from interfering with each other.

A.M. Cleanser → benzoyl peroxide → moisturiser → SPF
P.M. Cleanser → retinol → moisturiser

A.M.

P.M.

2. Alternate days

Use benzoyl peroxide and retinol on different nights. For example:

• Monday, Thursday – Benzoyl peroxide
  
  
• Tuesday, Friday – Retinol
  
  
• Wednesday, Weekend – Barrier support (ceramides, vitamin B5, pathenol, hyaluronic acid)
  

Monday, Thursday

Tuesday, Friday

Wednesday, Weekend

3. Use a wash-off BPO product

Opt for a benzoyl peroxide cleanser instead of a leave-on treatment. Cleansers are less likely to dry the skin and can be rinsed off before applying retinol at night.

4. Buffer retinol

Use a moisturiser before and after applying retinol (the “moisture sandwich” method) to reduce irritation and protect your skin barrier.

Tips for success

• Start slow: Introduce one active at a time, starting 1–2 times per week.
  
  
• Hydrate consistently: Use hyaluronic acid and ceramide-rich moisturisers.
  
  
• Avoid other harsh ingredients: No scrubs, peels, or AHAs/BHAs in the same routine.
  
  
• Use sunscreen daily: Both ingredients increase sun sensitivity.
  
  
• Watch for signs of overuse: Tightness, excessive peeling, or prolonged redness means it’s time to pull back.
  
  

FAQs

Can I use benzoyl peroxide and retinol on the same day?
Yes, but not in the same routine. Use benzoyl peroxide in the morning and retinol at night to avoid deactivating the retinol and overwhelming your skin.

Will benzoyl peroxide cancel out retinol?
Benzoyl peroxide can oxidise and deactivate certain types of retinol, especially older or unstabilised formulas. Spacing out application is the best way to avoid this.

Can I use benzoyl peroxide cleanser with retinol at night?
Yes—this is one of the safest ways to use both. Since the benzoyl peroxide is rinsed off, it’s less likely to irritate or interfere with your retinol.

Is it safe for sensitive skin?
Sensitive skin types should proceed with caution. Use low concentrations, avoid layering, and prioritise hydration and barrier repair.

Which should I start with—benzoyl peroxide or retinol?
If acne is your main concern, start with benzoyl peroxide. If you're more focused on acne plus ageing or pigmentation, retinol may be better. Whichever you choose, introduce it slowly before adding the second.
