Post Break Out Serum

Post Break Out Serum

Product Description

An oil-free, lightweight serum from Acnecide (the Purifide range) that targets post-breakout marks, redness and uneven texture. It pairs plant-based bakuchiol โ€” a gentle, retinol-like active โ€” with niacinamide and Pro-Vitamin B5 to smooth and brighten post-acne skin and protect the barrier, without clogging pores or adding shine.

Plant-Based Bakuchiol

A gentle, retinol-like active that encourages skin renewal and fades post-breakout marks โ€” without the peeling, dryness or sun-sensitivity of true retinoids.

๐Ÿ”ฌ

Barrier-First Formula

Niacinamide and Pro-Vitamin B5 reinforce the skin barrier, so it refines texture and tone without compromising the skin the way harsher acne actives can.

๐Ÿ’ง

48-Hour Hydration

Humectants such as glycerin and panthenol keep skin balanced and soothed for up to two days per application, even though the base is fully oil-free.

๐Ÿšซ

Oil-Free & Non-Comedogenic

Built for spot- and acne-prone skin: no added facial oils, fragrance or silicones, so it absorbs fast and won't clog pores.

๐Ÿ›ก๏ธ Safety & Compatibility

โš ๏ธ
Pregnancy & Breastfeeding

Niacinamide and panthenol are widely considered safe, but bakuchiol lacks robust pregnancy safety data. Most dermatologists advise caution โ€” check with your doctor before use.

๐Ÿ„
Fungal Acne (Malassezia)

Not fungal-acne safe. It contains esters (coco-caprylate/caprate, caprylic/capric triglyceride) and lysolecithin, which can feed Malassezia yeast.

โœ…
Sensitive Skin

Fragrance-free, alcohol-free and free of common allergens. Bakuchiol is far gentler than retinol, so it suits most reactive skin โ€” patch test first to be sure.

๐Ÿงช
Layering With Actives

Plays well with most routines. Bakuchiol can even be paired with retinol or vitamin C. Introduce alongside strong AHA/BHA exfoliants gradually.

โ˜€๏ธ
Sun Sensitivity

Unlike retinoids, bakuchiol doesn't increase photosensitivity, so it can be used both morning and night. Daily broad-spectrum SPF is still essential.

๐Ÿ 
Reef Safe & Vegan

Free from oxybenzone/octinoxate UV filters and animal-derived ingredients, making it both reef safe and vegan-friendly.

๐Ÿ”ฌ Ingredient Breakdown

๐Ÿงฌ Niacinamide ~4โ€“5% (est.) Proven

Vitamin B3 is the workhorse of this serum. It strengthens the skin barrier, helps regulate oil, calms redness and interrupts pigment transfer โ€” which is what fades post-acne dark marks over time.

  • Research: Reviews of niacinamide report measurable fading of hyperpigmentation and improved barrier function at around 4โ€“5%.
  • Brand study: In a 35-subject user questionnaire, skin was reported as smoother and brighter within one week.
โš ๏ธ
The exact percentage isn't published by the brand; ~4โ€“5% is estimated from niacinamide's position (3rd) on the ingredient list.

๐ŸŒฑ Bakuchiol ~0.5โ€“1% (est.) Promising

A plant-derived compound from Psoralea corylifolia that mimics many of retinol's renewal benefits โ€” smoothing texture and softening marks โ€” but without the irritation, flaking or sun-sensitivity that retinoids can cause.

  • Research: A 2019 British Journal of Dermatology study found bakuchiol comparable to retinol for lines and pigmentation, with less scaling and stinging.
โœ…
Non-photosensitising, so it's suitable for both morning and evening use.

๐Ÿ’ง Panthenol (Pro-Vitamin B5) ~1โ€“2% (est.) Proven

A humectant and skin-soother that draws in moisture, supports barrier repair and eases the tight, irritated feeling that often lingers after a breakout.

  • Research: Panthenol is well-documented to boost hydration and reduce transepidermal water loss, improving comfort in compromised skin.

โš—๏ธ Zinc Gluconate Trace Promising

Zinc helps balance sebum and brings soothing, blemish-supporting properties, working alongside niacinamide to keep oilier, congestion-prone skin calmer.

  • Research: Topical zinc has recognised anti-inflammatory and oil-regulating effects useful for acne-prone skin.

๐ŸŒŠ Glycerin Humectant Proven

A gold-standard humectant that pulls water into the upper layers of skin, keeping the formula hydrating and comfortable despite its oil-free base.

  • Research: Glycerin is one of the most studied and effective moisturising humectants in all of skincare.

๐Ÿฅฅ Coco-Caprylate/Caprate Emollient Supporting

A lightweight, coconut-derived emollient that gives the serum a silky, fast-absorbing slip without a greasy film โ€” a clean stand-in for heavier facial oils.

โš ๏ธ
As an ester, it can feed Malassezia yeast โ€” worth noting if you're prone to fungal acne.

๐Ÿงด Caprylic/Capric Triglyceride Emollient Supporting

A light, coconut/palm-derived emollient that smooths application and helps spread the actives evenly across the skin while keeping the finish weightless.

โš ๏ธ
Another ester that isn't considered fungal-acne (Malassezia) safe.

๐Ÿฉน Pantolactone Conditioning Supporting

A precursor to panthenol that adds extra soothing and conditioning, helping skin feel calmer and more comfortable after blemishes.

  • Role: Works with panthenol to support hydration and a soft, supple skin feel.

๐Ÿ‹ Citric Acid pH adjuster Supporting

Included in a small amount to fine-tune the formula's pH so the actives stay stable and skin-friendly. It is not present at exfoliating (AHA) levels here.

  • Role: Buffering / pH balancing rather than active exfoliation.

SPF (AM)

Use morning and night. Apply after cleansing to slightly damp skin, before heavier creams. In the morning, always finish with SPF โ€” and if you also use a benzoyl peroxide treatment (e.g. Acnecide gel), apply that to active spots and reserve this serum for the marks they leave behind.

๐Ÿ“ How to Use

1

Cleanse

Wash with a gentle, soap-free cleanser and pat skin until it's just damp.

2

Apply

Dispense 1โ€“2 pumps and smooth over the whole face, or apply directly onto post-breakout marks.

3

Layer

Follow with a suitable day or night moisturizer. Use both morning and night for best results.

4

Protect

In the morning, finish with a broad-spectrum SPF 30+ to protect fading marks from darkening.

๐Ÿ‘ค Who Is It For?

โœ… Perfect for you if:

  • You have post-acne marks, redness or uneven texture you want to fade
  • You want retinol-like benefits without the irritation or peeling
  • You have oily, combination or acne-prone skin
  • You prefer fragrance-free, oil-free, vegan formulas
  • You're easing into "actives" and want something gentle

โŒ Consider alternatives if:

  • You're prone to fungal acne / Malassezia folliculitis (the esters can trigger it)
  • You're pregnant or breastfeeding and want to avoid bakuchiol without a doctor's sign-off
  • You need a high-strength treatment for active cystic acne (this targets marks, not flares)
  • You want fully disclosed, percentage-labelled active concentrations
  • You have very dry skin and need a richer, more occlusive serum

โ“ Frequently Asked Questions

Its niacinamide and panthenol are widely considered pregnancy-safe, but the serum also contains bakuchiol โ€” a retinol-like active that hasn't been well studied during pregnancy. Because of that, most dermatologists suggest avoiding it, or getting your doctor's okay first, while pregnant or breastfeeding.

No. It contains coco-caprylate/caprate and caprylic/capric triglyceride (esters) plus lysolecithin, which can feed Malassezia yeast. If you're prone to fungal acne, choose an ester-free niacinamide serum instead.

Generally, yes. Bakuchiol is gentle and can even be layered with retinol or vitamin C. With strong AHAs/BHAs, introduce it slowly and on alternate days at first to avoid over-exfoliation. Niacinamide pairs well with almost everything.

It's ideal for oily, combination and acne-prone skin thanks to its oil-free, non-comedogenic formula. Dry and sensitive skin can use it too โ€” just layer a richer moisturizer on top and patch test first.

Brand testing reports smoother, brighter skin within about a week, with redness and dark marks looking less noticeable around 4 weeks. Realistically, fading post-acne marks is gradual โ€” expect the best results after roughly 8โ€“12 weeks of consistent twice-daily use.

After cleansing (and toner, if you use one) and before moisturizer. Apply it to the whole face or directly to marks, morning and night. In the morning, always finish with SPF.

It's formulated to be oil-free and non-comedogenic, so it's very unlikely to clog pores (we'd rate it around 1/5). The one caveat is fungal acne โ€” the esters aren't Malassezia-safe even though they sit low on the comedogenic scale.

Around 12 months after opening (look for the 12M symbol on the packaging). Stored in a cool, dry place with the cap closed, the 30 ml pump typically lasts about 2โ€“3 months with twice-daily use.

โ˜…โ˜…โ˜…โ˜…โ˜†
4.3 out of 5

Verdict: A smart, affordable mark-fader that punches above its drugstore price. The bakuchiol-plus-niacinamide combo delivers retinol-like smoothing and real brightening without the irritation, in a lightweight oil-free base that acne-prone skin loves. It won't tackle active cystic acne, it isn't fungal-acne safe, and the brand keeps its exact percentages under wraps. But for gently fading post-breakout marks and evening out texture โ€” especially layered with the rest of the Acnecide/Purifide range โ€” it's an easy, low-risk recommendation. Just be patient and give it a full 8โ€“12 weeks.

lightbulb What are Notable Effects & Ingredients?

Ever used a product that promised a certain effect but provided no results? It might not have contained any notable ingredients that could have been responsible for that promised effect. It doesn't matter what the marketing or packaging ยซpromisesยป it can do, if it doesn't contain anything that can help - then the likelihood of it helping is low.

We help you identify key notable ingredients that have been shown to help with effects such as acne-fighting, brightening, UV-protection, wound healing & anti-aging to help you achieve your skincare goals smarter. Please note that different notable ingredients have varying levels of research behind them, some are extremely well proven yet some have mixed research in their efficacy.

muscle Pro Tip Alert!

Just because a product doesn't contain any notable ingredients doesn't mean it's bad. And a product with notable ingredients (or even many) doesn't necessarily guarantee the efficacy of the product performing these effects either. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine this.

question
lightbulb What is the Ingredient Safety Breakdown?

Ingredient Safety Breakdown refers to the percentage % of ingredients in different risk categories as classified by EWG (Environment Working Group) if they are available. There are almost endless cosmetic ingredients and they are one of the few organisations globally that have assigned ratings to a lot of the more commonly used ingredients which is why we reference them.

muscle Pro Tip Alert!

EWG is seen by many to be more on the alarmist side in their assignment of health ratings resulting in rating ingredients as riskier than they actually are. We recommend using this a reference point rather than a strict guide of ingredient safety and to always do further research if into ingredients that you may find suspect.
