Dark marks left after breakouts

The pimple itself is gone. What stays is a flat brown, red or purple spot where it used to be. These marks can sit on your skin for weeks or even months.

This is your skin's answer to swelling. Deep, sore spots push your skin to make extra color, called pigment, while they heal. Deeper skin tones often hold that color longer.

Picking or squeezing a spot can make the mark darker. Sun does the same. Flat marks are not scars, since a scar is a dent or a raised bump you can feel with a finger.

When to see someone

See a doctor or a skin doctor (dermatologist) if the marks are dents, pits or raised ridges. Go as well if deep, painful lumps keep coming back, or if a spot bleeds, crusts or grows. Dark patches that show up after you start a new drug also need a check.

Below is a list of home and folk remedies linked to cystic acne. We do not say any of them will fade your marks. Each one carries a grade that shows how much research stands behind it, so read the grades before you try anything.

10 options · 1 graded A · 1 graded B · 2 graded C · 6 traditional or ungraded

What does my cystic acne mainly look and feel like?

Deep, swollen, painful lumps under the skin — calming the inflammation matters most to me

  1. Tanshinone

    Supported by controlled trials (Evidence grade A · No traditional record)

    Clinically reviewed for acne vulgaris

    Why this matches
    Tanshinone's studied benefits center on reducing the severity of inflamed acne lesions, making it most relevant for deep, cystic breakouts.
    Why try it
    Supported by a systematic review and meta-analysis, tanshinone (from the herb Salvia miltiorrhiza) has been shown to have efficacy and a reasonable safety profile for acne vulgaris.
    Dose or use
    Follow product labeling; consult a healthcare practitioner.
    Time to results
    Typically 4–8 weeks
    Key study
    Systematic review (2025, PMID 40230697): Efficacy and safety of Tanshinone capsule in Acne vulgaris: a systematic review and meta-analysis.
    Caution
    Consult a healthcare practitioner before use, especially if taking other medications.

  2. Glutathione

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)

    Antioxidant; evidence is in milder acne

    Why this matches
    For deep, inflamed cysts, glutathione's antioxidant and anti-inflammatory activity may offer general support — though its strongest evidence is in milder acne, not severe cystic disease.
    Why try it
    In a randomized controlled trial, oral glutathione lowered inflammatory markers and improved acne severity in people with mild-to-moderate acne. It may complement, rather than resolve, deep cystic breakouts.
    Dose or use
    Follow product labeling; consult a healthcare practitioner.
    Time to results
    Typically 4–8 weeks
    Key study
    RCT (2025, PMID 41014073): oral glutathione reduced nitric oxide and IL-1a and improved clinical severity in mild-to-moderate acne vulgaris — not studied specifically in severe cystic acne.
    Caution
    Consult a healthcare practitioner if pregnant, breastfeeding, or on medications.

  3. Niacinamide (Nicotinamide)

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Vitamin B3 that may calm inflamed skin

    Why this matches
    For deep, inflamed lesions, niacinamide (vitamin B3) is valued for reducing redness and excess oil without irritation.
    Why try it
    Niacinamide is widely used topically to reduce inflammation and sebum in acne-prone skin. It's well tolerated and pairs easily with other steps in a routine.
    Dose or use
    Apply a 4–5% niacinamide serum or lotion to affected areas once or twice daily.
    Time to results
    Typically 8–12 weeks
    Key study
    Vitamin B3 is commonly used topically to reduce inflammation and oil in acne; presented here without a specific clinical citation, so it is ungraded.
    Caution
    Generally well tolerated; introduce slowly and patch test first if your skin is reactive.

  4. LI11 (Quchi) - Large Intestine 11

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Acupressure point for inflammation & skin

    Why this matches
    Since inflammation is your biggest struggle, LI11 is the acupressure point most associated with calming inflammatory skin conditions.
    Why try it
    On the Large Intestine meridian, LI11 (Quchi) is traditionally used for its anti-inflammatory action and for inflammatory skin conditions like eczema and psoriasis. It's a gentle, no-cost complement to other approaches.
    Dose or use
    Apply firm circular pressure to the point at the outer end of the elbow crease for 1–2 minutes, a few times daily.
    Time to results
    Varies; use consistently alongside other measures
    Key study
    Traditionally used in Chinese medicine for inflammation and inflammatory skin conditions; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Avoid strong pressure if pregnant; acupressure supports but does not replace treatment for cystic acne.

Alongside the cysts, my skin stays oily and breakout-prone — clogged pores and surface bacteria are a constant battle

  1. Tea Tree Oil

    Supported by smaller clinical studies· Recognised traditional use (Evidence grade B · Traditional use recognised)Recognised traditional use

    Topical antimicrobial with clinical acne evidence

    Why this matches
    If you'd rather apply something topical, tea tree oil is a well-established natural spot treatment for acne-prone skin.
    Why try it
    Topical tea tree (melaleuca) oil has been studied as a natural spot treatment for acne, with terpinen-4-ol acting against acne-related bacteria and helping calm inflammation. A recent systematic review and meta-analysis found it can help reduce lesions in mild-to-moderate acne. Evidence in severe cystic acne specifically is still limited, so treat it as a gentler-smelling complement rather than a replacement for cyst-focused care.
    Dose or use
    Dilute to about 5% in a carrier oil and dab on affected areas; patch test first.
    Time to results
    Typically 4–12 weeks
    Key study
    Systematic review and meta-analysis (2026, PMID 42098589): Efficacy and Safety of Melaleuca alternifolia (Tea Tree) Oil for Acne — pooled seven clinical studies and found topical tea tree oil can reduce acne lesions, while noting the evidence base remains limited and inconsistent and was studied mainly in mild-to-moderate acne rather than severe cystic disease.
    Caution
    Can irritate or dry sensitive skin; never apply undiluted, and do not ingest.

  2. Niacinamide (Nicotinamide)

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Vitamin B3 that may calm inflamed skin

    Why this matches

    Key study
    Vitamin B3 is commonly used topically to reduce inflammation and oil in acne; presented here without a specific clinical citation, so it is ungraded.
    Caution
    Generally well tolerated; introduce slowly and patch test first if your skin is reactive.

  3. Neem Oil

    Not yet assessed· We have not reviewed the literature for this one (Evidence grade not assigned · Traditional use recognised)Recognised traditional use

    Traditional topical antimicrobial for skin

    Why this matches
    Neem oil is a practical topical option for those who prefer traditional remedies applied directly to problem areas.
    Why try it
    Traditionally used in Ayurvedic practice for its antimicrobial and anti-inflammatory properties, neem oil is commonly applied topically to support clearer skin.
    Dose or use
    Apply a small amount to affected areas; dilute with a carrier oil if skin sensitivity is a concern.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    Avoid near eyes; do not ingest; patch test first as it may irritate sensitive skin.

My breakouts flare with certain foods, stress, or gut issues — I suspect something internal is driving them

  1. Probiotics (Lactobacillus plantarum P8)

    Limited human trials so far· Most of the research is laboratory or animal work (Evidence grade C · No traditional record)

    Gut-skin axis support for acne

    Why this matches
    If your breakouts feel tied to diet, stress, or digestion, supporting the gut-skin axis is a sensible place to start.
    Why try it
    A systematic review supports probiotics as a category for acne through the gut-skin axis. The evidence is at the class level — this specific strain has not been shown in its own acne trial.
    Dose or use
    Follow product labeling; consult a healthcare practitioner.
    Time to results
    Typically 4–8 weeks
    Key study
    Systematic review (2026, PMID 41703218): Prebiotics, Probiotics, and Postbiotics for Acne Vulgaris — supports probiotics as a category via the gut-skin axis, not this specific strain.
    Caution
    Generally well tolerated; those who are immunocompromised should consult a doctor first.

  2. Zinc Deficiency

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Low zinc is linked to inflammatory acne

    Why this matches
    Since your breakouts feel tied to diet and gut health, a zinc shortfall is worth ruling out — low zinc is commonly associated with inflammatory acne.
    Why try it
    Zinc supports skin repair and immune balance, and the library flags skin issues like acne as an early sign of low zinc. Correcting a confirmed shortfall addresses a possible root cause rather than masking symptoms.
    Dose or use
    Consider testing zinc status; if low, correct through diet or supplementation under a clinician's guidance.
    Time to results
    Typically 8–12 weeks
    Key study
    Low zinc is repeatedly associated with acne severity; correcting a confirmed deficiency is a recognized supportive step, not a standalone treatment.
    Caution
    High-dose zinc can deplete copper and upset the stomach; don't exceed recommended intake without testing.

  3. Omega-3 fatty acids

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Anti-inflammatory fats for dietary support

    Why this matches
    If diet and systemic inflammation are part of your acne picture, omega-3s are a reasonable anti-inflammatory addition to your routine.
    Why try it
    Omega-3 fatty acids are widely used for their anti-inflammatory effects. A direct benefit on acne lesion severity has not been confirmed in controlled trials measuring breakouts.
    Dose or use
    1,000–2,000 mg EPA/DHA daily with food
    Time to results
    Typically 6–12 weeks
    Key study
    Used for general anti-inflammatory dietary support; a direct effect on acne lesion or severity has not been confirmed in controlled clinical trials.
    Caution
    May thin blood at high doses; check with a doctor if on blood thinners.

  4. Curcumin

    Centuries of traditional use· Human evidence not yet assessed (Evidence grade not assigned · Traditional use long-standing)Long-standing traditional staple

    Traditional anti-inflammatory botanical

    Why this matches
    Curcumin fits well for those seeking a gentler, traditionally used option to complement an existing routine.
    Why try it
    Traditionally used in Ayurvedic and herbal practice for its anti-inflammatory and antimicrobial properties, curcumin is commonly applied to inflammatory skin concerns.
    Dose or use
    Follow product labeling; consult a healthcare practitioner.
    Time to results
    Typically 4–8 weeks
    Key study
    Traditionally used for this condition; this specific use has not been confirmed in controlled clinical trials.
    Caution
    May interact with blood thinners; use cautiously before surgery.

What kind of help would I actually stick with?

I'm open to taking supplements or studied herbs internally to fight breakouts from within

This app is so cool! I've always wanted there to be a hub for all NATURAL remedies and preventative options but l've always had to do loads of digging to find the info I wanted for different natural products. HealisticMD has all the info I need in one place. It gave me various natural supplemental options for a condition I looked up, including what each remedy does and how much is usually recommended to take. It also gave me exact products I could buy for the problem I had looked up. It makes my process SO MUCH easier when I need to find non-pharmaceutical solutions to my needs.

There is a wealth of information on the app! I recently had bloodwork done and found I was deficient in a handful of vitamins and minerals (Vitamin B12, Vitamin D, Iron, etc.) HealisticMD made it simple for me to find out what foods to eat/ supplements I needed to improve these deficiencies. It gives you so many ideas on prevention, natural health tips, where to buy the vitamins, when to take them, why, etc. I love how easy the app is to use too. I am currently working on getting pregnant. I was pleasantly surprised to find compelling data along with supplement suggestions to aid in the process, some of which my fertility doctor wasn’t even aware of. Highly recommend downloading, after all health is one our greatest gifts!
