Anti Bump Solution (formerly named Anti Cyst Treatment)

Anti Bump Solution (formerly named Anti Cyst Treatment) is a potent topical cystic acne serum to visibly reduce the appearance of acne, blemishes and painful bumps that form deep within the skin.

Anti Bump Solution (formerly named Anti Cyst Treatment) by Renée Rouleau is a powerful spot treatment formulated to provide a quick recovery for reducing visible inflammation of stubborn cystic acne bumps that develop deep within the skin and can linger for weeks—or even months. When used immediately on a newly formed cyst, most will find they get a 50% quicker recovery (if not faster) than when using nothing at all. This revolutionary product has 30+ years of proven results and has completely replaced the need for expensive cortisone injections for many of its users. If you struggle with large, painful blemishes and bumps, this safe and proven acne treatment is definitely for you. The result? Clearer skin with less visible bumps and cysts under the skin. 

For cyst and bump sufferers, we also highly recommend using Vitamin C&E Treatment daily under sunscreen and Post-Breakout Fading Gel as a spot treatment to fade the dark marks that stubborn cysts can leave behind for weeks or even months to reveal brighter, more even-toned skin. Rapid Response Detox Masque is very effective for preventing the appearance of all types breakouts, including cysts, pustules, papules, and monthly hormonal blemishes. It is included in our Rapid Response Detox Kit. If your breakouts are predominantly on the chin and jawline area, check out our Chin Breakout Treatment Kit. 

Note: Cysts should never be picked at since they develop and heal deep within the skin and are not meant to come out the surface. Avoid picking and instead apply Anti Bump Solution. It's a lot easier to conceal a closed bump with makeup than an oozing scab. Read 8 tips for preventing chin and jawline breakouts.

  • How to Use

    • To effectively use Anti Bump Solution to reduce the appearance of cystic acne and blemishes: apply one drop to clean skin as soon as cyst becomes visible. When used in the morning or evening, first perform your regular routine. Next, take a damp tissue or q-tip and wipe the affected area clean before applying. Anti Bump Solution should be applied as the last step. Use day or night until the bump is no longer visible. This treatment can be effective for older cysts that are still lingering under the skin.
    • To PREVENT the appearance of cysts: Anti Bump Solution can also be used 2-3 times a week (or even daily) as a preventative serum on areas prone to both cysts and regular surface blemishes.
