Painful, hard to eliminate, often very visible — and above all, incredibly frustrating: under-skin pimples, also known as cystic or blind pimples, are one of the most stubborn forms of acne. Treating them requires a specific approach, quite different from dealing with regular breakouts. Here’s everything you need to know about why they appear, how to treat them effectively, and most importantly, how to prevent them with the right routine.
Under-skin pimples: what exactly are they?
Under-skin pimples are inflammatory lesions that form deep beneath the skin’s surface. Unlike regular pimples, they have no visible tip — no white or yellow head — which makes them impossible to pop without causing further damage.
These blemishes typically result from inflammation around the hair follicle, triggered by:
- Excess sebum, often hormonal in origin;
- A build-up of dead skin cells and bacteria that deeply block the hair follicle;
- Intense internal inflammation, creating a red, painful cyst that may feel warm to the touch.
These blind pimples most commonly appear on the chin, jawline, or cheeks — areas typically associated with hormonal fluctuations.
Why do under-skin pimples appear?
Several factors contribute to their formation, including:
- Hormonal imbalances
- Hormonal fluctuations — from the menstrual cycle, pregnancy, menopause, or chronic stress — are the leading cause of under-skin pimples. Androgens in particular stimulate sebum production, increasing the risk of clogged pores.
- Chronic stress
- Stress can trigger inflammatory flare-ups by raising cortisol levels. This hormone directly promotes excess sebum production, fuelling the development of deep, painful pimples.
- Skincare routine mistakes
- Using products that are too rich, too harsh, or simply not suited to your skin type can disrupt your skin’s natural balance and worsen the formation of these internal blemishes.
- Lifestyle habits
- A diet high in refined sugars, dairy, or ultra-processed foods can aggravate internal inflammation, making under-skin pimples more likely to appear.
How to treat under-skin pimples effectively?
Because these pimples are deeply embedded in the skin, surface-level treatments are rarely enough. Here are the best practices for real results:
- Don’t pop or pick
- Avoid squeezing or pressing these pimples at all costs: doing so risks spreading the inflammation deeper and leaving permanent scarring or dark spots.
- Targeted spot treatments: micropoint patches
- Micropoint patches are one of the most effective solutions for treating under-skin pimples at the very first sign.
At My SOS Beauty, our SOS Micropoint Patches feature tiny, painless microneedles loaded with powerful active ingredients, including:
- Salicylic acid: deeply unclogs pores and reduces inflammation.
- Tea tree essential oil: a potent antibacterial that limits bacterial growth beneath the skin.
- Niacinamide: soothes redness, calms inflammation, and helps prevent post-blemish marks.
These patches deliver active ingredients directly beneath the skin’s surface, targeting the pimple at its source. They visibly reduce size and discomfort within just a few hours.
Pro tip: apply a SOS Micropoint Patch as soon as you feel an under-skin pimple forming, and leave it on for several hours or overnight for maximum effectiveness.
- Use targeted blemish-fighting skincare
- Incorporate products formulated with proven active ingredients into your daily routine to tackle deep-seated blemishes:
- Gentle cleansers with salicylic acid or zinc
- Niacinamide serums (reduce inflammation and regulate sebum production)
- Lightweight, non-comedogenic moisturisers
- Incorporate products formulated with proven active ingredients into your daily routine to tackle deep-seated blemishes:
- Gentle heat or cold to soothe inflammation
- Apply a warm (not hot) compress to the area for a few minutes each day to help soften the inflamed zone and speed up healing. Conversely, if the pimple is very painful and swollen, a cold compress can quickly ease the discomfort.
How to prevent under-skin pimples from forming?
Prevention is always the best strategy against these stubborn blemishes. Here are the keys to keeping them at bay:
- Regulate sebum production: build a blemish-fighting routine that balances the skin without stripping it.
- Regular gentle exfoliation: use mild acids (AHA/BHA) to prevent the build-up of dead skin cells deep within the pores.
- Limit aggravating factors: cut back on sugar, dairy, and ultra-processed foods.
- Manage stress: yoga, meditation, deep breathing — find what works for you to keep daily stress levels in check.
Reduce recurrence with a balanced diet
What you eat plays a significant role in managing under-skin pimples. Make room in your daily diet for:
- Anti-inflammatory foods (turmeric, ginger, oily fish).
- Natural fibre and prebiotics (leafy greens, fresh fruit) to support gut health and skin balance.
- Stay well hydrated: drinking enough water helps flush out toxins and reduces the internal build-up of impurities.
