Hydro-Star + Salicylic Acid Pimple Patches
Hydro-Star + Salicylic Acid Pimple Patches
Product Description
By Starface β the original star-shaped pimple patch. Hydro-Star + Salicylic Acid are pale-blue hydrocolloid stars supercharged with 1% salicylic acid (BHA) to unclog pores, soak up fluid, and visibly flatten juicy, congested spots overnight while gently reminding you to stop picking. Vegan, cruelty-free, fragrance-free, and dermatologist-tested for every skin type, including sensitive.
β¨ Texture & Feel
Signature Star Shape
The little arms grip tricky contours β the side of your nose, the corner of your lip β and the redesigned formula is now 2x stickier so stars stay put without lifting.
Fluid-Absorbing Hydrocolloid
A clinically proven absorbent material that draws out gunk, sebum, and fluid from a juicy spot, visibly flattening it and calming redness while you sleep.
1% Salicylic Acid Boost
A beta hydroxy acid (BHA) that cuts through oil and dissolves dead skin cells, making these stars stronger on clogged pores than plain hydrocolloid patches.
Picking Protection
The star shields your breakout from outside bacteria and acts as a physical, visual reminder to keep your fingers off β so spots heal instead of scarring.
π‘οΈ Safety & Compatibility
Contains 1% salicylic acid. Topical BHA on a small spot is considered low-risk, but most guidance advises caution β check with your doctor or midwife first.
No esters, fatty acids, polysorbates, or ferments. The inert adhesive base and salicylic acid won't feed malassezia.
Fragrance-free, unscented, and dermatologist tested. Brand recommends a max of 1β3x per week so salicylic acid doesn't over-dry.
Apply to bare, dry skin. Avoid stacking other strong actives (retinol, AHA, benzoyl peroxide) directly under the patch to prevent irritation.
No animal-derived ingredients and never tested on animals. Suitable for vegan routines.
Broken or damaged skin. Stop use if rash or irritation occurs. For external use only; keep out of reach of children.
π¬ Ingredient Breakdown
π§ Hydrocolloid Patch base Proven
The absorbent gel-forming matrix (built on cellulose gum and adhesive polymers) is the heart of every Hydro-Star. It creates a moist, sealed environment that pulls fluid, pus, and debris out of a spot while shielding it from bacteria and your fingers.
- Mechanism: Forms a gel on contact with wound fluid, drawing exudate away from the blemish and keeping the area occluded for faster, cleaner healing.
- Brand clinical data: Starface reports its 100% hydrocolloid Hydro-Stars showed a visible difference in 6 hours for 87% of users in a 23-subject, 5-day study.
- Best for: Juicy, surface-level whiteheads and popped spots that are actively leaking fluid.
π§ͺ Salicylic Acid 1% Proven
A beta hydroxy acid (BHA) and the active ingredient that sets these stars apart from the classic version. It's oil-soluble, so it can penetrate into the pore lining to dissolve dead skin cells, sebum, and the gunk that causes clogged pores and persistent bumps.
- Function: Keratolytic exfoliant β loosens and clears the buildup inside congested pores while the hydrocolloid absorbs surface fluid.
- Concentration: A gentle 1% dose, delivered locally to the spot rather than across the whole face, which keeps irritation low.
- Evidence: Salicylic acid is a long-established over-the-counter acne ingredient widely studied for unclogging pores and reducing comedones.
8 ingredients
Cellulose Gum, Polyisobutene, Petroleum Resins, Styrene/Butadiene Copolymer, Paraffinum Liquidum, Polyurethane, Salicylic Acid, Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate.
π Where It Fits in Your Routine
Apply to completely clean, dry skin β before serum and moisturizer. Keep other products and actives off the spot underneath the star so it can grip and work. Best used at night.
π How to Use
Cleanse & dry
Wash your face and make sure the spot is completely clean and dry β no leftover serum or oil, or the star won't stick.
Peel & place
Tear the perforated backing, lift a star, and press it firmly over the blemish. Smooth down the little arms.
Leave it on
Wear overnight or for at least 6 hours. The patch turns opaque/white as it absorbs fluid β that's it working.
Remove & discard
Gently peel off and throw it away. Each star is single-use. Follow with moisturizer if needed.
Limit your use
Because of the salicylic acid, use these a maximum of 1β3x per week. Reach for plain hydrocolloid stars in between.
π€ Who Is It For?
β Perfect for you if:
- You get whiteheads or clogged, congested spots that need more than plain hydrocolloid
- You have oily or acne-prone skin
- You're a chronic picker and need a physical barrier
- You want a discreet, fragrance-free overnight spot treatment
- You like a fun, cute way to treat breakouts
β Consider alternatives if:
- Your breakout is deep, cystic, or a blind pimple under the skin (no fluid to absorb)
- The skin is broken, open, or already very dry/irritated
- You're pregnant or breastfeeding and avoiding salicylic acid
- You need a patch you can use every single day
- You want a truly invisible patch (these are pale blue)
π― Skin Type Compatibility
Salicylic acid cuts through excess oil while the hydrocolloid absorbs sebum β an ideal match for oily, congested skin.
Targets spots only where you place them, so oily zones get treated without drying the rest of the face.
Non-comedogenic and fungal-acne safe, with BHA for clogged pores. Made for breakout-prone skin.
Fragrance-free and dermatologist tested, but the salicylic acid means you should limit use and patch test first.
Effective on spots, but BHA can be drying β stick to 1β3x weekly and keep the surrounding skin moisturized.
π Results Timeline
Visible flattening begins
The hydrocolloid soaks up fluid and the spot starts to look flatter and less angry. The patch turns white where it's absorbing.

βοΈ Pros & Cons
β Praised
- Genuinely flattens juicy whiteheads overnight
- Salicylic acid tackles clogged pores better than plain patches
- Now 2x stickier β stays put through sleep
- Cute star shape that grips awkward spots
- Stops you picking and protects from scarring
- Vegan, fragrance-free, sensitive-skin friendly
β Criticized
- Useless on deep, cystic, or blind pimples
- Limited to 1β3x per week (the BHA can dry skin)
- Pricier per patch than basic hydrocolloid brands
- Pale-blue star is visible, not invisible
- Some report less stickiness vs the classic version
- Smaller count per pack than budget bulk options
π° Budget-Friendly Alternatives (Dupes)
The K-beauty cult favorite. Pure hydrocolloid in 3 sizes that absorbs fluid just as well β but no salicylic acid and no fun star shape, so weaker on clogged pores.
The best-selling hydrocolloid patch in the US. Invisible round dots that flatten surface spots, but it's 100% hydrocolloid with no BHA boost for congestion.
Hydrocolloid patches with tea tree and calendula oil instead of salicylic acid. Great value bulk count, but the botanical oils make it less fungal-acne friendly.

β Frequently Asked Questions
Use with caution. These contain 1% salicylic acid (a BHA). Topical salicylic acid applied to a small spot in low concentration is generally considered low-risk, but standard advice is to be cautious during pregnancy and breastfeeding. If you're pregnant or nursing, check with your doctor first β or simply switch to Starface's plain 100% hydrocolloid Hydro-Stars, which contain no active acids.
Yes. The ingredient list contains no fatty acids, esters, polysorbates, oils that feed yeast, or ferments β the things that typically trigger malassezia (fungal acne). The adhesive base is inert and salicylic acid is actually helpful, so these are considered fungal-acne safe.
Apply the patch to bare, dry skin and avoid layering other strong actives directly underneath it β occluding retinol, vitamin C, or extra acids under the star can cause irritation. You can absolutely use those products elsewhere on your face, just keep the area under the patch clean. Since the patch itself contains BHA, you don't need additional exfoliating actives on that spot.
They're excellent for oily, combination, and acne-prone skin thanks to the oil-cutting salicylic acid and fluid-absorbing hydrocolloid. They're rated good (rather than excellent) for sensitive and dry skin β still usable, but limit frequency and patch test first since the BHA can be drying.
Often within the first 6 hours you'll see a juicy spot start to flatten as the hydrocolloid absorbs fluid (Starface reports 87% of users saw a difference in 6 hours with its hydrocolloid formula). After a full overnight wear, most whiteheads look smaller and less red. For clearing congested pores, expect gradual improvement over 2β4 weeks of 1β3x weekly use.
After cleansing (and toning), on completely clean, dry skin β before serum and moisturizer. Place the star directly on the spot, then apply the rest of your routine around it. They work best overnight. Don't put creams or oils under the patch or it won't stick.
No. We rate them 1/5 on the comedogenic scale. Hydrocolloid is non-comedogenic and actually pulls debris out of pores, and the salicylic acid helps keep pores clear. They're dermatologist tested and designed specifically for acne-prone, breakout-prone skin.
About 24 months. Because each star is sealed in a foil sheet and the product has no water phase, it stays stable for a long time. Keep the sheets in a cool, dry place and the adhesive will stay sticky right up until you use them.
Verdict: Starface Hydro-Star + Salicylic Acid takes the brand's cult star patch and gives it a clogged-pore upgrade with 1% BHA. For juicy whiteheads and congested surface spots, these stars genuinely flatten and de-gunk overnight while looking cute and stopping you from picking. They're vegan, fragrance-free, fungal-acne safe, and sensitive-skin friendly. Just know the limits: they do nothing for deep cystic pimples, the salicylic acid caps use at 1β3x per week, and they cost a little more per patch than plain hydrocolloid brands. If you want a fun, effective spot treatment for clogged breakouts, they earn their place β keep a pack of plain hydrocolloid stars on hand for everything else.

Understanding Silicones
If you've ever used a skincare, makeup or beauty product that's made your skin look and feel smoother tempoarily - it's likely contained Silicone. They are a popular class of ingredients found in cosmetics due to their smooth, soft, easy-to-spread and smooth properties that help creates an artificial layer/barrier on top of skin or hair (commonly found in conditioners).
For the same reasons they are popularly used, they are also commonly avoided. Anecdotally, many individuals have reported that Silicones cause/excerbate breakouts, irritation, cause a feeling of skin being unable to breathe, cause clumping of cosmetic products and find it difficult to wash off. As a result, those who find them problematic are avoiding them and increasingly, cosmetic companies are avoiding them as well.
If you have had bad experiences with Silicones in the past, or suspect they are problematic then look out for the tick on the Silicone-free label.
Disclaimer
The Silicone-free label only includes the most common Silicone ingredients that have indentified been reported by individuals that could potentially cause issues.
These include: Amodimethicone, Behenoxy Dimethicone, Bis-Aminopropyl Dimethicone, Cetearyl Methicone, Cetyl Dimethicone, Cyclomethicone, Cyclopentasiloxane, Dimethicone, Dimethicone Copolyol, Dimethiconol, Methicone, Phenyl Trimethicone, Phenyl Trimethicone, Stearoxy Dimethicone, Stearyl Dimethicone, Trimethylsilylamodimethicone.
Note, that this does not include all ingredients part of the Silicone class of ingredients.
EU Allergen-Free
EU Allergen-Free
Understanding the Identified Contact Allergens
The EU's Scientific Committee on Consumer Safety (SCCS) has identified and established 26 cosmetic ingredients that are likely contact allergens (potential to cause skin allergies) as demonstrated in clinical or epidemiological studies. The EU's SCCS have recommend cosmetic companies to disclose them on the labels if used and in cases where the concentration exceeds 0.001% in leave-on products and 0.01% in rinse-off products, then they must be labelled.
Look out for the tick on the EU-Allergen free label to know your cosmetic is free from any of the 26 identified cosmetic ingredients.
For more information regarding the EU's Scientific Committee on Consumer Safety, please visit their official website.
Disclaimer
The EU Allergen Free label is for the 26 ingredients identified by the EU SCCS and products will be only flagged if a suspected ingredient is on it's ingredient list. It is possible for cosmetics to contain one of the suspect ingredients without it appearing on the ingredient list due to it not reaching the concentration threshold to disclose it and cosmetic manufacturers choice to not disclose it.

Fungal Acne (Molassezia) Safe
Understanding Fungal Acne (Pityrosporum Folliculitis/Malassezia Folliculitis)
Pityrosporum Folliculitis/Malassezia folliculitis or simply known as Fungal Acne is a persistent acne-like condition that commonly responds poorly to traditional acne-treating methods. Unlike most cases of Acne where bacteria is the culprit, Fungi is the culprit of Fungal Acne (Hence the name!). There are certain classes & groups of ingredients that have been shown to promote and feed the growth of the Fungal Acne, Fungi such as fatty acids, oils, esters, polysorbates and fermented ingredients.
For more information regarding Fungal Acne, please visit Simple Skincare Science (f.c) - #3 of our Recommend Skincare Resources for an amazing comprehensive guide!
Please Read: How to use the Fungal Acne (Malassezia) Label
At SkinCarisma, we've done our best to identify as many ingredients as possible but note the fungal-free label may not be 100% accurate due to the complexconditions and combination of ingredients that malezzeria can thrive on.
Additionally, products that may contain ingredients that have shown to feed Malassezia may not neccessarily exacerbate the condition due to concentration of ingredient used in the product, this information is simply not available on the products.
As a result, please note this is only an experimental label that can be best used to possible identify problematic products you have used in the past. It is in no way a perfect identifier nor a predictor in whether or not it will exacerbate or cause fungal acne. It will continue to be worked on as more information and research comes to light.
If you find any ingredients you believe should be included, please email us at snails@skincarisma.com.
Disclaimer
Due to the lack of substantial research into this area it is very likely there are other ingredients and class/groups of ingredients that could feed Fungal Acne which have not been indentified.
The Fungal-Safe label does not constitute as medical advice. For your specific case, always consult your medical professiona such as dermatologist, physician, pharmacist, or health care provider - please read our medical disclaimer for more information.
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 Β«promisesΒ» 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.
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.
Be smart and use this as just a starting point for you to make more informed and smarter choices and compare it with reviews to see if the product is right for you

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.
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.
