Where it fits in your routine
ROUTINEApply after cleansing on completely dry skin, before any serums or moisturizers. Best used overnight for 6+ hours.
How to use
HOW TO USEWash Your Face
Make sure skin is completely clean and fully dry before application. Any moisture or product residue will reduce adhesion.
Put a Star on It
Gently peel a Hydro-Star from the sheet and place it directly on your pimple. Press lightly to secure. The star arms help reach tricky spots.
Let It Work
Leave the patch on for at least 6 hours, ideally overnight. The hydrocolloid will gradually absorb fluid from the blemish.
Gently Remove
Peel off slowly from the edges. If the patch has turned white/cloudy, it has absorbed fluid. Replace with a fresh star if needed.

Frequently asked questions
FAQYes! Starface Hydro-Stars are safe during pregnancy and breastfeeding. The original yellow patches contain only 100% hydrocolloid with no retinoids, salicylic acid, or other ingredients restricted during pregnancy. The hydrocolloid works topically with minimal systemic absorption. However, avoid the Salicylic Acid version (Big Blue) during pregnancy. Always consult your doctor with specific concerns.
Yes, Starface Hydro-Stars are completely fungal acne safe. Pure hydrocolloid contains no fatty acids, oils, esters, or fermented ingredients that feed malassezia yeast. This makes it one of the safest spot treatments for those with pityrosporum folliculitis. The single-ingredient formula means zero risk of triggering fungal acne flares.
Yes, but apply the patch to clean, dry skin BEFORE any active treatments. The hydrocolloid creates a barrier, so any serums or actives applied underneath won't reach the pimple effectively. For best results: cleanse, apply patch, leave on overnight, remove in morning, then continue with your regular routine including actives. Don't apply actives directly over the patch.
Starface Hydro-Stars work excellently for all skin types: oily (absorbs excess sebum), dry (creates moist healing environment), combination, sensitive (single gentle ingredient), and acne-prone (non-comedogenic, fungal-safe). They're dermatologist tested and especially recommended for those with reactive skin who need minimal ingredient formulas.
Most users see visible improvement overnight (6-8 hours). The patch will turn white/cloudy as it absorbs fluid, and the pimple should appear flatter and less red upon removal. Surface-level whiteheads respond fastest. Deeper pimples may need 2-3 consecutive applications or may not respond as well - hydrocolloid patches work best on pimples that have "come to a head."
Apply Hydro-Stars immediately after cleansing, on completely clean and DRY skin. This should be before toners, essences, serums, or moisturizers - any product residue reduces adhesion. Best used overnight. In the morning, remove the patch, then continue with your regular AM routine. The patch needs direct skin contact to work effectively.
No, Starface Hydro-Stars have a comedogenic rating of 0/5 - they will not clog pores. Pure hydrocolloid is a non-pore-clogging material that actually draws impurities OUT of pores rather than pushing anything in. This makes it safe for acne-prone and congestion-prone skin. The patches are also fungal acne safe.
Starface Hydro-Stars have a shelf life of approximately 24 months (2 years) after opening when stored properly. Keep them in their resealable pouch or compact, in a cool, dry place away from direct sunlight and excessive heat. The hydrocolloid won't degrade quickly, but exposure to air and humidity over time may reduce adhesive effectiveness.
Verdict: Starface Hydro-Stars are the perfect choice if you want to make acne treatment fun and visible rather than shameful. The single-ingredient formula is exceptionally safe for pregnancy, breastfeeding, sensitive skin, and fungal acne sufferers. However, they prioritize aesthetics over maximum efficacy - competitors like Hero Mighty Patch and COSRX often outperform on deeper pimples. Best for surface-level whiteheads, picking prevention, and anyone who wants to wear their patches with confidence in public. The viral success is well-earned for changing acne culture, even if they're not the most powerful option available.
Product Overview
Quick product notes are a great way to check if a product is free from commonly avoided ingredients by skincare enthusiasts. These preferences come about for different reasons depending on the ingredient such as personal experiences, sensitivities, health preferences & etc.
Just because a product is not free from a common preference does not mean it's a bad product! You can make a personal decision whether or not you want to use a product that contains these ingredients or not - click the labels of the preference to read more about them.
Quick Product Notes
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 «promises» 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.
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
Notable Effects & Ingredients
Why are some products great for some people and horrible for others? Well everyone has different skin types and different reactions to the same ingredients.
We've identified a range of ingredients that are commonly regarded as potentially good or bad for those with Dry, Oily/Acne-Prone or Sensitive skin.
A product that contains good or bad ingredients for your skin type doesn't always flat out make the entire product good or bad for your skin. There are other factors such as ingredient quality, concentration and formulation that will ultimately determine your skins reaction.
One of the best ways to use this section is to troubleshoot products you've had bad experiences with in the past. Check if it contains any of the marked ingredients to point out suspect ingredients to avoid in the future!
Ingredients Related to Skin Types
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.
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.
