Ingredients Explained

These ingredients are found in both products.

Ingredients higher up in an ingredient list are typically present in a larger amount.

Hydrocolloid is not an INCI ingredient. It's a soft, gel-forming material that got its start in hospital wound care.

A typical hydrocolloid layer is coated with a mix of gelatin, pectin, xanthan gum, carrageenan, and Sodium Carboxymethylcellulose (the parts that soak up fluid) into a sticky rubber base, and then pressed into a thin film backing.

When you stick it on an open or "popped" pimple, these polymers pull in the fluid and turn it into a gel. This helps keep the spot moist and creates a barrier against outside bacteria. Plus, there's some UV blocking as well so the spot is less likely to leave a dark mark.

The current research is small but encouraging. A 2006 study found hydrocolloid dressings on acne lesions:

A 2024 manufacturer study in 41 subjects aged 12-35 showed patches significantly improved the appearance of popped pimples by Days 1 and 4, with improvements in smoothness, crusting, redness, size, and dryness.

Another 2025 trial on a related hydrogel patch reported a 35% reduction in lesion size and a 44% improvement in lesion severity by Day 2 versus the control group.

Just remember patches mostly help surface whiteheads; they generally cannot treat blackheads and do not help deeper cystic or persistent hormonal acne. There are a few case reports that link rosin-based tackifier in some dressings to contact dermatitis as well.

Because it is a patch, there's no meaningful "usage percentage".

The adhesive itself is usually 50-70% hydrocolloid powders with the rest as elastomer.

Ingredients Explained

  1. 01These ingredients are found in both products.
  2. 02Ingredients higher up in an ingredient list are typically present in a larger amount.
  3. 03Butylene Glycol (or BG) is used within cosmetic products for a few different reasons:
  4. 04Overall, Butylene Glycol is a safe and well-rounded ingredient that works well with other ingredients.
  5. 05Though this ingredient works well with most skin types, some people with sensitive skin may experience a reaction such as allergic rashes, closed comedones, or itchiness.
  6. 06Carbomer is a synthetic thickening and gelling agent. It's basically the ingredient that gives a lot of serums, gels, creams, and sunscreens their smooth, non-sticky texture.
  7. 07Although legally permitted at very high levels, carbomers are normally used at concentrations below 1%.
  8. 08It also needs to be neutralized to actually thicken, and because it is a large molecule, it doesn't really penetrate the skin barrier.
  9. 09Allergy-wise, the risk is very low. Clinical studies show carbomers have low potential for skin irritation/sensitization even at concentrations up to 100%.
  10. 10A 2024 UK study patch-tested 1,302 patients and found true allergy to the parent group of carbomer to be rare with no confirmed relevant reactions.
  11. 11Glycerin (or glycerol) is a compound naturally found in your skin. It's a powerhouse humectant that pulls water into the stratum corneum.
  12. 12Topically, glycerin does several things at once:
  13. 13Your skin makes glycerin on its own (mostly from sebaceous oil breakdown) and shuttles it to your outermost layer of skin, or your epidermis, via aquaporin-3.
  14. 14Aquaporin-3 is a transporter that is essential for normal skin hydration, elasticity, and repair. Interestingly, mice lacking in AQP3 have dry and less elastic skin that can be fully corrected with glycerin.
  15. 15This ingredient is non-irritating, plays well with almost every ingredient, and works across all skin types. Typical use is anywhere between 3-10% but can go up to 79% in some leave-on products.
  16. 16Just know very high concentrations (>40%) can feel tacky in low humidity.
  17. 17Glycerin is the name for this ingredient in American English. British English uses Glycerol/Glycerine.
  18. 18Phenoxyethanol is one of the most widely used preservatives in skincare (and for good reason!).
  19. 19It has a large spectrum of antimicrobial activity and especially effective bacteria, yeast, and mold while only having a weak effect on your skin's natural microbiome.
  20. 20On a cellular level, it disrupts the cell membranes of microbes by poking holes that make the cell leak. This shuts down the chemical reactions the microbe needs to make energy so it can no longer survive.
