Retinyl Acetate is part of the retinoid family. It is made from retinol and acetic acid.
Though retinyl acetate is more stable than retinol, it is also less effective and less irritating. This is due to the conversion line all retinoids have to go through.
All retinoids must be converted to retinoic acid. The further away from this end result, the less effective the ingredient is.
Fun fact: Retinyl acetate is commonly used as a Vitamin C additive for foods.

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.
