- Use as needed from day one. There is nothing to build up to.
- Cellulose GumThe hydrocolloid itself — it gels as it absorbs fluid from the blemish.
- Hydrogenated Poly(C6-20 Olefin)Gives the patch its flexibility so it moves with the skin.
- PolyisobuteneThe adhesive film that holds the patch in place and seals the spot.
- Styrene/Isoprene CopolymerA binder that keeps the patch intact while it is worn.
Cleanse and dry the area thoroughly — the patch will not stick to damp or oily skin. Apply directly onto the spot before the rest of your routine, choosing a patch wider than the blemish. Leave for 8 to 10 hours or overnight. When it turns white it is saturated: peel it off gently and replace with a fresh one if needed. Do not use on unbroken cystic spots, where there is nothing to draw out.
Cellulose Gum, Hydrogenated Poly(C6-20 Olefin), Polyisobutene, Styrene/Isoprene Copolymer
A plain hydrocolloid spot patch, and deliberately so — four ingredients, no salicylic acid, no tea tree. It draws fluid out of a whitehead, seals the spot from bacteria and, more usefully, stops you picking at it. The 12mm round patch is thin enough to disappear under makeup, and it turns opaque white when it has done its job.
Key Benefits:
- 100% hydrocolloid — absorbs fluid from a whitehead overnight
- Seals the spot against bacteria and stops picking, so it heals without a mark
- No actives at all: safe on sensitive skin and alongside any retinoid or acid
- Thin tapered edge sits flat and wears under makeup
- Turns white when saturated, so you know when to change it
Suitable for
- acne-prone
- sensitive
- teen
- rosacea-prone
- Fragrance-free

Questions
It is a plain hydrocolloid spot patch with no actives. It draws fluid out of a whitehead, seals the spot, and stops you picking at it. It is fragrance-free and sits happily alongside a retinoid or acid routine.
Cleanse and dry the area thoroughly — it won't stick to damp or oily skin. Apply directly onto the spot, choosing a patch wider than the blemish, and leave for 8 to 10 hours or overnight. When it turns white it's saturated: peel it off and replace if needed.
It works on spots that have come to a head. Don't use it on unbroken cystic spots, where there's nothing to draw out.
