3M Nexcare Thin Acne Patch

3M Nexcare Thin Acne Patch is an ultra-thin hydrocolloid patch, supplied 30 individually cut patches to a pack. The patch is built from a hydrocolloid matrix on the skin-facing side with a thin, waterproof outer film and an adhesive border, and it is formulated without any medicated or pharmaceutical active ingredient — the hydrocolloid material itself is the only functional layer. It is sold over the counter as a general-sale item, without a prescription.

Within the low-profile hydrocolloid category, this variant is positioned as a thin format, sitting closer to the skin than a thicker, more heavily padded hydrocolloid dressing, which is intended to make it less noticeable under everyday clothing or make-up. Each patch is individually cut from the sheet for single use, and the pack of 30 is designed to allow a fresh patch to be applied without needing to cut or resize the sheet.

The hydrocolloid material is a matrix (typically based on substances such as carboxymethylcellulose) that absorbs surface moisture and exudate from the skin it is placed on, forming a gel as it takes up fluid. This is a physical, material-level property of hydrocolloid dressings generally, rather than an effect specific to any added medicine. The outer film layer is waterproof and creates an occlusive covering over the patch, which is permeable to some oxygen exchange while limiting the entry of external water, dirt, and bacteria for as long as the patch remains intact and adhered.

Clean and dry the skin fully before applying, then select a patch that comfortably covers the area with a small margin of surrounding skin. Peel the patch from its backing without touching the hydrocolloid surface, position it directly over the area, and press down gently from the centre outward without stretching the patch.

Leave the patch in place for the wear-time period indicated on the packaging, and replace it once it turns visibly opaque or whitish, or sooner if it lifts at the edges. To remove, lift one edge gently and peel back slowly, supporting the surrounding skin.

Not applicable — this is a medical device, not a medicine requiring dosing.

Use each patch before the expiry date printed on the packaging. An unopened, properly stored pack should remain usable up to that date, but patches from an opened sheet should be kept sealed and used within a reasonable time to avoid the hydrocolloid layer being affected by ambient moisture.

Store the pack in a cool, dry place away from direct sunlight and humidity, and reseal the packaging after opening. Keep out of the reach of children.

• Common: Mild redness or irritation at the adhesive edge of the patch, particularly on sensitive skin or with repeated use in the same spot.
• Common: Slight residue or tackiness left on the skin after the patch is removed.
• Serious: Signs of a true hydrocolloid or adhesive allergy, such as widespread rash, swelling, or blistering, should be assessed by a doctor or pharmacist, and use should be stopped if this occurs.

• Not for use in anyone with a known allergy or hypersensitivity to hydrocolloid dressings or acrylic adhesives.
• Not intended for open, actively bleeding, or already infected skin lesions without prior assessment by a doctor or pharmacist.
• Not suitable for use over broken skin that shows spreading redness, warmth, or discharge, which needs professional evaluation first.

• Not applicable — this is a topical hydrocolloid patch with no medicated ingredient and no systemic absorption expected from normal use.
• No interactions with oral or topical medicines are known or expected from ordinary use of this product.
• No food interactions apply to this product.

• Clean and fully dry the skin before applying so the patch adheres securely and stays in place.
• Choose a patch size that covers the area with a small margin of clear skin around the edge, rather than one that only just covers it.
• Wait until the patch edges have fully settled before applying make-up over or around it, rather than immediately after application.
• Replace the patch once it turns opaque or whitish rather than leaving it on beyond that point.
• Store the sheet away from steam and humidity, such as a bathroom cabinet with heavy shower exposure.
• When removing a patch, lift gently from one edge rather than pulling straight up, to reduce pulling on the skin underneath.

Precautions: Avoid applying this patch over skin that is broken in more than a superficial way, or that already shows signs of infection, without first checking with a pharmacist. Use in children should be supervised by an adult, and the patch should be checked periodically for lifting or excessive soiling. Discontinue use if irritation develops at the application site.

When to See a Doctor or Pharmacist: Speak to a doctor or pharmacist if the covered area becomes increasingly red, swollen, or painful, if pus or discharge develops, or if fever occurs, as these may need separate assessment. Also seek advice if a persistent skin reaction to the adhesive continues after the patch is removed.
