Dermalogica Deep Acne Liquid Patch Sulfur Spot Treatment 0.5 fl oz — Invisible, Niacinamide-Infused

Dermalogica Deep Acne Liquid Patch is an invisible sulfur-based spot treatment that transforms from a liquid to a breathable patch to help soothe, protect and visibly reduce the appearance of blemishes.

This fast-acting formula blends colloidal sulfur with niacinamide and botanical extracts to target individual spots without obvious residue. Designed to form a thin, protective film, it shields irritated skin from external pollutants while allowing airflow. The result is a neat, low-profile treatment you can wear during the day or overnight to help manage occasional breakouts.

How does the liquid-to-patch technology work?

The product applies as a clear liquid that sets into a flexible, almost invisible patch on the skin. Once converted, the patch creates a barrier that limits contact with dirt and fingers while still permitting skin to breathe. This unique texture makes it discreet and practical for wear under makeup or on the go.

• Applies clear and dries into a thin, protective film
• Allows airflow while shielding from pollution and irritation
• Stays low-profile so it’s suitable for daytime use

What active ingredients help reduce blemishes?

The formula centers on 5% colloidal sulfur to help control surface oil and the look of blemishes, paired with niacinamide to support more even post-blemish tone. Camphor and polylysine add a refreshing, soothing sensation, while pomegranate extract helps refine skin texture. Together, these actives target multiple visible signs of breakouts without heavy or drying residue.

• 5% colloidal sulfur to address surface oil and blemish appearance
• Niacinamide (Vitamin B3) to support balanced skin tone
• Camphor and polylysine for refreshing, calming effects
• Pomegranate extract to help smooth and refine skin texture

How should I use it during my routine?

Apply a small amount directly onto the blemish after cleansing and drying the area. Let the liquid set into a patch—avoid touching until it dries—and you can layer makeup if needed. Use as a spot treatment whenever breakouts appear, and follow your usual cleansing and moisturizing steps around the treated spot.

• Cleanse and dry skin before application
• Apply a thin layer directly to the blemish and allow to dry
• Wear under makeup or overnight; remove with your regular cleanser

Will this irritate sensitive or acne-prone skin?

The formula is designed for blemish-prone skin and includes calming elements like polylysine and pomegranate extract. However, because it contains active ingredients such as sulfur and camphor, patch-testing is recommended for those with very reactive skin. If irritation occurs, discontinue use and consult a skincare professional.

• Formulated for blemish-prone skin with balancing niacinamide
• Contains camphor and sulfur—patch test first if you’re reactive
• Stop use if persistent irritation develops

Who is this for: Dermalogica Deep Acne Liquid Patch is intended for people dealing with occasional pimples and surface blemishes who want a discreet, breathable spot treatment. It suits those who prefer a clear, non-greasy application that can be worn day or night, and anyone looking to combine targeted sulfur action with skin-balancing niacinamide and supportive botanicals.
