Dermalogica Deep Acne Liquid Patch – 0.5 fl oz sulfur spot treatment with niacinamide, invisible breathable film for blemish-prone

Dermalogica Deep Acne Liquid Patch is an invisible, liquid-to-patch sulfur spot treatment that soothes active blemishes, helps reduce surface oil, and encourages clearer-looking skin.

This lightweight formula starts as a liquid and sets into an invisible, breathable patch that protects the blemish while delivering targeted ingredients. It combines 5% colloidal sulfur with niacinamide to address excess oil and uneven post-blemish tone, while camphor, polylysine, and pomegranate extract refresh and refine the skin’s appearance. The film it forms helps shield the area from pollution and external irritants, allowing the active actives to work discreetly throughout the day or night.

How does the liquid-to-patch technology work?

After application, the product dries down into a thin, transparent barrier that sticks to the skin and creates a localized environment over the blemish. The patch is breathable, so it allows airflow while keeping dirt and external contaminants out. This delivery method concentrates the actives at the spot without smearing or transferring to clothing.

• Applies as a liquid and forms an invisible protective film
• Breathable barrier reduces transfer and contamination
• Concentrates ingredients directly on the blemish area

What active ingredients help reduce breakouts and post-blemish discoloration?

The formula contains 5% colloidal sulfur, which helps manage surface oil and the look of blemishes, while niacinamide (vitamin B3) supports overall skin balance and can improve the appearance of uneven tone after breakouts. Pomegranate extract works to refine skin texture, and camphor with polylysine provides a soothing, cooling sensation.

• 5% colloidal sulfur targets surface oil and blemish appearance
• Niacinamide helps balance skin and reduce post-blemish tone
• Camphor and polylysine deliver a calming, refreshing feeling
• Pomegranate extract smooths and refines texture

How should I use it and when will I see results?

Apply a small amount directly to clean, dry blemishes and let the product set into a thin film. Use it as part of your daytime or nighttime routine; the invisible patch allows makeup or sunscreen over top if needed. Visible changes in redness and surface oiliness can occur quickly, while improvements in discoloration and texture may take consistent use over several weeks.

• Use on clean, dry skin; apply sparingly to the blemish
• Allow to dry into an invisible patch before touching or layering products
• Can be worn day or night; results vary by skin type and frequency

Will this upset sensitive skin or conflict with other actives?

The formula is designed to be targeted and low-residue, minimizing broad irritation when applied only to blemishes. Because it contains sulfur and camphor, those with very reactive skin should patch-test first and avoid combining with other strong spot actives unless advised by a professional. It’s generally compatible with established skincare routines when used spot-only.

• Targeted application lowers risk of widespread irritation
• Patch-test if you have reactive or very sensitive skin
• Avoid layering multiple strong spot treatments on the same area

Who is this for: Dermalogica Deep Acne Liquid Patch is suited for people with blemish-prone skin who want a discreet, targeted option to manage surface oil and the appearance of spots without visible patches or heavy creams. It’s ideal for anyone seeking a focused treatment that can be worn under makeup or during the day, and for those wanting ingredients that address both immediate blemish appearance and follow-up tone and texture.
