What is encapsulated (time-released) Benzoyl Peroxide?

Encapsulated Benzoyl Peroxide uses a controlled-release delivery system that gradually releases BPO over time instead of all at once. This reduces the peak concentration on the skin at any given moment — delivering antibacterial and keratolytic efficacy comparable to 10% BPO while causing significantly less dryness, redness, and irritation.

Why does 5% BPO work as well as 10%?

Clinical research has established that 5% Benzoyl Peroxide displays excellent exfoliating and antibacterial properties at levels similar to 10% BPO, but with substantially less irritation. Higher concentrations do not proportionally increase efficacy but do increase skin dryness and sensitivity.

How often should I use this acne treatment?

Begin with 1–3 times per week to assess tolerance. Because excessive drying of the skin may occur, limit use to 1–3 times per week or as instructed by your skincare professional. Increase frequency gradually as your skin adapts.

Targeted Nighttime Acne Treatment

Encapsulated BPO Technology — Antibacterial Efficacy
Comparable to 10%, with Significantly Less Irritation.

Circadia Nighttime Control Acne Treatment Lotion is a professional-grade spot and zone treatment that harnesses the power of Encapsulated (Time-Released) Benzoyl Peroxide 5% — the active ingredient most clinically proven to reduce acne-causing bacteria — in a controlled-release delivery system that dramatically reduces irritation. Unlike conventional BPO formulations that release the full concentration immediately upon contact with the skin, encapsulation technology gradually delivers BPO over time, reducing peak concentration at any given moment while maintaining sustained antibacterial and keratolytic (exfoliating) action. Research has established that 5% encapsulated BPO achieves efficacy comparable to 10% conventional BPO — clearing breakouts, reducing C. acnes bacterial load, and decongesting follicles — while causing substantially less dryness, redness, and sensitivity. Allantoin is a clinically validated soothing agent that calms irritation and reduces sensitivity — an ideal complement to BPO's drying action. Vitamin E (Tocopheryl Acetate) provides antioxidant protection and helps maintain skin comfort during treatment. The lightweight lotion texture is designed for targeted application to affected areas rather than whole-face use, keeping irritation risk minimal and allowing the skin to build tolerance at its own pace.

Key Actives

Smarter Benzoyl Peroxide — The Science of Encapsulation

Active Ingredient

Encapsulated BPO 5%

Time-released Benzoyl Peroxide 5% — reduces acne-causing bacteria, provides keratolytic (exfoliating) action to clear congested follicles, and prevents future breakouts. Efficacy comparable to 10% conventional BPO with significantly less irritation due to controlled, sustained release.

Soothing Agent

Allantoin

A clinically validated skin-calming ingredient derived from comfrey. Reduces irritation and sensitivity associated with active acne treatments, soothes inflammation, and promotes skin comfort — making it an essential complement to BPO-based therapies.

Antioxidant Support

Vitamin E (Tocopheryl Acetate)

A fat-soluble antioxidant that protects cellular membranes from free radical damage. Provides moisturizing benefits and supports overall skin comfort and resilience during active acne treatment.

Benefits

What It Does

Clears Breakouts

Encapsulated BPO 5% delivers sustained antibacterial action against acne-causing bacteria and keratolytic exfoliation to clear active breakouts and prevent new ones from forming.

Decongests Follicles

The keratolytic action of BPO helps dissolve the compacted dead cell matter and sebum that clogs follicles — reducing blackheads, whiteheads, and congestion-related breakouts over time.

Soothes Inflammation

Allantoin and Vitamin E calm redness and irritation during treatment — making this suitable for acne-prone skin that has previously struggled with the dryness and sensitivity of conventional BPO formulas.

Directions

How to Use

Evening only. Begin 1–3 times per week and increase as tolerated.

1

Cleanse & Apply Serums

In the evening, cleanse thoroughly and apply any targeted serums first. Nighttime Control Acne Treatment is applied as the final step — after serums, before sleep.

2

Apply a Thin Layer to Affected Areas

Dispense a pea-sized amount onto fingertips and apply a thin layer to affected areas only. Avoid contact with eyes. Do not overapply — a thin layer is sufficient for effective action.

3

Start Slowly — Build Tolerance

Begin with 1–3 applications per week. Because excessive drying of the skin may occur, do not increase frequency beyond what the skin tolerates. Use white or old pillowcases — BPO can bleach fabrics.
