Overview
The Dermabon 2% Coal Tar Soap Bar 3.2oz is a medicated treatment bar, not a spa indulgence — and that distinction matters before you buy. Coal tar has been used in dermatology for well over a century, recognized by the FDA as an effective OTC active ingredient for conditions like psoriasis and seborrheic dermatitis. At a 2% coal tar concentration, this sits at a clinically meaningful level within the OTC range. You get a single bar in the box, which makes it a considered purchase rather than a casual add-to-cart. If you're expecting lather, fragrance, and a luxurious shower experience, look elsewhere. This is a functional skin treatment first.
Features & Benefits
The headline here is the 2% coal tar concentration, which works by slowing down abnormal skin cell production — the underlying driver of the scaling and flaking associated with psoriasis. That mechanism is well-established, which lends real credibility to the formula. The unscented formulation is genuinely worth noting; most coal tar products carry a strong, medicinal odor, so a neutral-smelling bar is a practical advantage for daily use. The brand also claims moisturizing properties alongside cleansing, though this is worth testing personally since coal tar can be drying for some skin types. It markets itself as free from harsh chemicals and artificial additives, though that claim is the brand's own and not independently verified.
Best For
This coal tar bar is most useful for people dealing with chronic skin conditions who want to work a treatment step into their existing shower routine without adding extra products. It suits those managing psoriasis plaques on the body, or seborrheic dermatitis on the face and scalp, particularly if they've already tried shampoo-based coal tar treatments and want something in bar form. The unscented formula also makes it a sensible pick for anyone with fragrance sensitivities. That said, this medicated soap rewards consistency — don't expect visible changes after one or two uses. Anyone with severe or worsening symptoms should get a dermatologist's input before relying solely on OTC options.
User Feedback
Among buyers who've used the Dermabon bar consistently, the most common positive feedback centers on reduced itching and a noticeable decrease in flaking over time. The unscented formula earns steady praise from those with fragrance-sensitive skin who felt shut out of other medicated options. On the other side, a recurring complaint is the size — at 3.2oz, it can feel small given the price, especially for daily users who go through it quickly. Some people also reported initial skin dryness in the first week or two, which improved as their routine adjusted. Lather is described as modest rather than rich. Results clearly depend on skin type and condition severity, so expectations should be calibrated accordingly.
Pros
- The 2% coal tar concentration sits at a clinically recognized OTC level for managing psoriasis and seborrheic dermatitis.
- Unscented formula is a meaningful differentiator — most coal tar soaps carry a harsh medicinal odor that discourages daily use.
- Works across the body, scalp, and face, reducing the need for separate treatment products in your routine.
- Consistent long-term users report measurable reductions in itching and visible flaking within a few weeks.
- Bar format is travel-friendly and easier to store than bulky medicated washes or liquid coal tar solutions.
- Free from artificial additives and harsh chemicals per the brand, which appeals to those watching ingredient lists closely.
- Most sensitive-skin users report tolerating daily use without significant irritation once their skin adjusts to the formula.
- Solid sales ranking among bath soaps reflects sustained buyer interest and repeat purchasing since its 2022 launch.
Cons
- At 3.2oz, the bar depletes quickly with daily full-body use, making the real per-use cost higher than it first appears.
- Coal tar can noticeably dry out skin during the first week or two, particularly for those already prone to dryness.
- Lather is minimal and thin — buyers used to rich, foamy soaps will likely find the texture underwhelming.
- Moisturizing and clean-ingredient claims are self-reported by the brand and have not been verified by independent third-party testing.
- Results vary considerably based on skin type and condition severity, making outcomes genuinely unpredictable for new users.
- Sold as a single bar with no multi-pack option, which raises the commitment barrier given the price point.
- Coal tar requires patience — users who quit after a week or two are unlikely to experience any real benefit.
- Not a substitute for professional care; moderate to severe flare-ups typically need prescription-strength treatment beyond what this bar can offer.

Suitable for:
The Dermabon 2% Coal Tar Soap Bar 3.2oz is a practical choice for anyone managing chronic scalp or skin conditions — psoriasis, seborrheic dermatitis, or persistent dandruff — who wants to fold a treatment step directly into their existing shower routine. It works particularly well for people who have explored shampoo-based coal tar treatments but need something versatile enough to address affected areas on both the body and face without juggling multiple products. The unscented formula is a genuine advantage for those with fragrance sensitivities, since many medicated alternatives carry a strong chemical odor that makes daily use uncomfortable. If you prefer a consistent, low-maintenance approach to symptom management over applying multiple targeted spot treatments, a bar-format option like this simplifies the process meaningfully. It also suits buyers who understand that realistic OTC coal tar therapy is about steady, ongoing control — not rapid overnight transformation.
Not suitable for:
Anyone expecting fast, dramatic skin clearing will likely be disappointed by this medicated soap, since coal tar works gradually and requires weeks of consistent use before meaningful symptom reduction becomes visible. If your psoriasis or dermatitis is severe, widespread, or progressively worsening despite OTC attempts, a dermatologist's prescription-strength treatments are a far more appropriate path than any bar soap. The Dermabon 2% Coal Tar Soap Bar 3.2oz is also a poor fit for buyers who judge value primarily by bar size, since at 3.2oz it will not last long with daily full-body application, making the ongoing cost a real consideration. People with very dry or already-compromised skin barriers should proceed cautiously, as coal tar can initially increase dryness before the skin adapts. Finally, if you are shopping for a lather-rich, spa-like bathing experience, this bar is simply not built for that purpose.
