Dr. Squatch soap is not a good choice for eczema-prone skin. While the brand uses natural ingredients and avoids synthetic detergents, several core features of its products, including high pH, essential oil fragrances, and physical exfoliants like sand, work against what eczema skin actually needs. Some individual ingredients like pine tar and oatmeal have real skin-soothing properties, but the overall formulation creates more risk than benefit for people managing eczema.
Why the pH Is a Problem
Dr. Squatch bars are cold process soaps, which typically have a pH between 8.5 and 10. Healthy skin sits around 4.5 to 5.5, a slightly acidic environment known as the acid mantle. This acid mantle is already compromised in people with eczema, and washing with a high-pH soap pushes it further out of balance.
When alkaline soap contacts the skin, it dissolves some of the protective lipids that sit between skin cells. These lipids normally form a tight barrier that keeps moisture in and irritants out. Once disrupted, gaps form between cells, water escapes faster (a process called transepidermal water loss), and the skin dries out. Research shows that skin pH remains elevated for at least 30 minutes after washing with cold process soap, meaning the barrier stays vulnerable well after you rinse off. For eczema skin that’s already struggling to retain moisture, this repeated cycle of disruption can trigger or worsen flares.
Fragrance and Essential Oils
Dr. Squatch bars are built around bold scents. The Pine Tar bar contains orange essential oil and pine fragrance. Other varieties use cedarwood, peppermint, eucalyptus, and citrus oils across the product line. These aren’t synthetic fragrances, but that distinction doesn’t make them safer for eczema.
People with atopic dermatitis are specifically identified as a higher-risk group for allergic contact dermatitis from essential oils. Orange oil, cedarwood oil, peppermint oil, eucalyptus oil, and lemon oil all appear on the list of essential oils commonly associated with skin reactions. A single exposure might not cause trouble, but daily use on already-inflamed skin increases the odds of sensitization over time. Once you develop a contact allergy to an essential oil, even trace amounts can trigger a reaction.
Dermatologists consistently recommend fragrance-free cleansers for eczema. As Dr. Michael Jacobs, an associate professor of dermatology at Weill Cornell Medical College, has noted, both synthetic fragrances and essential oils can aggravate sensitive skin, and fragrance-free products are the safest option.
Exfoliants Like Sand and Oatmeal
Most Dr. Squatch bars contain physical exfoliants. The Pine Tar bar includes sand, oatmeal, and activated charcoal. The Deep Sea Goat’s Milk bar is rated at “medium” grit and contains oatmeal and kaolin clay. Even bars marketed as gentler still have some texture.
Oatmeal on its own is genuinely soothing for eczema. It has anti-inflammatory properties and helps calm irritated skin. But in a soap bar, oatmeal functions partly as a scrubbing agent. Combined with sand or other abrasives, it creates friction that can micro-damage the skin barrier. The National Institute of Allergy and Infectious Diseases recommends that people with eczema use gentle cleansers and avoid scrubbing their skin. Exfoliating inflamed eczema skin can do more harm than good, especially when the scrubbing particles are embedded in every wash rather than used selectively.
The Pine Tar Question
Pine tar is the one ingredient in Dr. Squatch’s lineup with legitimate evidence behind it for eczema. A clinical trial on children with moderate-to-severe eczema found that pine tar baths improved disease severity. A broader review concluded that pine tar is an effective topical treatment with minimal safety risk, based on its long history of use for inflammatory skin conditions.
The catch is that pine tar in a Dr. Squatch bar sits alongside all the other problematic ingredients. You’re getting a small amount of pine tar extract mixed with high-pH soap, essential oils, and sand. The potential benefit of the pine tar doesn’t offset the cumulative irritation from everything else in the formula. If you’re interested in pine tar for eczema, a dedicated pine tar treatment product without fragrance and exfoliants would be a more targeted approach.
No Eczema Certification
Dr. Squatch does not carry the National Eczema Association’s Seal of Acceptance, which is a voluntary certification that evaluates whether products are suitable for eczema and sensitive skin. This doesn’t automatically disqualify a product, but it means the formulation hasn’t been reviewed against eczema-specific standards. Products that earn the seal are typically fragrance-free, pH-balanced, and free of common irritants.
What Works Better for Eczema
Dermatologists generally recommend syndet bars (synthetic detergent bars) over traditional soap for eczema. Syndets are formulated at a lower pH, closer to the skin’s natural range, and they clean without stripping the lipid barrier the way saponified oils do. Research confirms that syndet bars leave skin more hydrated and maintain the integrity of the outer skin layer significantly better than soap-based bars. They’re recommended as part of the daily routine for people with atopic dermatitis, rosacea, and other barrier-compromised conditions.
The ideal cleanser for eczema is fragrance-free, has a pH between 5 and 7, contains no physical exfoliants, and ideally includes a moisturizing agent like ceramides or glycerin. This is essentially the opposite profile of a Dr. Squatch bar. If you enjoy Dr. Squatch on the rest of your body and your skin tolerates it, limiting use to non-eczema areas while using a gentle, fragrance-free cleanser on affected skin is a reasonable compromise. But on active eczema patches, these bars are likely to make things worse.
