Key takeaways

Traditional soaps and synthetic cleansers can contain harsh ingredients that disrupt your skin’s natural pH, leading to dryness, irritation, and acne.
Mild soap is a gentle, emollient cleanser that helps keep your skin moisturized without stripping natural oils. It may ease symptoms of eczema and psoriasis.
If mild soap still causes redness or discoloration, itching, peeling, or dryness, stop using it and talk with a doctor or dermatologist. Choose fragrance-free, alcohol-free, or hypoallergenic options.

Soap removes dirt and sweat from your body, leaving your skin feeling clean and refreshed. But your body might not agree with the types of soap you use.

Some traditional or normal soaps can be too harsh. These products will clean your skin but can leave it dry or irritated.

In this case, mild soap might be a better choice. This type of soap contains gentle ingredients that leave your skin not only refreshed, but also healthier.

What is mild soap?

Some people assume that all soaps are created equal, but there’s a difference between traditional soap and mild soap. This difference has everything to do with the ingredients in these products.

Many soaps sold in stores aren’t “true” soaps. True soap is a combination of natural fats and an alkali (lye). Lye is also known as sodium hydroxide, which is a chemical that comes from salt.

Today, however, many traditional or normal soaps don’t contain lye or natural fat. These soaps are actually synthetic detergents or cleansers.

They can contain fragrance, sodium lauryl sulfate, and other ingredients that are harsh to the skin. These soaps can throw off the pH balance (acidity level) of your skin, triggering further irritation.

The average pH level in traditional soap is 9 to 10. However, your skin’s normal pH level is only 4 to 5.

Soaps with a high pH disrupt the skin’s natural pH, making it less acidic. This can lead to acne, skin dryness, and other problems.

Mild soap, on the other hand, doesn’t affect the pH of skin.

Benefits of mild soap

Mild soap is great for people who have sensitive skin and need a gentle cleanser. These products are an emollient, which is a non-cosmetic moisturizer.

Mild soap softens and soothes skin because it doesn’t strip away its natural nutrients and oils. This can give the appearance of younger, healthier-looking skin, as well as reduce symptoms of skin conditions like psoriasis and eczema.

Uses for mild soap

Mild soap may help improve the following conditions:

Acne

Acne includes blackheads, whiteheads, and other bumps that form when dirt and dead skin clog pores.

Acne is treatable with over-the-counter and prescription medications. Additionally, some people see an improvement in their skin after using gentle products such as mild soap or acne soap.

These cleansers don’t include harsh ingredients like fragrance and alcohol, so they can effectively cleanse the skin without causing or worsening acne.

Sensitive skin

Sensitive skin can include having eczema, rosacea, psoriasis, and other skin disorders that irritate the top layer of the skin.

There’s no cure for some conditions that cause sensitive skin, but proper skin care can reduce the severity of redness, dryness, and itching.

Mild soap has a calming effect on the skin, easing inflammation. It can also act as a natural moisturizer, keeping your skin hydrated.

Itchy skin

Itchy skin can stem from conditions like psoriasis or eczema, as well as dryness. Harsh cleansers, makeup, toners, and moisturizers can cause further dryness, prolonging itchiness.

Switching to a mild soap helps to minimize dryness, leaving your skin smooth and moisturized.

Skin redness

Even if you don’t have a skin condition, you may develop skin redness after using traditional soap or cleansers. This can happen because a product is too harsh for your skin or you’re allergic to an ingredient in a product.

Switching to a mild soap can help reduce skin redness and irritation.

Side effects and precautions

Although mild soap is gentle and designed for sensitive skin, some people are sensitive to ingredients in some of these soaps.

If you use a mild soap and continue to experience skin irritation, discontinue use and speak with a doctor or a dermatologist. Signs of irritation include increased redness, itchiness, dryness, or skin peeling.

You may have better results with a hypoallergenic soap. This can safely remove excess dirt without irritation.

A doctor may also refer you to an allergist who can determine whether you’re allergic to a specific ingredient in mild soap.

Where to buy mild soap

Mild soap is available at drug stores, grocery stores, and other retailers.

As you shop for a soap, look specifically for products that are fragrant-free and alcohol-free, or soaps specifically formulated for those with hypersensitive or allergic skin.

Takeaway

Whether you have sensitive skin or you’re looking for a soap that doesn’t strip your face of natural oils and nutrients, a mild soap helps maintain your skin’s natural pH balance. As a result, you’re able to cleanse your skin while minimizing the risk of irritation.
