Best Vitamin C Soaps -Benefits, Side Effects & How to Use 

The most common form of Vitamin C being used in skincare today is Vitamin C serum. But did you know that there are also Vitamin C soaps that are super easy to use and great for your skin as well? 

I have recently realized that these are a thing and I was excited to see how they work. I had questions: Do the work the same or faster? Do they have more or fewer side effects? Are they safe? So, let’s see what I was able to find out. 

What Vitamin C Is & What It Does For The Skin

Vitamin C, also known as Ascorbic Acid, is an antioxidant that has great benefits for your body and your skin. 

Our bodies cannot produce Vitamin C by itself so we need to obtain it from external sources (mainly through food and in skincare). It is most commonly used in skincare to combat the effects of photo-aging and free-radical damage on the skin.

Benefits Of Using Vitamin C Soaps

Just like Vitamin C serums and lotions, Vitamin C soaps are great for the skin. Benefits of Vitamin C Soap include:

1- Lighten Skin & Reduce Dark Spots and Scars

Vitamin C soap will gradually lighten your skin and even help to reduce dark spots, scars, and marks such as acne scars.

Vitamin C works to lighten your skin by inhibiting tyrosinase which affects melanin production in the skin. It also fights free radicals which cause sun damage that darken and age the skin. These actions, combined, will gradually lighten and brighten your skin.

2- Nourishing and Cleansing 

A Vitamin C soap will deliver Vitamin C into the skin while also cleansing. If you do not like the feel of serums and lotions on your skin, soaps are a great way to deliver certain ingredients to your skin. It is usually washed off after a few minutes of absorption. 

3- Easy on sensitive skin

Vitamin C soaps are also great for people with sensitive skin that find leave-on vitamin C serums and lotions too harsh on their skin. Since the soap is washed off, it will be less irritating to the skin.

4- Effective in the same way as lotions and serums

The Vitamin C in the soap will work in the same way as the serums and lotions. It will still be able to help with all the same skin concerns (aging, spots, hyperpigmentation, hydration, collagen formations, etc).

5- Easier to use on large areas of the body

Serums and lotions can come in small portions that make it just not feasible to use them all over your body as you need. Soaps, however, are much more sustainable, and 1 bar (depending on the size) will last you at least 2 weeks even if you use it every day. They are usually very sudsy, making the product easier to spread all over your skin as needed. 

6- Affordable

Vitamin Soaps are usually more affordable than Vitamin C serums and lotions. However, this can vary depending on the brand that you are using. However, since it lasts longer, it works out to be more affordable in the long run (at least for me). 

If you suffer from acne then I recommend using these soaps:

How To Use Vitamin C Soaps

Vitamin C soaps can be used all over the skin externally like regular soap (but you need to avoid getting in private areas).

When to use

You can use Vitamin C soap in the morning, at night, or both. 

This will vary depending on what you are treating and how your skin reacts to the soap. Remember that Vitamin C is an active ingredient that is safe for use in the day but you still need to wear your SPF and moisturize. 

Some people believe that using it at night is better because your skin is free from makeup and other products, which makes it easier for the skin to absorb it. However, there is no clinical proof that one time is better than the other.

How often to use a Vitamin C Soap

I recommend that you start by using vitamin C soap 2-3 times per week first, then gradually increase the frequency. 

If you have sensitive skin, or if you are not sure how your skin will react to the soap, do a patch test and start gradually. While this will take a while, it will give your skin time to adjust. 

In between uses, ensure to moisturize well. This will also help to prevent irritation and side effects. As you use the soap, you can gradually increase your frequency until you can use it every day.

Can You Use Vitamin C Soap Everyday

You can use Vitamin C soap daily once your skin can handle it. This is why it’s best to start off using it 2-3 times a week to see if your skin can handle it and then gradually increase how often you use it.

Choosing the right soap

When choosing a soap, look for one that will have a suitable concentration of Vitamin C and one that is devoid of harsh or drying ingredients. 

Remember that soaps, because of their formulation, have the capability of drying out your skin. It can also easily irritate your skin because soaps are designed to dissolve oils from your skin (stripping). The oils usually form a protective barrier over and around your skin cells, keeping them nice and moisturized. 

However, dry skin cells are easily irritated, which can cause skin damage.

If you already have dry or sensitive skin, avoid using soaps with ingredients like sodium lauryl sulfate (SLS), fragrances, ethyl, alcohol, and synthetic colors or dye. Instead, look for soaps that contain plant oils (olive oil, jojoba oil, cocoa butter, etc), glycerin, lanolin, and/or hyaluronic acid. These can help to moisturize your skin. 

If you are using Vitamin C soap with other active ingredients like kojic acid, or retinol, ensure that the concentrations are suitable as too much can irritate your skin. 

I recommend talking to your dermatologist about using soaps like this based on the condition of your skin.

Frequently Asked Questions (FAQs)

Does Vitamin C soap treat acne?

Vitamin C has some anti-inflammatory properties that can make it helpful in reducing the swelling, redness, and inflammation that occur with cystic acne, but most doctors will not use Vitamin C to actually treat acne. 

Vitamin C also increases collagen production which helps in the healing of acne lesions and in the structural repair of the skin. Its brightening properties help to treat acne scars and hyperpigmentation that many acne-probe people have the misfortune of dealing with. 

Can you use Vitamin C soap on your face?

Yes, you can use Vitamin C soap on your face. However, the reaction of your skin will depend on how strong the soap is, the other ingredients in the soap, and how sensitive your skin is. 

I recommend checking your soaps to make sure there are no ingredients in them that are toxic, irritating, drying, or too harsh for your skin. Also, check that the concentration of Vitamin C is suitable. 

Always patch-test your skin before applying any treatment all over. 

Can you use Vitamin C soap on your private areas?

You can use Vitamin C soaps on the external skin of your private areas, but you should make sure not to get it on the sensitive, internal areas (soft, mucosal skin). 

The ingredients in these soaps may be too harsh for your skin and can unbalance the pH of your private areas. This is very important for preventing infections and irritation.

Side Effects Of Using Vitamin C Soaps

Generally, Vitamin C is very safe to be used topically. However, if applied in too high concentrations or if the soap has other drying ingredients, it can cause dryness and irritation, especially if used with other acids.

In most clinical studies, it is shown that Vitamin C is safe for the skin in concentrations up to 10% without having side effects. 

This can be different based on how sensitive your skin is and the other ingredients you use in your routine. However, I recommend that you patch test your skin first, and you start with a relatively low concentration first to familiarize your skin with the ingredient. 

If you notice that you are having redness, stinging, bumps, itching, or pain around the area where you are using the soap, try moisturizing more often, lessening the concentration that you are using, and/or lessening the frequency of use.

If none of these methods helps, then you may need to re-evaluate your skincare routine to see whether other ingredients are reacting with Vitamin C, or if you need to consider other options.
