If you follow the latest developments in skincare, you may have come across succinic acid, a multifunctional ingredient increasingly found in serums, acne treatments, masks, and moisturizers.

Best known for its potential antimicrobial and soothing properties, succinic acid may be particularly useful for blemish-prone skin. It is also being explored for its antioxidant and anti-inflammatory effects, making it an appealing ingredient for people looking to support clearer, calmer, and more balanced-looking skin.

But what exactly is succinic acid, and how does it work? Here is what you should know about this increasingly popular skincare ingredient.

What Is Succinic Acid?

Succinic acid, also known as butanedioic acid, is an organic acid that occurs naturally in living organisms and some plants. In skincare, it is used primarily for its antimicrobial, antioxidant, and potentially anti-inflammatory properties.

Unlike exfoliating acids such as glycolic acid or salicylic acid, succinic acid is not primarily used to remove dead skin cells. Instead, it is generally included in formulations designed to help maintain clearer, healthier-looking skin.

Succinic acid is sometimes compared with hyaluronic acid, but the two ingredients have very different roles. Hyaluronic acid is primarily valued for its ability to attract and retain water, helping support skin hydration and a plumper appearance. Succinic acid, on the other hand, is more commonly used in products targeting blemishes, excess oil, irritation, and overall skin balance.

Succinic acid can be produced through several manufacturing processes and may be derived from renewable sources such as plant-based materials. Beyond cosmetics, it is also used in pharmaceutical, food, agricultural, and industrial applications.

Potential Benefits of Succinic Acid for Skin

Succinic acid is attracting attention because it combines several potentially beneficial properties in a single ingredient. Depending on the formulation and concentration, it may offer the following advantages.

1. May Help Support Acne-Prone Skin

One of the most common reasons succinic acid appears in skincare products is its potential antimicrobial activity.

Certain microorganisms can contribute to an unhealthy skin environment and may play a role in blemishes. Succinic acid may help create conditions that are less favorable to some of these microorganisms, which is one reason it is incorporated into products designed for acne-prone skin.

It may also help support a more balanced appearance in oily or congested skin.

However, succinic acid should not be considered a replacement for established acne treatments. Persistent, severe, or cystic acne may require treatments recommended by a dermatologist.

2. May Help Calm the Appearance of Irritated Skin

Succinic acid also has properties that may help support the skin’s response to irritation.

For people dealing with redness or occasional sensitivity, a well-formulated product containing succinic acid may provide a gentler approach to addressing blemishes without relying solely on stronger exfoliating ingredients.

Its potential soothing properties can make it appealing to people who find some traditional acne treatments overly drying or irritating.

3. Provides Antioxidant Support

Free radicals generated by environmental stressors can contribute to oxidative stress in the skin. Over time, oxidative stress is associated with processes involved in visible skin aging, including changes in skin tone and texture.

Because succinic acid has antioxidant properties, it may help support the skin’s defenses against oxidative stress. This makes it an interesting ingredient in formulations aimed at maintaining a brighter, healthier-looking complexion.

It is important to note, however, that succinic acid should not be viewed as a standalone anti-aging treatment. Ingredients such as sunscreen, retinoids, vitamin C, and niacinamide have more established roles in many anti-aging skincare routines.

4. Can Complement a Balanced Skincare Routine

Another advantage of succinic acid is its versatility. It can be incorporated into routines designed for several different concerns, including blemishes, excess oil, dullness, and occasional irritation.

Because it is generally considered a relatively gentle ingredient, it may be easier to incorporate into a routine than some stronger exfoliating acids.

How to Use Succinic Acid

Succinic acid is commonly found in lightweight products such as serums, spot treatments, lotions, and masks.

As with any skincare ingredient, follow the directions provided by the manufacturer. In general, a serum or treatment containing succinic acid is applied to clean skin before a moisturizer.

If you are introducing a new product, begin gradually rather than immediately adding multiple active ingredients to your routine. This makes it easier to determine how your skin responds.

Using Succinic Acid for Acne-Prone Skin

If you are prone to breakouts, a simple routine can help minimize unnecessary irritation:

• Cleanse gently without aggressively scrubbing the skin.
• Apply your succinic acid product according to its instructions.
• Follow with a moisturizer appropriate for your skin type.
• Use broad-spectrum sunscreen during the day.

Succinic acid can potentially be used alongside other acne-focused ingredients, including salicylic acid, sulfur, and retinoids. However, combining several active ingredients at once can increase the risk of dryness or irritation.

If your skin is sensitive, introduce products individually and use stronger acne treatments less frequently if necessary.

Combining Succinic Acid With Other Skincare Ingredients

Succinic acid can potentially complement several other ingredients.

Hyaluronic acid can be useful when hydration is a priority, particularly for skin that feels dry or dehydrated.

Niacinamide may complement succinic acid in routines focused on oil control, barrier support, and uneven-looking skin tone.

Vitamin C can provide antioxidant support and is commonly used to address dullness and uneven pigmentation.

Retinoids are among the most established topical ingredients for addressing acne and visible signs of skin aging, although they can cause irritation when first introduced.

Exfoliating acids such as glycolic, lactic, and salicylic acid may also be used in the same overall routine, but using too many active ingredients simultaneously is not necessarily better. A carefully planned routine is generally more beneficial than layering multiple acids.

Is Succinic Acid Safe for Sensitive Skin?

Succinic acid is generally considered a relatively well-tolerated skincare ingredient, but individual reactions can vary.

People with sensitive or reactive skin should introduce new products slowly and perform a patch test when appropriate. Stop using a product if it causes persistent burning, swelling, significant redness, or other concerning reactions.

It is also worth remembering that the overall formulation matters. A product containing succinic acid may include other active ingredients, fragrances, preservatives, or exfoliants that could affect how your skin responds.

If you have a diagnosed skin condition or are undergoing treatment for persistent acne, rosacea, or another dermatological concern, consult a dermatologist before introducing multiple new active ingredients.

Succinic Acid vs. Other Facial Acids

Not all skincare acids perform the same function.

• Succinic acid: Primarily used for its antimicrobial, antioxidant, and potentially soothing properties.
• Salicylic acid: A beta hydroxy acid commonly used to exfoliate inside pores and manage acne.
• Glycolic acid: An alpha hydroxy acid used primarily for surface exfoliation, texture, and dullness.
• Lactic acid: An alpha hydroxy acid that provides exfoliation while generally being considered gentler than glycolic acid.
• Hyaluronic acid: A hydrating ingredient that helps attract and retain water in the skin.

Understanding these differences can help you choose products according to your specific skincare goals rather than simply choosing an ingredient because it is described as an “acid.”

The Bottom Line

Succinic acid is an increasingly popular skincare ingredient with several potentially useful properties. Its antimicrobial, antioxidant, and soothing characteristics make it particularly interesting for blemish-prone, oily, or irritated skin.

It is generally considered a gentle ingredient and can be incorporated into many skincare routines. However, it should not be treated as a cure-all or a substitute for clinically established treatments for persistent acne or other skin conditions.

For best results, introduce succinic acid gradually, use it as directed, and pair it with the fundamentals of good skincare: gentle cleansing, adequate moisturization, and daily broad-spectrum sun protection.
