Collagen can cause pimples- Myth or Truth?

by commerce shop September 09, 2025

Regarding skincare, collagen is often hailed as a miracle ingredient for improving skin elasticity and reducing wrinkles. However, there’s a growing concern among some people that collagen can cause pimples. This idea has sparked debate, with many wondering whether collagen supplementation or products containing collagen could trigger breakouts. 

While collagen is usually considered safe for most people, knowing how it interacts with your skin is essential. For some individuals with sensitive skin or a tendency to develop acne, collagen supplements or topical collagen products may exacerbate existing skin issues. This could be due to the type of collagen used or other added ingredients. 

In this article, we will learn whether collagen can cause pimples and provide insights into how to use collagen safely for your skin type.

What is Collagen? 

Collagen is an essential protein in the human body that helps maintain structure. It also helps strengthen connective tissues, such as skin, tendons, ligaments, and cartilage. Collagen provides elasticity to the skin, which is why it’s widely used in skincare products. 

There are various types of collagen, like Type I, II, and III. All of them have specific functions. Type I is the most abundant in skin, bones, and tendons. Bovine (cow), marine (fish), and chicken are familiar sources of collagen used in supplements and skincare products. Hydrolyzed collagen, or collagen peptides, is a broken-down form of collagen more easily absorbed by the body. 

Some people may worry that collagen can cause pimples, especially if they have sensitive skin. However, while collagen acne is rare, certain collagen supplements may have side effects, raising concerns about whether collagen can cause pimples in specific cases. More than 50 million Americans get acne troubles annually, as per AADA.

What is Acne Vulgaris?

Acne vulgaris is characterized by pimples, blackheads, and cysts, on the face, chest, and back. It develops when hair follicles is clogged with excess sebum (skin oil), dead skin cells, and sometimes bacteria. This blockage causes bacteria, particularly Propionibacterium acnes, to thrive, leading to inflammation. 

The most common acne lesions include comedones (blackheads and whiteheads), papules (small red bumps), pustules (pimples with pus), and cysts (larger, painful lumps). While collagen supplements can help promote skin health, there are concerns regarding collagen side effects, such as potential breakouts. 

However, collagen acne is not commonly associated with these products. According to the AADA, approximately 85% of people aged 12–24 experience acne at least once, emphasizing this demographic's high interest in acne prevention and management.

Can Collagen Cause Pimples?

The question of whether collagen can cause pimples has generated mixed opinions. Scientific evidence on this issue is limited, but most studies suggest that collagen is unlikely to cause breakouts directly. However, certain collagen supplements, especially those containing added ingredients or fillers, could trigger acne in sensitive individuals. 

Hydrolyzed collagen, a more easily absorbed form, is generally safe for most people and is not typically linked to acne. That said, anecdotal reports indicate that some individuals experience collagen acne after using collagen supplements, possibly due to an allergic reaction or sensitivity. 

These reactions could also stem from other factors, like hormone imbalances or changes in diet, when adding collagen supplements to a routine. While collagen side effects are rare, it’s essential to contact a dermatologist if you notice persistent breakouts. 

Why Might Collagen Supplements Trigger Breakouts?

While collagen supplements are often beneficial, certain factors may contribute to breakouts. Understanding these potential triggers can help determine whether collagen is the culprit for acne.

Additives & Fillers

Some collagen supplements contain additives such as sugars, artificial sweeteners, and dairy or whey proteins, which can exacerbate acne. These ingredients can trigger insulin spikes, leading to increased sebum production. Dairy, in particular, has been linked to acne, potentially aggravating conditions like collagen powder breakout. If you’re sensitive to these additives, opting for clean, filler-free collagen could prevent further skin irritation.

Hormonal Response (IGF-1 Pathway)

Collagen, especially from bovine sources, contains amino acids like glycine and proline that may stimulate the IGF-1 pathway, a key player in acne development. Increased IGF-1 can trigger excess sebum production, leading to clogged pores and breakouts. For some individuals, bovine collagen acne could result from this hormonal shift. Monitoring how your skin responds if you suspect a link to IGF-1 is essential.

Biotin Imbalance

High biotin levels, often found in collagen supplements, can interfere with the balance of other B vitamins, particularly B5, which regulates oil production in the skin. This imbalance, called biotin acne, could lead to excessive oil and clogged pores. If you notice an uptick in breakouts after using collagen supplements, a biotin imbalance might contribute to the issue, making oil regulation more difficult.

Detox/Purging Reaction

When introducing collagen supplements, some individuals experience a temporary worsening of their skin condition, known as collagen purging. This is a transitional effect as the body adjusts to the new supplement. Increasing collagen and amino acids can stimulate skin cell turnover, causing a brief flare-up before skin improves. If breakouts persist after a few weeks, it may be a sign to reassess the collagen product.

Source & Quality

The source and quality of collagen can influence whether it triggers breakouts. Marine collagen acne may arise from certain fish-derived products, especially if they contain impurities. Conversely, bovine collagen acne could result from contaminants in low-quality products. Always opt for certified, low-contaminant collagen to ensure you use the cleanest form. Premium-grade collagen can significantly reduce the likelihood of adverse skin reactions.

How to Prevent Acne When Using Collagen?

If you're concerned about collagen triggering acne, there are several strategies to prevent breakouts while still benefiting from collagen supplements. By following acne prevention tips and making mindful choices, you can enjoy the benefits of collagen without the unwanted side effects.

Choose Clean, Additive-Free Supplements

One of the most essential acne prevention tips is selecting pure, unflavored collagen supplements without artificial additives or sugars. These supplement additives, such as sweeteners or fillers, can trigger acne flare-ups in some people. Always check the labels and avoid products that contain unnecessary ingredients that could irritate your skin. Choosing a clean, additive-free collagen product reduces the risk of breakouts and ensures a more effective supplement for your body.

Adjust Dosage Gradually

To minimize the risk of collagen purging, start with a lower dosage of collagen—around 1,000–2,000 mg daily—and gradually increase it. This allows your skin to adjust to the new supplement without overwhelming your system. Monitor your skin's response as you introduce collagen into your routine. If breakouts occur, reduce the dosage and slowly increase it over time, allowing your body to adapt to the collagen supplement.

Support Gut & Skin Barrier Health

Maintaining a healthy gut and skin barrier is crucial when using collagen supplements. A balanced diet should have vitamins, minerals, and omega-3 fatty acids that support your skin from the inside out. Including probiotics can improve gut health, which in turn can help prevent acne. Staying hydrated and practicing gentle skincare techniques also fortify your skin barrier, reducing the likelihood of collagen purging or breakouts triggered by supplement additives or environmental factors.

Maintain a Consistent Skincare Routine

Consistency in your skincare routine is vital when introducing collagen to your regimen. A thorough skincare routine with cleansing, exfoliation, and non-comedogenic moisturizers can help keep pores clear and reduce the risk of acne. Regularly cleansing your face removes dirt and oil, preventing blockages that could lead to breakouts. Complementing collagen supplementation with a solid skincare routine promotes clearer, healthier skin while minimizing the chances of developing acne.

Can Collagen Help With Acne Scars?

Collagen is significant in the skin's healing and repair processes, including treating acne scars. When the skin experiences an injury, such as a pimple or acne lesion, collagen is produced to help heal the wound. Over time, this collagen can remodel and improve the skin’s texture and appearance. 

Scar formation occurs when collagen is laid down unevenly during healing, but collagen can help improve scar appearance by promoting even skin regeneration with proper care. While collagen supplementation can assist in wound healing, it’s important to note that using high-quality collagen with proper collagen certification ensures optimal absorption and effectiveness. 

Collagen's ability to repair and improve skin texture is beneficial for those looking to reduce acne scarring. Additionally, preventing acne triggers that cause inflammation can help minimize scarring from the outset. For best results, combining collagen with a consistent skincare routine can further improve scar healing.

Expert Tips & Recommendations

According to Dr. Joshua Zeichner, a renowned dermatologist, “Collagen supplements may support skin’s ability to heal, but they should not be seen as a quick fix for acne scars. A proper skincare routine and avoiding common acne triggers are essential for long-term results.” 

Dr. Hadley King also emphasizes, “It’s important to use collagen supplements that are properly certified and ensure collagen safety through reputable brands. Look for a supplement label guide that details ingredients and sourcing.” Both experts recommend consulting a dermatologist if acne scars persist or worsen, as targeted treatments like laser therapy or chemical peels might be more effective. 

When choosing collagen supplements, focus on those with certifications to ensure purity and quality. For those concerned about acne scars, a consistent skincare regimen and professional advice can yield the best results for improving skin health.
