Sodium ascorbyl phosphate for acne
Sodium ascorbyl phosphate shows in vitro and in vivo efficacy in the prevention and treatment of acne vulgaris.
Strong antimicrobial, effective treatment
We explored the potential of sodium ascorbyl phosphate (SAP), a stable form of vitamin C, in preventing and treating acne vulgaris. The study included a time-kill analysis showing that a 1% SAP formulation reduced the harmful bacteria Propionibacterium acnes by a significant log reduction of 5 after 8 hours. This demonstrates the strong antimicrobial properties of SAP against acne-causing bacteria.
Additionally, we observed an in vivo study with 20 participants, where the SAP formulation effectively prevented up to 40% of UVA-induced sebum oxidation, suggesting it can help reduce inflammation associated with acne. In another open-label study involving 60 volunteers over 12 weeks, a 5% SAP lotion was rated as excellent or good in effectiveness by 76.9% of the participants, outperforming a commonly prescribed acne treatment.
Overall, our findings indicate that sodium ascorbyl phosphate could serve as an effective, non-antibiotic option for both the prevention and treatment of acne, making it an attractive addition to cosmetic products due to its lack of side effects.

MAP reduces acne-related inflammation
Magnesium Ascorbyl Phosphate Regulates the Expression of Inflammatory Biomarkers in Cultured Sebocytes.
Relevant study on vitamin C
We aimed to explore how magnesium ascorbyl phosphate (MAP), a stable form of vitamin C, influences acne by evaluating its impact on inflammatory responses in skin cells known as sebocytes. The study employed a robust methodology, where we treated cultured sebocytes with different solutions: MAP, lipopolysaccharide (LPS), and a combination of both.
Following treatment, we measured the expression of inflammatory markers, cytokines, and proteins involved in skin inflammation and the healing process. Our findings revealed that MAP effectively reduced the heightened inflammatory responses caused by LPS, suggesting it has a calming effect on acne-related inflammation.
Additionally, we observed a notable decrease in lipid peroxidation, a contributor to skin damage, after treatment with MAP. This means that vitamin C may not only help reduce inflammation but could also protect skin cells from oxidative stress, promoting healthier skin overall.
In summary, our study strengthens the idea that using MAP can be a beneficial addition to acne treatments, potentially leading to improved skin conditions.

Acne largely controlled
Keeps my acne at bay!!! This product is a holy grail for managing my acne. While I attempt to maintain a healthy diet, I still experience back acne. However, since taking 2000-4000 mg of vitamin C daily, my skin remains 90% clear. I do get occasional acne just before my period, but I used to break out daily; this has truly cured a significant issue for me!

Vitamin C shows moderate efficacy
Efficacy of tranexamic acid solution versus vitamin C solution after micro-needling in treatment of persistent post acne erythema: a split face clinical and 3DAntera camera comparative study.
Moderate relevance to acne treatment
We explored the effectiveness of using vitamin C in treating persistent post-acne erythema, which often leaves visible redness after acne has cleared. In this study, participants received microneedling combined with either a 10% vitamin C solution or a tranexamic acid solution. The goal was to see which treatment worked better for reducing redness and improving overall skin appearance.
Four treatment sessions were spaced two weeks apart, followed by assessments two weeks after the final session. We measured improvements using clinical evaluations, 3D imaging technology to analyze blood flow in the skin, and patient feedback.
Our findings indicated that both treatments led to significant improvements in reducing skin redness. However, the tranexamic acid solution yielded even better results compared to vitamin C. Patients reported satisfaction on both sides, but they favored the effects of tranexamic acid more. Notably, any side effects were minimal and temporary.
This study suggests that while vitamin C can be helpful, using microneedling with tranexamic acid may deliver superior results for those struggling with post-acne redness.

Nutraceuticals effective for acne
Cosm-nutraceutical nanovesicles for acne treatment: Physicochemical characterization and exploratory clinical experimentation.
Study shows potential vitamin C benefits
We aimed to understand how a novel formulation combining vitamin C and quercetin can help treat acne. Our study focused on creating small liposomal structures called aspasomes that enhance the delivery of quercetin, a potent antioxidant, onto the skin.
Throughout our research, we thoroughly characterized these aspasomes for their size, stability, and how well they could penetrate the skin. One exciting finding was that these specialized nanovesicles not only preserved the antioxidant benefits of quercetin, but also demonstrated a stronger antibacterial effect against acne-causing bacteria compared to quercetin alone.
In an exploratory clinical trial involving 20 participants with acne, we observed considerable improvements. The results revealed a 77.9% reduction in inflammatory lesions and significant decreases in both non-inflammatory lesions and total acne lesions. These findings suggest that our vitamin C-based formula holds promise in managing acne and could potentially be used for other skin conditions in the future.

Vitamin C reduces facial sebum
Assessment of Combined Ascorbyl Palmitate (AP) and Sodium Ascorbyl Phosphate (SAP) on Facial Skin Sebum Control in Female Healthy Volunteers.
Vitamin C's potential impact on acne
We conducted a study to explore the effectiveness of two forms of vitamin C—ascorbyl palmitate (AP) and sodium ascorbyl phosphate (SAP)—in managing sebum production on the skin. Through a single-blinded, placebo-controlled trial involving 11 healthy female volunteers, we compared the effects of a multiple emulsion containing these compounds with a control that lacked them.
Over 90 days, participants applied the vitamin C formulation to one cheek and the control to the other. We measured sebum levels using a non-invasive device called a Sebumeter at different time intervals. Our results demonstrated that the combination of AP and SAP achieved notable antioxidant activity and effectively reduced facial oiliness compared to the control.
Ultimately, we found that incorporating vitamin C into skincare routines can be a promising solution for controlling excess facial sebum, which is often linked to oily skin and acne. However, while the study highlights the role of these antioxidants in sebum regulation, it does not provide a definitive conclusion on their isolated effects solely for acne treatment.
