Welcome to Beautyistic — where beauty meets science and real results matter. Let’s talk about something so many of us struggle with even after our breakouts fade: those stubborn dark marks and uneven tone that just won’t budge. Today, we’re taking a closer look at the Proactiv Post Blemish 10% Vitamin C Serum — a dermatologist-developed formula designed for acne-prone skin that promises brighter, smoother, and more even-looking skin without the worry of clogged pores.
This serum is lightweight, fragrance-free, and fast-absorbing — which is already a win for anyone who dislikes that sticky vitamin C feel. It’s powered by 10% pure Vitamin C, paired with hyaluronic acid for hydration and Centella Asiatica extract — a calming antioxidant known for soothing irritation and strengthening the skin barrier. Together, these ingredients target post-acne marks while protecting the skin from daily environmental stressors that can make discoloration worse.
In my real-world testing, I incorporated this serum into my morning routine right after cleansing and toning. I let it sink in for about a minute before following with my moisturizer and SPF. The texture felt silky but not greasy — it melted into my skin quickly, leaving a soft, matte finish that worked beautifully under makeup. Over two weeks of consistent use, I noticed my complexion looking more even, and those pesky post-breakout spots started to fade subtly but noticeably.
What really stood out to me was how gentle it felt. Many Vitamin C serums can sting or feel harsh, especially on acne-prone or recently healed skin, but this one didn’t cause any irritation or redness. However, it’s worth noting that while it brightened my skin tone over time, it’s not a quick-fix product — you’ll need consistent use to see the full benefits.

Back to the serum — let’s break down what works and what could be better. On the pro side, it’s beautifully formulated for sensitive, acne-prone skin. It’s fragrance-free, doesn’t pill under other products, and layers seamlessly in a morning routine. The inclusion of Centella Asiatica is a smart move — it’s a skin-calming powerhouse that supports repair. The only con for me? The packaging could do with a little more opacity to better preserve the Vitamin C potency over time, since light exposure can degrade it.
When it comes to value, this serum lands in the mid-range category. Considering it’s dermatologist-developed and uses a stabilized form of Vitamin C with supportive ingredients like hyaluronic acid and Centella, I’d say it delivers fair value for the price — especially compared to high-end alternatives that cost twice as much but offer similar formulations.
If I were to compare, it’s a step gentler than something like SkinCeuticals’ C E Ferulic, and less oily than La Roche-Posay’s Pure Vitamin C10 serum. It’s ideal for those who want brightening benefits without the potential irritation or heavy finish.
The build quality is what you’d expect from Proactiv — simple, clinical-style packaging that’s functional and easy to use. The pump dispenses just the right amount without waste, and after several weeks, I didn’t notice any oxidation or color change, which speaks well to its stability.
While I didn’t have to reach out to customer service personally, Proactiv’s reputation for responsive support and clear skincare guidance remains consistent — which adds confidence for those new to active ingredients like Vitamin C.
Overall, the Proactiv Post Blemish 10% Vitamin C Serum does what it promises — it helps fade dark marks, smooth uneven tone, and hydrate without irritation. It’s not the most potent Vitamin C out there, but that’s what makes it perfect for acne-prone or sensitive skin types who want visible improvement without risk.
If you’re new to Vitamin C or have struggled with breakouts and need a serum that’s gentle yet effective, this is a strong contender. If your skin’s already tolerant to stronger actives and you’re chasing dramatic brightening, you might explore more concentrated or multi-antioxidant blends instead.
