The right combination of active ingredients is key to achieving effective, healthy skincare results. One powerful duo that’s been gaining popularity in skincare routines is glycolic acid and vitamin C. But combining these two actives requires thoughtful application to avoid irritation and ensure maximum benefit. Let’s dive into what makes this pair effective—and how to use them safely.
What Is Glycolic Acid and How Does It Work on Skin?
Glycolic acid is a type of alpha hydroxy acid (AHA) known for its ability to exfoliate the skin by gently dissolving the bonds between dead skin cells. Its small molecular structure allows it to penetrate quickly, promoting smoother texture, brighter tone, and cell renewal.
If you’ve ever asked, “What does glycolic acid toner do?”, here’s your answer: it helps minimize pores, smooth texture, and even skin tone.
One standout option is The Purest Solutions Revitalising Glycolic Acid Blue Toner, formulated to reduce the appearance of pores and support skin clarity. With a blend of AHA concentrate, glycolic acid, and prebiotic humectants like inulin and fructose, it not only exfoliates but also helps rebalance the skin microbiome. Due to its low pH, sensitive skin types should introduce it gradually.
Which Comes First: Glycolic Acid or Vitamin C?
In any skincare routine, order matters—especially when layering active ingredients.
Start with glycolic acid toner to exfoliate and prep the skin. Once the skin is clean and balanced, follow up with your vitamin C serum. This sequence allows vitamin C to absorb more effectively into freshly exfoliated skin.
- Wait a few minutes between applications to let pH levels stabilize
- For sensitive skin, consider using glycolic acid and vitamin C on alternate nights to minimize irritation
Benefits of Using Glycolic Acid + Vitamin C Together
When used correctly, this combo offers powerful skin-brightening and anti-aging benefits:
-
Smooths uneven skin tone
-
Reduces fine lines and dullness
-
Boosts overall radiance and glow
However, both ingredients are potent exfoliants, and overuse can lead to redness or sensitivity—especially if your skin barrier is already compromised. Always pair them with a hydrating moisturizer to maintain balance.
One example: The Purest Solutions Brightening & Skin Tone Correcting Vitamin C Serum with ferulic acid, hyaluronic acid, and glycerin delivers antioxidant protection while replenishing moisture—helping prevent irritation from actives.
Important: Always apply broad-spectrum SPF in the morning after using either glycolic acid or vitamin C, as both increase sun sensitivity.
Mistakes to Avoid When Combining Glycolic Acid and Vitamin C
Some common missteps to steer clear of:
-
❌ Applying both ingredients back-to-back in high concentrations
-
❌ Skipping moisturizer in between
-
❌ Using multiple other actives (like retinol or salicylic acid) in the same routine
Instead, try sandwiching them between hydrating steps—and if your skin shows signs of irritation, reduce frequency immediately.
Pro tip: Start slow, especially if you’re new to actives. Try alternating nights or using glycolic acid just 2–3 times a week until your skin builds tolerance.
Tailoring This Duo for Your Skin Type
Every skin type responds differently to actives. Here’s how to adjust:
Oily & combination skin:
-
Benefit most from glycolic acid’s ability to reduce excess oil and refine pores
-
Can often use glycolic acid up to 3x per week
Dry or sensitive skin:
-
Should introduce glycolic acid slowly and layer with hydrating serums and creams
-
Vitamin C is generally safe for all skin types, but start with lower concentrations if irritation occurs
🧳 For travel: The Purest Solutions Vitamin C Serum – Travel Size is a great option for maintaining your routine on the go.
And no matter your skin type: never skip SPF when using these actives.
