The Ordinary Glycolic Acid 7%: Fix Strawberry Legs & Underarms (2025)

Tired of strategically hiding your legs or feeling self-conscious about dark underarms? You're not alone, and we have good news. We're diving deep into how one incredibly affordable viral product, The Ordinary Glycolic Acid 7% Toning Solution, is the secret weapon you need for smoother, brighter skin all over.

What Is The Ordinary Glycolic Acid 7%?

This is a water-based exfoliating toner featuring glycolic acid, an Alpha Hydroxy Acid (AHA). It's designed to gently slough away the outermost layer of dead skin cells.

The formula is also supported by ingredients like Tasmanian Pepperberry to reduce irritation, and Ginseng and Aloe Vera for soothing radiance.

How It Works

• Surface Exfoliation: Glycolic acid has the smallest molecular size of all AHAs, allowing it to effectively dissolve the 'glue' holding dead skin cells to the surface. This process reveals the fresher, more radiant skin underneath.
• Unclogging Follicles: For strawberry legs (keratosis pilaris), it works by breaking down the keratin plugs that clog hair follicles. This helps to smooth out those stubborn little bumps and reduce the dotted appearance.
• Fading Hyperpigmentation: By accelerating skin cell turnover, The Ordinary Glycolic Acid 7% helps to progressively fade discoloration and dark spots, leading to a more even and brighter skin tone in areas like the underarms.

Types / Variants

While this is a single product, its genius lies in its versatility for different body concerns. Here’s how we categorize its primary uses at Glaze Theory:

Application Type	Best For	Key Benefit
For Keratosis Pilaris (KP)	Rough, bumpy 'strawberry' or 'chicken' skin on arms and legs.	Smooths skin texture by dissolving keratin plugs in hair follicles.
For Hyperpigmentation	Dark underarms, inner thighs, elbows, or bikini line.	Visibly fades discoloration and evens out overall skin tone.

How to Use The Ordinary Glycolic Acid 7%

Step 1: Preparation

Always start with clean, completely dry skin to ensure maximum efficacy. We cannot stress this enough: do not use this product right after shaving or waxing! Wait at least 24 hours to avoid significant irritation. Perform a patch test on a small area first.

Step 2: Application

Saturate a cotton pad with The Ordinary Glycolic Acid 7% Toning Solution. Gently sweep it across the target area—do not rub aggressively. We recommend starting your routine by applying it only at night, 2-3 times per week, and gradually increasing the frequency as your skin builds tolerance.

Step 3: Aftercare

Allow the solution to air dry completely. Follow up with a simple, fragrance-free body moisturizer to hydrate your skin and support its protective barrier. AHAs increase sun sensitivity, so applying a broad-spectrum sunscreen (SPF 30+) to treated areas during the day is non-negotiable.

Who Should Use It?

This product is a holy grail for anyone struggling with common body skin concerns. If you have keratosis pilaris (strawberry legs), post-inflammatory hyperpigmentation (dark spots), or uneven skin tone on your underarms, legs, or elbows, this is for you.

It's suitable for most skin types, but those with very sensitive skin should introduce it slowly and with caution.

Side Effects & Warnings

• Potential Irritation: Mild stinging, redness, or dryness can occur, especially when you first start. If it's more than mild or persists, reduce your frequency of use.
• Increased Sun Sensitivity: Your skin will be more susceptible to sunburn. Daily use of sunscreen on any exposed, treated areas is critical to protect your skin and your results.
• Who Should Avoid It: Do not apply it on broken, peeling, or irritated skin. If you have a history of eczema or rosacea in the target area, consult a dermatologist before use.

Results Timeline

Week 1: You'll likely notice an immediate improvement in skin softness. The texture of bumpy areas may begin to feel slightly smoother to the touch.

Week 4: With consistent use, you should see a visible reduction in bumps and texture. Dark spots and hyperpigmentation may start to look noticeably lighter.

Month 3: Expect a significant improvement. Skin tone will appear much more even, dark underarms will be considerably brighter, and the appearance of strawberry legs will be minimized.

Best Alternatives

• First Aid Beauty KP Bump Eraser Body Scrub: A powerful in-shower treatment that combines 10% AHA with physical pumice beads for a dual-action exfoliation.
• Naturium The Smoother Glycolic Acid Body Wash: A great alternative for those who want a gentler, daily exfoliation step integrated into their shower routine.
• AmLactin Daily Moisturizing Body Lotion: This classic lotion uses lactic acid (another AHA) to exfoliate while providing intense hydration, making it perfect for those with dry, rough skin.

FAQs

Q: Can I use The Ordinary Glycolic Acid 7% on my underarms every day?

A: We recommend starting with 2-3 times per week at night to build tolerance. Daily use can lead to over-exfoliation and irritation for many people. Always listen to your skin and reduce frequency if you notice redness or sensitivity.

Q: How long until I see results for strawberry legs?

A: You may feel smoother skin within the first week of use. However, a visible reduction in the dotted appearance of strawberry legs (keratosis pilaris) typically takes 4 to 8 weeks of consistent application.

Q: Is it normal to feel a tingling sensation after applying it?

A: Yes, a mild and temporary tingling sensation is completely normal, especially when you first start using the product. If the sensation turns into burning, persists for a long time, or is accompanied by significant redness, you should rinse the product off and use it less frequently.

Q: Can I use deodorant right after applying it to my underarms?

A: It is best to let The Ordinary Glycolic Acid 7% Toning Solution dry completely for a few minutes before applying deodorant. To be extra safe, especially if you have sensitive skin, we suggest applying the glycolic acid at night and your deodorant in the morning.

Q: The bottle says it's a facial toner. Is it safe for the body?

A: Absolutely. While it was formulated as a facial toner, its potent exfoliating properties and generous, affordable size have made it a cult-favorite for body concerns. Body skin is generally more resilient than facial skin, making this solution highly effective for issues like keratosis pilaris and hyperpigmentation on the legs and underarms.

Final Verdict

For its incredibly low price, The Ordinary Glycolic Acid 7% is a true game-changer for stubborn body concerns. It demands patience and proper aftercare (moisturizer and SPF are your best friends!), but the smooth, bright results are undeniable.

If you're ready to stop hiding your skin and start showing it off, this is one of the most effective and budget-friendly additions you can make to your body care arsenal.
