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

Tired of hiding your legs because of those pesky red bumps, or feeling self-conscious about dark underarms? You're not alone. We've all been there, and the solution is surprisingly simple and affordable: The Ordinary Glycolic Acid 7% Toning Solution.

Let's break down how this cult-favorite facial toner became the holy grail for body care concerns.

What Is The Ordinary Glycolic Acid 7%?

At its core, The Ordinary Glycolic Acid 7% is a chemical exfoliant, specifically an Alpha Hydroxy Acid (AHA). Formulated for the face but embraced by the body-care savvy, it works to gently resurface the skin.

It's a water-based solution packed with 7% glycolic acid, amino acids, aloe vera, ginseng, and Tasmanian pepperberry to help reduce the irritation often associated with acid use.

How It Works

• Dissolves Dead Skin: Glycolic acid has the smallest molecular size of all AHAs. This allows it to penetrate the skin's surface and dissolve the bonds holding dead, dull skin cells together, effectively unclogging the pores that cause 'strawberry legs' (Keratosis Pilaris).
• Fades Hyperpigmentation: By accelerating skin cell turnover, it brings new, fresh cells to the surface more quickly. This process helps to visibly fade the post-inflammatory hyperpigmentation that leads to dark underarms, inner thighs, and elbow patches.
• Smooths & Brightens: Consistent exfoliation with The Ordinary Glycolic Acid 7% reveals a smoother texture and a more luminous, even-toned complexion all over your body.

Types / Variants

While there's only one version of this iconic toner, it's helpful to see how it compares to other popular chemical exfoliants from The Ordinary.

Type	Best For	Key Benefit
Glycolic Acid 7% (AHA)	Most skin types dealing with texture & dullness	Powerful surface exfoliation for overall radiance
Lactic Acid 10% (AHA)	Dry or sensitive skin	Milder, more hydrating exfoliation
Salicylic Acid 2% (BHA)	Oily or acne-prone skin	Deep pore cleansing to target breakouts

How to Use The Ordinary Glycolic Acid 7%

Step 1: Preparation

Start with clean, completely dry skin. We can't stress this enough: do not apply it right after shaving or waxing! Give your skin at least 12-24 hours to calm down to avoid major stinging and irritation. Always perform a patch test on a small area first to see how your skin reacts.

Step 2: Application

There are two easy ways to apply it to your body. You can saturate a cotton pad and swipe it over your target areas (legs, underarms, back). For a quicker, more even application, many of us at Glaze Theory pour it into a fine-mist spray bottle.

A few spritzes on your legs or arms, and you're good to go. Let it air dry and fully absorb for a few minutes.

Step 3: Aftercare

Once the solution is dry, follow up with a simple, fragrance-free body lotion to hydrate and support your skin barrier. Most importantly, AHAs make your skin more sensitive to the sun.

You must apply a broad-spectrum sunscreen with SPF 30 or higher to any treated areas that will be exposed to daylight.

Who Should Use It?

This product is a game-changer if you're dealing with common body skin concerns. It's ideal for those with Keratosis Pilaris (strawberry skin on arms and legs), hyperpigmentation (dark underarms, knees, elbows), or rough, uneven skin texture.

While suitable for most skin types, those with extremely sensitive skin should introduce it slowly.

Side Effects & Warnings

• Tingling and Redness: A slight tingling sensation upon application is normal and usually subsides. If you experience persistent burning or intense redness, rinse it off immediately.
• Increased Sun Sensitivity: This is non-negotiable. You are more susceptible to sunburn and sun damage when using this product. Sunscreen is your best friend.
• Who should avoid: Avoid using The Ordinary Glycolic Acid 7% on broken, compromised, or irritated skin. If you have conditions like eczema or rosacea in the area, consult a dermatologist first.

Results Timeline

Week 1: Your skin will likely feel noticeably softer and smoother to the touch. Don't expect dramatic visual changes just yet.

Week 4: With consistent use (2-3 times a week), you should start to see a reduction in the bumpy texture of strawberry legs. Darker areas may begin to look subtly brighter.

Month 3: This is where the magic happens. Pigmentation should be visibly lighter, and skin texture will be significantly smoother and more even-toned. Consistency is key!

Best Alternatives

• First Aid Beauty KP Bump Eraser Body Scrub: A powerful scrub that combines glycolic and lactic acids with physical exfoliating pumice beads for a dual-action treatment.
• Paula's Choice 2% BHA Body Spot Treatment: A fantastic option if your main concern is body acne or very clogged pores, as salicylic acid (BHA) exfoliates inside the pore lining.
• AmLactin Daily Moisturizing Body Lotion: A gentler approach that combines lactic acid (AHA) with deeply hydrating moisturizers, perfect for daily use on sensitive or dry skin.

FAQs

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

A: We don't recommend daily use, especially when you're just starting. Begin by applying it 2-3 times per week at night. If your skin tolerates it well after a few weeks, you can consider increasing the frequency, but listen to your skin to avoid over-exfoliation and irritation.

Q: Does glycolic acid really help with dark underarms?

A: Yes, it's one of its most popular off-label uses! Dark underarms are often caused by a buildup of dead skin cells and hyperpigmentation. Glycolic acid exfoliates the surface, speeds up cell turnover, and helps fade this discoloration over time, leading to a brighter, more even skin tone.

Q: How long does it take to see results for strawberry legs with The Ordinary Glycolic Acid?

A: You can expect to feel a smoother skin texture within the first 1-2 weeks. However, visible reduction in the appearance of clogged pores and redness (the 'dots' of strawberry legs) typically takes 4-8 weeks of consistent use. Full results are often seen around the 3-month mark.

Q: Can I use The Ordinary Glycolic Acid 7% with deodorant?

A: Absolutely. Apply The Ordinary Glycolic Acid 7% to clean, dry underarms at night and let it absorb completely for a few minutes. Afterward, you can apply your deodorant as usual. Some people even find the glycolic acid helps reduce body odor.

Q: Is it safe to use The Ordinary Glycolic Acid 7% on the bikini line?

A: Yes, it can be very effective for preventing ingrown hairs and discoloration on the bikini line. However, this is a sensitive area. Be sure to patch test first, avoid applying it immediately after shaving or waxing to prevent stinging, and be very careful to keep it on the external skin only, avoiding mucous membranes.

Final Verdict

The Ordinary Glycolic Acid 7% Toning Solution has earned its legendary status for a reason. It's an incredibly effective, multi-purpose, and budget-friendly workhorse for tackling stubborn body concerns like strawberry legs and dark underarms.

As long as you introduce it carefully, moisturize, and commit to daily sunscreen, you'll be on your way to smoother, brighter skin. It's a definitive Glaze Theory must-have.
