• Soothing Agents: Tasmanian pepperberry (reduces inflammation), ginseng root (brightens), and aloe vera (calms) .

Table: Key Specifications

Attribute	Detail	Significance
Concentration	7%	Effective yet tolerable for most non-sensitive skin
pH Level	3.6	Maximizes exfoliation power

Ideal Frequency: Science-Backed Guidelines

How Many Times to Use The Ordinary Glycolic Acid: Dermatologist Recommendations

Standard Protocol for Face and Neck

• Beginners: Start with 1x/week (e.g., Wednesday evenings) .
• Tolerant Skin: Gradually increase to 2–3x/week after 2–4 weeks .
• Advanced Users: Maximum 4x/week—never daily. Always skip days to let skin recover .

“Overuse thins the skin, causing redness and sun sensitivity. Twice weekly is my cap for sensitive types.” — Dr. Angela Tewari, Consultant Dermatologist .

Scalp and Body Applications

• Scalp: Apply to dry scalp 1–2x/week for 10 minutes pre-shampoo to reduce flaking .
• Underarms: 2–3x/week to combat odor (pH balancing) and dark spots. Avoid after shaving .
• Heels/Elbows: Daily for 7 days to soften cracks, then maintain 2x/week .

Critical Factors Influencing Your Frequency

What Changes How Often You Should Use Glycolic Acid?

Skin Type and Sensitivity

• Oily/Resilient Skin: Tolerates 3–4x/week .
• Dry/Combination: Limit to 1–2x/week with added hydration .
• Sensitive/Rosacea-Prone: Patch test first. Use 1x/week or switch to lactic acid .

Product Format Considerations

The Ordinary’s leave-on toner is stronger than rinse-off glycolic cleansers. Adjust usage accordingly :

Glycolic Product Type	Max Weekly Frequency
Toner (Leave-on)	3–4x
Cleanser (Rinse-off)	Daily
Serum (High %)	1–2x

Layering with Other Actives

• Avoid Combining With:
• Retinol
• Vitamin C
• Other AHAs/BHAs (e.g., salicylic acid) .
• Alternatives: Use glycolic acid nights on Mondays/Thursdays and retinol on Tuesdays/Fridays .

Step-by-Step Routine for Safe Application

How to Use The Ordinary Glycolic Acid Toner Correctly

1. Cleanse: Wash face with gentle, non-exfoliating cleanser. Dry skin completely .
2. Apply:

• Face: Soak cotton pad, swipe over face/neck. Avoid eyes!
• Scalp/Body: Apply directly or spray .

1. Wait: Let absorb 10–15 minutes before next step .
2. Hydrate: Follow with hyaluronic acid serum (e.g., The Ordinary HA + B5) .
3. Moisturize: Seal with ceramide cream (e.g., Natural Moisturizing Factors + PhytoCeramides) .
4. Morning After: Always apply SPF 30+. Glycolic acid increases UV sensitivity by 48% .

Pro Tip: Dilute with water if stinging occurs. Redness beyond 10 minutes signals over-exfoliation .

Side Effects: Signs You’re Over-Using It

When to Cut Back: Red Flags

• Mild: Tingling (normal), temporary flush .
• Moderate: Peeling, tightness, or increased breakouts (purging) lasting 4–6 weeks .
• Severe: Burning, persistent redness, or swelling → Stop immediately! .

“Purging is normal; irritation is not. Listen to your skin.” — Dr. Dev Patel, Dermatologist .

Solution for Over-Exfoliation:

• Pause glycolic acid for 2 weeks.
• Switch to barrier-repair ingredients (ceramides, squalane).
• Reintroduce at half prior frequency .

FAQs: Your Top Questions Answered

Common Glycolic Acid Frequency Questions

Can I use it daily?

No—daily use risks barrier damage. The Ordinary explicitly advises against applying on “sensitive, peeling, or compromised skin” .

How long until I see results?

• Brightness/Texture: 2–4 weeks with 2x/week use .
• Hyperpigmentation/Acne: 8–12 weeks .

Can I pair it with vitamin C?

Use vitamin C in mornings and glycolic acid on alternate nights. Never layer together—pH conflicts reduce efficacy .

Is it safe during pregnancy?

Consult your OB-GYN. AHAs lack safety data for pregnancy; many derms recommend pausing .
