Benefits of Lirene Acid Power Smoothing Serum

• Exfoliation & Renewal: The 7% AHA blend dissolves bonds between dead skin cells, accelerating turnover to reveal a smoother, fresher surface underneath.
• Wrinkle Reduction: Glycolic and lactic acids stimulate the skin's natural regeneration process, visibly softening fine lines and improving skin firmness over time.
• Brightening Effect: Regular exfoliation reduces post-inflammatory hyperpigmentation and acne scars, giving the complexion a more even, radiant appearance.
• Deep Hydration: Rose hydrolate, lactic acid, and sodium hyaluronate work together to maintain optimum moisture levels for plump, comfortable skin.
• Antioxidant Protection: Succinic acid neutralises free radicals, defending skin cells from oxidative damage that contributes to premature ageing.

Precaution: Apply broad-spectrum SPF 50 every morning after use. Perform a patch test before first use. Mild purging may occur in weeks 1–4. Not for use during pregnancy or nursing without medical advice.

How to Use Lirene Acid Power Smoothing Serum

1. Perform a patch test on the inner arm 24 hours before first facial use.
2. Cleanse and fully dry your face before application in the evening.
3. Apply a small amount to the face, avoiding the eye and lip areas.
4. Massage gently and leave on for 20 minutes before rinsing, or leave overnight for deeper exfoliation.
5. Use 2–3 times per week; always apply a broad-spectrum SPF 50 the next morning.

Tip: Begin with once-per-week use and increase frequency gradually as your skin adapts. Discontinue if persistent irritation, stinging, or inflammation occurs.

Q1: Is SPF mandatory after using this serum?

Yes — glycolic acid in particular significantly increases UV sensitivity. Applying a broad-spectrum SPF 50 every morning after evening use is essential to prevent sunburn, photodamage, and worsening pigmentation.

Q2: Will I experience purging?

Some users experience a temporary purging phase during the first 2–4 weeks where congestion surfaces faster than usual. This is a normal response to accelerated cellular turnover and should resolve on its own. If new breakouts appear in unexpected areas or persist beyond 4–6 weeks, stop use and consult a dermatologist.

Q3: Is it safe to use during pregnancy or breastfeeding?

Use of AHA serums during pregnancy or nursing is not recommended without prior consultation with a doctor or dermatologist.

Q4: Can I use this serum every day?

No — start with 2–3 times per week in the evening to allow the skin barrier to adapt. Overuse can cause excessive dryness, sensitivity, or irritation.

Q5: How does glycolic acid reduce wrinkles?

Glycolic acid — the smallest AHA molecule — penetrates deeply to stimulate production of skin barrier proteins and glycosaminoglycans that fill fine lines from within, resulting in visibly plumper, smoother skin over consistent use.
