Benefits of Lirene Acid Power Moisturising 7% Serum

• Gentle Exfoliation: The 7% AHA/PHA acid blend dissolves dead skin cells and accelerates cellular turnover, revealing fresher, smoother skin underneath.
• Anti-Wrinkle Action: Lactic Acid and Lactobionic Acid stimulate collagen support and skin regeneration, reducing the depth and visibility of fine lines and wrinkles.
• Radiance Boost: Phytic Acid and Vitamin C target uneven pigmentation, helping to achieve a visibly brighter, more luminous complexion.
• Deep Hydration: Hyaluronic Acid retains water in the deeper layers of the skin, improving elasticity and leaving skin plump, soft, and revitalised.
• Skin Renewal: Regular use (2–3 times per week in the evening) progressively improves overall skin texture, tone, and firmness.

Precaution: Always apply broad-spectrum SPF the morning after AHA use. Perform a patch test before first use. Mild purging may occur in the first 2–4 weeks. Avoid during pregnancy or nursing without medical advice.

How to Use Lirene Acid Power Moisturising 7% Serum

1. Perform a patch test on the inner arm 24 hours before first facial use.
2. Cleanse and dry your face thoroughly in the evening before application.
3. Apply a small amount to the face, neck, and décolletage, avoiding the eye area.
4. Leave on for 20 minutes as an active treatment, then rinse — or leave overnight for deeper action.
5. Use 2–3 times per week; always apply broad-spectrum SPF 50 the next morning to protect acid-sensitised skin.

Note: New users should start with once-weekly use and increase gradually based on skin tolerance. Stop use if persistent irritation occurs.

Q1: Why do I need to use sunscreen after this serum?

AHA/PHA acids increase the skin's sensitivity to UV radiation by removing the uppermost layers of dead skin cells. Applying a broad-spectrum SPF 50 every morning after use is mandatory to prevent sunburn and protect against photoageing.

Q2: What is skin purging and is it normal?

Purging is a temporary period (usually 2–4 weeks) where accelerated cell turnover brings congestion to the surface faster than normal. It manifests as small whiteheads or increased breakouts in areas you usually break out. If blemishes appear in new areas or persist beyond 4–6 weeks, discontinue use.

Q3: Can I use this serum if I am pregnant or breastfeeding?

Use of AHA-containing products during pregnancy or nursing is not recommended without first consulting a doctor or dermatologist.

Q4: How soon will I see results?

Most users notice improved skin texture and radiance after 2–4 weeks of regular use, with more significant reduction in fine lines and pigmentation visible after 8–12 weeks.

Q5: Can I use it with other active ingredients?

Avoid layering with other strong actives (retinoids, vitamin C serums, or physical scrubs) on the same evening. Use on alternating nights to minimise irritation risk.
