Know Your Skin. Care with Purpose — Protect What Matters Most
Your skin is unique, with its own strengths and vulnerabilities. After prevention and correction, the final — and ongoing — step is protection. Shielding your skin from UV damage, pollution, and other environmental stressors is essential to preserve the results you’ve achieved and maintain its long-term health.
At LSI, we combine dermatological expertise with science-based solutions to ensure your skin remains healthy, resilient, and radiant.
Because protecting your skin is not just the last step — it’s the step you take every day.
🔬 Consult your dermatologist and choose the protection your skin truly needs.

Know Your Skin for Effective Care
Your skin is unique — with its own history, needs, and responses. Understanding it is essential to choosing the right treatment.
At LSI, we provide advanced dermatological solutions tailored to address specific conditions — from pigmentation concerns and premature aging to loss of firmness and sensitive skin. But the most important step remains the same: always consult your dermatologist.
Together with expert guidance, our science-based products help you achieve healthier, more resilient skin — because the right care starts with knowledge.
🔬 Know your skin. Care with purpose.

Care with Purpose: Prevent. Correct. Protect. ✨
Healthy, resilient skin begins with a consistent skincare routine
✅ Prevent — Daily habits such as consistent broad-spectrum sun protection, a balanced diet, and avoiding harmful environmental exposure are the foundation for maintaining skin integrity and slowing premature aging.
✅ Correct — When concerns arise, from pigmentation to early signs of aging, targeted dermatological treatments tailored to your skin's unique needs can restore balance, improve texture, and address specific issues effectively.
✅ Protect — Safeguarding your skin against UV rays, pollution, and oxidative stress — while reinforcing its natural barrier — ensures that the results of prevention and correction last over time.
At LSI, we believe in intentional, science-driven, and personalized care.
🔬 Know your skin. Care with purpose. Consult your dermatologist.

July is Melasma Awareness Month 🌗
Melasma is more than just a skin concern — it impacts confidence and quality of life.
This month, we raise awareness, share knowledge, and support real solutions.
Let’s talk openly. Let’s treat professionally.
Let’s support each other.
🔹 Myth 5: “One treatment is enough”
Melasma requires ongoing management. Even after visible improvement, flare-ups can occur — especially with sun exposure. A long-term treatment plan is essential to maintain results.
🔹 Myth 6: “If you already have melasma, sunscreen won’t help”
This is a misconception. Daily use of broad-spectrum sunscreen (SPF 30 or higher) is a cornerstone of melasma care — it prevents further darkening and supports treatment effectiveness.
🔹 Myth 7: “Scrubbing or exfoliating helps fade melasma”
On the contrary, aggressive exfoliation can worsen the condition. Melasma care requires gentle skincare and targeted, dermatologist-approved treatments.
✨ With Tranacix, LSI joins the mission to treat melasma with science and care.
16/07/2025
Let’s debunk 7 common myths about melasma 🙌
🔸 Myth 1: “Melasma can’t be treated”
This is incorrect. Even in persistent cases, melasma can be improved with appropriate dermatological guidance and a personalized treatment plan.
🔸 Myth 2: “Melasma is caused by poor hygiene”
Melasma is not related to hygiene. It is primarily influenced by sun exposure, hormonal changes, genetics, and certain medications.
🔸 Myth 3: “Melasma is permanent”
While melasma can be recurrent, it often improves significantly with consistent care, sun protection, and the right topical or in-office treatments.
🔸 Myth 4: “Only women develop melasma”
Although melasma is more common in women, men can also be affected. It is a condition that can impact anyone, regardless of gender.
✨ Understanding the facts is the first step toward effective care.
📌 Consult your dermatologist for a personalized melasma treatment plan.
