IOPE Retinol Super Bounce Serum — Rétinol Quadruple Effet Rebond

Retinol RX™ Quadruple Complex 1% combines four forms of retinoids : pure retinol, encapsulated retinol, Granactive Retinoid™ (Hydroxypinacolone Retinoate), and Bio-Seletinoid™. This structure allows for staggered release — some act quickly on cell renewal, others diffuse gradually to support collagen synthesis. In vitro studies show that Hydroxypinacolone Retinoate outperforms classic retinol and retinyl palmitate at equal concentrations, with superior light stability.

Retinol (Retinol, 509 IU/g): the gold standard of anti-aging actives. Stimulates collagen production, accelerates cell turnover, reduces fine lines, and evens skin texture. The microbiome ingredient Lactobacillus Ferment Lysate strengthens the hydration barrier, allowing for better tolerance.

Madecassoside : a soothing derivative of Centella asiatica. Calms micro-inflammations, supports tissue repair — essential to counterbalance the potential sensitivity of retinol.

Squalane + Shea Butter (Butyrospermum Parkii Butter): an emollient duo that locks in hydration, prevents dryness often associated with retinols. Melting texture, fast absorption.

Hinoki Cypress Leaf Extract (Chamaecyparis Obtusa Leaf Extract): Japanese tradition adapted to Korean skincare. Soothing and antioxidant properties, provides a velvety fresh sensation.

☀️ Morning routine

1. Cleanse your face with a gentle cleanser
2. Apply your lotion or hydrating essence
3. Apply 1 to 2 pumps of serum over the entire face, avoiding the immediate eye area
4. Gently pat until fully absorbed
5. Layer your moisturizer
6. Always finish with SPF30+ sunscreen — retinol increases photosensitivity

🌙 Evening routine

1. Double cleanse (oil then gel/foam) to remove impurities and makeup
2. Toning lotion to rebalance pH
3. 1 to 2 pumps of IOPE serum on slightly damp skin to promote absorption
4. Wait 1 minute before sealing with a rich cream or sleeping mask

Formulated for daily use morning and evening without an adjustment period, which is rare for 1% retinol. If you’re starting out, begin with 3 nights a week then gradually increase.

• Skin seeking visible firmness : clinical tests after 4 weeks show +12.2% elasticity in the skin's elastic layers, a redefined facial contour, skin that "bounces back" to the touch
• Demanding retinol beginners : you want the effectiveness of real retinol without the drawbacks (peeling, redness). This quadruple formula ensures optimal tolerance, suitable even for daytime use
• Skin with enlarged pores and uneven texture : –21.3% pore count and –14.2% texture roughness after 4 weeks
• Dull complexions seeking dense radiance : the "Super Bounce" effect plumps from within thanks to combined hyaluronic acids, for natural brightness
• Mature skin or preventive anti-aging 30+ IOPE has been researching retinol since 1997 : , each formulation inherits this scientific expertiseAvoid if:

You are pregnant or breastfeeding (retinol contraindication). Skin with active eczema or severe rosacea (prioritize healing treatments first). Tu es enceinte ou allaitante (contre-indication rétinol). Peau présentant de l'eczéma actif ou de la rosacée sévère (privilégie d'abord des soins cicatrisants).

From 1 week: elasticity and firmness visibly improved, skin more supple upon waking, expression lines softened around the eyes.

After 2 weeks: refined skin texture, smoother surface, less visible pores — especially in the T-zone. More even complexion, post-blemish marks faded.

After 4 weeks: measured reduction in wrinkles: –10.6% nasolabial folds, –8.5% frown lines, –7.0% crow’s feet, –8.8% forehead wrinkles. The facial contour is redefined, the skin appears "plumped" — natural lifting effect without injections.

Continuous use (8-12 weeks): restored skin density, radiant complexion without makeup, velvety texture to the touch. Clinical tests indicate a visual reduction of 1 year in skin age. This serum does not promise an instant miracle: it gradually rebuilds the dermal matrix, with consistent results that pay off.

Ce sérum ne promet pas de miracle instantané : il reconstruit la matrice dermique progressivement, avec une régularité qui paie.

Can I use this serum morning AND night right from the start?

Yes, this serum is designed for daily use morning and night without an adjustment period, unlike classic retinols. Its optimal tolerance allows for this. However, if your skin is very sensitive or you have never used retinol, start with 3 nights per week then gradually increase. And in the morning, SPF50 is non-negotiable.

What is the difference with a 0.1% or 0.3% retinol?

This serum contains 1% Retinol RX™ — a high concentration. But thanks to the quadruple complex (pure retinol + encapsulated + Granactive + Bio-Seletinoid), the effectiveness is boosted without irritation spikes. A classic 0.3% retinol can be more aggressive than a well-formulated 1% like this one. Encapsulation and gradual release make all the difference.

What texture: gel, oil, cream?

Silky, light gel-water texture that melts instantly into the skin. Zero greasy film, zero sticky effect — the skin is soft, almost invisible after 1 minute. Ideal for layering other treatments or makeup in the morning.

Can I combine it with vitamin C or AHA/BHA acids?

Yes, but with strategy: vitamin C in the morning (before retinol + SPF), AHA/BHA in the evening 2-3 times/week alternating with retinol (not the same night at first). Once your skin is used to it (after 4-6 weeks), you can try the same routine — but listen to your skin. If tightness or redness occurs, space out the actives.

How long does the 50ml bottle last?

With 1 to 2 pumps morning and night, the bottle easily lasts 2 to 3 months — a little product covers the entire face. Excellent quantity/price ratio for a premium retinol serum.

Is this serum suitable for oily, acne-prone skin?

Absolutely. Retinol regulates sebum production, unclogs pores, speeds up healing of post-acne marks. The light texture does not overload combination/oily skin. Just avoid applying it on active inflamed pimples — wait until they are in the healing phase.
