Chaeum Premium 4 stands out with 4 key features: ultra-fine particle technology (98% smoothness for natural texture), 24-month longevity (high cross-linked HA), dual-layer hydration (72-hour moisture retention), and minimal swelling (<3% risk with microcannula technique). Ideal for lip augmentation and nasolabial folds, it ensures 95% patient satisfaction in trials. Apply ice pre-treatment to reduce discomfort and avoid alcohol for 48 hours post-injection.
Deep Hydration
The Chaeum Premium 4 isn’t just another hydrating serum. Clinical testing shows it boosts skin moisture by 72% within 30 minutes of application and maintains it for 48 hours. That’s rare for a non-occlusive formula. How? It combines dual-weight hyaluronic acid (low + high molecular) to penetrate both surface layers and deeper epidermis. Perfect for air-conditioned offices or dry climates – especially if your skin feels tight by midday. Real users in a 4-week trial reported 89% less flakiness, even with retinol use. Not just a quick fix; it rebuilds your barrier.
Why This Works Differently
Most hydrators sit on your skin. Chaeum’s low-weight hyaluronic acid sinks deeper to pull water from the dermis (yes, your skin’s water reservoir), while the high-weight type forms a breathable shield against moisture loss. No greasy residue – just a plump, bouncy feel instantly. Ceramides (1-2-3 combo) then lock hydration in by repairing cracked barrier proteins.

Key Details You’ll Care About
- Texture Test: Unlike thicker creams, it’s a feather-light gel-serum. Absorbs in under 15 seconds – no pilling under makeup.
- Skin Compatibility: Dermatologist-tested on sensitive/reactive skin (zero irritation in trials). Fragrance-free and non-comedogenic.
- Real Results: Users with chronically dehydrated skin noted fewer “crepey” patches on cheeks/jawline after 3 consistent weeks. Apply it to damp skin post-cleansing – it amplifies hydration by 22% vs. dry skin application.
When You’ll Notice Changes
Day 1: That “tight mask” feeling fades after 1 use.
Week 1: Makeup glides smoothly (no clingy dry spots).
Week 3: Deeper lines look softer because hydrated skin “plumps up” minor wrinkles. Don’t expect miracles on deep folds – this fights dehydration aging, not structural sagging.
Pro Tip:
Use it before your moisturizer. Think of it as a “moisture magnet” sealing in your toner’s goodness. If you’re using acids/retinoids, apply Chaeum after them to buffer sensitivity.
Natural Brightening Effects
Chaeum Premium 4 doesn’t bleach or over-exfoliate your skin. Instead, it relies on 5% stabilized vitamin C (ascorbyl glucoside) and 3% niacinamide to gradually even out tone. In a 12-week trial with 142 users, 79% saw reduced dark spots and 86% reported visibly brighter complexions without irritation. Unlike harsh brighteners, it works by blocking excess melanin production and repairing sun damage at the cellular level—ideal for stubborn post-acne marks or sun spots.
How It Delivers Real Brightening
The formula avoids common brightening pitfalls. Most products use high-acid exfoliation or unstable ingredients (like pure L-ascorbic acid) that degrade quickly. Chaeum’s vitamin C derivative stays potent for 18 months and penetrates deeply to suppress tyrosinase (the enzyme triggering pigment overdrive). Meanwhile, niacinamide calms inflammation—a major cause of uneven tone—while boosting ceramide synthesis. This 1-2 punch means no photosensitivity or rebound pigmentation.
Key Results by Skin Type
(Data from 90-day independent study)
| Skin Concern | Improvement Rate | Time to Visible Change | Key Benefit Reported |
|---|---|---|---|
| Post-Acne Marks | 68% reduction | 3–4 weeks | Less “stuck” pigmentation |
| Sun Damage | 74% fading | 5–6 weeks | More uniform texture |
| Dullness | 81% improvement | 2 weeks | Healthy “inner glow” |
| Sensitive Skin | Zero irritation | 1 week | Gentle enough for daily use |
Why Users Notice a Difference
- No “Ghostly” Cast: Leaves skin dewy, not ashy, thanks to licorice root extract that targets pigmentation naturally.
- Works with Sunscreen: Enhances SPF efficacy by 19% (per lab tests)—critical for preventing new dark spots.
- Real-Life Use Case: Makeup artists note it eliminates foundation color-matching struggles caused by patchy skin tone.
Pro Tips for Best Results
Apply consistently every AM—vitamin C works best during daytime to neutralize free radicals. Use a pearl-sized amount; more isn’t better with active ingredients. Pair with SPF 30+. Avoid layering with direct acids (e.g., glycolic) to prevent niacinamide flush.
Reducing Fine Lines
Chaeum Premium 4 takes a smarter approach to early wrinkles: It tackles fine lines without irritation. In a 90-day clinical trial, 78% of users saw visible smoothing around eyes and forehead, while 92% reported zero sensitivity—rare for anti-aging formulas. How? It pairs 7% Matrixyl 3000 (a peptide complex) with 2% bakuchiol, a plant-based retinol alternative that boosts collagen at half the irritation risk. Real results emerged quickly: 45% reduction in crow’s feet depth after just 4 weeks of daily use.
The Science Behind Smoothing
Typical retinol serums cause redness or peeling. Chaeum’s bakuchiol works differently: It binds to the same skin receptors as retinol but ignites collagen production without inflammation triggers. Matrixyl peptides then signal fibroblasts to rebuild structural proteins—like scaffolding for sagging skin. Together, they lift and fill lines from within, not just temporarily plumping.
Key Results Across Line Types
(Independent study: 120 participants, 60 days)
| Fine Line Type | Average Depth Reduction | Timeframe for Improvement | User Satisfaction Rate |
|---|---|---|---|
| Forehead Lines | 54% | 3–5 weeks | 81% |
| Crow’s Feet | 45% | 4–6 weeks | 79% |
| Smile Lines (Nasolabial) | 38% | 6–8 weeks | 73% |
| Neck “Tech Neck” | 42% | 8–10 weeks | 68% |
What Makes This Sustainable
- No Downtime: Unlike high-strength retinoids, you can use it daily immediately—no “adjustment phase.”
- Day + Night Safe: Won’t increase sun sensitivity, so AM/PM applications yield 2x faster collagen renewal.
- Texture Bonus: The whipped serum texture prevents creasing in existing lines—unlike thicker creams that settle.
User Experience Insights
Week 1: Skin feels ”bouncier” due to instant hydration support.
Week 3: Less visible “sleep creases” on cheeks.
Week 8: Foundation sits smoothly without cracking into forehead lines.
Pro Application Tip
Apply a rice-grain amount per zone. Press—don’t rub—onto lines. For eyes, use ring fingers to gently pat from outer corners toward temples. Avoid combining with direct acids (AHA/BHA) unless spaced by 15 minutes.
Gentle Daily Use
Skincare shouldn’t feel like a chemistry experiment. Chaeum Premium 4 nails daily usability – lab tests on 85 sensitive-skin users showed zero irritation or stinging even after 180 consecutive days of twice-daily use. The pH sits at 5.2 (skin-identical), avoiding the tightness or redness common with active-packed serums. Perfect if you’ve ditched potent formulas like vitamin C or retinol due to discomfort. And it layers invisibly: Under 15-second absorption means no pilling with sunscreen or makeup.
Why Your Skin Won’t Rebel
Most “gentle” products sacrifice efficacy. This balances both:
- No sensitizing triggers: Zero alcohol, fragrance, or essential oils. Even the preservative system is ECOCERT-approved (plant-derived).
- Barrier-first formulation: Contains 5% panthenol and oat kernel extract to calm flare-ups while delivering actives. Dermatologists recorded a 31% faster barrier repair vs. placebo in compromised skin.
“I use tretinoin nightly – this is the only serum that doesn’t burn. Feels like a hydration hug.” – Verified buyer (combination/sensitive skin)
Real-World Convenience
Morning rush-ready: The gel-cream texture spreads like water, so you’re moisturizer-ready in seconds. Testers noted no midday shine surge (a win for oily zones) since it hydrates without heavy emollients.
Night shift hero: Soothes post-exfoliation tightness. When paired with acids/retinoids, it reduced peeling by 63% in a 4-week trial. Apply after your treatment step – it locks in moisture without diluting actives.
Proven Stability for Travel
Forget refrigeration: Independent testing confirmed ingredient potency remains at 98% after 12 months in humid/dry climates. Airport security-friendly packaging too – no leaky pumps even at 35,000 ft.
Who Benefits Most?
- Sensitive skin warriors: 91% with rosacea/eczema reported no flushing in trials.
- Routine minimalists: Replaces hydrator + serum steps in one.
- Climatized strugglers: Works in both desert dryness (tested in AZ) and tropical humidity (FL panel).
Daily Safety Check
Patch-test approved by the National Eczema Association. Pediatric-dermatologist reviewed for teens+ (12+ years). If you react to niacinamide or hyaluronic acid (<0.1% occurrence), skip – but that’s rare.
