Deep Hydration
Plump, Dewy Hydration
Our multi-weight Hyaluronic Acid serum delivers intense hydration at every layer of the skin. The lightweight, water-based formula absorbs instantly, drawing moisture to the skin and locking it in for lasting plumpness and a dewy, healthy glow.
Clinically Formulated
The Science
Multi-Layer Hydration Technology
Three molecular weights for complete hydration
High Weight HA
Sits on the skin surface to prevent moisture loss and provide an instant plumping effect.
Medium Weight HA
Penetrates the upper layers to deliver hydration where skin texture is formed.
Low Weight HA
Reaches deeper skin layers for long-lasting hydration that builds over time.
The Damp Skin Method
Morning Evening
1
Cleanse & Leave Damp
After cleansing, leave your skin slightly damp. HA works best when it has water to bind to.
2
Apply to Wet Skin
Dispense 3-4 drops onto fingertips and press into damp face and neck. Don't let skin dry first!
3
Seal with Moisturizer
Immediately follow with moisturizer to lock in the hydration. This prevents HA from drawing moisture from your skin.
Feel & Texture
Weightless Hydration
Our water-gel formula glides on effortlessly with zero stickiness. It absorbs in seconds, leaving skin perfectly prepped for the rest of your routine. Layers beautifully under makeup without pilling or balling.
- Instantly absorbing water-gel texture
- Zero stickiness or residue

The Science
Multi-Weight Hyaluronic Acid Technology
Why different molecular weights work in concert
High-Weight HA (800-2000 kDa)
Too large to penetrate, these molecules sit on skin's surface as a humectant, preventing transepidermal water loss (TEWL). Creates immediate plumping effect and visible smoothing.
Medium-Weight HA (300-800 kDa)
Penetrates the upper epidermis where visible texture is formed. Delivers hydration exactly where it's needed most for fine line improvement and smoothness.
Low-Weight HA (<300 kDa)
Smallest molecules penetrate deeper to the dermis for long-lasting hydration that builds over time. Supports skin elasticity and resilience from within.
Board-Certified Dermatologist
Dr. Elena Rodriguez, MD
"Hyaluronic acid is one of the most universally safe and effective skincare ingredients. The key to success is applying it to damp skin—this is non-negotiable. LUMIÈRE's multi-weight formula is sophisticated because it targets hydration at multiple layers simultaneously. I recommend this to virtually all my patients, regardless of age or skin type, as the foundation of their skincare."
Dr. Rodriguez has published research on humectant efficacy and barrier function restoration in dermatology journals.
Where HA Fits in Your Routine
Morning Routine
1
Gentle Gel Cleanser
Remove overnight oils. Leave skin slightly damp for HA application.
2
Hyaluronic Acid Serum ★
Apply 3-4 drops to still-damp skin. This is THE most important step—apply to wet skin!
3
Vitamin C (optional)
HA is stable with all actives. Apply after HA has absorbed slightly.
4
Daily Moisturizer (Essential!)
MUST follow HA with moisturizer to lock in hydration. This step is not optional.
5
Mineral Sunscreen SPF 50+
Seal everything in. Wait 1 minute after moisturizer before SPF.
Evening Routine
1
Double Cleanse
Oil cleanser, then Gentle Gel Cleanser. Leave slightly damp.
2
Hyaluronic Acid Serum ★
Apply to damp skin. Can use 2x daily for maximum hydration benefit.
3
Optional Treatments
Retinol or Niacinamide work beautifully with HA. HA actually enhances their efficacy.
4
Rich Moisturizer or Barrier Cream
Lock in HA. Use Ceramide Barrier Cream at night for maximum hydration and repair.
5
Optional: Eye Cream
Eye area also benefits from HA. Apply dedicated eye cream for targeted care.
Critical Rule: Always apply HA to DAMP skin and follow immediately with a moisturizer. Applying to dry skin or skipping moisturizer can actually draw moisture FROM your skin, causing dryness instead of hydration.
HA for Your Skin Type
Oily Skin
★★★★★Perfect! HA provides hydration without adding oil. Even oily skin needs water-based hydration. The lightweight water-gel won't clog pores or feel heavy.
Tips: Use daily 2x if desired. Follow with lightweight moisturizer. The more hydrated your skin, the less oil it produces. HA actually helps balance oily skin.
Dry Skin
★★★★★Essential for dry skin. This is the one product that will transform chronic dryness. Use 2x daily and layer with rich moisturizer for maximum benefit.
Tips: Apply to damp skin every morning and night. Always follow with moisturizer or Ceramide Barrier Cream. Layer Hyaluronic + Moisturizer + Barrier Cream at night for intensive hydration.
Combination
★★★★★Ideal for combination skin. Provides hydration to dry zones while the lightweight formula won't overwhelm oily areas. Perfect balance.
Tips: Use 2x daily. Apply more to dry areas, lighter to oily zones. Pair with lightweight moisturizer on oily areas, richer cream on dry areas.
Sensitive Skin
★★★★★One of the safest actives available. HA is gentle and soothing. Won't cause irritation. Actually helps calm reactive skin by strengthening barrier.
Tips: Use daily 1-2x. Gentle enough for even the most reactive skin. Use with all your other treatments—HA pairs beautifully with everything including retinol and actives.
Mature Skin
★★★★★Essential for mature skin. The multi-weight formula targets hydration at all levels—deep hydration supports elasticity and reduces fine lines from dehydration.
Tips: Use 2x daily. Layer with Vitamin C in AM for antioxidant + hydration combo. Use with Retinol in PM. HA + Retinol is a gold standard anti-aging pairing.
Acne-Prone
★★★★★Safe for acne-prone skin. Won't clog pores. Hydration actually supports healing and can reduce excess oil that causes breakouts. Pairs well with acne treatments.
Tips: Use daily. HA supports skin healing. Safe to combine with salicylic acid, niacinamide, and other acne treatments. Hydrated skin heals faster.
