Deep Hydration Serum — Multi-Weight Hyaluronic Acid (4 Types), 1 fl oz

When used twice daily as directed (2-3 drops per application), one 1 fl oz (30 ml) bottle lasts 60-90 days. The concentrated
formula means a little goes a long way.

Yes! This serum is gentle and complements active ingredients perfectly. Apply the Deep Hydration Serum first (on damp skin), wait 60 seconds, then apply your retinol or vitamin C. The hyaluronic acid actually helps other actives penetrate better while protecting your skin barrier.

No. Our formula is non-comedogenic and oil-free. Hyaluronic acid is a humectant (water-binding molecule), not an oil — so it won’t clog pores. In fact, many customers with acne-prone skin find it helps balance their skin without adding excess oil.

Absolutely. Our formula is specifically developed for sensitive skin and excludes common irritants (parabens, sulfates, synthetic fragrances, harsh alcohols). The botanical blend (chamomile, aloe, green tea) actively soothes sensitivity.

However, as with any new product, we recommend patch-testing first if you have extremely reactive skin — apply a small amount to your inner arm and wait 24 hours before using on your face.

Most customers notice immediate improvement in hydration (within the first application). Visible reduction in fine lines typically appears within 2–4 weeks of consistent, twice-daily use.

TIMELINE:
- Day 1: Instant plumpness and hydration
- Week 2: Fine lines begin softening
- Week 4: Significant improvement in texture and firmness
- Week 8+: Continued improvement in overall skin quality

Three key differences:

1. Multi-weight formula: Most drugstore serums use only one molecular weight of HA (usually high molecular weight) which only hydrates the surface. We use 4 different weights to penetrate all skin layers — from surface to deep dermis.
   
2. Concentration: Our clinical-grade concentration is significantly higher than drugstore alternatives, delivering more dramatic results.
   
3. Complementary actives: We’ve added peptides, antioxidants, and soothing botanicals that work synergistically with HA for enhanced anti-aging and barrier-strengthening benefits.

Yes! Despite being intensely hydrating, this serum is oil-free and won’t make your skin greasy. In fact, oily skin is often dehydrated (lacking water, not oil), and proper hydration helps balance oil production.

Apply to damp skin and follow with a lightweight, oil-free moisturizer for best results.

No. This serum is fragrance-free. There’s only a very faint, natural scent from the botanical ingredients (green tea, chamomile, aloe), but it’s barely noticeable and disappears within seconds of application.

We never add synthetic fragrances, which are a common cause of irritation and allergic reactions.

Yes. This serum contains only pregnancy-safe ingredients (no retinoids, no essential oils, no harsh actives). However, we always recommend consulting your healthcare provider before starting any new skincare products during pregnancy or breastfeeding.
