Drunk Elephant Amino Rain Glasswater Serum — 30 ml lightweight hydrating serum with poly amino acid & multi-weight hyaluronic acid

Drunk Elephant Amino Rain Glasswater Serum is an ultra-hydrating facial serum that combines 1% fermented poly amino acid and four types of hyaluronic acid to visibly boost luminosity, plump texture, and soothe skin for a glass-like finish.

This lightweight 30 ml / 1 fl oz serum uses a targeted hydration complex designed to restore surface moisture, support elasticity, and give skin an immediate dewy sheen without heavy silicones or fragrances. Formulated to play well with other treatments, Amino Rain is free of the brand's Suspicious 6—no essential oils, silicones, drying alcohols, chemical sunscreens, fragrance/dyes, or SLS—so it layers easily under makeup and alongside active serums.

How does Amino Rain hydrate and improve skin feel?

The formula combines 1% fermented poly amino acid (polyglutamic acid) with four molecular weights of hyaluronic acid to lock in moisture at several skin depths. This multi-weight approach helps skin look firmer and softer while a supportive water complex aids barrier recovery.

• 1% fermented poly amino acid for extended surface hydration
• Four hyaluronic acid fractions to plump multiple layers
• Hiya Super Hydration Water Complex to enhance moisture retention
• Fast-absorbing, non-greasy texture suitable under makeup

Can I use it with other serums, treatments, or makeup?

Amino Rain is formulated to layer—shake before use, apply one pump to clean, dry skin, then follow with your preferred serums, treatments, or moisturizer. Its light, water-like finish creates a smooth canvas for foundation or tinted products without pilling.

• Compatible with vitamin C, retinoids, and other Drunk Elephant serums
• Works as a pre-makeup base for a natural glow
• Non-comedogenic and fast-absorbing for quick layering
• Daily use recommended; one pump provides efficient coverage

What key actives are in this serum and what do they do?

The standout actives are fermented poly amino acid (a high-performing humectant) and 0.5% dipalmitoyl hydroxyproline, both chosen to improve hydration and visible firmness. Together with hyaluronic acids and the brand’s hydration complex, they focus on resilience and surface radiance rather than temporary smoothing from silicones.

• Fermented poly amino acid: sustained surface hydration and sheen
• Dipalmitoyl hydroxyproline (0.5%): supports visible firmness and texture
• Multi-weight hyaluronic acids: short- and long-term plumping
• Free of the Suspicious 6 to reduce irritation risk for sensitive skin

Who is this for? Drunk Elephant Amino Rain Glasswater Serum is suited to anyone seeking visible hydration, a luminous, glassy finish, and a lightweight base that layers with other actives. It's a practical option for combination, dehydrated, normal, and sensitive skin types who want a non-greasy, fragrance-free boost in moisture and radiance. If you prefer products without essential oils or silicones and want a serum that enhances makeup application while supporting barrier function, Amino Rain is a targeted pick.
