The The Serum Duo by Leahlani combines Happy Hour and Siren in two generous 15-ml sizes - two oil serums that complement each other beautifully. Together, they support calmer, more balanced-looking skin and a fresh, evenly radiant complexion.
- Happy Hour Balancing Serum 15 ml is the gentle, balancing side of the duo. Chardonnay grapeseed oil, rosehip, jojoba, green and white tea, calendula, chamomile, and Blue Tansy support the skin barrier and help calm stressed, sensitive-looking skin and reduce the appearance of redness.
- Siren Brightening Serum 15 ml then, or in rotation, adds more radiance. Jojoba, sea buckthorn, spirulina, and a multifaceted botanical complex support a fresher, more even-looking complexion with a natural glow.
Both serums can be used morning or evening. This allows you to adapt your routine flexibly: Happy Hour when skin needs calm and lipid care - Siren when more freshness and glow are desired.
- Set: two Leahlani oil serums in 15-ml travel sizes

FAQ
What is the idea behind The Serum Duo?
Happy Hour and Siren complement each other in their skincare focuses. Happy Hour brings calm and balance to your routine, while Siren supports radiance and freshness. Together, the duo aims to promote a balanced, even, and vibrant-looking complexion.
Do I have to use both serums at the same time?
No. You can alternate the serums according to your skin's current needs or use one in the morning and one in the evening. The set is intentionally designed to be flexible.
When should I use Happy Hour?
Happy Hour is a good choice when skin feels sensitive, stressed, or unbalanced. The lightweight plant oil blend supports the skin barrier and a calmer skin feel.
When should I use Siren?
Siren is ideal when the complexion looks dull or tired and more freshness and radiance are desired. Sea buckthorn, spirulina, and antioxidant botanicals support a lively, glowing appearance.
Are Happy Hour and Siren traditional serums?
Both are water-free oil serums. Ideally, apply them to slightly damp skin so the small amount can be distributed particularly evenly.
How do the scents differ?
Happy Hour is soft, floral, and herbal, with lavender, chamomile, and rose geranium. Siren smells noticeably livelier and sunnier, with orange, grapefruit, ylang ylang, neroli, and other aromatic botanicals.
Are 15 ml enough to try them?
Yes. Since only about half a pump to one pump is needed per application, the 15-ml sizes provide many applications while also being excellent for travel.
