Siren Brightening Serum 30 ml

The Siren Brightening Serum by Leahlani was developed for skin that appears tired, dull, or uneven and needs more clarity, evenness, and radiance. Lightweight jojoba oil meets highly concentrated sea buckthorn CO₂ extract, spirulina, vitamin E, and an exceptionally versatile complex of citrus, floral, and botanical oils.

• Product type: lightweight, anhydrous brightening and glow serum
• Skin types: ideal for combination, oilier, dull, and blemish-prone skin
• Brightening: helps support a clearer, fresher, and more even-looking complexion
• For dull skin: makes tired, lackluster skin appear more vibrant and radiant
• Evenness: antioxidant botanicals help visibly balance the appearance of irregularities in the complexion
• Skin feel: lightweight, silky, and smooth, without feeling heavy
• Key ingredients: sea buckthorn CO₂ extract, spirulina, jojoba oil, vitamin E, and selected botanical oils
• Quality: vegan, cruelty-free, made with organic botanical ingredients and without synthetic colorants or fragrances

At the heart of the formula is sea buckthorn, rich in carotenoids, tocopherols, and antioxidant plant compounds. Together with spirulina and the botanical oil complex, it helps visibly balance unevenness in the complexion, make dull areas appear fresher, and promote the skin's natural radiance. With regular use, the complexion appears more vibrant, clear, and even.

What makes Siren unmistakable is its botanical complex of orange, grapefruit, mandarin, neroli, ylang ylang, palmarosa, various types of chamomile, rose, frankincense, and other plant essences. It shapes both the skincare character and the serum's sunny scent. The result is not a neutral active serum, but a colorful Leahlani ritual full of energy and Aloha Glow.

Key ingredients

• Sea buckthorn CO₂ extract is Siren's central brightening ingredient and is rich in intensely colored carotenoids, tocopherols, and valuable fatty acids. Its antioxidant plant compounds help protect the skin from oxidative stress and support a fresher, more even, and more radiant-looking complexion. At the same time, its lipids help keep the skin supple.
• Jojoba oil forms the lightweight base of the serum. Its liquid wax esters resemble the skin's natural lipids in structure, spread very evenly, and leave a silky, barely greasy skin feel. This makes Siren appealing for combination and oilier skin that benefits from lipid care but does not want a heavy oil texture.
• Spirulina provides proteins, amino acids, minerals, and antioxidant pigments such as phycocyanin. This microalga supports a vital, balanced complexion and complements the serum's glow focus with nutrient-rich botanical care. Together with sea buckthorn, it contributes to Leahlani's characteristically vibrant formulation.
• Orange, grapefruit, mandarin, and tangerine bring antioxidant plant compounds and Siren's bright citrus side to the formula. They give the serum its sunny scent and, together with the other botanicals, support a fresh, vibrant complexion.
• Ylang ylang, palmarosa, and geranium complement the citrus oils with softer, floral plant essences. They give Siren greater aromatic depth and contribute to a cared-for, balanced skin feel without changing the lightweight base texture.
• Chamomile, frankincense, rose, and carrot seed oil round out the complex botanical blend with antioxidant and skin-nourishing components. Carrot seed oil adds additional carotenoids, while the various types of chamomile and rose give the serum its softer floral side. Vitamin E also supports antioxidant protection and the stability of the botanical oils.

How to use

• Shake gently before use.
• ½ to 1 pump into the palm of your hand and massage into cleansed, still slightly damp skin on the face and neck.
• Use morning and/or evening.
• On slightly damp skin, the small amount spreads especially evenly. For example, the Citrus + Citrine Toning Mist is ideal to use beforehand.
• In the morning, follow with a suitable sunscreen.

FAQ

What does brightening mean for Siren?
Here, brightening does not mean lightening the skin's natural color. Siren was developed to make dull, tired, and uneven-looking skin appear fresher, clearer, and more even while supporting its natural radiance. Leahlani itself explicitly positions the serum for “radiant, even-toned skin.”

What skin types is Siren suitable for?
Siren is particularly suited to combination, oilier, dull, and blemish-prone skin. It is also suitable whenever the complexion looks unsettled, lackluster, or less vibrant and greater evenness and radiance are desired.

Does Siren help with uneven skin tone?
Yes, this is one of the serum's main focuses. Sea buckthorn, spirulina, and the antioxidant botanical complex support a more even and clearer-looking complexion and help visibly soften differences in color and texture. Leahlani explicitly names improved evenness as a core benefit of Siren.

Is Siren a vitamin C serum?
No, not in the traditional sense. The INCI does not contain a separately declared vitamin C active such as ascorbic acid or a vitamin C derivative. The brightening focus comes from the combination of sea buckthorn, spirulina, vitamin E, and the complex botanical antioxidant blend.

Is Siren also suitable for oily skin?
Yes. Jojoba has a lightweight, silky texture and is often well tolerated by oilier skin. For oily skin, half a pump is usually sufficient.

Can Siren be used for blemishes?
Yes. Leahlani also recommends Siren for blemish-prone skin. The serum supports a balanced, even-looking complexion, but it is not a product for treating acne.

What distinguishes Siren from Happy Hour?
Happy Hour focuses on sensitive, stressed skin, soothing, and balance. Siren focuses more strongly on brightening, evenness, freshness, and radiance.

What does Siren smell like?
Lively, sunny, and botanical. Orange, grapefruit, and mandarin meet ylang ylang, palmarosa, geranium, chamomile, neroli, and rose - a multifaceted scent that perfectly suits the serum's radiant character.
