Active ingredients

Niacinamide (Vitamin B3)

A multi-functional active that evens tone and supports skin barrier feel.

Niacinamide (Vitamin B3) is one of the most researched actives in cosmetic science. It is a multi-functional ingredient that supports the feel of a more even, balanced and resilient skin surface, and it is exceptionally well-tolerated across skin types. In SEACRET formulas, Niacinamide appears in the Dual Phase Booster, Rich Hydrating Night Cream, Scrubbing Mask, Moisturizing Day Cream, Rich Nourishing Serum (5th ingredient) and Men's Advanced Recovery Face Cream (3rd ingredient).
Key benefits: Helps the skin look more even in tone and refined in texture | Supports the feel of a comfortable, well-balanced skin barrier | Well-tolerated by every skin type including sensitive and oily

FERMENT 21 Complex | Dunaliella Salina Extract + Yeast Ferment Extract + Maris Sal

SEACRET's patented bio-fermented mineral complex and face-care hero ingredient.

FERMENT 21 (also referenced as Seacret Broth) is SEACRET's proprietary bio-fermented complex that combines Dunaliella salina microalgae with Dead Sea minerals and yeast ferment extract (Registered Patent Ref: 2017143RE170704). The bio-fermentation process produces smaller, more skin-compatible molecules. In-use research on 20 women and ex vivo work with Ashland/Vincience and Stony Brook University documented barrier-supporting and radiance outcomes. FERMENT 21 appears in the Dual Phase Booster, Rich Hydrating Night Cream, Ultra Rich Moisture & Glow Cream, Peptide Eye Cream, Triple Hyaluronic Acid Glow, Milky Essence Mist, Rich Nourishing Serum, Moisturizing Day Cream and Renewal Multi Acid Night Serum.
Key benefits: Supports the feel of a stronger skin barrier with documented Claudin-1 markers | Helps the skin look visibly more luminous and well-hydrated | Patented bio-fermented technology exclusive to SEACRET face care

Blueberry Leaf Extract | Vaccinium Angustifolium Leaf Extract

Polyphenol-rich botanical for antioxidant skin defense.

Blueberry Leaf Extract is a concentrated botanical sourced from wild blueberry leaves, rich in polyphenols and flavonoids that contribute antioxidant properties to cosmetic formulas. In SEACRET Rich Nourishing Serum, the extract complements FERMENT 21 and niacinamide, helping support the look of resilient, well-conditioned skin, particularly for drier and more mature skin types.
Key benefits: Provides antioxidant support against environmental stressors | Works alongside FERMENT 21 in the Rich Nourishing Serum | Suits dry and mature skin needing extra botanical support

Pomegranate Seed Extract

An antioxidant-rich fruit extract for protection against environmental stressors.

Pomegranate Seed Extract and Oil are derived from Punica granatum and are recognized for their punicic acid and polyphenol content. In SEACRET Salt and Botanical Oil Body Scrubs, it contributes antioxidant support alongside the Dead Sea salt base. In Restorative Mineral Body Butter Ocean Mist and Pomegranate variants, it doubles as an antioxidant botanical and a scent-anchor ingredient, and it also appears in Rich Nourishing Serum.
Key benefits: Delivers antioxidant support against environmental skin stressors | Contributes to the look of healthy, well-conditioned skin | Present across body scrubs, body butters and the Rich Nourishing Serum

Rich Nourishing Serum

Softer-looking skin in one week
Rich nourishment for dry and mature skin
FERMENT 21™ + Dead Sea minerals

Available in stock

A Dead Sea nourishing serum for skin that is thirsty and has stopped responding to basic hydration.

This one sits heavier on skin than a typical serum, on purpose.

Press 3 to 4 drops into skin that has stopped drinking up
lighter formulas, and feel it settle in, dense and cushioning,
before it disappears within 60 seconds. Underneath that weight is FERMENT 21, our bio-fermented Dead Sea mineral complex, layered with hyaluronic acid and niacinamide. Skin looks plumper and softer by morning, and the effect holds through the next day. Apply after toner, before your moisturizer, on slightly damp skin.

Product benefits

Richer than a hydrating serum, lighter than a cream

It fills the gap for skin that needs more than a thin HA serum but does not want a heavy oil. The texture absorbs within 60 seconds and layers well under moisturizer.

FERMENT 21™ + niacinamide

Signature FERMENT 21™ (studied with Ashland and Stony Brook University) plus niacinamide at a functional concentration supports both barrier function and a more even look of tone. Niacinamide suits every skin type, including sensitive.

Softer-looking skin within one week

Users consistently report softer-looking skin within 5 to 7 days of twice-daily use, with cumulative effects on fine-line appearance and tone over 4 to 6 weeks. Dry and mature skin often see the fastest response.

Works as a routine anchor

Toner, eye cream, and spot treatments layer around this serum without conflict. A reliable foundation rather than a showy hero product.

Frequently asked questions

How fast will I see results?

Softer-looking skin within the first week. Plumping and smoother-looking fine lines within 4 to 6 weeks. Mature and dry skin typically see faster visible results because the baseline deficit is larger.

Is it right for oily or combination skin?

Less ideal. Oily and combination skin are usually better served by SEACRET Triple Hyaluronic Acid Glow. This serum is richer and best suited to normal-to-dry and mature skin.

Can I layer it under a retinol cream?

Yes. Apply the serum to damp skin first, let it absorb for a minute, then layer your retinol product on top. It can help skin feel more comfortable during the early weeks of a retinol cycle.

Will it pill under makeup?

Not at the recommended dose. Use 3 to 4 drops and wait a minute before applying cream. Pilling usually comes from over-application or rushed layering.

Why is a richer serum better for mature skin?

Mature skin has reduced lipid production and a weaker barrier. A watery serum skims the surface; a richer format delivers both humectant hydration and lipid support. The texture matches the deficit.

Is it safe during pregnancy?

The formula does not contain retinol or other commonly avoided pregnancy ingredients. Always consult your OB before adding any new product during pregnancy.

How long does one bottle last?

With twice-daily use of 3 to 4 drops, a 1 fl oz bottle typically lasts 2 to 3 months.
