Product Description

Our hydration serum for all skin types. Soothes, smooths and calms skin while delivering deep hydration.

Delivers deep hydration with a skin-friendly pH of 5
Contains dual Helichrysum extracts for powerful soothing benefits
Provides immediate and sustained moisture with multiple humectants
Versatile enough for use around eyes and lips

Equinox, formerly known as Everlasting, is a botanical gel serum formulated to deliver comprehensive hydration while addressing multiple skin concerns. This lightweight, fast-absorbing formula is suitable for all skin types, including sensitive complexions.

Helichrysum-rich formula for skin resilience

The serum features Helichrysum as a central botanical element, incorporating both Helichrysum italicum flower water and Helichrysum stoechas extract to maximize soothing and anti-inflammatory benefits. This dual Helichrysum approach works alongside Alpine-sourced Edelweiss extract, which helps reinforce barrier function while providing protection against environmental factors.

Deep Hydration Strategy

Equinox employs a multi-layered hydration strategy combining botanical waters from chamomile and rose with effective humectants including Sodium PCA, glycerin, and trehalose. This approach ensures immediate moisture delivery and sustained hydration. The addition of panthenol (vitamin B5) and allantoin enhances the formula's soothing capabilities while supporting cellular renewal. Green tea leaf extract and spirulina provide antioxidant benefits and support skin resilience.

The serum's blue gel texture melts effortlessly into the skin, providing an immediate cooling sensation that feels refreshing for irritated skin. Equinox delivers immediately noticeable results, addressing fine lines, reducing redness, and creating a smooth, hydrated canvas for subsequent products or makeup. The versatile formula can be used around the delicate eye and lip areas, simplifying multi-step routines.

Using this Gel

Experience it

EQUINOX is a distinctive blue gel texture that feels instantly cooling and refreshing as it glides over the skin, delivering an immediate surge of hydration that absorbs within seconds. The natural scent profile is a harmonious blend of fresh grassy notes with delicate floral undertones. Upon absorption, the skin feels noticeably plumper with a dewy finish that looks naturally radiant, creating the perfect canvas for makeup or an ideal hydration layer under facial oils.

How to Use it

Apply EQUINOX to freshly cleansed, slightly damp skin both morning and evening, dispensing one to two pumps onto fingertips and pressing gently into the face, neck, and décolletage. For morning use, layer EQUINOX beneath your moisturizer and sunscreen to create a protective hydration barrier, or mix a pump with your foundation for added dewiness. In your evening routine, EQUINOX serves as the perfect companion to active treatments—apply before retinol products to buffer potential irritation, or use after acid exfoliants to calm and rehydrate skin; for an intensive overnight treatment, apply EQUINOX followed by facial oil to create a moisture-locking sleep mask.

Why You Need it

Our gel serum works at multiple skin levels to actually improve barrier function while providing immediate relief to stressed complexions. The versatile formula serves as both a preventative and corrective treatment—defending against environmental aggressors while simultaneously repairing existing damage—making it essential for any skincare regimen regardless of skin concern.

Key Ingredients in EQUINOX Calm + Smooth Hydration Serum

Edelweiss (Leontopodium Alpinum) Extract

This alpine plant survives extreme UV, wind, and cold by producing powerful protective compounds, and your skin benefits from the same chemistry. Rich in leontopodic acids with antioxidant activity that rivals vitamin C. A quiet powerhouse.

Sodium PCA

Your skin naturally produces sodium PCA as part of its moisture-retention system. Supplementing it topically draws water into the outer layers of skin and holds it there, keeping things plump and comfortable all day.

Panthenol (vitamin B5)

Penetrates into skin and converts to pantothenic acid, which your cells use to produce energy and repair themselves. Attracts and holds moisture, reduces redness, and strengthens the skin barrier. One of those ingredients that quietly makes everything better.
