LightStim PhotoSerum Hydration Elixir

LightStim® PhotoSerum

A serum built to amplify LED treatment results, not just moisturize on its own.

This light, silky serum is formulated around SFC (Disodium Succinoyl Farnesylcysteine), a proprietary molecule developed at Princeton University that targets several key cytokines involved in skin inflammation, clinically proven in a 12-week study to outperform niacinamide across nearly every measure of skin improvement. Sodium hyaluronate instantly boosts moisture levels, ergothioneine provides potent antioxidant protection against environmental damage, and glycerin and propanediol add long-lasting hydration and a smooth, silky finish. Clinically proven, dermatologist-recommended, hypoallergenic, and safe for all skin types, including sensitive skin.

Why it works: LED light therapy works by stimulating the skin's cells to produce more of what keeps it firm and hydrated, but that process still needs the right ingredients on hand to work with. SFC is formulated to target the inflammatory cytokines that drive wrinkles, redness, and uneven texture at the source, rather than just sitting on top of the skin as a moisturizer would, which is why it's designed to be used alongside a LightStim treatment: the light triggers the skin's renewal process, and the serum supplies what that process needs to work with.

How to use it:

1. Apply liberally to clean, dry skin.
2. Massage into the face, neck, and décolletage, avoiding the eye area.
3. Use twice daily, morning and night.
4. For best results, use immediately following a LightStim LED treatment.

The worth//vitality promise

We chose this serum because it's built to work with LED therapy rather than as a separate step, the same inflammation-targeting molecule that's been clinically shown to outperform a common serum ingredient like niacinamide, developed through actual university research rather than a proprietary blend with no real backing. That combination of clinical data and purpose-built pairing with the devices we carry is what earns it a place in the lineup.
