SKINFOOD - Asparagus Glutathione Spicule Serum 50ml

SKINFOOD Asparagus Glutathione Spicule Serum coats glutathione onto micro-spicules — a delivery system that carries the brightener deeper than a standard serum, backed by vitamin C and asparagus extract.

What spicules are

Microscopic needle-like particles, traditionally derived from freshwater sponges, that create micro-channels as you massage the serum in. The point is delivery: actives coated onto spicules reach where surface-applied ones don’t.

Uniform spicules, coated glutathione

This formula uses highly purified spicules of uniform shape — the detail that matters, because irregular spicules are what make cheap versions feel harsh. The glutathione rides in on the spicule itself.

Vitamin C and asparagus

Vitamin C doubles down on brightening and supports the look of elasticity; antioxidant-rich asparagus extract is SKINFOOD’s signature food-ingredient touch. Skin irritation testing is completed.

Expect the tingle

Honest framing: spicule products tingle or prickle for a while after application — that’s the format working, not an allergic reaction. It typically settles within hours and fades with repeated use. This is not the product to start a sensitive-skin journey with.

Night product, sunscreen mornings

Use it in the evening, keep the routine around it gentle, and be diligent with SPF — freshly stimulated skin deserves protection.

How to use

In the evening after toner, apply to face avoiding the eye and lip areas, and massage gently until absorbed. A mild prickling is normal. Skip acids and retinoids that night, follow with moisturizer, and wear sunscreen the next morning. Start with two to three nights a week.

Frequently asked questions

Is the prickling sensation safe?

It’s the expected feel of spicules creating micro-channels. If you get lasting redness or stinging well beyond the first hours, scale back frequency.

Can sensitive skin use it?

Cautiously at most — patch test first and start once a week. Reactive skin may be happier with the spicule-free ampoule.

Can I combine it with retinol or acids?

Not on the same night — alternate. Stacking stimulation is how barriers get damaged.

How often should I use it?

Two to three nights a week is plenty; nightly use suits only resilient skin.

When will I see results?

An early glow within weeks; meaningful tone and firmness change over eight to twelve weeks with sunscreen.
