FAQ

Products & Routine

Where do I start?
If you're new to FOURTHIRTY, The Mist Duo (face + hair) is the easiest introduction. For the complete skin, scalp and hair system, choose The Full Ritual.

How do I layer the products?
Skin first (Ionic Mist 400 on clean skin), then scalp (Follicle Fuel), then hair (UV Halo Shield). In the sun, always apply your SPF before Solar Gravity.

How long will one product last?
With daily use, the mists last roughly 6–8 weeks. The Follicle Fuel roll-on (10ml) is a concentrated daily treatment.

When will I see results?
Hydration and glow are immediate. Tone and texture refine over 4–8 weeks. Hair density follows the natural hair cycle — give Follicle Fuel at least 8–12 weeks of consistent use.

Skin & Scalp Safety

Are the products suitable for sensitive skin?
Most are formulated to be gentle, but we always recommend a 24-hour patch test on the inner arm before first use. Discontinue if irritation occurs.

Are they tested?
Our formulas use cosmetic-grade actives at considered concentrations. They are cosmetic products, not medicines, and are not intended to diagnose, treat or cure any condition.

Can I use them while pregnant or breastfeeding?
Please consult your doctor before use — particularly for Follicle Fuel, which contains rosemary and spearmint.

Sun & Solar Gravity

Is Solar Gravity a sunscreen?
No. Solar Gravity contains no SPF and offers no protection against UV. Always apply a broad-spectrum sunscreen, avoid peak-hour sun, and never use sunbeds.

Is it a fake tan?
No. It works with your skin's natural response to sun to deepen and even your tan — it is not a wash-off bronzer or DHA self-tan. Body only, not the face.

Where do you ship?

The Origin

The Jordan Valley sits at the lowest point on the surface of the earth. The air is denser here, the light arrives filtered, and the water holds one of the highest mineral concentrations found anywhere on the planet. It is an extreme place — and extremity is exactly what skin responds to.

The Purpose

FourThirty was built on a simple refusal: nothing in the bottle for show. We take the purest forms of Dead Sea minerals and pair them with bio-active ingredients chosen for what they actually do — then we stop. No filler claims, no inflated routines, no fluff. Every formula has to earn its place by results alone.

The Promise

We call it a commitment. You can call it the standard, raised.

−430m below sea level. Above the standard.
