— The promise

We don't sell glow.
We sell skin that holds water.

Hydration isn't a finishing step — it's the foundation. Our gel layers three molecular weights of HA so it works at the surface, in the middle, and at the deepest layers your skin can metabolise.

Made in European Union. Held to EU Regulation 1223/2009. Free of fragrance, alcohol and other barrier irritants — your skin gets to breathe.

Four things hydration does. Properly.

— What you'll notice
· 01
30-minute plump

Three HA molecular weights work the surface immediately. Visible bounce within 30 minutes of applying.

· 02
24-hour seal

Polyglutamic acid forms a breathable film that holds moisture in for up to 24 hours — even in dry climates.

· 03
Barrier-friendly

Squalane, beta-glucan and panthenol calm and reinforce. No fragrance, no alcohol, no essential oils.

· 04
Layers with everything

Gel-cream texture sits clean under SPF, makeup, retinol, vitamin C — anything you put on top.

— The ritual

Three steps. Twice a day.

01
AM & PM
Cleanse

Start with damp, gently cleansed skin. Don't dry it completely — HA grabs the water you leave behind.

Pair with: Gentle Cream Cleanser
02
AM & PM
2–3 pumps, press in

Massage gently across face, neck and décolletage. Let it absorb 60 seconds before the next step.

Use morning and evening
03
AM & PM
Seal it in

AM: SPF 50 on top. PM: a sleep cream or face oil to lock the hydration in overnight.

Pair with: Sleep Cream + SPF
— The math

Half the markup.
Not half the formula.

Luxury hydrating gels typically mark up wholesale 8–12×. We mark up 2×, sell direct, and put the difference back into actives — more HA, less packaging tax.

"Hydrates without making my skin feel slippery."

I used to layer two essences and a serum just to feel hydrated. Now it's one gel and I'm done. The texture is unreal.

"Three pumps. Done."

Travelled to Madrid in summer. My skin didn't crash. That's all I needed to know — this is the new permanent.

"Sensitive skin finally tolerates a gel."

No sting, no fragrance, no tightness after. The polyglutamic acid is the upgrade I didn't know I needed.

— Questions

Honest answers.

Still curious? Email hello@erebelle.eu and a human writes back within a day.

Should I apply on dry or damp skin? +

Damp. HA is a humectant — it grabs water molecules. On dry skin in dry climates, it can pull from your own dermis. Mist, splash, or apply right after cleansing.

Should I apply on dry or damp skin? +

Damp. HA is a humectant — it grabs water molecules. On bone-dry skin in dry climates, it can pull from your own dermis. Mist, splash, or apply right after cleansing.

How does this differ from a moisturiser? +

This is a humectant-first gel — it pulls and binds water. A moisturiser seals it in. Use this BEFORE moisturiser, not instead of it.

Can I use it with retinol or acids? +

Yes. Layer it under or buffer on top. Polyglutamic acid is non-reactive and barrier-supporting — it actually softens the sting of strong actives.

Will it pill under SPF or makeup? +

Wait 60 seconds before the next layer. The gel finishes matte-soft and accepts everything from chemical SPF to silicone primer.

Is it safe during pregnancy? +

All actives in this formula are considered pregnancy-safe under current EU dermatological guidance. We always recommend confirming with your healthcare provider.

Why is it so much cheaper than luxury HA serums? +

We sell direct and reinvest the saved markup into actives.
