Skin under rapid change

needs skincare built for it.

When your body changes quickly, your skin loses firmness, elasticity and bounce faster than ordinary skincare can keep up. ElastiK° is a five-step system made for exactly that.

How to help

skin in rapid change?
1
Your skin went through a change

Rapid weight loss and hormonal shifts reduce fat, collagen, elastin and muscle, the layers that once kept skin taut and structured. Standard single skincare wasn't made for this.

2
The Skin in Evolution™ system supports it

Six products, one routine, formulated around hydration, elasticity, renewal and collagen-supporting ingredients.

3
Skin that feels firmer, more hydrated and resilient

Confidence from the outside in, supported by a skincare system designed for exactly where you are now.

Lost on GLP-1

I lost 126lbs.

Nobody warned me what it would do to my skin.

"I spent a year testing everything on the market. Nothing was formulated for skin going through real transformation. So I ran my own trial based on what worked for me, built the system my community told me they needed, and launched it to the world from Paris in April 2026."

Your questions.

Honest answers.

Still not sure where to start? The 60-second quiz matches the routine to your skin.

Can I use it while on GLP-1 medication?

Yes, the routine was built around skin going through GLP-1 weight loss. ElastiK° products are topical cosmetics applied to the skin. They're not a medicine. If you have any concerns, check with your prescriber or pharmacist.

Is it only for weight loss?

No. It's for any period of rapid change: significant weight loss, perimenopause, menopause, postpartum recovery and natural ageing. These all affect hydration, firmness and elasticity in similar ways.

When will I notice a difference?

In our 6-week pre-launch trial, participants most often noticed hydration first, with firmness reported from around week four. Everyone's skin is different. Consistency matters more than intensity, so use the routine daily.

What order do I use the products in?

Morning: 1 Hydration Continuum Gel, 2 Collagen Architect Serum, 3 LED Mask (morning or evening).

Evening: 4A Regenesis Complex, 4B Evolve Serum on the body, 5 Resilience Matrix Night Cream.

Is it suitable for sensitive skin?

The range is dermatologically tested, vegan and cruelty-free. As with any new skincare, patch test on a small area 24 hours before first use. Full ingredient lists are on each product page.
