Beautifully defined upper arms are a real eye-catcher. And especially in spring and summer, the upper arms are particularly in focus. With skin689 Firm Skin Upper Arms Emulsion , they are specifically firmed and contoured.

As an expert in effective cosmetic skin tightening & Anti-cellulite cream With its Firm Skin Upper Arms Emulsion, skin689 takes upper arm treatment to a new level. By combining innovative active ingredients, it tackles the two main causes of sagging skin twice – for maximum effectiveness!

CHacoll® This is skin689's proprietary, patented active ingredient, developed through medical research. It promotes the formation of the skin's own collagen fibers, thus strengthening the subcutaneous network. Fat cells are retained, resulting in firmer and tighter skin.

DermCom® It stimulates keratinocytes to secrete growth factors, thereby significantly improving the synthesis of collagen and elastin in the skin and strengthening connective tissue – for firmer, more elastic skin.

CoAxel® CoAXEL™ is the world's first active ingredient with in-vivo proven efficacy in collagen and elastin regeneration. It is a patented combination of caffeine, coenzyme A, and L-carnitine. It stimulates energy metabolism, promotes the breakdown and removal of fatty acids, and reduces tissue fluid retention.

From a dermatological perspective, the observed structural improvement can be summarized as follows:

"A structural, lasting improvement in cellulite! The skin becomes plumper and more elastic, and the skin texture is improved." — Dr. Tatjana Pavicic

Several in-vivo studies have already confirmed the exceptional effectiveness of CHacoll® on skin elasticity and fat volume. A new in-vitro study has now confirmed its dual mechanism of action on collagen fibers and fat cells.

This mechanism of action is perfectly suited for targeted cosmetic tightening of the upper arms.

It synergistically complements the other active ingredients for a deep structural effect that targets the causes of sagging skin.

Valuable ingredients like sweet almond oil leave skin feeling velvety soft. Panthenol and shea butter provide moisture and improve skin elasticity. Simply apply the cream to the affected areas once a day!
