MESACOSA Organic Maehwasoo Serum

A concentrated botanical anti-ageing serum for smoother, nourished and more resilient skin.

The intensive treatment step of the Maehwasoo ritual, created specifically for dry and mature skin and areas where fine lines are more likely to appear.

At the heart of the formula is 69.53% organic Damask Rose Flower Water combined with 2% Prunus Mume Flower Water, ginseng and Korean Angelica. A luxurious complex of argan, rosehip, macadamia and baobab oils replenishes essential lipids, while hydrolyzed hyaluronic acid helps maintain moisture and skin plumpness.

Astaxanthin and vitamin E add powerful antioxidant support, creating a concentrated botanical treatment focused on maintaining smoother, supple and healthy-looking skin as it ages.

Made with 100% natural-origin ingredients, with 85% of the total ingredients sourced from organic farming, and COSMOS ORGANIC certified by Ecocert Greenlife.

WHY WE LOVE IT

This is where the Maehwasoo routine becomes particularly interesting for mature skin.

Instead of building an anti-ageing serum around aggressive exfoliation or high-strength synthetic actives, MESACOSA takes a different approach: hydration, antioxidant protection, botanical nourishment and support for the skin's natural resilience.

The formula combines traditional Korean botanicals such as ginseng and Korean Angelica with Prunus mume, rose water and nutrient-rich plant oils. Astaxanthin adds another powerful antioxidant component to help protect skin against oxidative stress associated with visible skin ageing.

MESACOSA's patented natural manufacturing method is designed to preserve the beneficial properties of the Prunus mume extract and botanical ingredients throughout production.

Dry and mature skin
Fine lines and loss of elasticity
Skin that feels less supple or resilient
Dehydrated, dull or tired-looking skin
Skin needing additional nourishment and antioxidant protection
Anyone looking for a natural-origin alternative to conventional anti-ageing serums
