What Others Are Saying
I was skeptical at first, but this cream blew me away. Within two weeks, my skin looked smoother and my fine lines started fading. It feels rich but not greasy, and my skin drinks it up instantly. I wake up looking like I actually slept eight hours!
I’ve tried so many anti-aging creams that claim miracles — this one actually delivers. My skin feels firmer, more hydrated, and my makeup goes on so much better now.
I live in a cold climate and my skin gets super dry in winter. This cream has been a total game changer. It keeps my skin soft all day and gives it a nice glow. Fine lines around my eyes are definitely less noticeable now.
I’ve been using this for a month and can see a big difference in texture and elasticity. My skin feels tighter and more hydrated, and the lines on my forehead are less visible. I’ve spent more on creams that did nothing, this one’s staying in my routine for sure.

What is the major advantage of using this cream?
The major advantage of using a cream in skincare is its ability to provide long-lasting moisture and protection by forming a rich, occlusive layer that seals hydration into the skin and supports barrier repair — making it essential for maintaining smoothness, softness, and resilience.
How does this cream differ from other regular hydration products?
Unlike typical creams that focus only on surface moisture and maintaining smoothness and softness, this GTA™-centered cell repair and anti-wrinkle cream intensifies skin hydration and renewal efficacy, increases skin regeneration, and boosts collagen production. It helps reset accelerated skin aging back to normal aging while visibly improving the appearance of fine lines, wrinkles, and elasticity.
How soon will I see results?
In general, you can see that the skin’s hydration level and elasticity improve quickly after applying this cream. As soon as 2 hours after application, the increase in hydration and elasticity can be measured using Idunn’s Apple Skin Age self-test. Texture and radiance will improve as early as 3–4 weeks. With continued use, results include enhanced tone, firmness, and overall skin vitality.
Does this cream contain harmful ingredients?
Not at all. Our formula is crafted with EWG Green–rated ingredients (low hazard rating of 1–2) and is free from parabens, synthetic fragrances, and other harsh additives.
Can this cream be used with your other products or with my current skincare routine?
Yes! This cream can be used with our other anti-aging products to create an age-targeted skincare module for optimal results. It also layers well under most skincare and makeup products. For best results, use it after cleansing and before your moisturizer or sunscreen.
How should I store this product to avoid color changes, since it contains vitamin C?
This cream can be stored at room temperature. Unlike many other vitamin C serums that turn yellow after a few weeks due to oxidation, this formula remains clear and stable. Its unique stabilized vitamin C complex and oxidation- and light-resistant packaging help maintain its freshness and effectiveness over time.

It didn’t happen overnight, but after about a month, my skin looks more lifted and firm.

I apply it before bed, and my skin still feels moisturized the next afternoon. It’s that long-lasting. My skin has a nice glow now, and I don’t wake up with that tight, dry feeling anymore.
