The Ultimate Protection & Restoration

Learn about the difference:

As we age, declining NAD+ levels reduce the skin’s ability to retain moisture and repair damage. With a thinner outer layer and a tendency for sagging, Asian skin is more prone to dehydration and loss of elasticity, leading to fine lines and a lack of firmness.

Nicotinamide Mononucleotide – (NMN)

The ultimate hydration & anti-ageing booster.

How NMN restores your skin:

  • Deeply Hydrates
  • Prevents collagen breakdown
  • Reduces visible signs of aging
  • Shields against oxidative stress
The ultimate power duo—NMN and Resveratrol work synergistically at a cellular level to supercharge skin renewal.

Every day, your skin faces internal and external stressors that contribute to dehydration, sagging, dullness, and premature aging.

Skin that speaks for Itself.

After hitting my 40s, I noticed my skin losing its bounce and wrinkles forming—especially around my eyes. I’ve tried other collagen before, but this one? Game changer.

In just 3 weeks, my skin feels firmer, more elastic, and so much more hydrated—Sibei worth it!

Wei Xuan Ng (Age 33)

My skin feels plumper, looks brighter, and my melanin spots have faded. I didn't even realize how dull my skin was before—now, I’m worried people will start asking for my IC.

This is the only thing that helped my sagging skin. This is like a facelift in a bottle!

Vanessa Koh (Age 45)

I used to think aging skin was just something I had to accept, but after taking Collagen Diamond Pro, I feel like I’ve hit the reset button.

Mei Ting Soh (Age 43)

My biggest struggle was uneven skin tone and melasma from years of sun exposure. No matter how much vitamin C serum I used, the dark spots barely budged. But after just four weeks of Collagen Diamond Pro, my pigmentation has faded by at least 50%.

Collagen Diamond Pro works best when it becomes a part of your daily wellness ritual. For the first 30 days, we recommend taking 2 sachets daily — one in the morning when you rise and one at night before bed. This routine aligns with your body’s natural rhythm, enhancing absorption and providing your skin with 24/7 support from within.

With consistent use, over 90% of our customers report visible improvements — including smoother skin texture, deeper hydration, enhanced firmness, and a healthy, radiant glow — within just a few weeks. Many start noticing changes as early as day 6.

After the first month, you can continue with 1 sachet a day, and eventually transition to 1 sachet every alternate day to maintain your glow long-term.

We believe in the power of our products and want you to feel confident trying them. That’s why we offer a one-time 30-day risk-free guarantee for first-time customers.

If you're not completely satisfied, you can return the product — even if you've already tried some — within 30 days of purchase for a full refund.

This guarantee is our way of showing how much we stand behind our formula and giving you the peace of mind to experience the benefits for yourself, worry-free. Kindly note: this applies only to your first purchase and is limited to one-time use per customer.
