Our Ultimate Serum is a powerhouse product, perfect for the modern man seeking to maintain a youthful, healthy complexion with minimal effort and maximum results. Key Benefits:

Who this is for

All skin types. Particularly effective for men dealing with dehydration, dullness, fine lines, or skin that looks tired regardless of sleep.

Who this may not suit

The Ultimate Serum combines Seaweed Collagen, Hyaluronic Acid, and Kakadu Plum Vitamin C in a water-based formula designed to absorb quickly and work on multiple concerns simultaneously. That combination is highly effective for most men. There are a few situations where it is worth pausing before you start.

If your skin is currently dealing with active, inflamed breakouts, the Hyaluronic Acid will still hydrate and the Vitamin C will still brighten, but the inflammation may prevent the deeper active work from landing properly. In this case, spend two to three weeks on just the cleanser and moisturiser to calm the skin first. A stable surface absorbs a serum significantly better than an inflamed one.

If you are already using a prescription Vitamin C, a clinical retinoid, or a dermatologist-prescribed treatment, be deliberate about sequencing rather than stacking. Kakadu Plum delivers more bioavailable Vitamin C per gram than most synthetic formulations, but combining high-potency natural Vitamin C with prescription Vitamin C compounds can push the skin beyond what it can comfortably process. If in doubt, use one or the other and speak to your dermatologist.

The Seaweed Collagen in this serum supports your skin's collagen and elastin matrix over time. This is not a one-application fix. Most men notice improved hydration and a smoother surface within three to four weeks. The visible reduction in fine lines that comes from consistent collagen support takes six to eight weeks. If you are expecting a dramatic change in the first week, this is not the right product for that expectation. No topical serum is.

How to use

Apply after cleansing to slightly damp skin, before moisturiser. Add a small amount to both index fingers. Starting at your nose, smooth outward over your cheeks and across your forehead. Allow two minutes to absorb before applying Daily Moisturiser. Use morning and evening for best results.

What to expect

Skin looks and feels noticeably more hydrated from the first use. Fine lines appear shallower within minutes of application as the Hyaluronic Acid draws moisture to the surface. After four weeks of consistent twice-daily use, skin tone becomes more even and the surface texture improves as the Vitamin C and Vegetable Collagen produce cumulative brightening and firming effects.

Love this product. I will be getting it again. I did buy products for my son but decided to try this for myself. Really made a difference to the lines under my eyes. Leaves my face feeling smooth. Love that it feels more on the watery side then oily side. Highly recommend.

Gregory V. · 5/5 · 2025-04-22

This product goes a long way. I was skeptical in the beginning but then noticed the redness disappearing over time. I use it after shaving, allowing time to set in before adding a moisturizer . I will order again. I love the stylish bottle and the pump which releases the right amount of product.

Will M. · 5/5 · 2025-12-28

Just put in my 3rd order. I use it every morning and I get regular comments about how great my skin looks and how I do not look my age. I’m 71.

Frequently asked questions

What is the difference between the serum and the elixir?

The Ultimate Serum is water-based, lighter, and designed for morning use. It focuses on hydration and brightening with Hyaluronic Acid and Vitamin C. The Anti-Ageing Elixir is oil-based, richer, and designed for evening use. It focuses on collagen repair and deep nourishment.

Can I use both the serum and elixir?

Yes. Use the serum in the morning and the elixir in the evening. They complement each other and provide 24-hour coverage of hydration, brightening, and repair.

Is plant-based collagen as effective as animal collagen?

Our vegetable collagen derived from seaweed helps support your skin's own collagen production rather than adding external collagen. It works by providing the building blocks your skin needs to repair and strengthen its natural collagen and elastin framework.
