How to use NAD for skin care protection from sun damage

NAD is often called the “cellular battery” because it powers hundreds of processes in your body, including DNA repair and inflammation control.

We all know sunscreen is essential, but the health of your skin also depends on what’s happening at the cellular level.

UV exposure creates free radicals that damage collagen, accelerate ageing, and deplete your skin’s natural defences. Over time, this can lead to wrinkles, dark spots, and even changes in DNA.

This is where NAD, short for nicotinamide adenine dinucleotide, comes in. NAD is a molecule found in every cell of your body, playing a vital role in energy production and cellular repair.

What is NAD, and why is it important for skin health?

As we age, NAD levels decline, making it harder for cells to recover from oxidative stress and UV damage. Restoring NAD can help your skin:

Repair damaged cells faster
Produce healthy collagen
Defend itself against environmental stress
Maintain youthful resilience

How NAD helps protect cells from sun damage

1. DNA repair

UV radiation damages DNA, leading to premature ageing and mutations. NAD is essential for activating enzymes (sirtuins and PARPs) that repair DNA and protect cells.

2. Reducing oxidative stress

NAD helps neutralise free radicals that break down collagen and elastin, keeping skin stronger and smoother.

3. Supporting cellular renewal

By boosting energy in skin cells, NAD helps maintain healthy turnover, so damaged cells are replaced more efficiently.

4. Improving barrier function

Healthy NAD levels support lipid production and barrier repair, which helps prevent moisture loss and further damage from pollutants and UV rays.

How to replenish NAD for healthier skin

While NAD naturally declines with age, you can support your levels through diet, lifestyle, and supplementation.

Eat NAD boosting foods

Include vitamin B3-rich foods such as salmon, turkey, mushrooms, and green vegetables.

Stay active

Exercise has been shown to help maintain NAD production.

Prioritise sleep

Cellular repair happens at night—quality sleep is essential for healthy skin.

Supplement wisely

Rejuvenated’s Regenerate contains NMN (a direct NAD precursor) and powerful antioxidants like resveratrol and fisetin to protect your cells and promote healthy ageing. Regenerate is expertly formulated to replenish NAD with NMN, activate sirtuins for DNA repair, defend against oxidative stress and support collagen and elastin production.

When combined with a good skincare routine and daily sun protection, Regenerate can help you keep your skin looking youthful and vibrant, no matter your age.
