What helps skin look well-rested, even when life doesn’t slow down? ✨

Over time, pollution, stress, and a fast-paced routine can make it harder for skin to defend itself and maintain a fresh, healthy-looking appearance.

Melatogen Serum is designed for that moment.
A lightweight fluid-gel that helps support skin renewal and improve the look of visible aging signs, while keeping the texture comfortable for daily use.

Powered by melatonin and EpigenCur®, HD’s epigenetic active, it supports the skin’s natural repair rhythm and helps protect against daily oxidative stress 🧬

The result: skin that looks smoother and visibly more rested.
Advanced care, with a lightweight feel 🤍

Real skincare starts with formulas designed to perform and tested to prove it 🤍

That is why our formulas are developed through a science-led approach and supported by efficacy studies, so every benefit we communicate is backed by real evaluation.

This is also the thinking behind EpigenCur®, our exclusive epigenetic active and part of HD’s research-driven vision: innovative skincare designed to support skin through daily stress.

Because at HD, trust comes from how a formula is built — and how its results are proven ✨

At HD, efficacy starts with ingredients that are built with purpose 🧪

Epigencur® is our exclusive epigenetic active, created to help skin respond better to daily external stress.

Its efficacy has been studied in vitro as part of our research in cosmetic epigenetics — because for us, science is not just part of the message, it is part of the formula.

You’ll find Epigencur® in key HD formulas available in the U.S., including Melatogen and Redefiner.

A clearer approach to skincare, built on proven work 🤍

When a result is measured properly, it becomes easier to trust 🧪

That is the role of efficacy studies at HD: to evaluate what a formula does under defined conditions, and make every visible benefit easier to understand.

In the case of HD REDEFINER Serum, an in vitro study showed a 72.1% increase in elastin gene expression (Eln)— a key result behind its firming and lifting-support positioning.

Why this matters:�• It gives scientific context to the formula�• It translates visible claims into measured data�• It strengthens trust in the result

Evidence is part of the formula 🤍

Some formulas target what you see. Others support how skin behaves over time 🧬

That is the logic behind Melatogen.

More than a melatonin-based line, Melatogen is built with an epigenetic skincare approach through Epigencur®, HD’s epigenetic active, designed to support skin exposed to daily oxidative stress.

Melatonin supports the skin’s natural repair rhythm and antioxidant response, while Epigencur® helps reinforce the formula’s approach to visible firmness, elasticity, and skin resilience.

The line is also supported by carnosine and low molecular weight hyaluronic acid, helping improve hydration, skin comfort, and overall skin appearance.

Advanced care, rooted in epigenetics🤍

WOMEN'S DAY SPECIAL

Every woman builds her own path. In her decisions, in how she moves forward, and in how she chooses to take care of herself.

At HD, there are three values that reflect this way of growing and evolving:

Confidence: As Dulce says, it starts within you. In how you feel, how you act, and in the decisions you make every day to keep moving forward.
Effectiveness: For Regina, it's about making every choice count, betting on what really works, and pursuing your goals with determination.
Sensory awareness: Sharon is clear about this: it's also important to stop, connect with yourself, and turn self-care into a moment of well-being.

Three values that speak of consistency, conscious choices, and the way many women decide to prioritize themselves.

✨ Because when a woman trusts herself, chooses wisely, and dedicates time to herself, everything starts to make more sense.

Results feel better when they come from a focused formula🤍

HD Melatogen Serum has been evaluated in an in vitro efficacy study, showing a 185.7% increase in firmness and collagen synthesis after 96 hours, compared to untreated skin.

This measured result helps explain the formula’s role in supporting visible skin firmness through a research-led approach.

A clear efficacy result, with a formula designed for daily skin support🤍

Firmness isn’t built on big promises. It’s built on consistency and well-constructed formulas. 🤍

Redefiner Serum delivers a weightless fluid-gel texture that melts in fast and feels fresh on skin. It layers easily, sits comfortably, and works well as a daily step without adding weight or shine. ✨

With regular use, it helps improve the feel of elasticity and soften the appearance of expression lines, leaving skin looking firmer, smoother, and more balanced 🤍

The essentials, done properly 🧪✨

At HD, when we talk about results, we talk about how they’re verified🧪

An efficacy study helps validate, through objective evaluations, what benefit was measured in a formula, and under which conditions. That’s why we work with defined protocols and specialized centers.

So trust can be built on data. 🤍
