A new way to understand skin response✨

Skin is constantly interacting with its environment. Stress, pollution, sleep, sun exposure, and changes in routine can all influence its balance and the way it looks and feels day after day

Through epigenetic research, HD studies how these external factors may influence skin response, without modifying the DNA, to develop active ingredients such as EpigenCur®.

An active ingredient designed to support the skin against the effects of external stress and help maintain its daily balance.

Because more precise dermocosmetics begin with understanding how skin responds🤍

What if your serum could support the look of firmer skin?

HD Redefiner Serum was evaluated in an efficacy study designed to measure elastin gene expression, a key marker associated with skin elasticity and structural support.

After topical application and 4 hours of incubation, the serum showed a significant +72.1% increase in elastin gene expression compared to the untreated control group.

Because firmer-looking skin starts with targeted support ✨

What makes Redefiner different?

A formula built around skin structure, firmness and visible definition.

Biopolymer Tensor helps create a lifting effect.�EpigenCur® supports skin under daily stress.�Scutellaria Baicalensis helps improve the appearance of firmness and elasticity.

Together, Redefiner Serum and Redefiner Cream work as a complete routine for skin that needs more density, smoothness and support

Because effective skincare starts with the right formula✨

Dads always have a piece of advice on hand. Today, for once, the advice is for them. 🧡

Skincare isn't about age or showing off: it's just one more way of looking after yourself, like staying active or sleeping well. And men's skin appreciates a little attention too.

We asked dermatology to lend us a hand and gathered the essentials: what truly makes a difference and why, in simple steps that fit into any day.

Swipe, take a look, and send them to your dad.

👉 Sometimes the best gift is the kind you notice over time.

As skin changes over time, it can begin to lose firmness, elasticity and the visible structure that keeps contours looking defined.

The Redefiner routine is designed to support skin through those changes with three targeted steps: cleanse, serum and cream.

Start with Detoxifier Foam to remove impurities and pollution residue. Apply Redefiner Serum to help improve the look of firmness, elasticity and skin density. Then finish with Redefiner Cream to nourish, smooth and support more defined-looking facial contours.

A precise routine for firmer-looking, more revitalized skin.

Real skin has real needs.

Some days it asks for hydration. Others, for comfort, balance, radiance or repair.
At HD Cosmetic Efficiency, we create formulas designed to respond to those needs with a science-led approach, thoughtful textures and visible results.

Skincare made to support your skin, every day, with purpose, precision and care✨

Skin aging is not shaped by genetics alone.

It is also influenced by what skin experiences every day: sun exposure, stress, pollution, rest, lifestyle habits and the environment around it.

Epigenetics helps us understand how these factors may influence the way skin behaves, protects itself and responds over time, acting on gene expression.

At HD, this approach inspires formulas designed to work in harmony with the skin’s natural balance, helping protect it from daily skin stress, support the skin barrier and maintain a firmer, more resilient, healthy-looking appearance.

Because caring for your skin today also means supporting how it responds tomorrow ✨

Support. Smoothness. Definition.

The Redefiner ritual combines Detoxifier Foam, Redefiner Serum and Redefiner Cream to help prepare the skin, support elasticity and improve the appearance of firmness and texture.

For skin that wants a more structured-looking appearance, with a routine that feels complete, lightweight and easy to follow✨
