RD Cosmetic offers an innovative solution to improve skin regeneration and firmness, inspired by its commitment to making science accessible to the services of skin health.

Following several in vivo and in vitro laboratory tests, experts have raised an impressive number of transferable properties in humans. These include: Percutaneous absorption of active ingredients down to the dermis. The regenerating power of our biocompatible products are so effective that they are healing and healing. Also used in post-surgery, healing management, post-laser and 2nd degree burns.
Why use marine collagen rather than collagen from another source, such as bovine collagen?
Marine collagen has several advantages. Extracted from the skin, bones and scales of fish, its fibrous proteins ensure the elasticity, firmness and suppleness of the skin. It contains oligopeptides of excellent quality, and has better bioavailability: which optimizes its absorption by the body. RD Cosmetic prefers it for its superior sanitary control in terms of controlling the scientific operations surrounding its extraction, and for several other reasons.
What is the importance of stem cells in anti-aging treatment?
Organic silicon reduces the effects of stress on the skin. It provides protection against the effects of cortisol (dehydration, degradation, delayed healing).
It optimizes the dynamic link between fibroblasts and elastic fibers. It also stimulates the synthesis of hyaluronic acid and the optimization of cellular communications.
How long will my products remain in good condition after opening them?
Our products come in a tube format, to avoid any form of contamination: this allows an optimal duration of the contents. If stored properly (and uncontaminated), each tube can last between 24 and 36 months.
My skin doesn't always respond well to facial creams. How do I know if RD Cosmetic cosmeceuticals are suitable for my skin type?
Our products are hypoallergenic. They have been tested by an external laboratory. Our cosmeceuticals are suitable for all skin types, even the most sensitive and oily.
What is the difference between cosmeceuticals and traditional cosmetics?
The main difference between cosmeceuticals and cosmetics is that cosmeceuticals contain highly concentrated active ingredients to target specific skin concerns at a deeper level, while traditional cosmetics aim to improve appearance more superficially. Cosmeceuticals are therefore more effective for concerns such as wrinkles, acne, or hydration, and are often used in conjunction with aesthetic treatments. Also, cosmeceuticals contain bioactive ingredients with scientifically proven properties.
At what age should I start including collagen and elastin in my beauty routine?
Around the age of 25, collagen and elastin production slows down. Collagen and elastin production then decreases by approximately 1% per year. It is therefore important to nourish the dermis with elastin and collagen from the age of 30; this is where the deficiency of these proteins becomes more evident.
This same research also suggests that younger clients can optimize their skin's natural firmness, volume, and tone by first adopting healthy habits. Proper hydration and a diet rich in vitamins and minerals are just a few examples. However, the best habit to adopt—regardless of age—remains protecting yourself from UV rays.
Why are DERMA COLLAGEN and DERMA ELASTIN unique?
RD Cosmetic products are a new skincare protocol for your daily routine; they are included before applying any creams or serums. Their role: to densify the skin to make it more resistant to external aggressions. They address the underlying problem of the skin's fundamental structure to improve the quality and health of your skin. The result is a radiant complexion, reduced wrinkles and fine lines, and tightened pores. See before-and-after photos from our partners.
What types of treatments can benefit from the post-treatment regenerative effect of DERMA COLLAGEN?
- Post-Laser
- Fractional Laser
- Scar management
- Stretch marks
- Burns
- Micro-needling
- Any technology
Any treatment that requires a recovery period necessary for cell regeneration of the dermis of the skin.

If I want to use RD Cosmetic cosmeceuticals to reduce the signs of aging (fine lines, lack of volume, etc.), what kind of concrete results can I expect?
I already get great results with RD Cosmetic products. Should I stop using them or change the frequency of use or my routine?
We suggest that you continue to apply your products, even if you are already satisfied with the results.
We are a daily anti-aging and firming solution. We provide the skin with essential active ingredients to strengthen the quality and protective barrier of your skin. So, you must include the application according to your age daily to maintain your visible and concrete results.
Remember biotechnology is at the service of the health of your skin. Know that the skin is in an aging process and has been since the age of 25, so you lose 1% of your proteins and the older you get, the more this percentage increases.
