Cosmedix Radiance Age Restorative Serum 30ml
Description
Description
Anti-aging serum with EGF, trehalose, and peptides for mature skin
EGF — Epidermal Growth Factor — is one of the most researched ingredients in modern dermatology. Discovered by Stanley Cohen, who won the Nobel Prize in Medicine in 1986 for this groundbreaking work, EGF is an endogenous molecule that drives skin renewal and plays a key role in wound healing processes. In the cosmetic world, rh-Oligopeptide-1 (recombinant human EGF) is one of the most targeted ingredients for those seeking visible results in skin firmness, fine lines, and repair — an ingredient rarely found in this concentration in skin products.
Cosmedix Radiance is a concentrated repair serum that combines EGF with an arsenal of antioxidants (Spin Trap, resveratrol, alpha-lipoic acid, glutathione, SOD) and copper peptides for structural skin repair. The formula is specifically designed for mature, damaged, or menopausal skin that needs more than a regular anti-aging serum. In addition to antioxidant protection, it also contains AGP Complex and mild exfoliants that aid cell renewal. Suitable for both morning and evening use on cleansed, toned skin.

Active ingredients
rh-Oligopeptide-1 (EGF, Epidermal Growth Factor): The star of this formula. EGF is a naturally occurring signaling molecule in the body that stimulates the production of new skin cells and collagen. Recombinant human EGF (rh-Oligopeptide-1) is bio-identical to the natural variant and is efficiently recognized by the skin. When applied topically, EGF helps reduce the visibility of wrinkles, supports skin texture, and stimulates the natural repair process of damaged skin — an ingredient used in medicine for wound healing.
D-trehalose: A natural sugar known as the 'survival molecule' in science. Retains moisture in the skin under the most stressful conditions — dry air conditioning, cold wind, exposure to UV radiation. Instantly gives a fuller, smoother appearance to mature skin.
Spin Trap (Phenyl T-Butylnitrone): A high-quality antioxidant with selective action. Captures harmful free radicals without affecting healthy oxygen molecules — an advanced antioxidant among the more targeted protectors in modern cosmetics.
R-Lipoic Acid (Thioctic Acid): A powerful antioxidant soluble in both water and fat, allowing it to work in all layers of the skin. Reduces the visibility of pigmentation spots and contributes to a more even appearance.
Resveratrol (Polygonum Cuspidatum extract): The famous antioxidant from red wine research. Protects the skin against photoaging and helps support skin structure at the cellular level — an effect visible after weeks of consistent use.
L-Superoxide Dismutase (SOD): An enzyme that is among the most powerful natural antioxidants in the body. Neutralizes the harmful superoxide radical before it can react with skin cells.
L-Glutathione: The "mother of all antioxidants" according to many skin scientists. Plays a central role in the skin's natural detox system and also affects pigment regulation for a more even complexion.
Aminoguanidine HCl: A lesser-known ingredient that intervenes in glycation — the process where sugars bind to skin proteins leading to stiffness and wrinkles. An advanced anti-aging pathway found in few serums.
Tetrahydrocurcuminoids: A patented form of curcumin with proven antioxidant effects. Helps protect the skin against photoaging and contributes to a more even complexion over the long term.
Copper Gluconate: A form of copper that supports the natural production of collagen and elastin in the skin. Works synergistically with EGF for structural skin repair.
Grape extract: A natural source of polyphenols and resveratrol that enhances the serum's antioxidant effect.
Fullerenes: An advanced nanotechnological antioxidant that is up to 172 times more effective than vitamin E in laboratory tests. Among the most advanced ingredients in modern anti-aging cosmetics.
Neem and turmeric extract: Two plant-based ingredients from the Ayurvedic tradition with soothing and skin-protecting effects. Also make the serum suitable for sensitive mature skin.
Aubergine extract and pearl powder: Two additional ingredients that nourish the skin and support a radiant appearance.

Frequently Asked Questions
What is EGF and why is it so remarkable in this formula?
EGF (Epidermal Growth Factor) is a signaling molecule naturally produced by the body to regulate cell renewal and skin regeneration. Its discovery earned Stanley Cohen the Nobel Prize in Medicine in 1986. In the cosmetic world, rh-Oligopeptide-1 (recombinant human EGF) is an ingredient found in few serums due to the complexity and cost of production. It works differently from peptides — EGF activates specific receptors on skin cells that stimulate the production of new skin and collagen.
When will I see the first results from Radiance?
The moisturizing and soothing effects can be felt within a few days. For structural improvement of fine lines, firmness, and skin tone, daily use for 8 to 12 weeks is recommended. EGF works at the cellular level, which takes time — but the long-term results are among the most remarkable in anti-aging cosmetics.
Is Radiance suitable for sensitive skin?
Yes, the formula is explicitly designed for mature and sensitive skin. Neem, turmeric, and aubergine extracts have a soothing effect, while the absence of retinol or harsh acids makes the serum tolerable. The formula does contain a low concentration of gluconolactone (PHA) and denatured alcohol — those who are highly sensitive to alcohol-containing formulas may want to do a patch test first.
Can I use Radiance during pregnancy or breastfeeding?
The formula contains no retinoids or salicylic acid, which removes common objections. EGF itself is not explicitly excluded during these periods, but when in doubt always consult your midwife or skin therapist — the discussion around growth factors during pregnancy is scientifically nuanced. For maximum safety, bakuchiol (Cosmedix Bakuchiol Complete) is a more widely accepted anti-aging option during pregnancy.
Can I combine Radiance with other active ingredients like retinol or vitamin C?
Yes, and it is even recommended for maximum results. Classic routine: Radiance in the morning followed by SPF, in the evening a retinol product like Define or Serum 16. The antioxidants in Radiance also protect the stability of vitamin C products in the same routine. EGF works complementarily with retinol — both stimulate skin renewal but through different mechanisms.
What is the difference between Radiance and Affirm?
Both are antioxidant serums with overlapping ingredients (Spin Trap, resveratrol, SOD, glutathione). The core difference lies in their action: Radiance focuses on structural skin repair through EGF and copper peptides — for mature or damaged skin that needs more than antioxidants alone. Affirm focuses on antioxidant protection and firming peptides — more suitable for preventive anti-aging. Many users alternate both; for maximum results on mature skin, Radiance is the more targeted choice.
Why is Radiance sometimes hard to find on the official Cosmedix website?
Cosmedix periodically reviews its range, and some products are temporarily removed from the main collection or offered through other channels. Radiance remains an established Cosmedix bestseller and is usually available through major retailers and spa partners. When in doubt about authenticity, always verify through an authorized Cosmedix distributor.
How long does a 30ml bottle last?
With daily use twice a day, a bottle usually lasts two to three months. When used both morning and evening, this comes down to one and a half to two months. The concentrated formula with EGF requires only a small amount per application.
