Does the skin lose its radiance with age – myth or reality?

No, it is definitely not just a feeling. Scientific research proves that the loss of radiance associated with skin ageing is a biological reality. At first glance, the notion of skin radiance may seem vague, abstract, or even entirely subjective. However, science has proven that the concepts of radiance and a dull complexion are not merely a matter of individual judgement. On the contrary, it is a variable comprising various parameters that can be measured using sophisticated instrumental methods. And it is on this basis that studies – notably a landmark 2023 study by a Japanese team (1) – have confirmed that: yes, a dull complexion does indeed increase biologically with age. 

Skin ageing causes biological and biophysical changes that directly affect the factors associated with radiance. Changes in the skin’s structure, function and composition affect the smoothness of its surface, its optical uniformity and its. Unfortunately, the combination of these factors leads to a loss of skin radiance, which is positively correlated with age. This is a multidimensional dulling of the skin, linked to interdependent phenomena.

Yes, and that’s the good news in this feature. Admittedly, ageing does affect the skin’s radiance through biological processes whose existence is undeniable. Nevertheless, research shows that it is possible to preserve, or even enhance, the radiance of mature skin . Certain studies, including one from 2025 examining the effects of oral supplementation (6), confirm that the radiance of the complexion is not a fixed measure, but rather depends on factors, some of which are variable and can be partially modulated. In fact, it is entirely possible to capitalise on the plasticity of certain skin parameters considered to be more or less ‘correctable’ in order to reconcile ageing with a radiant complexion.   

Below are the factors you can most easily influence, according to science:

• Moisture balance: apply moisturising formulas (serums, creams) to increase the water content of the upper layers of your epidermis. The result: a smoother surface that enhances specular reflection. Examples of active ingredients: niacinamide, hyaluronic acid

• Skin tone: use active ingredients that combat dark spots, such as those that target melanin transfer and melanosome activity. This gives you the best chance of achieving an even complexion that also looks more radiant. Examples of active ingredients: niacinamide (7), vitamin C

• The skin’s surface: incorporate exfoliating products into your skincare routine to reduce roughness, whilst simultaneously stimulating epidermal cell renewal and collagen production. This ‘new skin’ effect is known to restore radiance very quickly. Examples of active ingredients: retinal, AHAs

• Biochemical interactions: opt for skincare products with antioxidant properties to preserve your skin’s visual and structural balance. With skin that is better equipped to combat oxidative stress, your complexion should gradually become more radiant. Examples of active ingredients: vitamin C, vitamin E.

Myth or reality?

It is indeed a well-documented fact: yes, the skin gradually loses its radiance as we age. This is a biological phenomenon based on measurable variables, such as optical properties, roughness and colourimetry.

What is true

• The loss of radiance is both a clinical sign and a perceptible marker of skin ageing

• The skin becomes increasingly dull as we age, in response to profound changes that alter its physical and biological characteristics

• Restoring a radiant complexion is one of the main concerns for mature skin, on a par with wrinkles and dark spots, to which radiance is closely linked.

What is incorrect

• A dull complexion is not merely a subjective phenomenon that varies according to individual perception

• Age-related loss of radiance is not necessarily irreversible: it is possible to partially halt it by targeting some of its contributing factors.

Food for thought

Common expressions such as ‘looking a bit pale’, ‘looking glum’ or ‘looking washed out’ highlight the prominent role that a radiant complexion plays in our human interactions. Associated in the collective imagination with health, youth and beauty, the quest for radiance stems largely from a social construct, and it is legitimate to question the possible underlying cognitive biases. Beyond purely aesthetic criteria – and given that science suggests that radiance itself is a shifting criterion – this opens up the possibility of redefining the very notion of radiance by attributing a similar dynamic to the term itself. Rather than speaking of a generic ‘glow’, would it not be more relevant to consider ‘glow’ according to specific criteria, particularly those related to age? Consequently, the description of ‘radiant skin’ would be understood according to different criteria at the age of 20… and at the age of 60. For whilst cosmetics can help to modulate or partially improve the radiance of mature skin by acting on its correctable parameters, no formula can restore a youthful glow to skin that has already weathered the trials of time. Rather than dreaming of promises watered down by marketing rhetoric, it seems wiser to set realistic and motivating goals. Maintaining skin that feels comfortable and is sufficiently protected to age gracefully, with a balance of harmony and vitality: this is perhaps the finest radiance that mature skin can achieve.

Maintaining the radiance of mature skin requires a multi-pronged approach. We recommend focusing your skincare routine on protection, hydration, exfoliation, evening out skin tone and dermal restructuring. It may also be beneficial to enhance the effects of your topical skincare products by combining them with a suitable dietary supplement.

Mature skin is more sensitive than it was in youth, partly due to the thinning and weakening of its hydrolipidic film. This is why it may react negatively if exposed to formulations that are too harsh for it. Take particular care when using products containing vitamin C, retinoids or exfoliating active ingredients, such as fruit acids. Feel free to introduce them gradually into your routine by slowly increasing the frequency of use and the dosage if your skin seems to tolerate them. If you use retinol or exfoliating skincare products (always in the evening), always apply a high-factor sun cream the following day. Finally, take care not to layer active ingredients without first ensuring they are compatible. Some formulations designed to improve and even out the complexion can be potent and contain active ingredients that are best handled with care.

A word from the dermatologist

“Does lifestyle have a greater impact on the skin’s radiance than age itself? Fair skin that suffers damage from natural or artificial ultraviolet radiation develops spots, known as solar lentigines, which are markers of exposure. These are accompanied, to varying degrees, by changes in the dermis such as solar elastosis, which causes so-called ‘citrus-peel’ skin, with deep, diamond-shaped wrinkles. Smoking contributes to this appearance and increases the risk of cysts and blackheads. It is therefore not so much age that alters the “radiance of the complexion” but rather extrinsic factors: UV exposure, lifestyle and smoking.”
