Over time, skin on the face and body begins to sag. It loses elasticity and volume: the facial contours droop and the body becomes less toned. Wondering how to firm skin and combat skin ageing? Here is our advice.

Causes of skin firmness loss

Age

Loss of firmness is perfectly normal. Elastin, collagen and hyaluronic acid are essential for supple, plump skin. Unfortunately, their natural production declines over time. From age 25, levels of hyaluronic acid, the molecule responsible for tissue hydration, decrease. Skin starts to become dehydrated and less toned.

Around age 30, collagen production is affected. These fibres, which maintain cohesion between the dermis and epidermis, become less abundant. Skin starts losing elasticity and sagging. At the same time, fibroblasts begin producing less elastin. This protein helps skin return to its shape after stretching, so sagging begins to develop.

Oxidative stress

Tobacco, stress, pollution and sun all attack the skin. They create free radicals that alter skin tissue, particularly the fibroblasts responsible for collagen and elastin production.

Hormonal changes

Hormonal fluctuations are another factor to consider when looking to firm skin. Pregnancy can affect firmness, but the effects are most visible at menopause. Hormones, essential to tissue function, undergo major changes. Fibroblast activity slows further, accelerating firmness loss.

Changes in weight

Rapid weight gain and loss weakens tissue. Over time, this leads to a loss of tone and firmness.

Key ingredients for effective skin firming

To help the skin maintain its firmness, we recommend you turn to 3 key ingredients:

Hyaluronic acid

This essential skin component is a must for tackling sagging. Able to absorb up to 1,000 times its weight in water, it is a key active ingredient for restoring elasticity and hydration.

Ultra-corrective Micro-Algae Oil

This NUXE-patented active ingredient is extracted from Chlorella Vulgaris, known for its regenerative abilities. The oil strengthens skin’s internal structures and provides a lifting effect.

Green tea complex and rye extract

This firming duo helps the skin regain its softness and elasticity.

Skincare tips to improve firmness

Want to discover our secrets for firmer skin? We have 5 little tips to help you combat sagging:

The scrub

Exfoliate once or twice a week, on both face and body. Your movements tone skin tissue while removing dead cells, helping skin benefit more from the firming active ingredients in your skincare.

Moisture

Apply daily moisturizing treatments to support the action of hyaluronic acid and maintain soft and firm skin.

Cold water jet

Finish your shower with a cold stream of water over your whole body. Work upwards from the feet for an instant tightening effect.

Massages

Take the time to apply your care by massaging your skin. You thus boost the blood circulation: the production of collagen and elastin in the dermis is stimulated for a firmer skin.

The sunscreen

Always protect your skin during sun exposure to preserve its youthful appearance.

Used daily, these simple habits naturally support your firming skincare without replacing it. They prepare skin to absorb anti-ageing active ingredients better and prolong their benefits. For visible results, combine them with a complete anti-ageing routine suited to your skin type, remembering that consistency is key to lasting firmness.
