Ultimate Guide to Firm Your Skin Effectively

Aug 14, 2025

On both the face and the body, skin slackens over time. It loses elasticity and volume: the facial oval softens and the body feels less toned. Wondering how to firm your skin and combat signs of aging? Here’s our advice.

Causes of Skin Firmness Loss

Noticing that your skin is starting to sag? It’s normal—many factors influence skin firmness:

Age

Loss of firmness is a completely natural process. Elastin, collagen, and hyaluronic acid are essential for keeping skin supple and plump, but their production declines with time.

Around age 25: Hyluronic acid - the molecule that helps keep tissues hydrated - begins to decrease. Skin becomes more hydrated and less toned.
Around age 30: Collagen production is affected. These fibers, which support the dermis and epidermis, become less abundant, and skin starts to lose elasticity and slacken. At the same time, fibroblasts produce less elastin. This protein helps skin bounce back after stretching, so reduced elastin contributes to laxity.

Oxidative Stress

Smoking, stress, pollution, and sun exposure generate free radicals that can alter skin tissue—especially the fibroblasts responsible for producing collagen and elastin.

Hormonal Changes

Hormonal fluctuations also affect firmness. Pregnancy can influence skin tone, but the effects are especially visible at menopause. When hormones—vital to healthy tissue function—are disrupted, fibroblast activity slows, accelerating the loss of firmness.

Weight Changes

Rapid weight gain or loss weakens tissues. Over time, these fluctuations can lead to diminished tone and firmness.

Key Ingredients for Effective Skin Firming

To help skin maintain firmness, focus on three key ingredients:

Hyaluronic acid: This ingredient is essential in the fight against sagging. Able to hold up to 1,000 times its weight in water, it helps restore elasticity and hydration.
Ultra-corrective micro-algae oil: A NUXE-patented active extracted from Chlorella vulgaris, known for its regenerative capacity. This oil helps reinforce the skin’s internal structure and provides a lifting effect.
Green tea complex & rye extract: This firming duo helps skin regain softness and elasticity.

Tips to Care for Your Skin and Help It Feel Firmer

Wondering how to firm your skin? Here are simple tips to help address sagging:

Exfoliate: Once or twice a week—face and body. Gentle motions help tone the skin’s surface and remove dead cells, so your skin can better benefit from the firming ingredients in your skincare.
Hydrate: Apply moisturizing products every day to support the action of hyaluronic acid and keep skin supple and firm.
Cold water rinse: Finish your shower with a jet of cold water over the entire body, working from the bottom up, for an instant tightening effect.
Massage: Take time to massage as you apply your products. This helps stimulate circulation, supporting collagen and elastin activity in the dermis for a firmer look.

You’ve been wondering how to firm your skin—now you have the essentials. With consistent daily care—and products that support the skin’s structural fibers and help counter the natural decline in hyaluronic acid—your skin can look more toned and plumper.
