Over time, it is not uncommon to see the skin lose its firmness, elasticity and tone. This phenomenon of sagging skin affects both the face and the body. It can appear as early as your thirties, gradually becoming more pronounced with age, weight fluctuations or certain environmental factors. Whether it is a less defined facial contour, wrinkled skin on the neck, or visible sagging on the arms, stomach or thighs, these signs are often experienced as a loss of radiance, tone and youthfulness.
Fortunately, aesthetic medicine now offers many effective and safe non-surgical solutions to firm the skin and stimulate deep skin tissue. In this article, we will explore why skin slackens and what are the best options for remedying this without surgery, thanks to technological advances such as radiofrequency, ultrasound, microneedling and biostimulator injections. These modern techniques are accessible and tailored to each skin type, helping you to achieve firmer, smoother and visibly rejuvenated skin.
I. Why does skin slackening occur over time?
Skin slackening is a normal phenomenon that affects all skin types, to varying degrees depending on age, lifestyle and genetics. It involves a gradual loss of skin firmness and elasticity. It can manifest as sagging facial features, wrinkled skin on the neck or décolleté, or a withered appearance on certain areas of the body. To better understand how to combat this sagging of the skin on the face and body, it is essential to know its causes.
1. Natural ageing of the skin on the face and body
Over the years, our skin undergoes a series of inevitable biological changes. From the age of 25 to 30, the production of collagen — the protein that gives skin its structure — begins to slow down. Added to this is a decrease in the production of elastin, which allows the skin to stretch and return to its original position after movement.
At the same time, the amount of hyaluronic acid naturally present in the dermis also decreases, reducing the skin’s ability to stay hydrated and plump. Cell renewal slows down, the skin becomes thinner and more fragile, and gradually loses its density.
The result: skin tissue slackens, facial contours become less defined, and certain areas of the body begin to « sag » or appear wrinkled.
2. Factors that aggravate skin slackening
Although skin ageing is an inevitable process, certain factors can accelerate or aggravate this slackening of the skin on the face and body:
Excessive sun exposure: UV rays break down collagen and cause visible « photoaging, » particularly on the face, neck, décolleté, and hands.
Tobacco: it generates free radicals that destroy the skin’s support fibres and disrupt microcirculation.
Pollution and oxidative stress: these accelerate skin ageing by damaging cells.
Hormonal changes, particularly during the menopause, play an important role in skin slackening, especially in women. The decline in oestrogen leads to a loss of skin density.
Rapid or significant weight loss: when the body loses a lot of weight, the skin, which has often been stretched for years, is not always able to regain its original tone, especially in the absence of muscle activity.
Lack of physical exercise: when the underlying muscles are not used much, they lose tone, which accentuates the appearance of sagging skin.
Dehydration and an unbalanced diet: skin that is poorly nourished from within lacks essential nutrients (vitamins, trace elements, amino acids), which affects the quality of the skin on the face and body.
3. The areas most affected by skin slackening
Skin slackening does not affect all areas of the body in the same way. Some areas are more exposed, thinner or more mobile, and therefore more likely to slacken over time:
The face: the oval of the face loses its definition, the cheeks sag, the nasolabial folds deepen, and the eyelids may droop slightly.
The neck and décolleté: often overlooked areas in beauty routines, their thin, exposed skin quickly shows signs of sagging.
Arms (« bat wings »): often weakened by muscle loss or rapid weight loss.
The tummy: particularly after pregnancy or significant weight loss.
Thighs and knees: gravity, loss of muscle mass and friction can accentuate the appearance of loose, wrinkled skin.
Understanding the mechanisms of skin slackening allows us to take more targeted and effective action. While it is impossible to stop time, it is entirely possible to visibly slow down its effects through a combination of good habits and appropriate non-invasive treatments — which we will explore in the following chapters.
II. How can skin slackening be prevented?
Skin slackening does not happen overnight. It develops gradually, often discreetly, before becoming more visible. The good news is that it is possible to slow down this process by adopting effective preventive measures, both in your skincare routine and in your overall lifestyle. Prevention starts early — as early as age 30 — and plays a key role in the quality of skin ageing.
1. Good daily habits to maintain skin quality
🔆 Protect your skin from the sun all year round
Exposure to UV rays is one of the main causes of skin slackening. UV rays break down collagen and elastin and cause oxidation of skin cells. Even on cloudy days or in winter, UVA rays penetrate deep into the dermis.
The right reflex: apply SPF 30 to 50 sunscreen every morning to your face, neck and décolleté. A simple but essential step to prevent loss of firmness.
💧 Deeply moisturise the skin
Well-hydrated skin is more supple, plumper and better equipped to fight against external aggressions. Hydration also helps maintain a healthy barrier function, which is essential for cell renewal.
The right reflex: use a moisturiser suited to your skin type every day, enriched with hyaluronic acid, glycerine or ceramides. For the body, choose nourishing textures (butters, milks, oils) for fragile areas such as the arms or stomach.
🥗 Adopt a diet rich in antioxidants
What we put on our plates has a direct impact on our skin. Antioxidants neutralise the free radicals responsible for premature skin ageing. Collagen, vitamin C, zinc and omega-3 are all essential allies in preserving skin firmness and elasticity.
The right reflex: regularly consume red fruits, green vegetables, oily fish, oilseeds, seeds, green tea, etc. And limit sugar, alcohol and ultra-processed foods.
🏃♀️ Exercise regularly to stimulate circulation
Physical activity promotes muscle toning and improves skin vascularisation. It also helps stabilise weight, preventing sudden fluctuations that can stretch and weaken the skin.
The right reflex: incorporate brisk walking, yoga, Pilates, swimming or muscle strengthening into your daily routine. These activities support deep muscles and skin.
🧴 Adopt targeted cosmetic care
Certain cosmetic ingredients are known for their ability to stimulate collagen and improve skin firmness. They effectively complement other daily skincare routines.
Assets to look for:
Retinol: stimulates collagen production, smoothes and firms
Peptides: support the skin’s supporting fibres
Vitamin C: antioxidant, stimulant and brightening agent
Fruit acids (AHAs): gentle exfoliants that boost cell renewal
Niacinamide: strengthens the skin barrier and improves elasticity
The right approach: gradually incorporate these products into your routine, following the advice of your cosmetic doctor or dermatologist.
2. The role of dietary supplements and nutricosmetics in skin slackening
While diet remains the foundation, dietary supplements can offer a targeted boost, especially during periods of fatigue, stress or hormonal changes that cause skin slackening.
Ingredients to prioritise:
Hydrolysed collagen (marine or bovine): improves skin density and firmness
Hyaluronic acid: for deep hydration and a « plumping » effect
Vitamin C: necessary for collagen synthesis
Zinc, selenium, copper: for their antioxidant action
Organic silicon: strengthens connective tissue
Omega-3 (EPA/DHA): to improve skin elasticity and hydration
The right approach: choose 2- to 3-month courses of treatment, several times a year, favouring quality brands that have been validated by clinical studies.
In summary, preserving skin firmness requires a comprehensive approach: sun protection, a balanced lifestyle, appropriate skincare and targeted stimulation. These measures help to slow down the signs of sagging and skin ageing, as well as maintaining toned skin, even as time goes by.
III. What aesthetic medicine solutions are available to slow down skin slackening and firm the skin?
When the skin loses its firmness, it is entirely possible to intervene without surgery, thanks to innovative and non-invasive treatments. Today, aesthetic medicine offers effective solutions to stimulate the production of collagen, elastin fibres and hyaluronic acid, redensify tissues and firm up slackened areas, while maintaining a natural and harmonious appearance and skin quality.
Here are the most widely used techniques, recognised for their effectiveness.
1. Conventional radiofrequency: gentle heat and collagen reinforcement
Conventional radiofrequency treatment uses electromagnetic waves that cause controlled heating of skin tissue (between 39°C and 42°C), thereby stimulating fibroblasts to produce more collagen and elastin. The heat also causes existing fibres to contract, giving an immediate tightening effect.
There are different types of radio frequency:
Monopolar: acts deeply, ideal for body areas (arms, stomach, thighs).
Bipolar or multipolar: more superficial, specific to thin skin or the face, with or without wrinkles or fine lines.
Exion® radiofrequency is combined with ultrasound: hyaluronic acid production increases by up to 224%, combined with a 47% increase in collagen, contributing to skin firmness and deep hydration.
Benefits of this treatment:
Non-invasive and painless
Without social exclusion
Suitable for all skin tones
Indications:
Mild to moderate sagging skin on the face, neck and décolleté
Sagging skin on the arms, stomach or thighs
Frequency: 4 to 6 sessions at 2- or 3-week intervals, followed by quarterly maintenance sessions.
2. Morpheus 8 fractional radiofrequency or Exion fractional radiofrequency: deep stimulation with visible results
Unlike conventional radiofrequency, fractional radiofrequency combines microneedles and heat to act at specific depths in the dermis. It can be used to treat moderate to severe skin laxity with a lasting restructuring effect. The best-known devices are Morpheus8® and Exion® Fractionated.
Operation:
Very fine needles penetrate the skin to deliver thermal energy directly into the deep dermis.
This dual mechanical and thermal effect triggers intense neocollagenesis (collagen production) as a preventive or curative measure, particularly in men and women before or after the menopause.
Benefits of this treatment:
Overall skin redensification
Lifting effect without surgery
Gradual but profound results
Suitable for mature and sagging skin
Indications:
Sagging facial contours, presence of wrinkles and fine lines
Wrinkled eyelids and eye contour
Neck, décolleté, arms, stomach
Frequency: 2 to 4 sessions spaced one month apart, then one to two maintenance sessions per year. Recovery time: redness or small dots visible for 24 to 48 hours, easily concealed.
3. Microneedling (classic or fractional radiofrequency)
Conventional microneedling creates controlled micro-perforations in the skin, activating a natural regeneration process. This mechanical stimulation increases collagen and elastin production, improves skin texture and firms sagging skin.
Benefits of this treatment:
Overall improvement in skin tone, pore appearance, wrinkles and scars
Safe for all skin types, even pigmented skin
Treatment adaptable to each area
Indications:
Mild to moderate facial sagging
Thin or wrinkled skin on the décolletage
Flabby arms or stomach
Frequency: 3 to 4 sessions at one-month intervals, then biannual maintenance.
4. Skinbooster and biostimulator injections to prevent skin slackening
Skin boosters (such as NCTF® 135HA and Profhilo®) are micro-injections of highly fluid, non-volumising hyaluronic acid, sometimes enriched with numerous products such as vitamins, minerals or amino acids. They improve the skin’s hydration, density and suppleness.
Biostimulators (the products used are polylactic acid and calcium hydroxyapatite, such as Radiesse®) act more slowly but offer deep collagen stimulation, which is ideal for more pronounced sagging and fine lines and wrinkles.
Advantages:
Natural and gradual results
Very good tolerance
Suitable for delicate areas (face, neck, décolleté, arms, hands)
Frequency of these treatments:
Skinboosters: 2 to 3 sessions, spaced 3 weeks apart, then 1 to 2 maintenance sessions per year
Biostimulators: 1 session every 1 to 2 months depending on the product, visible effects over several months
6. Jet Peel®: oxygenation and immediate toning effect on the skin
The Jet Peel® is a gentle yet powerful treatment that propels a jet of air enriched with active ingredients (hyaluronic acid, vitamins, amino acids, proteins, peptides) at very high speed to exfoliate, moisturise and oxygenate the skin deep down without needles and without pain.
Benefits of this treatment:
Immediate improvement in tone and radiance
Very pleasant and relaxing
Perfect as a complement to deeper treatments
Indications:
Dull or tired skin
Wrinkled décolletage, neck, hands
Post-treatment maintenance or event preparation
Frequency: 3 to 4 sessions as a course of treatment, then one session every 2 to 3 months for maintenance.
In the next chapter, we will look at how to choose the best treatment for sagging skin for each skin type, age and need, based on a personalised assessment by your cosmetic doctor.

IV. How to choose the right treatment for sagging skin in Paris?
Given the wide range of technologies available, it can be difficult to know which treatment is best for your situation. Every skin is unique, as are the causes and severity of sagging skin on the face and body. That is why it is essential to have a personalised approach, supervised by a qualified professional, to ensure natural, effective and long-lasting results.
1. The importance of a personalised cosmetic medical assessment
Before starting any treatment, a consultation with a cosmetic doctor is essential. This assessment allows you to:
Assess skin quality: texture, thickness, tone, elasticity, wrinkles or fine lines.
Identify the main causes of sagging skin on the face or body: hormonal ageing, weight loss, sun exposure, lack of hydration, etc.
Determine the degree of laxity: mild, moderate, or advanced.
Consider age, lifestyle, and medical history.
Understanding patient expectations: natural effect, subtle facelift, overall improvement, preparation for an event, anti-ageing treatment, etc.
This assessment enables the doctor to develop a tailored protocol for the most suitable technique, taking into account the individual’s objectives, budget, availability and skin type.
2. Adapt the treatment to the area and degree of sagging
The solutions will vary depending on whether:
The face (oval shape and sagging cheeks, drooping eyelids, wrinkles and fine lines),
Neck and décolleté (thin, wrinkled skin, fan-shaped wrinkles or necklace wrinkles),
Arms (skin ptosis, ‘bat wings’),
From the abdomen or thighs (sagging after pregnancy or weight loss).
👉 Some examples of choices:
Slight facial sagging from age 30–35 onwards: conventional radiofrequency, microneedling, skin boosters.
Moderate sagging of the face or neck: fractional radiofrequency (Exion® fractional, Morpheus8®), biostimulators.
Sagging stomach or arms: monopolar radiofrequency, fractional radiofrequency.
Wrinkled skin on the décolleté or hands during menopause: skin boosters, Jet Peel®, NCTF® 135HA, fractional radiofrequency (Morpheus8® or Exion® Fractional).
3. Synergy of treatments: the key to effective skin rejuvenation
Often, combining several techniques yields the best results. Each treatment acts at a specific depth: on the surface (Jet Peel®), in the dermis (radiofrequency, microneedling). By combining these approaches, a comprehensive, harmonious and enhanced response is achieved.
👉 Examples of combined protocols:
Fractional radiofrequency + skin boosters: deep firming + intense hydration.
Microneedling + Jet Peel®: mechanical stimulation and surface nutrition.
Conventional radiofrequency + lipocavitation or cryolipolysis (for the body): skin firming + reduction of fat deposits.
Radiofrequency + Jet Peel®: firming, skin elasticity and radiance
The doctor always adapts the protocol to the skin type, the season, the patient’s tolerance, hormonal status such as during menopause, and availability for sessions.
4. What results can be expected in terms of skin slackening? And over what period of time?
Most treatments require several sessions spaced out over time, with gradual improvement over several weeks to months. Collagen regenerates slowly, but the effects can last between 6 and 18 months depending on the technique used, lifestyle habits and maintenance.
Maintenance is essential to ensure lasting results: one or two sessions per year are often enough to maintain firmness and slow down the natural process of sagging.
A holistic approach: beauty, prevention and wellbeing
Beyond technology, it is important to adopt a healthy lifestyle to support and prolong the results:
Diet rich in antioxidants and high-quality protein
Regular physical activity (weight training, yoga, swimming)
Restorative sleep and stress management
Home cosmetic treatments rich in anti-ageing active ingredients
Daily sun protection
This synergy between beauty treatments, nutrition, exercise and skincare allows for deep skin treatment, but also boosts self-confidence.
