Aesthetic treatments in your 40s:
descent, volume and the order they are treated in

What usually changes in your 40s?

The 40s are when the architecture of the face starts to show its age rather than the surface alone. The deep fat compartments of the mid-face, notably the deep medial cheek fat, deflate, and the bone beneath them, the maxilla and the rims of the eye socket, gradually resorbs, so the skin and the superficial fat above have less to sit on. At the same time the retaining ligaments that pin the mid-face to the bone loosen. The result is a cheek that sits lower and flatter, a nasolabial fold that is now present at rest, a hint of a marionette line, and the beginning of a jowl, which is tissue that has slid below the jawline rather than tissue that has appeared.

The under-eye changes in its own way. The tear trough deepens as cheek support falls away, the fat pads behind the lower lid may begin to push forward as their restraining septum weakens, and the thin skin here starts to crepe. These three look similar in a mirror and need different answers, which is why the eye bags causes page lists four distinct mechanisms. Discrete, sharply bordered sun spots appear on the cheeks and temples from the 40s onward, texture coarsens, and the first horizontal lines settle into the neck. In the late 40s perimenopause begins to thin the skin and lower its oil, which is the subject of the menopause skin page.

The important point is that these changes come from different layers. Descent and volume loss produce similar shadows, and the whole of planning in this decade rests on telling them apart before anything is injected or heated.

What is usually not needed yet?

The 40s are the decade of the premature facelift and the overfilled face, and both come from treating a shadow instead of its cause. The following are usually declined unless the examination finds a reason.

A surgical facelift

Mild to moderate descent with reasonable skin quality, which is what most people in their 40s have, is within the range of non-surgical lifting. Heavy, mobile jowls and marked redundant skin are surgical territory and are referred to a plastic surgery specialist, but that is more often a finding of the late 50s and beyond; the after 50 page describes where that line sits.

Filler used to lift

A filler adds volume; it does not lift. Placing it under tissue that has descended, in the hope of pushing it back up, adds heaviness to a face that has become heavier at the bottom, and the result is the pillow face that is dissolved later. The order is lifting first, then volume only where it has genuinely gone, as the natural look philosophy explains.

Filling the nasolabial fold itself

The fold is usually the shadow of a deflated, descended cheek above it. Filling the line directly flattens the expression and leaves the cause untouched; the nasolabial folds page explains why the cheek is treated first.

Filler into an eye bag, and biostimulators everywhere

Filler suits a hollow with good skin over it, not a bag, which is fat pushing forward; adding volume beside a bag makes the whole area puffier. Biostimulators have a real place in this decade, set out below, but as a diffuse full-face routine in a face that has mainly descended they add bulk that cannot be dissolved.

“A filler cannot lift and a lift cannot replace what has gone. In the forties, getting the order wrong is how a face ends up both heavy and hollow.”

Dr Sin YongOn planning in the 40s

Mid-face descent and jowls: the lifting logic

Descent is approached with energy-based lifting, chosen after the face has been examined for where the tissue has moved and how much the face has to spare. The assessment lifts and releases the tissue to see how it recoils, feels the deeper support, and compares photographs from a decade earlier at the same angle; the jowls page explains why a jowl is a position problem rather than a weight problem, and why it survives every diet.

Dr Sin Yong selects between four approaches. VF Lift – Vertical Facelift is his protocol on Volnewmer monopolar radiofrequency, planned zone by zone along vertical vectors, with no incisions and no injected product; it is radiofrequency, not ultrasound. Thermage FLX is monopolar radiofrequency that heats the dermis in bulk for collagen remodelling, with a long published literature behind it, and suits laxity of the skin envelope, including the eyelids and neck. HIFU delivers focused ultrasound at set depths to the SMAS layer and suits a face with tissue to spare. Time Freeze Laser LCLR® delivers lifting energy at multiple depths with no redness and no downtime, and also has a mode for sagged fat and settled filler. The sagging face page compares them, and the VF Lift – Vertical Facelift vs Time Freeze Laser LCLR® comparison explains how the two protocols are chosen between.

Where threads fit

A thread places absorbable PDO or PCL cogs under the skin to reposition tissue that has slid and to leave a collagen track along its path. The logic is narrow: it suits early jowling with reasonable skin quality and tissue that moves when it is lifted by hand, and it does not remove skin, does not treat fascia that has loosened, and is not a facelift. Dr Sin Yong uses threads as the Bliss Lift for that early, mobile jowl and the VF Lift – Vertical Facelift for broader laxity planned zone by zone; the threads vs fillers for sagging page sets out why neither is the answer to the other's problem. A systematic review of thread-lift sutures found short follow-up in most published series, which is one reason threads are offered here for a defined indication rather than as a general lift.

Volume loss: where fillers and biostimulators fit

Once descent has been addressed, what remains hollow is volume that has genuinely gone, and that is what filler is for. For a specific area, the temple, the cheek apex, the chin or the lips, hyaluronic acid is placed where the support was lost, and it can be dissolved with hyaluronidase if the face later changes. Where the support is bone, such as the chin, the jawline or the cheekbone, Dr Sin Yong usually chooses a calcium hydroxylapatite or polycaprolactone product for its firmer structural behaviour. The volume restoration page sets out the materials and the hollow cheeks page explains how deflation is distinguished from descent with older photographs: the same outline sitting lower means lifting, a changed and emptier outline means volume.

For diffuse loss across the whole mid-face and temples, which becomes common from the mid-40s, a collagen biostimulator such as Sculptra or Ellansé is considered. These do not fill a line the way hyaluronic acid does; they provoke the skin into building its own collagen gradually where they are placed, so the aim is the same face with more structure rather than a changed one. The honest caveat is stated first: they cannot be dissolved, so the placement and the amount are conservative, staged and reviewed, and they are not used in a face where the main problem is descent. Where earlier biostimulator has been placed too generously, Time Freeze Laser LCLR® and VF Lift – Vertical Facelift are built to target that overfill and take away the excess, which is a reason to bring records of any earlier treatment.

Where any earlier filler is involved, ultrasound mapping distinguishes filler from fat before correction, because the two feel alike and are treated differently. Every injection is performed by Dr Sin Yong after examination, and the dermal filler aftercare and Sculptra aftercare pages set out what follows.

The under-eye: hollow, bag, shadow or skin?

Tired-looking eyes in the 40s have four possible causes, and the reflex answer, filler, suits only one of them. A hollow at the tear trough, with good skin over it, can be refined with a small amount of hyaluronic acid placed after the cheek has been assessed, because a hollow under the eye is often the top edge of a deflated cheek. A bag is fat pushing forward through a weakened septum and is not improved by adding volume beside it; the eye bag page explains the options, including when a surgical referral is the honest answer. Dark circles that are pigment or thin skin showing the vessels beneath are a pigment or skin-quality problem, assessed on the dark eye circles page.

Crepey skin and fine lines under the eye are the fourth group, and here filler makes things worse: the skin is the thinnest on the face, and volume under a crepey surface shows as a ridge or puffiness. These lines are treated in the skin, with monopolar radiofrequency such as Thermage for the eyes, a fractional laser at conservative settings, or a skin booster, as the under-eye lines page describes. Hooded upper lids, which become noticeable in this decade as the brow settles, are assessed separately as a brow, lid or skin problem; the droopy eyelids page covers that.

Skin: sun spots, texture and the neck's first lines

Sun spots arrive in this decade as the account of two decades of Singapore ultraviolet comes due: discrete, sharply bordered brown spots on the cheeks, temples and the backs of the hands. Correctly diagnosed, they are the discrete pigment a pico laser is designed to target; the diagnosis matters because melasma, which looks similar and is still common in the 40s, responds almost oppositely, and a new, changing or irregular spot is examined with a dermatoscope before any laser. The sun spots page explains how they are separated from melasma and from the age warts that follow in the next decade.

Texture coarsens as collagen falls and pores lose the support around them, and old acne scars that were ignored in the 30s often become more visible as the skin thins over them. RF microneedling, with its insulated needles delivering heat into the dermis while sparing the surface, suits texture and pores in Asian skin, and fractional CO2 resurfacing, the S3 Resurfacing Lift on the DEKA SmartXide Tetra Pro, is reserved for established scars and texture where the pigment risk is worth it; the uneven texture and pores page sets out how the two are chosen. Dullness that is really diffuse pigment is approached with a laser at toning settings, and skin quality with a skin booster rather than a filler.

The neck is included in the examination from this decade on, because it ages faster than the face it carries: thinner skin, fewer oil glands, less sunscreen and thousands of movements a day. The first horizontal lines and the first crepiness are skin problems, treated with boosters and energy rather than filler, and true laxity of the neck is a lifting question for later; the ageing neck page separates the three.

Which concern goes to which page, and how a plan is made

Aftercare in broad terms

After energy-based lifting, tenderness, mild swelling and occasionally a small bruise are expected and settle; sun protection continues, and strenuous heat such as saunas is deferred as advised. After filler, swelling and bruising settle, pressure on the area is avoided, and the warning signs that need same-day review, skin turning white or dusky, pain that is getting worse or any change in vision, are explained before you leave, with the complication care page as the reference. After a biostimulator, massage instructions are followed as given. The Thermage, dermal filler and thread lift aftercare pages carry the specifics.

How a plan is made

The first visit is an examination of the face in three layers, skin, volume and laxity, with the neck, a history that includes medicines that change bruising, earlier treatments and photographs from your 30s at a similar angle, and ultrasound where earlier filler is involved. A written plan follows, usually in the order lifting, then volume, then surface, staged, and it can include waiting. Fees depend on the layers and areas treated, the protocol or product and the amount the anatomy needs, and how the plan is staged; a written quote follows the consultation.
