Your chest ages like your face, with less to heal with.

Intense pulsed light treats the two components of poikiloderma at once, which is why it became the standard. In the first large series, 135 patients with typical changes on the neck or upper chest received one to five treatments and cleared more than 75% of the telangiectasia and hyperpigmentation, with side effects, including pigment changes, in 5%, and many noting smoother texture (135-patient IPL series); in the seven-year Italian series, 175 patients of skin types I–III averaging 49 years had three sessions three weeks apart and cleared more than 80% of the vascular and pigmented components, with minimal transient side effects in 5% and no scarring or pigment disturbance (175-patient IPL series). Biopsies from 14 necks after three monthly sessions showed more homogeneous melanin, more fibroblasts and unfragmented elastic fibres and denser, thicker collagen bundles, with clinical improvement in 93% (IPL histology study). The systematic review of IPL rates the poikiloderma evidence level 3 — series, not trials — against level 1 for telangiectasia and melasma (IPL systematic review). Moderate: 310 consistent patients and no control group. The laser guide covers settings and the reasons darker and tanned skin are excluded; the sunscreen row decides whether it lasts.

Vascular lasers target the vessels that make the red half of poikiloderma. In a blinded study of a redesigned pulsed-dye laser with a 15 mm spot and 50% higher energy, 17 patients completed four monthly treatments: three blinded raters correctly identified the baseline photograph in 94% of comparisons, 14 of 17 improved by more than 40% and 10 by more than 50%, the average improvement was 49%, and side effects were mild swelling, redness and purpura with pain of 3.5 on an 11-point scale (pulsed-dye study). A 2025 study of a long-pulse 532 nm laser with cryogen cooling treated 20 people four times and found average improvement of 74% on the neck and 68% on the chest two months later, with redness, swelling and purpura the only side effects (532 nm study), on the back of an older KTP series (KTP series). The caution is the older series: eight patients treated with a 585 nm pulsed-dye laser at 450 microseconds cleared their vessels, and the six treated at 5–7 J/cm² reported severe depigmentation four to eleven months later while the two at lower fluence did not (depigmentation series). Moderate: blinded but small and uncontrolled. Fluence as low as works, a test patch reviewed at three months, and an operator who treats chests weekly.

Non-ablative fractional lasers heat columns of dermis without removing the surface, which on adnexa-poor skin is the difference between resurfacing and scarring. The 1927 nm thulium wavelength, absorbed strongly by water in the upper dermis and epidermis, has the chest's only randomised trial of a laser on its own: twelve Danish women with moderate-to-severe décolleté photodamage had their chests divided into four areas randomised to a single thulium treatment, photodynamic therapy, both, or lesion-directed curettage alone, and at twelve weeks the thulium-treated areas had improved overall photodamage, mottled pigmentation and wrinkles against the control area, with the combination no better than thulium alone except for texture (thulium décolleté trial). The pilot before it treated nine people with non-facial photodamage three times and a blinded assessor rated mean improvement 3.25 on a 0–4 scale for photodamage and 3.33 for lentigines, with no scarring or pigment disturbance (thulium pilot). A gentler low-power 1440/1927 nm diode, four sessions a month apart, improved chest wrinkle scores by 0.7, texture by 1.4 and pigment by 0.67 points in the 20 of 24 women who completed (diode chest study), and three sessions of a 1550 nm laser on 19 necks shifted wrinkle scores from severe to moderate and thickened the dermis from 1.15 to 1.30 mm on ultrasound (1550 nm neck study). Moderate: one small randomised trial and consistent small series. The laser guide grades the wavelengths; on the chest the rule is lower density than the face, no tan, and the retinoid paused a week before.

Microfocused ultrasound places lines of thermal coagulation points at 1.5, 3 and 4.5 mm without touching the surface, which suits skin that scars. Its chest evidence is two industry-run studies. In the first, 24 women with moderate-to-severe chest wrinkles on the validated Fabi-Bolton scale had a single treatment and were measured at 90 and 180 days by the scale, by mid-clavicle-to-nipple distance, by masked assessment and by satisfaction: wrinkles improved over time with appreciable efficacy and satisfaction, in a single centre with only skin types I and II enrolled (24-woman study). In the multicentre follow-up, healthy women with moderate-to-severe décolleté lines received 280 treatment lines with three transducers in one session: 77 of the 116 evaluable women (66.4%) showed aesthetic improvement at 180 days on blinded assessment, the clinicians rated roughly 75% improved at 90 days, most were satisfied, and adverse events were generally mild (multicentre study); its registry entry lists 125 treated women of skin types I to IV, none darker (multicentre trial registry). Moderate: blinded photographs, no control group, skin types I to IV only, and the maker's funding. The sagging-skin guide grades the same device on the face and neck, where a randomised trial exists; on the chest the appeal is a single session with no wound on skin that heals badly.

Photodynamic therapy — a photosensitising cream incubated on the skin and activated by light — is a treatment for the field of actinic keratoses that also smooths what it treats. In a randomised, evaluator-blinded split-chest study, women with chest photodamage had three courses over eight weeks, one side pre-treated with a low-energy 1927 nm laser before the photodynamic session: at week 20, all eleven who completed had improved wrinkle scores and ten improved texture on both sides, with no difference between the pre-treated and untreated sides and significantly worse adverse events on the laser-plus-PDT side (split-chest PDT study). In the Danish four-area trial, thulium alone matched the thulium-plus-PDT combination on overall photodamage, with the combination better for texture (thulium décolleté trial). Emerging as a cosmetic treatment; the sun-damage guide grades it strong for the keratoses, which on a photodamaged chest are often the reason it should come first. The chest reviews list it among the standard options (chest rejuvenation review).

Microneedling has the neck's evidence and not the chest's: 35 adults had four monthly sessions with a pen at depths up to 2.5 mm, and two blinded raters found significant wrinkle improvement on the neck at 90 days in the 32 who completed (neck microneedling study). Radiofrequency microneedling, which adds heat at the needle tips, has trials on the face and the lower face and neck but none on the chest, and the microneedling guide grades both. Emerging for this site: a mechanism that transfers, depths and energies that must be lower than the face on a dermis this thin, and no chest data. A reasonable middle rung for crepe in darker skin that the light devices exclude, at a conservative setting, with an operator who has treated chests before.

Chemical peels are listed among the chest options in both reviews (chest rejuvenation review; décolletage review), and the evidence beneath them is borrowed: the double-blind trial of 8% glycolic and lactic acid on face and forearms for mottling and texture (Stiller 1996) and a laboratory study of a professional TCA-lactic peel showing the enzyme and gene changes behind collagen repair and pigment reduction (TCA-lactic peel study). No chest trial exists. Emerging: a course of superficial peels — lactic, mandelic, glycolic or 10–15% TCA — smooths and evens a rough chest modestly, and the medium-depth peels that treat facial crepe are where the chest's thin, adnexa-poor skin scars and depigments. The peel guide covers depths and the darker-skin choices.

Fractional ablative lasers vaporise columns of skin and rely on the surrounding follicles and glands to re-grow the surface — the structures the chest has few of. A chest review permits them — "For more dramatic results, ablative fractional lasers can be safely used, although longer healing times and potential adverse effects are to be expected" — and traces the adverse events to the thin dermis and sparse pilosebaceous units (chest rejuvenation review). The case series show the cost of getting it wrong: five patients treated for neck photodamage with the same fractional CO2 device, at 15–30 mJ where the settings were reported, developed hypertrophic scars on the neck within weeks, while the faces treated in the same session healed (neck scarring series), and a 2016 report describes severe scarring of a 45-year-old's neck after aggressive fractional CO2, with the author's recommended modifications (severe neck scarring report). No chest trial. Emerging on this site — the laser guide grades the same lasers strong on the face — and the last rung: low energy, low density, a test area, winter, fair untanned skin, and an operator whose photographs of chests you have seen.
