What Actually Keeps Skin Looking Younger
Diet, sun protection, hydration, exfoliation and clinical treatments each do something different for skin. This sets out what each contributes and where fat grafting fits.
Most of what determines how skin ages is not clinical. Sun exposure, diet, hydration and sleep do more of the work than any single treatment. This sets out what each contributes, and where clinical intervention adds something the rest cannot.
Diet
Antioxidants combat oxidative stress and neutralise free radicals, which contribute to skin ageing. Foods rich in antioxidants support the skin’s natural repair processes.
Berries such as blueberries, strawberries and raspberries contain vitamins C and E. Leafy greens such as spinach and kale are sources of lutein and zeaxanthin. Nuts and seeds — almonds, sunflower seeds — contain vitamin E and selenium, which support skin elasticity. Avocados and olive oil supply monounsaturated fats. Green tea provides catechins, which have been associated with improved skin hydration and elasticity.
Sun protection
Consistent sunscreen use is the single most effective measure available. Ultraviolet radiation is a major cause of premature skin ageing. Daily sunscreen reduces the development of fine lines, wrinkles and pigmentation.
Choose broad-spectrum protection with an SPF of at least 30, covering both UVA and UVB. UVA contributes to skin ageing; UVB causes burning. Both are associated with skin cancer.
Apply daily, including on cloudy days and indoors near windows — UV penetrates glass and cloud cover does not block it entirely. Apply generously to all exposed skin, including the neck, ears and the backs of the hands, and reapply every two hours when outdoors, particularly when swimming or sweating.
This is a year-round measure, not a summer one.
Hydration and moisturisation
Well-hydrated skin appears plumper and smoother. Adequate water intake supports this from within.
Applying a moisturiser matched to your skin type matters. Oily skin benefits from a lightweight non-comedogenic product; dry skin from a richer cream-based formulation. Look for hyaluronic acid, which attracts and retains moisture, and glycerin, which helps hold it. Applying moisturiser to damp skin immediately after cleansing improves its effect.
Facial oils such as argan or jojoba can add a further layer of hydration and approximate the skin’s own oils.
Exfoliation
Exfoliation removes dead skin cells that dull the complexion and block pores. It also improves the absorption of other products applied afterwards.
Choose the exfoliant appropriate to your skin. Sensitive skin does better with a gentle chemical exfoliant such as an alpha-hydroxy acid or beta-hydroxy acid. Mechanical exfoliants with fine grains can suit normal or oily skin. Two to three times a week is usually sufficient — more than that is counter-productive. Follow with a moisturiser.
Clinical treatments
Clinical treatments offer more targeted intervention than home care.
Microdermabrasion exfoliates the skin to remove dead cells and encourage new cell growth, improving surface texture.
Chemical peels apply a chemical solution to remove damaged outer layers of skin, improving texture and tone. Recovery time varies with the depth of the peel.
Laser treatments use focused light to target specific concerns such as pigmentation and scarring, and stimulate collagen production. Results develop over time rather than immediately.
Injectables — botulinum toxin relaxes the muscles that produce dynamic wrinkles; dermal fillers add volume where it has been lost.
Fat grafting
Fat grafting transfers fat from one area of the body, such as the thighs or abdomen, to areas where volume has been lost — commonly the face. It restores volume using the patient’s own tissue rather than a synthetic product.
Because the transferred fat comes from the patient’s own body, immunological rejection is not a concern. Some of the transferred volume is reabsorbed; the proportion that establishes a blood supply persists.
The procedure is typically performed under local anaesthesia with limited downtime. Swelling and bruising are expected and usually settle within a few weeks.
Assessment determines whether a patient has adequate donor fat and whether the skin quality is suitable.
Stress and sleep
Cortisol released under stress increases oil production and contributes to the breakdown of collagen and elastin.
Mindfulness and meditation reduce anxiety and, over time, cortisol levels. Physical activity releases endorphins and improves circulation. Sleep is significant — poor sleep increases stress and affects the skin’s overnight repair. Aim for seven to nine hours.
A balanced diet including antioxidants and omega-3 fatty acids reduces inflammation.
Questions patients ask
How long do the results of fat injections typically last?
Results can last several years, but this varies. Some of the transferred fat is reabsorbed over time, and further sessions are sometimes needed.
Can an antioxidant-rich diet reverse existing skin damage?
Diet cannot reverse established damage, but antioxidants reduce oxidative stress and support the skin's repair processes.
What SPF level is recommended for daily sunscreen use?
Use broad-spectrum protection with an SPF of at least 30, applied daily and reapplied every two hours during prolonged sun exposure.
How often should I exfoliate?
Two to three times a week is sufficient for most skin. Sensitive skin requires less frequent exfoliation.
The procedure this relates to
Fat is harvested from one part of the body by liposuction, filtered, and reinjected where volume is needed. Because the graft is the patient's own tissue, a proportion of it is reabsorbed in the months after treatment.
