What is skin aging?
Skin aging is the gradual thinning and loss of elasticity of the skin with age, along with reduced sebum that leaves it dry and dull. The Asan Medical Center disease encyclopedia explains that these changes begin in the early 30s, starting with loosening of the thin upper eyelid skin and expression lines.
The American Academy of Dermatology divides skin aging into intrinsic aging, whose timing is largely controlled by genes, and extrinsic aging, which environment and lifestyle accelerate. Intrinsic aging cannot be prevented, but extrinsic aging can be slowed with preventive steps.
Why does skin age?
Skin aging results from internal factors such as age and genes together with external factors such as UV light and smoking. UV light is the main cause of photoaging; its extent depends on sun exposure and skin pigment, and the damage accumulates.
Intrinsic aging
Age and aging genes, degeneration of elastic fibers and connective tissue, muscle deterioration, loss of subcutaneous fat, reduced circulation, and decreased sebum and moisture are the causes.
Photoaging
It results from accumulated UV damage, and the American Academy of Dermatology notes that the sun plays a major role in premature aging. UV light is also closely linked to wrinkles, melasma and skin cancer.
Lifestyle factors
Smoking greatly speeds up skin aging, causing wrinkles and a dull complexion, and repeating the same facial expression for years makes those lines permanent. Pollution, dry environments, and harsh cosmetics or soaps are also cited as causes.
What are the signs of skin aging?
Skin aging shows as fine lines and expression lines, loss of elasticity, dryness, enlarged-looking pores, and pigment changes such as spots. As it progresses, nasolabial folds, lines around the nose, crow's feet and forehead lines become noticeable and later spread to the lips and neck.
Wrinkles
They start as fine lines and expression lines around the eyes and forehead and progress to deep folds such as the nasolabial folds.
Loss of elasticity
Elastic and collagen fibers in the dermis degenerate, so the skin loses elasticity and becomes thinner.
Dryness and pores
Less sebum and moisture make the skin dry, and pores look stretched where elasticity has dropped.
Pigment changes
Pigment changes such as spots and melasma increase where UV damage has accumulated.
How is skin aging assessed?
Skin aging is assessed by examining the depth and location of wrinkles, elasticity, dryness, pores and pigment, and deciding which change bothers you most. The Asan Medical Center disease encyclopedia notes that no special tests are needed before a procedure, but that smokers and anyone using medication or topical ointments should consult a doctor first.
Type of wrinkle
Distinguish lines that appear only with expression from deep folds that remain at rest.
Sagging or hollowing
Check whether only the skin surface has changed or whether cheek and jawline sagging or volume loss is also present.
Distinguishing pigmented lesions
What looks like a spot may be a condition such as actinic keratosis or melanoma, so its shape and any change are checked.
How is skin aging treated?
Treatment of skin aging starts with skin care such as sun protection, moisturizer and retinoids, moves to injectable procedures such as skin boosters, skin botox and filler, and steps up to lifting procedures when sagging is also present. The American Academy of Dermatology names sunscreen and moisturizer as the most effective anti-aging products and notes that you cannot get the results of a facelift from a cream.
| Treatment step | Main role | What to consider |
|---|---|---|
| Sun protection and moisturizer | Main roleThe basis of prevention and softening fine lines | What to considerUse daily and reapply every two hours outdoors |
| Retinoids | Main roleManage texture, pigment and mild fine lines | What to considerCan irritate, so start low; not for use in pregnancy |
| Skin Boosters | Main roleManage texture, inner dryness, fine lines and elasticity | What to considerRepeated at intervals of weeks; temporary redness and bruising possible |
| Skin botox and botox | Main roleManage texture and expression lines | What to considerEffect wears off after 4-6 months and does not treat deep wrinkles |
| Dermal Fillers | Main roleRestore volume in hollow areas | What to considerImmediate effect, usually lasting 6 months to 1 year |
| Peels and lasers | Main roleManage pigmented lesions and fine lines | What to considerDeep peels need recovery time, cause redness, and require sun protection |
| Lifting procedures and surgery | Main roleCorrect contours when sagging is also present | What to considerNon-surgical, thread or facelift chosen by extent of sagging |
The Asan Medical Center disease encyclopedia explains that botox and filler work by different mechanisms on different wrinkle areas, and that depending on the location and severity of wrinkles, surgery may be required.
How does Myongji Best Plastic Surgery Clinic manage skin aging?
Myongji Best Plastic Surgery Clinic in Myeongji-dong, Gangseo-gu, Busan first identifies your current concern among texture, inner dryness, fine lines, elasticity, pores and pigment, then chooses what is needed among skin boosters, skin botox, filler and lifting procedures. The number of sessions and intervals depend on the product and skin condition.
Skin Boosters
For texture, inner dryness, fine lines and elasticity, PN (Rejuran), PDLLA with hyaluronic acid (Juvelook), ECM (Re2O) or hyaluronic acid (Hilo Wave) is injected into the dermis. Re2O is recommended 2-3 times at 4-week intervals, and Hilo Wave 3 or more times at 3-4-week intervals.
Skin botox
For fine lines, pores, sebum and elasticity concerns, diluted botulinum toxin is injected in small amounts into the shallow dermis at 1-2 cm intervals. It takes about 10-15 minutes under numbing cream, while standard botox injected into the muscle layer is used to soften expression lines.
Dermal Fillers
Hyaluronic acid filler is injected into hollow or sunken areas to restore volume. The procedure takes about 10-20 minutes under topical or local anesthesia, and results are expected to last about 6 months to 1 year.
Lifting
When the facial line blurs along with loss of elasticity, focused ultrasound Shurink (3 sessions at 3-4-week intervals) or radiofrequency Alltite (3 sessions at 2-4-week intervals) is used, and when sagging is pronounced, thread lift and mini facelift are compared.
How can I slow skin aging with prevention and self-care?
The basics of preventing skin aging are daily sun protection, moisturizing and quitting smoking. The American Academy of Dermatology notes that even people with signs of aging give their skin a chance to repair some damage by protecting it from the sun, and that smokers who quit often notice healthier-looking skin.
Sun protection
Apply a broad-spectrum, SPF 30 or higher, water-resistant product daily to all skin not covered by clothing, and combine it with shade, long clothing, a hat and sunglasses. Tanning accelerates skin aging.
Moisturizing and cleansing
Moisturizer traps water in the skin and makes fine lines less visible. Scrubbing while cleansing and products that sting or burn irritate the skin and accelerate aging.
Retinoids
Start with the mildest product every other night and build up slowly; apply it only at night and protect the skin from UV during the day. Do not use it during pregnancy.
Lifestyle
Quit smoking, drink less alcohol, eat plenty of fresh vegetables and fruit, and cut down on sugary foods. Sunglasses help avoid repeated squinting so the same expression is not reinforced.
Common care after procedures
After skin boosters or skin botox, limit washing and makeup on the day, do not rub the treated area, avoid saunas and strenuous exercise for the advised period, and keep up sun protection.
Which symptoms mean I should contact the clinic right away?
If a spot or mole grows quickly, changes shape or color, or bleeds, it may be a skin condition rather than an age spot and should be examined. UV damage also raises the risk of skin cancer, so new lesions deserve attention on heavily photoaged skin. Swelling, pain, redness and itching after a procedure usually fade within days, but contact the clinic if they persist or other reactions appear.
Treatment steps and responses for skin aging vary with skin condition, wrinkle depth and whether sagging is present, so the medical team sets the plan after an examination.
How much do skin aging procedures cost?
Myongji Best Plastic Surgery Clinic's published non-covered fee list shows Rejuran HB 2cc 450,000 KRW and I 1cc 159,000 KRW, Juvelook Skin 4cc 440,000 KRW per session, Elravie Re2O 6cc 770,000 KRW, Hilo Wave 550,000 KRW, Skin botox Hitox 110,000 KRW per session, Rejuviel 1cc 150,000 KRW, Shurink Universe 300 shots 129,000 KRW, and Alltite 690,000 KRW per session (confirmed October 22, 2026).

Frequently asked questions
At what age does skin aging start?
The Asan Medical Center disease encyclopedia explains that skin aging begins in the early 30s. Early on, the thin upper eyelid skin loosens and expression lines appear; as it progresses, nasolabial folds, crow's feet and forehead lines become noticeable.
What SPF sunscreen should I use?
The American Academy of Dermatology advises applying a broad-spectrum, SPF 30 or higher, water-resistant sunscreen every day to all skin not covered by clothing and reapplying every two hours outdoors. Combine it with shade, long clothing, a wide-brimmed hat and UV-protective sunglasses.
Can I use retinol every day?
The American Academy of Dermatology advises starting with the least-intense retinoid product every other night and building up slowly. Because it makes skin more sensitive to sun, apply it only at night, protect your skin from UV during the day, and do not use it during pregnancy.
Can skin aging be reversed?
The Asan Medical Center disease encyclopedia explains that skin aging itself cannot be stopped. Extrinsic aging can be slowed with sun protection and quitting smoking, signs such as fine lines, laxity and pigment are managed with skin care and procedures, and most products take at least six weeks to three months to work.
