How to Read Botox
Before and After Photos

Botox before and after photos are genuinely useful — and easy to misread. The same lighting issue that applies to filler photos applies here: harsher light in the “before” makes every line more visible. Softer light in the “after” smooths everything regardless of treatment. Same rule: consistent lighting, same angle, no difference in expression.

The other issue is timing. Day 2 botox photos don’t show the result — they show early onset, which looks uneven because different muscles respond at different rates. The real result is at day 10–14 when everything has settled. Any clinic showing dramatic transformations labeled “3 days after” is either showing the wrong measurement point or adding filters.

Results by Area —
What Changes and When

Each area has a different response rate, result type, and duration. Here’s what patients at Yaan Clinic consistently report.

• Forehead lines before and after

  Before: horizontal lines visible with any upward expression, possibly visible at rest in older patients. After (day 10–14): lines significantly softer with expression, nearly invisible at rest. The forehead still moves — just less dramatically. Result lasts 3–4 months. Patients who return consistently before movement fully returns often develop progressively smoother foreheads over time as the muscle weakens slightly with regular treatment.

• Frown lines (11 lines / glabella) before and after

  Before: vertical lines between brows at rest or with concentration. After (day 10–14): lines significantly reduced or eliminated. The glabellar muscles are strong — this area responds reliably to botox and often shows the most dramatic improvement. Static lines (present at rest) improve with treatment but may not fully disappear — depth of static lines reflects accumulated damage, not just muscle activity.

• Crow’s feet before and after

  Before: fan-shaped lines at outer eye corners with smiling. After (day 10–14): lines significantly softer, eye area looks fresher. One of the most reliable botox results — the orbicularis oculi responds consistently and quickly. The eye still smiles; the lines just don’t fan out as deeply. Duration 3–4 months. Patients often notice this as the area that makes them look most “refreshed.”

• Botox eyebrow lift before and after

  Before: brow tail sits heavy, eyes appear hooded or tired. After (day 10–14): brow tail elevated 1–3mm, eyes appear more open. Achieved by relaxing the lateral depressor muscles (orbicularis) that pull the brow down, allowing the frontalis to lift unopposed. Technique-dependent result — placement matters significantly. Not a replacement for surgical blepharoplasty in advanced hooding, but meaningful for early-to-moderate brow descent. See Post 01 for mechanism →

• Masseter jaw slimming before and after

  Before: square lower face, prominent jaw angle, wide appearance from the front. After (week 8–12): visibly slimmer lower face, softer jaw angle, V-line effect. The result takes longer than wrinkle botox because muscle atrophy is a gradual process. Initial relaxation at 2–3 weeks; visible volume reduction at 6–8 weeks; peak slimming at 3 months.

The Full Timeline —
Day by Day

• Day 0

  Injection — no visible change yet

  Mild redness and occasional small bumps at injection sites resolve within 2–4 hours. Some patients notice the first subtle reduction in movement by end of day — most don’t. Normal activity resumes immediately. Avoid rubbing the treated area for 4 hours, intense exercise for 24 hours.

• Day 1–3

  Early onset — partial, uneven effect

  Some muscles begin relaxing earlier than others. The result looks uneven at this stage — one side may appear to have responded more, or movement is partially reduced rather than smoothed. This is not asymmetry from the injection; it’s the natural progression of botox onset. Don’t judge the result here.

• Day 5–7

  Main effect settles in

  Most of the botox effect is now present. Lines are visibly softer, movement is reduced. Still not the final result — some further settling happens over the next week. Patients who check at day 7 usually feel reassured at this point even if they were anxious earlier.

• Day 10–14

  Full effect — assess here

  The final, settled result. This is the correct comparison point for before and after photos. Any residual asymmetry visible here is the actual outcome — not an artifact of the settling process. At Yaan Clinic, patients contact via WhatsApp at day 14 with comparison photos if they have concerns. Touch-ups, if needed, are assessed from this baseline.

• Month 3–4

  Movement returns — plan maintenance

  Acetylcholine release gradually resumes as nerve terminals regenerate. Movement starts returning, lines become slightly visible again. The ideal maintenance window: return before full movement is back — this keeps results more consistent and may reduce the units needed over time. Most patients at Yaan Clinic return at the 3–3.5 month mark.

What Botox Can’t Do —
Setting Realistic Expectations

Botox works on dynamic wrinkles — lines created by muscle movement. It doesn’t work on everything people sometimes expect it to.

Frequently Asked
Questions

What do botox before and after results actually look like?

Subtle and natural — not frozen. Forehead lines softer with expression, frown lines less prominent, crow’s feet reduced. The face still moves; wrinkles from movement are less deep. Results look like a more rested version of yourself. The change is most visible in comparison photos taken at day 14 under identical lighting.

How long until botox results show?

First visible relaxation at day 3–5. Full effect at day 10–14. Day 1–2 photos don’t represent the final result — don’t assess before day 14. For masseter jaw, visible slimming appears at 6–8 weeks as the muscle gradually atrophies.

What does botox eyebrow lift before and after look like?

Brow tail elevated 1–3mm, eyes appearing more open and less hooded. The change is subtle but meaningful — more visible in side-by-side comparison photos than in the mirror. Achieved by relaxing the lateral depressor muscles that pull the brow down. Technique-dependent result — placement precision matters significantly.

How long does botox last?

Forehead, frown lines, crow’s feet: 3–4 months. Brow lift: 3–4 months. Masseter jaw: 4–6 months. Chin, DAO, perioral: 2–3 months. Skin Botox: 2–3 months. Individual metabolism affects all timelines. Returning before full movement is back helps maintain consistency. For cost per session, see Post 03: Cost & Pricing →

What areas does botox work best for in Korea?

Most consistent results: forehead lines, frown lines/11 lines, crow’s feet, and masseter jaw slimming. Brow lift and perioral are technique-dependent with more variation. Skin Botox for pore and texture improvement is a Korean specialty. For the complete jaw slimming guide, see Post 04: Jaw Slimming →
