What age to start botox — a dermatologist's honest take

'When should I start botox?' has two honest answers — and neither is a specific age. It comes down to what your face is doing: dynamic lines that disappear when you relax, or static lines that are starting to stay.

Late 20s — if lines vanish when you stop moving, this is preventative

Small doses every 6–12 months stop dynamic lines from etching in. Think of it as brushing your teeth. Especially relevant if you have strong habits — a heavy frown, a constantly-raised brow, or you squint at screens all day.

Mid 30s — early corrective

If the line stays visible when your face is at rest, you've crossed from dynamic to early static. At this point botox both relaxes the muscle and softens the existing engraving. Combined with retinoids and daily SPF, this is where the return on investment is highest.

40s and beyond — botox plus collagen work

Deeper static lines don't respond to muscle relaxation alone. You need collagen-stimulating treatment alongside — microneedling, GFC for volumising, skin boosters, or HIFU for lift. Botox alone at this stage often disappoints.

Don't start if

You're under 25 without a specific indication (strong genetic lines showing early, hyperhidrosis, migraine treatment). Pregnancy or breastfeeding — wait. Any unclear muscle or neurological condition — discuss with your doctor first.

Philosophy, not just dose

At Uncover we under-treat on session one and add at the 2-week review. Natural is always better than frozen. If you leave a clinic looking like you can't raise your eyebrows, they used too much.
