Authorised Independent Nu Skin Distributor

You've sorted your general skincare routine — cleanser, toner, serum, moisturiser — and your overall complexion is in decent shape. But every morning, under the bathroom light, those lines around your mouth and eyes stare back: the creases that deepen every winter when central heating dries the air, the crow's feet that office air-conditioning never helps, the nasolabial folds that settled in permanently somewhere around your mid-thirties. A full-face serum spreads its actives thin. ageLOC Tru Face Line Corrector (£42.00) is the precision layer that concentrates a targeted peptide complex exactly where expression lines are deepest — not across your whole face, but on the specific zones that bother you most.
This is not a full-face serum with a clever name. Line Corrector operates on a different principle: instead of spreading actives evenly across the entire facial surface, it deposits a concentrated peptide formula directly onto individual expression lines — crow's feet, nasolabial folds, lip lines, under-eye creasing. The dose at any given line is materially higher than a whole-face serum applied at the same spot.
Specifically selected to target the visible appearance of established expression lines — not just fine surface wrinkles, but the deeper creases that develop from years of repeated facial movement. These peptides support the skin's natural repair processes in the treated zones, working to plump and smooth the appearance of lines over consistent use. The cumulative benefit builds over four to eight weeks of twice-daily application.
Nu Skin's proprietary ageLOC technology targets gene expression clusters associated with visible ageing signs. In Line Corrector, this complements the peptide complex's targeted action rather than acting as a standalone ingredient — the two work in concert on the specific zones of application.
Provide an immediate, same-day optical softening effect from first use. Lines look visibly softer within minutes of application. This effect is cosmetic and temporary — it lasts through the day — but it sits cleanly under moisturiser, primer, and foundation without pilling, tackiness, or interference with makeup wear. Relevant if you're applying foundation over crow's feet or concealer under the eyes as part of a daily routine.
The serum texture absorbs quickly and doesn't disrupt the products layered above it. This matters particularly around the mouth and eye areas, which are in near-constant movement throughout the day. There's no residue that causes mascara to migrate or lipstick to bleed.
| Product | Targeted Zone | Formulation Approach | Peptide Delivery | Immediate Effect |
|---|---|---|---|---|
| ageLOC Tru Face Line Corrector | Eyes, mouth, nasolabial folds — precision zones | Concentrated peptide complex + ageLOC blend + smoothing polymers; applied directly to individual lines | High local concentration at the application site; not diluted across the full face | Immediate optical smoothing via polymers; cumulative peptide benefit over 4–8 weeks |
| Boots No7 Restore & Renew Multi Action Serum | Full face — swept across entire surface | Matrixyl 3000 peptide blend in a general hydrating base; broad coverage rather than precision placement | Diluted across full face; lower local concentration at any individual line | Mild; no dedicated line-filling polymer system |
| Elemis Pro-Collagen Eye & Lip Contour Cream | Eye and lip contour — closer zone match | Marine collagen and botanical extracts; cream texture rather than serum; no specific gene-expression technology | Indirect collagen support via marine extracts; no dedicated signalling peptide complex | Moisturising and softening; no dedicated optical line-filler |
| The Ordinary Argireline Solution 10% | Expression lines — single-peptide approach | Single peptide (acetyl hexapeptide-3) at 10% in aqueous base; no complementary ageing-gene technology or polymer system | One peptide mechanism only; no synergistic ageLOC blend | Some immediate muscle-relaxing-like surface effect; no dedicated smoothing polymer |
Comparison highlights formulation approach and ingredient delivery differences only. No "better/worse" verdict is implied.
Apply a small amount directly to expression lines around the mouth and eyes, morning and evening. Use your ring finger — it naturally applies the least pressure — to pat the product gently into the skin. Do not rub or drag, particularly around the delicate eye area. Layer underneath your regular moisturiser or eye cream.
For best results within the Tru Face system: apply Refining Toner first, then Line Corrector on targeted areas, then your full-face serum (Future Serum or Essence Ultra), then moisturiser. Line Corrector goes on before your serum because it needs direct contact with the specific lines being treated — if the serum goes on first, the peptide complex cannot reach the skin surface at the line.
A mild immediate smoothing effect is visible from the first application — lines appear slightly softer right away due to the smoothing polymers. Cumulative results from the peptide complex build over four to eight weeks of consistent twice-daily use. Deep-set nasolabial folds will not disappear — no topical product can achieve that — but their visible depth can be softened. Around the eyes, where skin is thinner and lines shallower, results tend to show sooner. Individual results vary.
Yes — Line Corrector is stocked and ships from the Nu Skin UK warehouse. Standard delivery is typically 2–4 business days to addresses across England, Scotland, Wales, and Northern Ireland. As the UK is outside the EU single market post-Brexit, no EU duties apply to UK domestic orders.
Both. Line Corrector is a precision treatment for specific zones — crow's feet, nasolabial folds, lip lines — not a substitute for a full-face serum. Apply it directly to targeted lines before your full-face serum. The two products address different scales of concern: Line Corrector concentrates actives at specific lines; your serum addresses overall facial skin quality.
The formula is a lightweight serum designed to work under moisturiser rather than replace it. If your skin is dehydrated — a common concern across London and the South East, where hard water mineral deposits and low-humidity office environments strip moisture — apply Line Corrector to targeted lines and follow with your usual moisturiser. The smoothing polymers will not exacerbate dryness, and the peptide complex does not require a compromised skin barrier to work, though a healthy barrier always supports better ingredient absorption.
The smoothing polymer system in the formula is specifically designed to create a smoother surface for products applied on top. It does not pill, does not feel tacky, and does not cause foundation to separate — which is particularly relevant around the mouth and eye zones where movement is constant. Allow approximately 60 seconds for the serum to absorb before applying moisturiser, primer, or foundation.
Yes — Line Corrector and an eye cream serve different functions. Apply Line Corrector directly to crow's feet or under-eye creasing first (using your ring finger, patting rather than rubbing), allow it to absorb, then apply your eye cream over the top. For the eye area specifically, consider pairing with ageLOC LumiSpa iO IdealEyes for a complementary brightening and firming benefit.
Yes. As a cosmetic product sold in the UK, ageLOC Tru Face Line Corrector is subject to the UK Cosmetics Regulation (retained EU law, enforced post-Brexit in Great Britain). This requires safety assessment, a responsible person registered in the UK, and compliance with ingredient restrictions. The product is sold through Nu Skin's UK-registered entity. This is a cosmetic product, not a medicine, and it is not regulated by the MHRA as a medicinal product.
Because Line Corrector is applied precisely to targeted lines rather than spread across the whole face, a small amount is used per application. Most users applying to crow's feet and nasolabial folds twice daily find a single bottle lasts approximately four to six weeks — conveniently aligned with the typical timescale for peptide-driven cumulative results to become visible.
