Whether you have natural lashes, a lift, extensions, a tint, lamination or microblading — UV is working against you every time you go outside. This serum is the only product in the world designed to stop it.
We all know UV damages skin. Almost nobody knows it does the same to lash and brow hair — breaking down proteins, stripping moisture, bleaching colour, and undermining every treatment you invest in. Sun damage is one of the primary causes of lash breakage and brow thinning.
Even on cloudy days, UVA passes through cloud cover and continues to damage lash and brow hair. Daily protection isn’t seasonal — it’s year-round.
Three sections of the same hair — one bare, one with a generic serum, one with Sun Protect Serum — were exposed to 8 hours of UV and examined under an electron microscope.
The bare and generic serum sections showed significant UV-related surface damage. The Sun Protect section appeared completely undamaged — smooth, intact, and indistinguishable from its pre-UV state.
“Two of the best beauty products I have ever invested in — in terms of results, you have to use them for a few weeks, but the results from there are undeniable.”
A trichotillomania (compulsive hair pulling) sufferer for several decades. Using the Lash Growth Treatment for 13 years, now adding the Sun Protect Serum: “The Opti Laboratories serum has completely resolved this. The LVL effect lasts longer — I am still feeling the benefits 9 weeks after my last treatment.”

The deeply conditioning qualities of the serum mean not only do the lashes stay hydrated and keep their form, the LVL effect lasts longer, I am still feeling the benefits of it 9 weeks after my last treatment.”

The formula isn’t just a UV filter — it’s a full conditioning and growth-supporting treatment in a single daily step.
Sulisobenzone — the UV shield
Absorbs, reflects and scatters UV rays before they can break down the proteins in your lash and brow hair. The core protective ingredient.
Growth promoter
Stimulates IGF-1 (a growth factor) in the hair follicle and suppresses TGF-B (which shortens the growth cycle) — resulting in a longer, more productive growth phase.
Keratin booster + anti-inflammatory
Increases keratin in the hair shaft, prolongs the growth cycle, and reduces follicular inflammation that can inhibit growth.
Multi-pathway growth activator
Ginsenosides activate growth pathways, inhibit the signals that end the growth cycle, and improve local blood flow — supporting stronger, longer hairs.
Anti-inflammatory antioxidant
Reduces inflammation around the follicle and neutralises free radicals — supporting healthy hair growth from the root up.
Vitamin E — free radical scavenger
Mops up free radicals generated by UV exposure before they can damage hair proteins. Also activates follicle growth pathways directly.
Preserves the curl by protecting disulphide bonds from UV oxidation.
Protects adhesive bonds and reduces premature shedding.
Protects the polymers holding your lamination in place.
Locks in colour and prevents brown tones going orange.
Protects structure, moisture and length from daily UV damage.
Locks in colour and prevents lashes fading.
Whether you spend £30 on a tint or £150 on extensions — the serum that protects every appointment costs £59 for three months.
Apply daily as the last step of your morning routine — after serums, before mascara or brow pencil. Apply from the day of any lash or brow treatment to protect the result at its freshest.
Pair with the Lash Growth Treatment for complete 24-hour lash care.
