More nail treatment than traditional base coat. The formula uses AHAs and vitamins to exfoliate, hydrate, and reinforce the nail plate, targeting nails that have been weakened by gel manicures or are prone to splitting and breakage.
Works as a two-in-one: you can wear it alone as a standalone nail strengthener treatment, or use it as a base coat under regular (non-gel) nail polish.
Designed as a short-term treatment course rather than everyday wear. The recommended approach is twice-weekly application over a few weeks to help nails recover, then as-needed for maintenance.
Manucurist is a French brand that formulates all its nail products around a blacklist of nine common nail polish chemicals. The S.O.S. base coat is part of their broader non-toxic nail top & base coats and treatment line, made with a largely plant-derived formula.
No need to remove the previous coat before reapplying. You can layer new coats directly over old ones during the treatment period, which simplifies the routine if you're using it multiple times a week.

Pros

Good coverage with most colors; one person got full opacity in a single coat, and others needed only two.
Lasts well once on; one person went 14 days with heavy hand use before seeing chips, and others reported a week or more.
The brush is wide, making application easier for most colors.
Applies smoothly for most shades and dries within about 20 minutes.

Cons

Colors often look different in person than in the product photos; multiple people received shades lighter or more muted than expected.
Formula consistency varies by shade; a few colors are thin and streaky, requiring four or more coats.
Drying time feels long to some people, especially with multiple coats.

A 2-in-1 formula that works as both base coat and top coat: applied before color to help it adhere, then again after color to seal and add shine.
85% of the formula is plant-based, derived from sustainably sourced cotton, sugarcane, and corn. Essie defines "naturally derived" as ingredients retaining more than 50% of their molecular structure from plant or mineral sources.
Goes on clear, so it works with any nail color in your rotation rather than being paired to a specific polish line.
Most base and top coats are separate bottles. As a non-toxic nail top & base coats option, this consolidates both steps into one product, which simplifies the process but means you can't optimize each layer independently.
Filled in a carbon-neutral factory, and the bottle itself is the lightest essie has made, designed with recycled materials.

Pros

Dries noticeably fast; most people report being touch-safe within a few minutes, though not quite the advertised one minute.
Adds a high-gloss shine that stays visible for days.
One person found their manicure lasted weeks with minimal wear, and several others reported multi-day chip resistance.

Cons

The formula gets gloopy partway through the bottle, requiring you to wipe excess off the brush before applying.
A few people experienced chipping or full peeling within one to two days.
Drying time claims are overstated; the surface sets quickly but the polish underneath can still dent or smear for a while after application.

A quick-dry top coat that goes over your color polish to speed up drying time and add a glossy, shiny finish.
Designed to take wet polish to dry in under a minute, which makes it useful if you tend to smudge your nails waiting for them to set. Note that nails aren't fully cured for a couple hours even with a fast-dry top coat.
Goes on clear and works as the final step over any nail polish color, not just essie shades, though it's formulated with essie's system in mind.
As a non-toxic nail top & base coats option, it uses a relatively short ingredient list of nine components to deliver the quick-dry and shine effects.
Essie has been around since 1981 and formulates its entire line as vegan. The brand started in the salon world, which is where its base coat/top coat system approach comes from.

Natural UV-sensitive photoinitiators react to natural UV light, allowing the top coat to dry faster than a classic top coat without curing under a lamp.
It leaves a gel-effect mirror shine, with the high-shine finish lasting for up to a week.
Made for the final step of a Green manicure, it protects the color and adds three more days of staying power to nail polish.
The protective finish holds up against hand sanitizer, making it suited to manicures that face frequent hand cleaning.

Performance score

Where to buy

Amazon

Pros

Adds a glossy, salon-like finish that noticeably elevates the look of gel nail strips.
Multiple people found their gel strips lasted two weeks or longer with the top coat, compared to about one week without it.
Helps prevent chipping on high-use nails like pointer fingers by adding a hardened layer over the strips.
Evens out the texture of strips for a smoother overall appearance.

Cons

The bottle is small relative to the price, though one coat per set helps stretch it.
Getting a thin, even coat can be tricky; one person found it dried brittle and cracked off within a day, taking some of the strip with it.
Instructions are unclear on exactly how to apply it over nail strips, particularly around the edges.

Ohora's gel top coat is designed specifically as a companion to their semi-cured gel nail strips, applied after the strips are in place and then cured under a UV lamp to seal everything together.
The formula goes on without clumping or dripping, and the included DuPont brush (220 bristles at 2.5mm) is meant to spread gel evenly in streak-free coats.
Requires a UV/LED gel lamp to cure, so this isn't a traditional air-dry top coat. If you're already using ohora's gel strip system, the lamp is part of that workflow.
As a non-toxic nail top & base coats option, ohora's formula is vegan and produced in-house, where the brand manages its own quality control rather than outsourcing manufacturing.
Primarily useful for extending the wear and adding a glossy, hardened finish to semi-cured gel strips. It works on both manicures and pedicures.

Strengthen & Breathe Oxygenated Base Coat and Nail Strengthener

Dual-purpose product: works as a base coat under polish to improve adhesion and extend wear, or on its own as a nail strengthening treatment. It uses a patented hardening agent to reduce brittleness and splitting.
The formula is "oxygenated," meaning it forms a water-permeable film that allows air and moisture to pass through to the nail rather than sealing it off completely. Most conventional base coats create a fully sealed layer.
Finishes semi-sheer with a milky white tint, so it's subtle enough to wear on its own for a minimal, natural look.
Particularly useful if your nails are dry, prone to peeling, or tend to break easily. It's a non-toxic nail top & base coats option that doubles as a conditioning treatment between manicures.
Nailberry's L'Oxygéné line is 83% naturally derived and formulated to meet Halal guidelines, which means no alcohol or animal-derived ingredients in the formula.

Part of L.A. Colors' Salon Fabulous Nail Treatments line, this is a gel-finish top coat meant to go over regular nail polish to add a high-shine, gel-like look without requiring a UV or LED lamp.
Designed to extend the life of a manicure while intensifying the color underneath, so it pulls double duty as both a shine booster and a protective seal.
Goes on clear with a glossy finish. The formula is gel-style in appearance but applies and removes like a conventional non-toxic nail top & base coats product.
L.A. Colors sells this at drugstore-level pricing (around $4 from the brand directly), which puts it well below most salon-branded gel top coats.

The gel texture forms a protective shield over a Green Flash manicure, leaving a plumped, glossy, radiant gel finish with wear lasting up to 21 days.
Removal is a peel-off process that takes 10 minutes and does not require filing or acetone.
It cures dry and resistant under an LED lamp, with no wipe needed after curing. The precision brush is intended for an even application.
This top coat works exclusively within the Green Flash system, including its base coat, colors, lamp, and remover; it is not suitable for Green, Active, or other brands.

Pros

Applies smoothly and reaches full opacity in two coats across multiple shades.
Dries in roughly five minutes, which makes at-home manicures faster.
With a base coat and top coat, wear consistently reaches about a week for most people; one person reported up to 10 days.

Cons

Chips quickly without both a base coat and top coat; one person saw chipping within 14 hours even with a full prep routine.
Some shades look noticeably different in person than in product photos, running darker or more muted than expected.
Has a strong chemical smell that one person found surprising given the formula's positioning.

Part of Sally Hansen's Good. Kind. Pure. line, this top coat is designed to seal color from the same collection, adding a glossy finish over your manicure.
Plant-based and vegan formula, paired with a brush made from natural, plant-based bristles rather than synthetic ones.
Goes on clear and works like a traditional top coat: one layer over dried polish to lock in shine and extend wear.
As a non-toxic nail top & base coats option, it fits into the same 16-free framework as the rest of the Good. Kind. Pure. range, skipping a longer list of common polish chemicals than most drugstore alternatives.

How to Swap to Non-Toxic nail top & base coats:

Here's how to swap to non-toxic nail top & base coats:

What to know about nail top & base coats

Top and base coats sit directly on your nails for days at a time, which means what they're made of matters. Welpr looks at the full ingredient list for solvents, resins, and other components that may be linked to hormone disruption, allergic reactions, or respiratory irritation.

Labels like "10-free" or "21-free" have no standard definition, so Welpr reads every ingredient list instead of relying on marketing claims.
Because these products stay on your nails continuously, they deserve more attention than products you rinse off quickly.

Review what you already use

Grab the top and base coats you currently use and check them with the Welpr Personal Care and Cosmetic Scanner. The scanner reads your ingredient label and flags anything that doesn't meet Welpr's standards.

Start with the coat you use most often — if you apply a top coat every few days for touch-ups, check that one first.
If the ingredient list includes vague terms like "resin blend" or doesn't fully disclose ingredients, that's a sign to look for a more transparent option.

Use your current top & base coat more safely

If you're not ready to replace your current coats right away, small changes in how you apply them can reduce what you breathe in. Good ventilation is the simplest adjustment you can make.

Open a window or turn on a fan before you start painting, and keep the air flowing until your nails are fully dry.
Apply thin, even layers rather than thick coats — thinner layers dry faster and release fewer fumes into the air.

Choose cleaner replacements

Look for top and base coats that fully disclose every ingredient and skip the worst offenders: formaldehyde, toluene, DBP, phthalates, parabens, and synthetic fragrance. A shorter, transparent ingredient list is a better sign than a big "free-from" number on the label.

Avoid products that list methyl methacrylate (MMA), benzophenones, benzoyl peroxide, or dyes not approved for nail use like Red 3.
