If you’ve ever put on a pair of earrings and felt the familiar itch that signals a reaction coming, you’ve already understood something that By Invite Only built its entire brand around. Trixie Khong started making jewelry because she couldn’t wear most of what was available—her skin reacted to nickel, to cheap alloys, to the standard materials most jewelry is made from. The brand is essentially a solution to a problem she couldn’t find anywhere else. Whether the solution is worth what it costs is the question.
Why Sensitive Skin Changes the Jewelry Problem
Most jewelry is made from materials that work for most people. Sterling silver, gold, stainless steel—these are the mainstream options. But for the significant portion of the population whose skin reacts to specific materials, the mainstream options aren’t actually available.
Nickel is the most common allergen. It’s present in most alloys used for jewelry—not in pure gold or pure silver, but in the mixed metals that make jewelry affordable. Even jewelry labeled as “gold” often contains nickel alloys in the non-pure portions.
For people with sensitive skin or conditions like eczema, this isn’t a minor inconvenience. It’s a genuine barrier to wearing jewelry at all, or at least to wearing it comfortably. The reaction isn’t just cosmetic—it’s physical, uncomfortable, and sometimes takes days to subside after removing the offending piece.
By Invite Only’s proposition is direct: we make jewelry that people with sensitive skin can actually wear. This isn’t a niche concern—it affects a meaningful percentage of the population—but it’s a concern that mainstream jewelry brands largely ignore.
The Materials and What They Actually Mean
The brand uses several material tiers:
18K rose gold plated eco-brass with e-coating: Eco-brass is a nickel-free alloy that provides the base for the rose gold plating. The e-coating is a protective layer that further reduces the chance of skin reaction. Rose gold plating gives the visual finish without the pure gold price tag. This is the material used in most of the brand’s entry and mid-range pieces.
925 sterling silver: The standard for quality silver jewelry. By Invite Only’s use of actual sterling silver rather than silver-colored alloys is important for the sensitive skin customer—the purity means fewer potential allergens.
14K solid gold: The premium tier. Solid gold throughout means no alloys hidden in non-visible parts of the piece. For someone with severe nickel allergy, this is the only truly safe option at a reasonable price point.
The tarnish-free and waterproof claims deserve specific attention. These are functional benefits that matter practically. Tarnish-free means the piece looks good through regular wear without special care. Waterproof means you don’t have to remove it for swimming, showering, or activities where conventional jewelry would be damaged.
The Price Reality
By Invite Only’s pricing at S$40-1,200+ spans a wide range. Here’s the honest breakdown:
The entry range (S$40-90): Gold Paulette Studs at around S$49 represent the accessible entry point. You’re paying for the brand’s core proposition—hypoallergenic jewelry that doesn’t cause reactions—at the lowest price point the materials allow. If you’ve struggled to find jewelry you can wear, this is where to start.
The mid-range (S$90-200): The Cynthia cubic studs at around S$45 and comparable pieces represent the brand’s mainstream offering. The pricing reflects the material quality and the e-coating process that makes the pieces safe for sensitive skin. Most everyday pieces—earrings, small necklaces, bracelets—sit in this range.
The premium (S$200-490): The 10K Gold Evangeline Necklace at S$490 is where the brand moves into fine jewelry territory. The price reflects the solid gold content and the design ambition. This is for customers who want something more substantial and are willing to invest.
The fine jewelry tier (S$390-1,200+): The Gldsmth collection with 14K recycled gold and white sapphires at S$390 and the White Gold Diamond Bar Necklace at S$1,200 represent the brand’s highest expression. These pieces are for customers who want genuine fine jewelry with the additional guarantee of being safe for sensitive skin.
What Makes By Invite Only Different from Other Sensitive Skin Jewelry
The market for sensitive skin jewelry exists, but most options fall into one of two categories: medical-grade titanium pieces that look clinical, or expensive solid gold pieces from traditional fine jewelers.
By Invite Only occupies a different space. The design language is contemporary and fashionable, not clinical. The materials are chosen for both skin safety and aesthetic quality. The rose gold plated eco-brass looks like fashion jewelry, not like a medical device.
The waterproof and tarnish-free features are also differentiating. Most jewelry brands that claim hypoallergenic still require you to remove pieces for swimming or showering. By Invite Only’s e-coated pieces can be worn continuously, which is more convenient and means the jewelry integrates into daily life rather than being a special-occasion item.
The Singapore Context
Singapore’s climate creates specific challenges for jewelry. Humidity and perspiration accelerate tarnishing in conventional jewelry. The aggressive air conditioning in most indoor spaces creates a temperature contrast that affects some materials. Salt air in coastal areas adds another variable.
By Invite Only’s tarnish-free and waterproof properties address these climate challenges directly. A piece that can handle Singapore’s humidity without special care is more practical than a piece that requires regular cleaning and storage in airtight containers.
The free shipping above S$50 is also worth noting. Most Singapore jewelry brands offer this or similar thresholds, but By Invite Only’s threshold is modest enough that a pair of earrings or a small necklace qualifies without requiring additional purchases.
What to Actually Buy from By Invite Only
Stud earrings if you’re trying the brand for the first time: The gold Paulette studs or Cynthia cubic studs at S$45-49 are the right entry point. Earrings make contact with some of the most sensitive skin on the body, and if you’ve had reactions to earrings before, this is where to test whether the brand works for you.
Huggie earrings for everyday wear: The huggie style (small hoops that hug the earlobe) is versatile and comfortable. At S$45-59 for the mid-range options, these are practical for daily wear without the worry of reactions.
A necklace for layering: The everyday necklaces at S$69 and similar price points are designed for layering—a look that’s been popular and allows for mixing and matching. The sensitive skin guarantee means you can layer without the cumulative reaction risk.
The fine jewelry collection if you’re investing: The Gldsmth pieces with recycled gold and diamonds at S$390-1,200 are genuine fine jewelry purchases. If you want something that will last and that you can wear without worrying about skin reactions, this is where to invest.
The Honest Assessment
By Invite Only solves a real problem that mainstream jewelry brands ignore. The founder’s personal experience with sensitive skin is embedded in how the brand thinks about materials and design—not as a marketing story, but as a genuine product requirement.
The pricing is accessible for what you’re getting. The entry-level pieces at S$40-90 are not cheap for fashion jewelry, but they’re not expensive for jewelry that’s genuinely safe for sensitive skin. The premium fine jewelry tier at S$400-1,200+ competes with traditional fine jewelers while offering the additional skin safety guarantee.
The waterproof and tarnish-free features are practical benefits that justify themselves in the Singapore context. A piece you can wear in the shower, at the pool, and through humid days without worrying about it is more integrated into daily life than a piece that requires careful handling.
The recommendation: if you’ve ever had a reaction to jewelry, By Invite Only is worth trying. Start with a pair of stud earrings in the S$45-90 range, see how your skin responds, and build from there if the brand works for you.
