Your skin didn't change overnight. It started running warm.
Flushing that lingers. Moisture that leaves faster than it used to. A face that reads tired by three in the afternoon. Kestia is built for skin in this exact moment.
Two products. One routine.
Start with the set — it's the routine the four-week study used, and it costs less than buying both. Or take one step at a time.
The Balance Set
The pads sweep and settle. The cream seals it in. Together they are the exact routine used in our four-week study — b...
Balance Nutrition Cream
Light enough for a warm room, cushioned enough for a cold one. It absorbs without the film that makes warm skin feel ...
Balance Serum Pads
Soaked, not damp. One sweep over warm skin lifts the day off and leaves a cool, even finish behind — the step that do...
Reserve
It starts as rambutan peel — the red, hairy shell of a tropical fruit that the food industry throws away at a rate of roughly a million tons a year. We buy it, and we pull the good part out.
Most botanical extraction runs on methanol or ethanol. Ours uses a natural deep eutectic solvent — a solvent built from things you could eat. The method was published in Food Chemistry in 2025.
The compounds are geraniin, corilagin and gallic acid, tested against four stressors: infrared heat, ultraviolet light, a surfactant, and retinol.
Three to know, alongside it.
Rambutan Reserve is the signature of the formula. These three are the best-studied ingredients working alongside it.
Helps reduce the look of redness and blotchiness, and helps skin hold on to moisture.
Larger molecules hold water at the surface; smaller ones reach the upper layers of skin. Plumps the look of fine lines.
Feels cool on contact and soothes skin that feels warm.
These notes describe why each ingredient is in the routine. Only the figures under Clinical results come from testing Kestia itself. Kestia is a cosmetic, intended to affect the appearance and feel of skin only.
What changed, and by how much.
Two separate studies, kept separate. Every number below is a change in the direction we wanted.
After four weeks of Balance Nutrition Cream
Finished product · 20 women aged 30–60
After one application, on heat-stressed skin
Essence containing the complex, against untreated skin
Four-week figures: Balance Nutrition Cream, finished-product human application study, 20 female participants aged 30–60, each measured against her own baseline. Single-application figures: 21 female participants, ages 26–53, using an essence containing the Rambutan Reserve complex, measured against untreated skin on the same person. Both studies conducted in the Republic of Korea. Figures are averages; individual results vary.
Heat-Reactive Skin
Skin that flushes more easily, holds water less well, and takes longer to look calm again after it warms — from a hot room, a hot drink, exercise, or a wave of internal heat.
It is not a medical condition and it is not a diagnosis. It is a way of naming what many women start seeing in their forties, and what Kestia is formulated to address.
What Kestia is not.
It contains no estrogen and no added hormones of any kind.
It is not a hormone replacement and is not a substitute for one.
It works on the surface of the skin. It cannot act anywhere else in the body.
Make something about this.
Skincare for women over thirty-five is one of the least crowded corners of TikTok Shop. We send the full routine free, pay 15–25% commission, and don't write scripts.
