TanReady calculates your self-tan development time based on today's humidity and temperature — so you never go orange or streaky again.
Live Example
Development times are estimates. Results vary by individual skin chemistry, product brand, and application technique.
Why It Matters
Sweat activates during development. In humid conditions, DHA reacts unevenly with skin oils, creating patches and streaks no matter how carefully you applied.
DHA undergoes a Maillard reaction with amino acids in your skin. Heat accelerates this — significantly shortening the time before you go too dark.
Dry air evaporates the product too fast on skin surface before DHA can fully develop. Result: uneven, patchy color — especially on elbows and knees.
DHA barely reacts in cold temperatures. You leave it on for hours, shower, and see almost no color. Your $35 bottle did nothing.
