Body Moisturizer Application Amount
Covering the whole body in one go, an average adult goes through somewhere between 15 mL and 30 mL of moisturizer, which dermatologists put at about 1 to 2 tablespoons. If you want a quick number to work with, mL = peso_kg × 0.3 does the job. That puts a 70 kg adult at roughly 21 mL each time.
Put it on damp skin within 3 minutes of stepping out of the shower so the water gets sealed into the stratum corneum. That is the "soak and seal" approach the American Academy of Dermatology recommends. The actives that actually do something here are urea (5–10% for normal-dry skin, 10–30% when it is rough or keratotic), glycerin, ceramides, hyaluronic acid, plus sweet almond oil.
Applications
Work out what you spend on product each month, figure out how big a pump bottle a couple or a family really needs, plan how much to decant for a trip. It also helps when you are weighing up brands such as CeraVe Moisturizing Cream, La Roche-Posay Lipikar or Eucerin Advanced Repair, or tweaking the amount for xerosis, atopic dermatitis or ichthyosis with a dermatologist guiding you.
FAQ
How much moisturizer for the whole body? For an average adult, count on 15–30 mL each time, so 1 to 2 tablespoons. The taller or heavier you are, the more you will get through.
When should I apply it? Try to do it within 3 minutes of bathing while your skin is still a bit damp, since that holds in the most moisture.
Is the calculator a medical prescription? No. Treat it as a ballpark figure drawn from ANVISA category 1 cosmetic guidance. If you have a specific skin condition, get a dermatologist to look at it.
