Note
This is a simplified model: it applies the mixing ratio, dilution, application rate, growth rate or price you enter to plain arithmetic. Mixing figures use the ratio on your own product's label, because developer, powder and colour ratios differ from brand to brand. Dilutions use C1 x V1 = C2 x V2 and the standard conversion of 20 drops per millilitre; real droppers vary with the oil's viscosity and the dropper itself. Sunscreen amounts use the Du Bois body surface area formula with the application rate you enter, and the SPF figure uses the textbook approximation protection time = SPF x unprotected burn time, which is a simplification: sweat, water, towelling, UV index, altitude, reflection and your own skin all shorten it in practice. Hair, nail and hair-removal timings assume a constant linear growth rate, which varies by person, body area, age, season and health. Costs ignore taxes, sales and waste. Always patch test a new product on a small area first and follow the product label and any professional instructions. This is not dermatological, cosmetic or medical advice; see a dermatologist or a qualified professional for anything affecting your skin, scalp or health.

How much moisturiser is actually recommended per application?+
A commonly cited guideline for the face is about a nickel- or pea-sized amount (roughly 1-2 grams or about a quarter to half a teaspoon), though this varies with product richness and the size of the area being covered; the calculator applies standard per-area benchmarks to estimate a reasonable amount.
Why does covering a larger area not need proportionally much more product?+
Thin, even layers spread further than expected because the goal is a light film rather than a thick coating, so while more surface area does require more product, the relationship is not perfectly linear once you account for how differently textured formulas (gel versus cream) spread.
Does using more moisturiser than recommended improve hydration?+
Beyond a certain point, excess product mostly sits on the skin's surface without being absorbed, since skin can only take up so much moisture and active ingredients at a time; using more than the recommended amount tends to waste product rather than meaningfully improve results.
Why would the same product amount feel different on different skin types?+
Dry skin often needs a slightly larger amount or a richer formula to feel adequately moisturised, while oily skin may need less of the same product to avoid feeling greasy, so the 'right' amount is a starting estimate that should be adjusted based on how your skin responds.
How does climate or season affect how much moisturiser I should use?+
Colder, drier air increases water loss from the skin, which often calls for a slightly larger amount or a richer formulation in winter, while humid conditions may call for less product to avoid an overly heavy or greasy feel.
