active = base × active%; liquid = base × liquid%= 2
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 does the calculator determine ingredient proportions for a DIY face mask?+
It scales a base recipe's ratio of ingredients (such as a clay, a liquid binder, and an active additive) up or down to your desired total batch size, keeping each ingredient's proportion of the whole constant so the mask's texture and effect are consistent regardless of batch size.
Why does the ratio of clay to liquid matter so much for texture?+
Too much liquid relative to clay produces a runny mask that is hard to apply and drips before it can work, while too little liquid makes a stiff, hard-to-spread paste that can dry out and crack too quickly on the skin, so the ratio directly determines whether the mask is usable.
Can I substitute one liquid ingredient for another while keeping the same ratio?+
Generally yes for similar-consistency liquids (like swapping water for a hydrosol), but substituting a thicker liquid (like honey) for a thin one (like water) at the same ratio will change the final texture even though the proportions on paper are identical, so some adjustment may still be needed.
Why should active ingredients like acids or essential oils not simply follow the same scaling ratio as the base?+
Active ingredients often have a maximum safe usage percentage independent of the base recipe's proportions, so when scaling a mask up, actives should be capped at their known safe percentage of the total rather than scaled purely in line with the base clay-to-liquid ratio, to avoid irritation.
How long can a mixed batch of a DIY mask be stored before the ratio or safety changes?+
Fresh, water-containing DIY masks without a proper preservative typically should be used within a day or so, since without adequate preservation microbial growth can occur even if the physical ingredient ratio remains visually unchanged, so the calculated ratio does not address shelf life or safety over time.
