MAC Golden Elixir is a moderately warm-toned, medium-dark brown with a luminous finish. It is a limited edition highlighter that retails for $31.00 and contains 1.7 oz.
MAC Golden Elixir Strobe Liquid ($31.00 for 1.7 fl. oz.) is described as a "golden shimmer." It's a warm-toned, bronze and gold-shimmered tan brown. I don't know of any specific dupes, as I'm not as familiar with the liquid illuminator category, so I haven't reviewed many products previously. NARS Maldives is somewhat similar, but it is more pigmented and in stick-form, but NARS does have a liquid illuminator range, so my guess would be that this would be somewhat similar to Laguna. The thing with illuminators like this, though, is that they are very subtle once applied so while Tom Ford Fire Lust doesn't look similar when swatched, when applied, they seemed to both offer the same effect.
Blending soft-focus diffusers with iridescent pigments, this ultra-fluid strobe formula produces a soft, radiant light on the skin, reducing the appearance of skin imperfections by providing a natural-looking glow. Refreshing. Spreads on smoothly and absorbs quickly. Leaves the skin looking healthier and more radiant. A lighter-weight addition to the popular Strobe Cream.
