CeraVe replaces ceramides. Mac Pure replaces palmitoleic acid. Both are barrier lipids. They are not the same one.
CeraVe's ceramide science is real and well-supported. So is the palmitoleic acid mechanism behind Mac Pure. The reason both products exist is that aging skin loses more than one type of lipid. This page explains which one each product addresses.
Why CeraVe is the benchmark
CeraVe is the most dermatologist-recommended moisturiser in the world. Their three essential ceramides (1, 3, and 6-II), delivered via MVE (MultiVesicular Emulsion) technology, address a genuine and well-studied mechanism of skin aging: ceramide depletion.
Ceramides are intercellular lipids in the stratum corneum, the outermost layer of the skin. They form part of the structural mortar between skin cells. Ceramide levels decline with age. Replacing them supports barrier integrity and reduces water loss. This is real science and CeraVe executes it well.
If your dermatologist or GP recommended CeraVe, that is sound clinical advice.
What ceramides do not replace
The stratum corneum (ceramides) is one layer of the skin barrier. The sebum film produced by the sebaceous glands is a different layer.
Sebum contains palmitoleic acid, an omega-7 fatty acid. Palmitoleic acid is part of the skin's own barrier system at the surface level, above the stratum corneum. After age 40, sebum production declines steadily. CeraVe replaces ceramides. It does not contain palmitoleic acid. It does not address sebum fatty acid depletion. These are genuinely different mechanisms.
By age 70, sebaceous glands produce significantly less sebum than they did at 20. The decline is gradual, which is why many people find that products that worked well in their 40s become less effective with time.
Where Mac Pure fits
Mac Pure addresses the sebum layer, not the ceramide layer. Macadamia oil contains 17-22% palmitoleic acid, the highest concentration of any commercially viable plant oil used in skincare. The formulation is designed to supplement the fatty acid that aging sebaceous glands are no longer producing at adequate levels.
Mac Pure is not an alternative to CeraVe. It addresses a different part of the barrier. For some people with significantly depleted aging skin, the full picture involves both.
If you have been using CeraVe consistently and your skin still feels persistently dry or depleted in a way that does not fully resolve, the part that is not being addressed may be sebum fatty acid loss rather than ceramide loss.

What CeraVe does not address.
If your skin has changed with age and standard moisturisers are not fully resolving it, the missing layer may be sebum fatty acid, not ceramide. Mac Pure Calm+ is formulated to suit skin experiencing this type of depletion.
