#1
Best Overall Alternative
The why
A lipid-rich barrier moisturizer with ceramide NG, urea, glycerin, and peptides, built for dry or retinoid-stressed skin. It layers well under makeup and sinks in, but oily or breakout-prone users may find the richness triggering.
One minus

Good forDry Skin, Sensitive Skin
Both recommended for Skin Barrier.

- Size: 100 ml
The why
A panthenol-and-centella repair balm with dimethicone that seals in hydration after over-exfoliation, wind, or eczema flares. Dry, reactive skin gets the most mileage; oily, clog-prone users may find the heavy film triggers congestion or irritation.
One minus
Thick, greasy texture can sit on skin and look shiny
Good forDry Skin, Sensitive Skin
Both recommended for Skin Barrier.
“I only use it on my cheeks and only occasionally, so not as a regular moisturiser.”
