What do the experts say about Facial Treatment Essence?
SK-II Facial Treatment Essence carries a Guru Score of 80% from 16 independent experts. This essence earns near-universal praise for visibly brightening skin and locking in hydration, making it an effective prep step that helps subsequent products absorb better. The star ingredient is a concentrated yeast ferment (galactomyces) rich in amino acids and vitamins that support skin renewal, particularly valued by those who cannot tolerate vitamin C or actives. The genuine split is on value: most gurus acknowledge the £80, £190 price is steep and that cheaper fermented yeast alternatives exist and work well, yet several note the SK-II formulation is more concentrated and delivers faster, more visible results, so the longevity of each bottle may justify the outlay for those with dry or sensitive skin. Apply by tapping or patting rather than splashing to get the full hydrating benefit.
What do the experts say about Advanced Snail 96 Mucin Power Essence?
COSRX Advanced Snail 96 Mucin Power Essence carries a Guru Score of 78% from 28 independent experts. The high concentration of snail mucin delivers noticeable hydration and a plump, glassy-looking finish that most gurus praise, especially for sensitive or compromised skin after procedures. However, snail mucin carries a higher allergic risk than many ingredients, so patch testing matters, and anyone allergic to shellfish or mollusks should avoid it altogether. Some find the texture sticky or feel they need to reapply often, though many love how it calms irritation and doesn't overload oily skin.
