I have only used them for two weeks so I can’t see any obvious results yet. However this serum is very lighweight, it is non-fragrance so it doesn’t irritate my sensitive skin at all! After applying my skin feels hydrating (but not sticky) so I don’t even need a moisturiser. I am a skincare minimalist so my current routine include cleanser, toner and this serum - that’s it! I would very likely repurchase, especially if I see good results after I end this bottle!
