MEDITHERAPY Retinal Skin Booster Serum | Retinaldehyde, Niacinamide Anti-Aging Serum - K-Beauty Facial Serum for Fine Lines, Firming & Radiance | Hydrating Face Serum All Skin Types, 5.07 fl oz

yes, absolutely! if you have never used before, i would start with the meditherapy retinal skin booster, because it is so gentle and lasts up to six months if kept refrigerated. it is a rather large bottle tho so if you don’t think you’ll be able to use it all within six months, then i would go for the ksecret 1% retinal cream, and work your way up to the stronger %’s after each bottle empties 💕
