If you’re looking for the single most effective anti-aging treatment serum, you’ve found it with Saranghae Advanced Renewal Retinal Serum with 0.1% Retinal + 2% Squalane.  Retinal (short for retinaldehyde) is a retinoid form of vitamin A.  It is further along the Vitamin A pathway than retinol, and just one conversion step away from becoming retinoic acid.  Retinal is 20X more powerful than retinol and acts faster on our skin with little to no irritation synonymous with retinol.  Even sensitive skin types that couldn’t handle retinol in the past will be candidates to enjoy the anti-aging benefits of 0.1% retinal with no skin irritation.
