?? Andrew Anthony Toledo Location : Skin types : Age : Location : Date Holy Grail for Spots and Acne Marks
5/5 This is just an effective serum for your blemished skin. I thought there is no cure for my complexion. Good thing, I always research the web for good reviews. This one has had the most best reviews. It's been just 2 weeks and I could see drastic change on my skin. I am not planning on trying C21.5. You could use my promo code for additional $5 on your 1st purchase. Promo code: 3013778210

4.5/5 Este serum es muy bueno mejorando la textura de la piel, me ayudó a sanar brotes de acné y a desaparecer manchas y cicatrices de acné, es un producto muy bueno, lo único que no me gusta es que tras aplicarlo la piel queda un poco pegajosa
?? Asyih Fitriyani Location : Skin types : Age : Location : Date Best Serum for cure acne

?? Celine Khauv Location : Skin types : Age : Location : Date Great product
4.5/5 I've been using this until the new one came out and I totally love both of them! This one is stickier but it still does the job well (why i give it a 4.5). It helped heal my acne scars faster and it brightened my skin tone!
