Love it! - 29-04-2018 by

I have used this serum for years and it remains one of my favourite products. It is great for sensitive users and keeps my skin hydrated in combination with a moisturiser as well. I alternate this every second night and use the Alpha H liquid gold on the other. My skin is clear and radiant. Very happy with the results.

The perfect retinol serum for sensitised or reactive skin - 03-04-2018 by

I love this product and have used several bottles of it, but I have also recommended it to plenty of people as well. It is a mild retinol which allows the user to enjoy the benefits of Vitamin A derivatives (eg rebuilding, strengthening, anti-ageing, antioxidant, repairing sun damage) without risking the inflammation of a full-on retinol serum or prescribed retinoid.
Serum 16 is perfect for the following types of skin:
- Sensitive rosacea-type skins
- Thin, fragile, aged skin
- Anyone who needs a retinoid more for rebuilding rather than retexturising.

My only problem with this is it does have a lavender/herbal type scent which I guess could be irritating in some skins, but in my experience most people with even really reactive/sensitised skin can use this! Just start every second or third night and work up to nightly use after a few weeks. Follow with moisturiser and wear sunscreen during the day.

Love this serum - works on my large pores and blemishes - 09-01-2018 by

This was recommend by my facialist instead of the discontinued aspects one I was using.
Works amazing one pump goes a long way.
I was told to wet my fingers and work it onto my skin by patting gently and my skin always looks amazing the next day.
Works on blemishes I put a small amount on them and but morning they are starting to disappear.
