Two things worth mentioning from the get-go. 1. It's rare that I radically change my initial opinion of a product 2. I don't usually see that much (positive) difference when using different skincare - I may see slight changes and my skin may feel better but it's rare for it to be really noticable. When testing
The Ordinary's Lactic Acid 10% not only did my initial opinion do a complete U-turn but my god I could see the difference.
For my first order from The Ordinary I choose three things;
hyaluronic acid which is the basis for a lot of serums that cost about ten times more than this one,
Ascorbyl Tetraisopalmitate Solution 20% in Vitamin F as an alternative to my beloved Ole Henriksen Truth Serum, and
Lactic Acid 10% (the HA 2% stands for Hyularonic Acid) as an AHA since I don't use Retinol while pregnant and my face was looking pretty horrendous. More on the other two to come but it was the lactic acid that was a real eye opener.
Now, having done this for over a decade you'd think I'd have learned my lesson by now but I obviously haven't. So excited was I that I tried them all at the same time, at different times of day, and at the same time used a new SPF and my spots went from quite bad to absolutely horrendous. I thought it was the SPF but also suspected the lactic acid which I had just started slapping on my face at the end of the day. I had no choice but to stop using everything new, give my skin two weeks off and then start again one new product at a time. Like I should have done in the first place.
