The purging stage, but this retinol serum are hydrating, the formulation is good

2.5% considered high percentage for beginner, but this is my first retinol,  the purging I experience is not bad as I really moisturizer my skin . My skin glow after 3-4 week of usage,  I use it once per week, then twice per week,  3x per week, and daily use.

I&#39;ve read a lot of good review about azelaic acid,  so decide to try this one cuz I&#39;ve been using few product from CDB,  it&#39;s doesn&#39;t irritate my skin,  I use it 2 times a day, as I can&#39;t use retinol due to pregnancy,  this is a safe and great alternative to tackle the incoming acne&#47;melasma&#47;pigmentation .

This is a good Bha but I can&#39;t handle the purging, it worse than using retinol.  I&#39;ve use this 3 day straight when I experience sudden hormonal acne&#47;or due to traveling,  this toner helps rid those crazy acne

Texture is light ,watery texture kinda make people thinks it didn&#39;t work out

Really good on calming redness, pimple,  I got acne in first trimester this ampoule is a life savior.  It&#39;s lightweight so I use this as my first treatment.

None,  it&#39;s a good product, 240ml can use for months plus it cheap

It&#39;s helps fighting whiteheads, which really bother me before. I use it once per week,  didn&#39;t irritate my skin, just a bit tingle sensation.
