Change Serum 15% Hydroxy Acid Complex AHA BHA LHA PHA

Change Serum 15% Hydroxy Acid Complex AHA BHA LHA PHA

8% AHA (Alpha Hydroxy Acids): Glycolic, Lactic & Mandelic Acid
4% PHA (Poly Hydroxy Acid): Gluconic Acid
2% BHA (Beta Hydroxy Acid): Salicylic Acid
1%  LHA (Lipo Hydroxy Acid): Capryolyl Salicylic Acid

An unique combination of mild acids acting at different levels in the skin, they "unglue" dead skin cells, prevent blemishes by antimicrobial action, even skin tone/reduce hyperpigmentation and reduce mild scarring by stimulating elastin and collagen synthesis. BHA and LHAs are fat soluble and work deeper in the skin/hair follicles. Read more about the science here.

The hydrating leave-on formula does not require moisturizing post application and can replace stronger, difficult to use peels.

It replaces SALIC, being twice as potent and with more uses. The first batch has black instead of white text on the label, we´ll get that sorted for the next one.

Very good
Awesome Results

I was one of the first to pre-order this serum. For background, I have had oily, acne prone skin since I was 14. I am now 55. I deal more with congested skin than with active pimples at this point. I had tried the Salic formula, but although effective on a superficial level, it left an oily residue that just didn’t feel good on my skin. To all my oily skinned friends, this Change serum works soooo much better for me! It is much stronger than the Salic formula, so if you have sensitive skin, be careful! I used to get Mini peels at a spa before Covid. This is the first serum that has even come close to giving me a nice, gentle peel if used a couple of nights a week. Brightens your skin, helps clear out blackheads and is more like a professional grade product. Again, for something you can purchase outside of an esthetician’s office, this is pretty strong. I find I can alternate nights with the Change Serum and the Night (retinol) serum. Doesn’t make me oilier and doesn’t make my skin dry, just the right balance. Quality formulations for acne or anti-aging benefits. Thanks to Johan who always answers my questions and gives good recommendations promptly.


Artboard 2Acne Bacteria growth vs pHP.Acnes growth in a cultured dishGrowth (24 hours)pH4.

Bacteria implicated with acne only grows when pH is over 4 (1983 Greenman) – hence, low pH products are ideal for acne-prone skin. Acne sufferers typically have higher (less acidic) skin pH, which is optimal for acne growth (2017 Prakash).

Aging regimen

1. Use Day every morning to moisturize and protect your skin from the sun (SPF not determined yet).

2. Use Night 2-5 times a week in the evening.
