Glycolic, salicylic, lactic, gluconolactone... Which acid is right for you?
If you think that using acid is only for experts, think again! Used correctly, some acids can actually work wonders on sensitive skins. Which ones to use? How? When? Our guide is required reading if you want to benefit from the ‘wow’ effects of using the right acid on your skin.
Glycolic acid, the great multi-spot champion
L'glycolic acid is a member of the fruit acid family. Thanks to its low molecular weight, which is able to penetrate deep into the skin, it is considered a fairly powerful exfoliating agent, used in professional peels in particular. Rely on it to target the following issues: blurred complexion, pigment spots, pimples and traces of old pimples, wrinkles.

Lactic acid, the gentlest exfoliant
Naturally produced by the skin, this postbiotic (made by the good bacteria in your epidermis) eliminates bad bacteria by lowering skin pH. The result is calmed rednessand a reinforced skin shield and a clearer complexion. Depending on its concentration, some of lactic acid's actions will vary: at 2% it can moisturize and plump, and at 5% and above it can act as a gentle exfoliant. Perfect for correct skin texture !

Salicylic acid, the enemy of spots and scars
It's its purifying properties that make salicylic acid a favorite for blemished skin. Powerful for unclog pores and prevent blackheadsSalicylic acid is ideal for daily use 2 to 3 times a week (or even more if the skin is thick and the concentration low), for skin that tends to mark easily.

Retinoic acid or retinol, the anti-ageing must-have
Derived from vitamin A, retinol does the opposite of most acids: instead of refining the skin, it thickens its top layer to better fill in wrinkles. An anti-aging active par excellence, retinoic acid knocks out the enzymes responsible for skin aging and regulates melanocytes (the mini-machines that produce melanin), to better prevent brown spots.

Your questions
Can you combine products containing different acids or is that dangerous?
As a general rule, we advise you to avoid... But it all depends on which acid(s) we're talking about, as well as the level of concentration in the formula and other active ingredients that can "temper" the action of the acid in question. Typical example: you realize that your cleanser contains salicylic acid and then you use a retinol-based serum. Chances are, the concentration of salicylic acid in that cleanser is very low. And if you haven't noticed any redness, heating or dehydration, then everything is fine. But if in doubt, ask us ;-)
How often can I use acid-based products?
We cannot give you a precise answer because too many parameters come into play: the integral composition of the product, which may combine other exfoliating/stimulating active ingredients, your sensitivity and the other skin care products you use on a daily basis. If you are not sure, contact us.
Hyaluronic acid ?
If we haven't mentioned it in this article, it's simply because hyaluronic acid is an active ingredient that has no "peeling" effect, unlike those mentioned. But it is an excellent anti-ageing and universal moisturizing molecule that we also warmly recommend!
What about ascorbic acid?
This acid is vitamin C. Super protective of our skinAscorbic acid is not an exfoliant, but acts as a real vacuum cleaner for toxic substances (such as pollution particles, cigarettes...), while stimulating our production of collagen fibers. So you can maintain a luminous complexion and youthful skin for longer. Use it from the age of 25/30 for a combination of radiance and anti-aging prevention.
