The word "acid" makes me think of
frightening chemical burns and bubbling test tubes. Yet, acids are among the
most advantageous chemicals for skin care when applied in the proper amounts.
These are the wonder weapons against scars,
uneven skin tone, wrinkles, age spots, and acne. However, it might be confusing
to know which acids to use, for what purposes, and which items to purchase with
the wide variety of acids available on the market. Before anything else, you
need to know where to begin.
The most well-known acid
Salicylic acid has been in existence for a
while. Its well-known properties of keeping pores clear and exfoliating the
skin aid in lessening acne. It can be found in cleansers and serums in
concentrations ranging from 0.5 to 2 percent and in spot treatments for acne.
In dermatological clinics, salicylic acid is
also used in higher concentrations as a peeling agent to treat sun damage, age
spots, melasma, and acne. It is safe to use on dark skin prone to pigmentation,
yet it is so effective that it is utilized in treatments to eradicate corns and
warts. Being related to acetylsalicylic acid, the active ingredient in aspirin,
it likewise possesses anti-inflammatory qualities.
An ant-aging weapon
The most common alpha-hydroxy acid (AHA)
utilized in skin care products is glycolic acid. Being the smallest AHA and
derived from sugar cane, it has the highest skin penetration rate. An amazing
anti-aging substance that appears to work on everything is glycolic acid.
It works wonders for avoiding acne, eliminating
dark spots, thickening the skin, minimizing fine wrinkles, and balancing out
the tone and texture of the skin. It follows that its presence in a lot of cult
skin care products is not surprising. Usually, concentrations less than 10% are
detected.
The smoothening exfoliant
Another alpha-hydroxy acid that comes from
bitter almonds is called mandelic acid. It's an exfoliating ingredient that
works similarly to glycolic acid to cure sun damage, prevent acne, and balance
skin pigmentation.
On the other hand, because of its bigger
molecular structure, it is less irritating to the skin because it does not
penetrate as deeply as glycolic acid. Because of this, it is frequently advised
to peel in place of glycolic acid, especially for ethnic skin types that are
more likely to see rebound pigmentation. Rebound pigmentation is the result of
overuse of a chemical, which causes a resistance to develop. This results in
the drug being not only ineffective but frequently having the opposite effect
from what was intended.
Say goodbye to pimple
For the past thirty years, azelaic acid has been
a cornerstone in the treatment of mild acne and may be found in numerous
lotions that are prescribed solely. It eliminates bacteria, lessens
inflammation and maintains pores clear. It is typically found in creams
intended for all-over application, morning and night, with concentrations of 15
to 20 percent. Although azelaic acid usually has relatively minimal side
effects, it might cause stinging, peeling, and redness in certain individuals
with extremely sensitive skin.
Azelaic acid is a skin-lightening substance that
can be used to cure acne as well as post-inflammatory hyperpigmentation or fade
blemishes left by acne. It is often used in conjunction with retinoids as a
less harsh substitute for hydroquinone.
The brightening,
whitening agent
Bacteria that are employed in the fermentation
of rice to make sake create kojic acid. Because of its whitening and anti-aging
qualities, it's a common ingredient in Asian skincare products. Trusted Source.
(Many Asian skincare brands refer to the process of reducing uneven skin tone
and hyperpigmentation as "whitening.").
Concentrations from 1 to 4 percent can be found
in cleansers and serums. Though regrettably quite irritating to the skin, it
works well.
Vitamin C’s sister
The most popular water-soluble form of vitamin
C, ascorbic, has anti-aging properties and is utilized in skin care products.
When treating melasma, it has also been utilized as a hydroquinone substitute Trusted
Source. Ascorbic acid is often found in more stable forms under the names
magnesium ascorbyl phosphate and tetra-iso palmitoyl ascorbic acid since it is
highly unstable in the presence of oxygen and water.
Which Acid should you use?
The challenging element is deciding which acid
to employ. Knowing what issue you wish to address is the simplest way to
approach it.

Don’t mix face acids
Salicylic acid should never be used with another
acid at the same time. When combined, severe skin irritation could happen.
Steer clear of salicylic acid when using
niacinamide-containing treatments.
Avoid combining lactic or glycolic acids with
ascorbic acid (vitamin C). This will make the benefits of the ascorbic acid
vanish even before they start to manifest.
AHAs should not be used with retinol.
