Allow us to introduce you to your new skin care bestie, the mandelic acid serum. You want that fresh, clear, dewy skin without messing with and aggravating your skin? It is touted as one of the mildest alpha hydroxy acids (AHAs) and is adored by everyone with sensitive, acne-prone skin or aging skin.
Here is why this underestimated ingredient should also be a part of your skincare routine.

What is Mandelic Acid Serum?
Mandelic acid is an alpha hydroxy acid found in the bitter almond, whose molecule is considerably bigger than that of other alpha hydroxy acids such as glycolic or lactic acid. What about that then. It also will not irritate the skin as much since the penetration is slow.
In comparison to stronger acids, mandelic acid serum is gentle enough to produce optimal exfoliation, without irritation.
Benefits of Mandelic Acid Serum
Gentle Exfoliation for Sensitive Skin
We recommend its slow absorption formula for those with skin sensitive to high potent acids. It exfoliates without dryness for you.
Clears Acne and Blemishes
It has antibacterial qualities, which allows mandelic acid serum to decongest pores, lessen inflammation and control breakouts, particularly cystic or hormonal acne.
Improves Skin Texture
Send your bumpy and uneven skin off into retirement. Constant application results in a smooth skin and less prominent enlarged pores.
Reduces Hyperpigmentation and Dark Spots
Mandelic acid also quickens cell turnover to promote the fading of discoloration, including acne scarrings and sunspots.
Brightens Dull Skin
It gives energy to lackluster skin and restores luminous quality, and thus is an ideal choice when it comes to dull and uneven skin tone.
How Mandelic Acid Works on Skin
Slow Penetration for Minimal Irritation
Due to its bigger molecules, mandelic acid is absorbed more gradually into the skin, thus it will exfoliate without causing irritations.
Exfoliation Without Overdrying
As opposed to salicylic or glycolic, mandelic will not drain the life out of your skin. It is moisturizing to sustain the health of the skin barrier.
How to Use Mandelic Acid Serum Properly
Patch Testing Before Use
It is often advised to put a patch of new acid on first before rolling it out on the whole face–better to be safe than sorry.
Recommended Frequency and Application Tips
When first starting use 2-3 times a week at night. Gradually accumulate the amount of how your skin reacts. Alway apply moisturizer after.
What to Avoid When Using Mandelic Acid
Use this in a skincare routine that avoids combining it with retinol or vitamin C to avoid irritation. Go out with sunscreen.
Ideal Skin Types for Mandelic Acid
Oily and Acne-Prone Skin
It is oil-soluble thereby making it ideal in treating acne and blocked pores.
Sensitive and Rosacea-Prone Skin
Mandelic acid serum does not flare redness or district sensitivity as compared to other acids.
Mature and Aging Skin
It increases collagen levels, minimizes wrinkles and treats age spots- all without harsh exfoliation.
Common Myths About Mandelic Acid Serum
“It's too mild to be effective”
False! It’s not harsh but its steady and it packs a punch. Slow and steady is the way to skincare.
“AHAs are only for dry skin”
Nope. Mandelic acid is also a miracle to the greasy and mixed skin types.
Best Ingredients to Pair with Mandelic Acid
Niacinamide
All of them diminish inflammation, brighten pigmentation, and balance skin tones.
Hyaluronic Acid
Hydrates your skin after exfoliation. No dry or tight here
Peptides and Ceramides
Increase the skin barrier and enhance elasticity.

How Long Before You See Results?
