Aloe 2% + NAG 2% Solution

Looks good 4.2 / 5

A credible, fragrance-free post-acne serum with a sensible soothing/hydrating formula and verified INCI, but it is best viewed as a supportive maintenance product rather than a strong corrective treatment.

Skin

How it’s judged

Scored for skin — based on what its ingredients contribute.

What it may help with

Hydration i3.5 / 4

Whether the ingredient helps increase the skin’s water content — humectants that attract water, ingredients that reduce water loss, or ones that make skin feel less dry.

From Glycerin, Biosaccharide Gum-2, Acetyl Glucosamine, Pentylene Glycol

Texture i3.0 / 4

Whether it can improve smoothness and surface texture — roughness, flaking, clogged pores, or unevenness. Exfoliating acids, retinoids, and smoothing moisturizers may score here.

From Lactic Acid, Palmitoyl Pentapeptide-4, Glycerin, Acetyl Glucosamine

Anti aging i2.8 / 4

Whether it can help visible signs of aging — fine lines, wrinkles, loss of firmness, or photoaging.

From Palmitoyl Pentapeptide-4, Lactic Acid, Glycerin

Soothing i2.8 / 4

Whether it can calm the skin — linked to less redness, irritation, discomfort, or visible reactivity.

From Hydroxymethoxyphenyl Decanone, Aloe Barbadensis Leaf Juice Powder, Biosaccharide Gum-2, Glycerin

Pigmentation i2.8 / 4

Whether it can help uneven tone, dark spots, melasma-like discoloration, or post-inflammatory hyperpigmentation — including brightening and tyrosinase-inhibiting ingredients.

From Acetyl Glucosamine, Lactic Acid

Things to watch

Photosensitivity i3.0 / 4

Whether it can make skin more sensitive to sunlight, raising the risk of sunburn or UV-related irritation. Relevant for some exfoliating acids, retinoids, and certain plant-derived ingredients.

From Lactic Acid

Irritation i2.0 / 4

Risk of short-term irritation — stinging, burning, dryness, redness, or discomfort. Common for strong actives, acids, retinoids, fragrances, and harsh surfactants.

From Lactic Acid, Ethylhexylglycerin, Phenoxyethanol, Pentylene Glycol

Sensitization i1.5 / 4

Risk of allergic contact dermatitis or immune-based reactions. Fragrance allergens, preservatives, botanicals, and some dyes may score here.

From Chlorphenesin, Lactic Acid, Ethylhexylglycerin, Phenoxyethanol

Eye irritation i1.5 / 4

Whether it may sting or irritate around the eyes. Relevant for sunscreens, fragrances, acids, surfactants, and volatile ingredients.

From Phenoxyethanol, Lactic Acid, Ethylhexylglycerin

Barrier disruption i1.5 / 4

Whether it can weaken or damage the skin barrier — harsh surfactants, strong exfoliants, high alcohol content, or overuse-prone actives.

From Lactic Acid

About this product

A water-based leave-on serum from The Ordinary positioned for post-acne marks and blemish-prone skin. The verified formula is a short, fragrance-free blend centered on humectants, aloe, N-acetyl glucosamine, and a peptide, which suggests a soothing and lightly hydrating profile. Evidence from the brand and named retailers supports the product identity and ingredient list, but performance for dark marks is likely moderate rather than fast-acting.

Good signs
  • Fragrance-free and relatively simple, which lowers the risk of avoidable irritation.
  • Humectants and aloe support lightweight hydration and a soothing feel.
  • Includes N-acetyl glucosamine and a peptide, which gives the formula a rational approach to post-blemish care.
Watch-outs
  • Lactic acid is present, so very sensitive or barrier-impaired skin may experience mild stinging.
  • The formula is light and may not provide enough moisture for dry skin without a moisturizer.
  • Marketing for post-acne marks may outpace the visible results for deeper pigmentation or scarring.
Best for
  • blemish-prone skin
  • post-acne marks
  • lightweight daily serum use
  • users avoiding fragrance
  • normal
  • oily
  • combination
  • acne-prone
  • sensitive
How to use it
  • Apply a few drops to clean skin morning and evening.
  • Layer before moisturizer and sunscreen.
  • Patch test if skin is easily irritated by acids or glycols.
