A "complex" usually means a blend rather than a single active. Here, the 0.3% figure combines pure retinol with retinyl propionate, a retinyl ester. Esters are milder and must convert before they work, so a blend labeled 0.3% may deliver less real retinol than the number suggests.
Because the split between retinol and the ester is not disclosed, you cannot tell how much true retinol you are getting — only that it is less than 0.3%.
The rest of the formula is genuinely soothing, with peptides and a gentle base built for reactive skin. Just read the "complex" as a blend, not a pure dose.

The supporting formula is genuinely soothing, which is First Aid Beauty's real strength — colloidal oatmeal, peptides, and a gentle base built for reactive skin.
Fragrance-free, which matters in a retinoid.
If your skin is very sensitive and you want the mildest possible introduction, the gentleness is real.
Irritation is expected, not a sign it is "working." Redness, flaking and stinging in the first weeks are common with any real retinoid. Start twice a week and build up. If it is still angry after a few weeks, the dose is too high for you.
The "0.3% retinol complex" is a blend, and part of that blend is retinyl propionate — a retinyl ester.
Esters sit at the bottom of the retinoid ladder. They must convert to retinol, then to retinal, then to retinoic acid. The pure-retinol fraction is not disclosed, so you do not know how much real retinol you are getting — only that it is less than 0.3%.
The product this replaced was more honest. FAB used to sell a "0.25% Pure Concentrate" — genuinely 0.25% retinol, plainly stated. It appears to have been phased out in favor of a "0.3% complex" that sounds stronger and may well deliver less. That is a step backwards for the consumer.

1. Retinyl propionate and climbazole combination demonstrates clinical improvement to the appearance of hyperpigmentation and deep wrinkling with minimal irritation (https://pubmed.ncbi.nlm.nih.gov/28733999/) — Backs that retinyl propionate is a genuine retinyl-ester retinoid that delivers anti-aging benefit comparable to 0.1% retinol while causing significantly less irritation, supporting the page's 'gentle retinoid' framing. 2. A clinicopathological study of the effects of topical retinyl propionate cream in skin photoageing (https://pubmed.ncbi.nlm.nih.gov/9894360/) — Confirms retinyl propionate is a topically studied retinyl ester used on skin, supporting the page's statement that part of the '0.3% retinol complex' blend is the retinyl ester retinyl propionate. 3. Enhanced retinoid response by a combination of the vitamin A ester retinyl propionate with niacinamide and a flavonoid containing Ceratonia siliqua extract in retinoid responsive in vitro models (https://pubmed.ncbi.nlm.nih.gov/33048363/) — Backs the mechanism that retinyl propionate is a vitamin A ester metabolized toward trans-retinoic acid and activates the retinoid (RARalpha) pathway, i.e. it counts as a real retinoid. 4. Colloidal Oatmeal Part I: History, Basic Science, Mechanism of Action, and Clinical Efficacy in the Treatment of Atopic Dermatitis (https://pubmed.ncbi.nlm.nih.gov/33026768/) — Supports the claim that colloidal oatmeal is genuinely soothing, with anti-inflammatory, anti-pruritic, barrier-repair and skin-pH benefits well suited to reactive/sensitive skin. 5. Dihydroavenanthramide D Enhances Skin Barrier Function through Upregulation of Epidermal Tight Junction Expression (https://www.mdpi.com/1467-3045/46/9/547) — Confirms avenanthramides, the primary bioactive components of colloidal oatmeal, strengthen the skin barrier and alleviate irritation, supporting the 'soothing base built for reactive skin' claim. 6. Randomised, controlled trial of the efficacy and safety of adapalene gel 0.1% and tretinoin cream 0.05% in patients with acne vulgaris (https://pubmed.ncbi.nlm.nih.gov/12095880/) — Documents that topical retinoids commonly cause erythema, dryness, desquamation and stinging/burning, supporting the claim that redness, flaking and stinging in the first weeks are expected with any real retinoid.
