AH-RIN Active Ingredients Risk & Safety Advisory Policy
Last Updated: 24 April 2026
Applies to: United Kingdom, European Union & All International Customers
This Active Ingredients Risk & Safety Advisory Policy explains the risks associated with using active skincare ingredients, including acids, retinoids, brightening agents, and botanical extracts.
This Policy forms part of the Medical & Cosmetic Disclaimer, Terms of Service, Parallel Import Notice, and Returns Policies.
1. Overview Modern Korean skincare includes a variety of powerful active ingredients designed to exfoliate, brighten, or rejuvenate the skin.
These ingredients may carry risks, especially for:
· Sensitive skin
· Reactive skin
· Customers using multiple actives
· Customers with underlying skin conditions
· Pregnant or breastfeeding customers
· Customers unfamiliar with proper layering
AH-RIN provides general information only, not medical or dermatological guidance.
2. Examples of High-Risk Active Ingredients Certain ingredients require careful use:
Exfoliating Acids
· AHA (Glycolic Acid, Lactic Acid, Mandelic Acid)
· BHA (Salicylic Acid)
· PHA (Gluconolactone, Lactobionic Acid)
Retinoids & Vitamin A Derivatives
· Retinol
· Retinal
· Retinyl palmitate
· Granactive retinoid
Vitamin C Types

· Derivative blends
Brightening & Lightening Agents

Peptides & Growth Factors (For sensitive skin, reactions may occur.)
Botanical Extracts
· Centella asiatica
· Mugwort
· Propolis

Ingredients may interact with one another or cause irritation depending on skin type.
3. Patch Testing Requirements All customers must perform a 24–48 hour patch test before full use. Apply a small amount to the:
· Inner forearm
· Behind the ear
· Jawline (optional low-risk area)
Stop immediately if you experience:
· Burning
· Redness
· Swelling
· Hives
· Rash
· Itchiness
Failure to patch test is considered customer misuse.
4. Layering Risks & Ingredient Interactions Some actives should not be combined in the same routine without professional advice. High-risk combinations include:
· Retinol + AHA/BHA
· Retinol + Vitamin C (L-AA)
· Vitamin C + Niacinamide (depending on sensitivity)
· Multiple exfoliating acids in one routine
· Harsh actives used during pregnancy/breastfeeding
· Using actives on broken or damaged skin
AH-RIN is not responsible for adverse reactions caused by improper layering or routine building.
5. Reactions vs. Defects Most reactions to actives are not defects. These include:
· Tingling
· Temporary redness
· Purging
· Dryness
· Light peeling
· Breakouts due to actives
· Sensitivity after overuse
These are normal responses for many active ingredients, especially during “adjustment periods.” Only proven manufacturing defects qualify under the Warranty & Defective Goods Policy.
6. Environmental & Storage Risks Customers must store products:
· Away from heat
· Away from sunlight

· With lids tightly closed
Heat exposure can cause:

9. International Formulation Differences Some brands create region-specific versions due to regulations. Therefore:
· Ingredients may vary by country

These differences are not defects.
