Radical Skincare's 20% off code is the main offer on this page and gives you a straightforward discount across the entire site. It is the strongest percentage code currently available, beating the 10% off first order code and the 5% off general code. Use it if you have a code to enter at checkout on the website.
Small baskets under $75. If you are a new customer, the 10% off first order code will give you a steeper discount than the 5% off code. On a $50 order, for example, the 10% off code leaves you with $45, saving $5, versus $47.50 with the 5% off code. If you are already a Radical Skincare customer, use the 5% off code instead. Signing up to the newsletter also qualifies you for free shipping on orders over $75, which may apply if you are close to that threshold.
Orders from $75 onwards. The 20% off code becomes the clear winner. On a $100 order, the 20% off code costs you $80, a saving of $20, compared with $95 using the 10% off first order code or $95 with the 5% off code. Once you reach $75, you also get free shipping if you are a newsletter subscriber.
Buying specific products. Radical Skincare currently has markdowns on two items. The Eye Therapy Kit carries a 15% discount and the Extreme Repair 50ml a 10% discount. These sales apply only to those individual products, not your whole basket. If you are buying the Eye Therapy Kit, compare its sale price to the price you would pay with any code: on a $60 kit, the 15% sale gives you $51, but the 20% off code gives you $48. The 20% off code wins unless you are a new customer applying the 10% off first order code, which then costs you $54. For the Extreme Repair cream, apply the same logic to your order total including that product.
Subscribing to Radical Skincare. A $15 discount applies if you set up a subscription to Radical Skincare's skincare box. This is a fixed saving rather than a percentage, so it works best on smaller baskets where a percentage code would give you less. On a $50 subscription order, the $15 off deal leaves you paying $35, beating the 10% off code ($45) and the 5% off code ($47.50). On larger orders the percentage codes overtake it: at $100, the $15 off subscription costs $85, but the 20% off code costs $80.
New customers. You have two dedicated options. The 10% off first order code applies to your entire order, whereas a separate offer gives you a free Youth Infusion Serum with any order when you are a new customer. Choose whichever saves you more money: the 10% off code if you are spending enough that its percentage discount beats the value of the serum, otherwise the free serum.
To decide between your options, calculate the final price under each and choose whichever leaves you paying less. The 20% off code and the first order 10% off code do not combine, so pick one or the other. The percentage codes do not stack with the sale markdowns on the Eye Therapy Kit and Extreme Repair cream, though you are welcome to apply a code to a basket that includes those discounted items.
Over the 12 months to October 2026, Radical Skincare listed 61 offers across the site: 16 codes and 45 sales and deals. Our team tested 16 offers at checkout in that period, so today's 20% off code is a solid result; the biggest percentage code in that window was 20% off (in June 2026) and the typical one was 10% off. Bigger sales have appeared: the largest single markdown or deal in the year was up to 40% off in January 2026.
