Offer questions

No. All three must be the same product: two C20 earn a third C20, and two Advanced Collagen earn a third Advanced Collagen. One C20 and one Advanced Collagen don't earn a free item.

No. Every two of the same product earn one free: add 4, get 2. You can use it on both products in the same order.

C-Lester Topical Vitamin C20 Serum $135 · Advanced Collagen Formula $118.

Yes. Shipping is free on orders of $125 or more, and two of either product comes to more than that. Free items don't count toward the $125.

C20 suits normal, oily and mature skin that already uses vitamin C comfortably. A brief, light tingle is normal. If your skin is sensitive or new to Vitamin C, start with C-Lester Topical Vitamin C10 Serum instead (it isn't part of this offer).

Keep the unopened ones closed, cool and out of the sun, and open the next one when the first is finished.
